+# Contributing to the NVM-e CLI
+
+Here you will find instructions on how to contribute to the NVM-Express command
+line interface.
+
+Contributions and new ideas are most welcome!
+
+**NOTE: If you do decide to implement code changes and contribute them,
+please make sure you agree your contribution can be made available
+under the [GPLv2-style License used for the NVMe CLI](https://github.com/linux-nvme/nvme-cli/blob/master/LICENSE).
+(SPDX-License-Identifier: GPL-2.0-or-later)**
+
+Because there are a few files licensed under GPL-2.0-only, the whole
+project is tagged as GPL-2.0-only and not as GPL-2.0-or-later.
+
+### Code Contributions
+
+Please feel free to use the github forums to ask for comments & questions on
+your code before submitting a pull request.  The NVMe CLI project uses the
+common *fork and merge* workflow used by most GitHub-hosted projects.
+
+### Bug Reports
+
+Bugs for the NVM Library project are tracked in our [GitHub Issues Database](https://github.com/linux-nvme/nvme-cli/issues).

+.SH "DESCRIPTION"
+.sp
+Submits an arbitrary NVMe admin command and returns the applicable results\&. This may be the simply the commands result and status, or may also include a buffer if the command returns one\&. This command does no interpretation of the opcodes or options\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned structure (if applicable) may be returned in one of several ways depending on the option flags; the structure may printed by the program as a hex dump, or may be returned as a raw buffer printed to stdout for another program to parse\&.
+.SH "OPTIONS"
+.PP
+\-o <opcode>, \-\-opcode=<opcode>
+.RS 4
+The NVMe opcode to send to the device in the command
+.RE
+.PP
+\-f <flags>, \-\-flags=<flags>
+.RS 4
+The NVMe command flags to send to the device in the command
+.RE
+.PP
+\-R <rsvd>, \-\-rsvd=<rsvd>
+.RS 4
+The value for the reserved field in the command\&.
+.RE
+.PP
+\-n <nsid>, \-\-namespace\-id=<nsid>
+.RS 4
+The value for the ns\-id in the command\&.
+.RE
+.PP
+\-\-cdw[2\-3,10\-15]=<cdw>
+.RS 4
+Specifies the command dword value for that specified entry in the command
+.RE
+.PP
+\-r, \-\-read, \-w, \-\-write
+.RS 4
+Used for the data\-direction for the command and required for commands sending/receiving data\&. Don\(cqt use both read and write at the same time\&.
+.RE
+.PP
+\-i <file>, \-\-input\-file=<file>
+.RS 4
+If the command is a data\-out (write) command, use this file to fill the buffer sent to the device\&. If no file is given, assumed to use STDIN\&.
+.RE
+.PP
+\-l <data\-len>, \-\-data\-len=<data\-len>
+.RS 4
+The data length for the buffer used for this command\&.
+.RE
+.PP
+\-m <data\-len>, \-\-metadata\-len=<data\-len>
+.RS 4
+The metadata length for the buffer used for this command\&.
+.RE
+.PP
+\-s, \-\-show\-cmd
+.RS 4
+Print out the command to be sent\&.
+.RE
+.PP
+\-d, \-\-dry\-run
+.RS 4
+Do not actually send the command\&. If want to use \-\-dry\-run option, \-\-show\-cmd option
+\fImust\fR
+be set\&. Otherwise \-\-dry\-run option will be
+\fIignored\fR\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw returned buffer to stdout if the command returns a structure\&.
+.RE
+.PP
+\-p, \-\-prefill
+.RS 4
+Prefill the buffer with a predetermined byte value\&. Defaults to 0\&. This may be useful if the data you are writing is shorter than the required buffer, and you need to pad it with a known value\&. It may also be useful if you need to confirm if a device is overwriting a buffer for a data\-in command\&.
+.RE
+.PP
+\-T, \-\-latency
+.RS 4
+Print out the latency the IOCTL took (in us)\&.
+.RE

+The following will run the admin command with opcode=6 and cdw10=1, which corresponds to an identify controller command\&. This example requires the data\-len param be 4096, which is the size of the returned structure\&. The \-r option is used because it is a data\-in command

+
+DESCRIPTION
+-----------
+Submits an arbitrary NVMe admin command and returns the applicable
+results. This may be the simply the commands result and status, or may
+also include a buffer if the command returns one. This command does no
+interpretation of the opcodes or options.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned structure (if applicable) may be returned in
+one of several ways depending on the option flags; the structure may
+printed by the program as a hex dump, or may be returned as a raw buffer
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-o <opcode>::
+--opcode=<opcode>::
+	The NVMe opcode to send to the device in the command
+
+-f <flags>::
+--flags=<flags>::
+	The NVMe command flags to send to the device in the command
+
+-R <rsvd>::
+--rsvd=<rsvd>::
+	The value for the reserved field in the command.
+
+-n <nsid>::
+--namespace-id=<nsid>::
+	The value for the ns-id in the command.
+
+--cdw[2-3,10-15]=<cdw>::
+	Specifies the command dword value for that specified entry in
+	the command
+
+-r::
+--read::
+-w::
+--write::
+	Used for the data-direction for the command and required for
+	commands sending/receiving data. Don't use both read and write
+	at the same time.
+
+-i <file>::
+--input-file=<file>::
+	If the command is a data-out (write) command, use this file
+	to fill the buffer sent to the device. If no file is given,
+	assumed to use STDIN.
+
+-l <data-len>::
+--data-len=<data-len>::
+	The data length for the buffer used for this command.
+
+-m <data-len>::
+--metadata-len=<data-len>::
+	The metadata length for the buffer used for this command.
+
+-s::
+--show-cmd::
+	Print out the command to be sent.
+
+-d::
+--dry-run::
+	Do not actually send the command. If want to use --dry-run option,
+	--show-cmd option _must_ be set. Otherwise --dry-run option will be
+	_ignored_.
+
+-b::
+--raw-binary::
+	Print the raw returned buffer to stdout if the command returns
+	a structure.
+
+-p::
+--prefill::
+	Prefill the buffer with a predetermined byte value. Defaults to 0.
+	This may be useful if the data you are writing is shorter
+	than the required buffer, and you need to pad it with a known
+	value. It may also be useful if you need to confirm if a device
+	is overwriting a buffer for a data-in command.
+
+-T::
+--latency::
+	Print out the latency the IOCTL took (in us).
+
+EXAMPLES
+--------
+* The following will run the admin command with opcode=6 and cdw10=1, which
+ corresponds to an identify controller command. This example requires the
+ data-len param be 4096, which is the size of the returned structure. The -r
+ option is used because it is a data-in command
++
+------------
+# nvme admin-passthru /dev/nvme0 --opcode=06 --data-len=4096 --cdw10=1 -r
+------------
++
+
+* Or if you want to save that structure to a file:
++
+------------
+# nvme admin-passthru /dev/nvme0 --opcode=06 --data-len=4096 --cdw10=1 -r -b > id_ns.raw

+===========================

+NAME
+----
+nvme-changed-ns-list-log - Send NVMe Changed Namespace List log page
+                           request, returns result and log.
+
+SYNOPSIS
+--------
+[verse]
+'nvme changed-ns-list-log' <device> [--raw-binary | -b]
+			[--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Retrieves the NVMe Changed Namespace List log page from an NVMe device and
+provides the returned structure.
+
+The <device> parameter is mandatory and must be a NVMe character device
+(ex: /dev/nvme0).
+
+On success, the returned Changed Namespace List log structure may be
+returned in one of several ways depending on the option flags; the
+structure may parsed by the program and printed in a readable format or
+the raw buffer may be printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-b::
+--raw-binary::
+	Print the raw Changed Namespace List log buffer to stdout.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Print the Changed Namespace List Log page in a human readable format:
++
+------------
+# nvme changed-ns-list-log /dev/nvme0
+------------
++
+
+* Print the raw Changed Namespace List log to a file:
++
+------------
+# nvme changed-ns-list-log /dev/nvme0 --raw-binary > log.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+NAME
+----
+nvme-cmdset-ind-id-ns - Send NVMe I/O Command Set Independent Identify Namespace, return result and structure.
+
+SYNOPSIS
+--------
+[verse]
+'nvme cmdset-ind-id-ns' <device> [--namespace-id=<nsid> | -n <nsid>]
+			[-b | --raw-binary]
+		    [--human-readable | -H]
+		    [--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an I/O Command Set Independent 
+identify namespace command and provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+If the character device is given, the `'--namespace-id'` option is
+mandatory, otherwise it will use the ns-id of the namespace for the block
+device you opened. For block devices, the ns-id used can be overridden
+with the same option.
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Retrieve the identify namespace structure for the given nsid. This
+	is required for the character devices, or overrides the block nsid
+	if given.
+
+-b::
+--raw-binary::
+	Print the raw buffer to stdout. Structure is not parsed by
+	program. This overrides the vendor specific and human readable options.
+
+-H::
+--human-readable::
+	This option will parse and format many of the bit fields
+	into human-readable formats.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:
++
+------------
+# nvme cmdset-ind-id-ns /dev/nvme0n1
+------------
++
+
+* If using the character device or overriding namespace id:
++
+------------
+# nvme cmdset-ind-id-ns /dev/nvme0 -n 1
+# nvme cmdset-ind-id-ns /dev/nvme0n1 -n 1
+# nvme cmdset-ind-id-ns /dev/nvme0 --namespace-id=1
+------------
++
+
+* Have the program return the raw structure in binary:
++
+------------
+# nvme cmdset-ind-id-ns /dev/nvme0n1 --raw-binary > id_ns.raw
+# nvme cmdset-ind-id-ns /dev/nvme0n1 -b > id_ns.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+.sp
+The Compare command reads the logical blocks specified by the command from the medium and compares the data read to a comparison data buffer transferred as part of the command\&. If the data read from the controller and the comparison data buffer are equivalent with no miscompares, then the command completes successfully\&. If there is any miscompare, the command completes with an error of Compare Failure\&. If metadata is provided, then a comparison is also performed for the metadata\&.

+DESCRIPTION
+-----------
+The Compare command reads the logical blocks specified by the command
+from the medium and compares the data read to a comparison data buffer
+transferred as part of the command. If the data read from the controller
+and the comparison data buffer are equivalent with no miscompares,
+then the command completes successfully. If there is any miscompare,
+the command completes with an error of Compare Failure. If metadata is
+provided, then a comparison is also performed for the metadata.

+DESCRIPTION
+-----------
+Read in the NVMe over Fabrics configuration from the specified JSON
+configuration file and allow to update or modify the contents.
+The JSON configuration file format is documented in
+https://github.com/linux-nvme/libnvme/doc/config-schema.json
+
+OPTIONS
+-------
+-R::
+--scan::
+	Additionally read the current configuration from sysfs.
+
+-M::
+--modify::
+	Add or modify entries in the configuration based on the values from
+        the commandline.
+
+-U::
+--update::
+	Write updated configuration into the JSON configuration file.
+
+-O::
+--dump::
+	Print out resulting JSON configuration file to stdout.
+
+-J <cfg>::
+--config=<cfg>::
+	Use the specified JSON configuration file instead of the
+	default @SYSCONFDIR@/nvme/config.json file or 'none' to not read in
+	an existing configuration file.
+
+-t <trtype>::
+--transport=<trtype>::
+	This field specifies the network fabric being used for
+	a NVMe-over-Fabrics network.  Current string values include:
++
+[]
+|=================
+|Value|Definition
+|rdma|The network fabric is an rdma network (RoCE, iWARP, Infiniband, basic rdma, etc)
+|fc  |The network fabric is a Fibre Channel network.
+|tcp |The network fabric is a TCP/IP network.
+|loop|Connect to a NVMe over Fabrics target on the local host
+|=================
+
+-n <subnqn>::
+--nqn <subnqn>::
+	This field specifies the name for the NVMe subsystem to connect to.
+
+-a <traddr>::
+--traddr=<traddr>::
+	This field specifies the network address of the Controller.
+	For transports using IP addressing (e.g. rdma) this should be an
+	IP-based address (ex. IPv4).
+
+-s <trsvcid>::
+--trsvcid=<trsvcid>::
+	This field specifies the transport service id.  For transports using IP
+	addressing (e.g. rdma) this field is the port number. By default, the IP
+	port number for the RDMA transport is 4420.
+
+-w <traddr>::
+--host-traddr=<traddr>::
+	This field specifies the network address used on the host to connect
+	to the Controller. For TCP, this sets the source address on the socket.
+
+-f <iface>::
+--host-iface=<iface>::
+	This field specifies the network interface used on the host to connect
+	to the Controller (e.g. IP eth1, enp2s0, enx78e7d1ea46da). This forces
+	the connection to be made on a specific interface instead of letting
+	the system decide.
+
+-q <hostnqn>::
+--hostnqn=<hostnqn>::
+	Overrides the default Host NQN that identifies the NVMe Host.
+	If this option is not specified, the default is read from
+	@SYSCONFDIR@/nvme/hostnqn first. If that does not exist, the autogenerated
+	NQN value from the NVMe Host kernel module is used next.
+	The Host NQN uniquely identifies the NVMe Host.
+

+--hostid=<hostid>::
+	UUID(Universally Unique Identifier) to be discovered which should be
+	formatted.
+
+-S <secret>::
+--dhchap-secret=<secret>::
+	NVMe In-band authentication secret; needs to be in ASCII format as
+	specified in NVMe 2.0 section 8.13.5.8 'Secret representation'.
+	If this option is not specified, the default is read from
+	@SYSCONFDIR@/nvme/hostkey. If that does not exist no in-band authentication
+	is attempted.
+
+-C <secret>::
+--dhchap-ctrl-secret=<secret>::
+	NVMe In-band authentication controller secret for bi-directional
+	authentication; needs to be in ASCII format as
+	specified in NVMe 2.0 section 8.13.5.8 'Secret representation'.
+	If not present bi-directional authentication is not attempted.
+
+-i <#>::
+--nr-io-queues=<#>::
+	Overrides the default number of I/O queues create by the driver.
+
+-W <#>::
+--nr-write-queues=<#>::
+	Adds additional queues that will be used for write I/O.
+
+-P <#>::
+--nr-poll-queues=<#>::
+	Adds additional queues that will be used for polling latency sensitive I/O.
+
+-Q <#>::
+--queue-size=<#>::
+	Overrides the default number of elements in the I/O queues created
+	by the driver.
+
+-k <#>::
+--keep-alive-tmo=<#>::
+	Overrides the default keep alive timeout (in seconds).
+
+-c <#>::
+--reconnect-delay=<#>::
+	Overrides the default delay (in seconds) before reconnect is attempted
+	after a connect loss.
+
+-l <#>::
+--ctrl-loss-tmo=<#>::
+	Overrides the default controller loss timeout period (in seconds).
+
+-D::
+--duplicate-connect::
+	Allows duplicated connections between same transport host and subsystem
+	port.
+
+-d::
+--disable-sqflow::
+	Disables SQ flow control to omit head doorbell update for submission
+	queues when sending nvme completions.
+
+-g::
+--hdr-digest::
+	Generates/verifies header digest (TCP).
+
+-G::
+--data-digest::
+	Generates/verifies data digest (TCP).

+.SH "DESCRIPTION"
+.sp
+Send one or more Discovery requests to a NVMe over Fabrics Discovery Controller, and create controllers for the returned discovery records\&.
+.sp
+If no parameters are given, then \fInvme connect\-all\fR will attempt to find a /usr/local/etc/nvme/discovery\&.conf file to use to supply a list of connect\-all commands to run\&. If no /usr/local/etc/nvme/discovery\&.conf file exists, the command will quit with an error\&.
+.sp
+Otherwise a specific Discovery Controller should be specified using the \-\-transport, \-\-traddr and if necessary the \-\-trsvcid and a Discovery request will be sent to the specified Discovery Controller\&.
+.sp
+See the documentation for the nvme\-discover(1) command for further background\&.

+DESCRIPTION
+-----------
+Send one or more Discovery requests to a NVMe over Fabrics Discovery
+Controller, and create controllers for the returned discovery records.
+
+If no parameters are given, then 'nvme connect-all' will attempt to
+find a @SYSCONFDIR@/nvme/discovery.conf file to use to supply a list of
+connect-all commands to run. If no @SYSCONFDIR@/nvme/discovery.conf file
+exists, the command will quit with an error.
+
+Otherwise a specific Discovery Controller should be specified using the
+--transport, --traddr and if necessary the --trsvcid and a Discovery
+request will be sent to the specified Discovery Controller.
+
+See the documentation for the nvme-discover(1) command for further
+background.
+
+OPTIONS
+-------
+-t <trtype>::
+--transport=<trtype>::
+	This field specifies the network fabric being used for
+	a NVMe-over-Fabrics network.  Current string values include:
++
+[]
+|=================
+|Value|Definition
+|rdma|The network fabric is an rdma network (RoCE, iWARP, Infiniband, basic rdma, etc)
+|fc  |*WIP* The network fabric is a Fibre Channel network.
+|tcp |The network fabric is a TCP/IP network.
+|loop|Connect to a NVMe over Fabrics target on the local host
+|=================
+
+-n <subnqn>::
+--nqn <subnqn>::
+	This field specifies the name for the NVMe subsystem to connect to.
+
+-a <traddr>::
+--traddr=<traddr>::
+	This field specifies the network address of the Discovery Controller.
+	For transports using IP addressing (e.g. rdma) this should be an
+	IP-based address (ex. IPv4).
+
+-s <trsvcid>::
+--trsvcid=<trsvcid>::
+	This field specifies the transport service id.  For transports using IP
+	addressing (e.g. rdma) this field is the port number. By default, the IP
+	port number for the RDMA transport is 4420.
+
+-w <traddr>::
+--host-traddr=<traddr>::
+	This field specifies the network address used on the host to connect
+	to the Controller. For TCP, this sets the source address on the socket.
+
+-f <iface>::
+--host-iface=<iface>::
+	This field specifies the network interface used on the host to connect
+	to the Controller (e.g. IP eth1, enp2s0, enx78e7d1ea46da). This forces
+	the connection to be made on a specific interface instead of letting
+	the system decide.
+
+-q <hostnqn>::
+--hostnqn=<hostnqn>::
+	Overrides the default Host NQN that identifies the NVMe Host.
+	If this option is not specified, the default is read from
+	@SYSCONFDIR@/nvme/hostnqn first. If that does not exist, the
+	autogenerated NQN value from the NVMe Host kernel module is used next.
+	The Host NQN uniquely identifies the NVMe Host, and may be used by the
+	the Discovery Controller to control what NVMe Target resources are
+	allocated to the NVMe Host for a connection.
+
+-I <hostid>::
+--hostid=<hostid>::
+	UUID(Universally Unique Identifier) to be discovered which should be
+	formatted.
+
+-r <filename>::
+--raw=<filename>::
+	This field will take the output of the 'nvme connect-all' command
+	and dump it to a raw binary file. By default 'nvme connect-all' will
+	dump the output to stdout.
+
+-C <cfg>::
+--config-file=<cfg>::
+	Use the specified JSON configuration file instead of the
+	default @SYSCONFDIR@/nvme/config.json file or 'none' to not read in
+	an existing configuration file. The JSON configuration file
+	format is documented in
+	https://github.com/linux-nvme/libnvme/doc/config-schema.json
+
+-k <#>::
+--keep-alive-tmo=<#>::
+	Overrides the default keep alive timeout (in seconds). This
+	option will be ignored for discovery, but will be passed on to
+	the subsequent connect call.
+
+-c <#>::
+--reconnect-delay=<#>::
+	Overrides the default delay (in seconds) before reconnect is attempted
+	after a connect loss.
+
+-l <#>::
+--ctrl-loss-tmo=<#>::
+	Overrides the default controller loss timeout period (in seconds).
+
+-g::
+--hdr-digest::
+	Generates/verifies header digest (TCP).
+
+-G::
+--data-digest::
+	Generates/verifies data digest (TCP).
+
+-i <#>::
+--nr-io-queues=<#>::
+	Overrides the default number of I/O queues create by the driver.
+	This option will be ignored for discovery, but will be passed on
+	to the subsequent connect call.
+
+-W <#>::
+--nr-write-queues=<#>::
+	Adds additional queues that will be used for write I/O.
+
+-P <#>::
+--nr-poll-queues=<#>::
+	Adds additional queues that will be used for polling latency sensitive I/O.
+
+-Q <#>::
+--queue-size=<#>::
+	Overrides the default number of elements in the I/O queues created
+	by the driver. This option will be ignored for discovery, but will be
+	passed on to the subsequent connect call.
+
+-p::
+--persistent::
+	Don't remove the discovery controller after retrieving the discovery
+	log page.
+
+-S::
+--quiet::
+	Suppress error messages.
+
+-O::
+--dump-config::
+	Print out resulting JSON configuration file to stdout.
+
+
+EXAMPLES
+--------
+* Connect to all records returned by the Discover Controller with IP4 address
+192.168.1.3 for all resources allocated for NVMe Host name host1-rogue-nqn on
+the RDMA network. Port 4420 is used by default:
++
+------------
+# nvme connect-all --transport=rdma --traddr=192.168.1.3 \
+--hostnqn=host1-rogue-nqn
+------------
++
+* Issue a 'nvme connect-all' command using a @SYSCONFDIR@/nvme/discovery.conf file:
++
+-----------
+# Machine default 'nvme discover' commands.  Query the
+# Discovery Controller's two ports (some resources may only
+# be accessible on a single port).  Note an official
+# nqn (Host) name defined in the NVMe specification is being used
+# in this example.
+-t rdma -a 192.168.69.33 -s 4420 -q nqn.2014-08.com.example:nvme:nvm-subsystem-sn-d78432
+-t rdma -a 192.168.1.4   -s 4420 -q nqn.2014-08.com.example:nvme:nvm-subsystem-sn-d78432

+DESCRIPTION
+-----------
+Create a transport connection to a remote system (specified by --traddr and
+--trsvcid) and create a NVMe over Fabrics controller for the NVMe subsystem
+specified by the --nqn option.
+
+OPTIONS
+-------
+-t <trtype>::
+--transport=<trtype>::
+	This field specifies the network fabric being used for
+	a NVMe-over-Fabrics network.  Current string values include:
++
+[]
+|=================
+|Value|Definition
+|rdma|The network fabric is an rdma network (RoCE, iWARP, Infiniband, basic rdma, etc)
+|fc  |*WIP* The network fabric is a Fibre Channel network.
+|tcp |The network fabric is a TCP/IP network.

+	to the Controller (e.g. IP eth1, enp2s0, enx78e7d1ea46da). This forces
+	the connection to be made on a specific interface instead of letting
+	the system decide.
+
+-q <hostnqn>::
+--hostnqn=<hostnqn>::
+	Overrides the default Host NQN that identifies the NVMe Host.
+	If this option is not specified, the default is read from

+	format is documented in
+	https://github.com/linux-nvme/libnvme/doc/config-schema.json
+
+-S <secret>::
+--dhchap-secret=<secret>::
+	NVMe In-band authentication secret; needs to be in ASCII format as
+	specified in NVMe 2.0 section 8.13.5.8 'Secret representation'.
+	If this option is not specified, the default is read from
+	@SYSCONFDIR@/nvme/hostkey. If that does not exist no in-band authentication
+	is attempted.
+
+-C <secret>::

+DESCRIPTION
+-----------
+For the NVMe device given, sends a namespace management command to create
+the namespace with the requested settings. On success, the namespace
+identifier assigned by the controller is returned.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+OPTIONS
+-------
+-s::
+--nsze::
+	The namespace size.
+
+-c::
+--ncap::
+	The namespace capacity.
+
+-f::
+--flbas::
+	The namespace formatted logical block size setting.
+	Conflicts with --block-size argument.
+
+-d::
+--dps::
+	The data protection settings.
+
+-m::
+--nmic::
+	Namespace multipath and sharing capabilities.
+
+-a::
+--anagrp-id::
+	ANA Group Identifier. If this value is 0h specifies
+	that the controller determines the value to use
+
+-i <nvmsetid>::
+--nvmset-id=<nvmsetid>::
+	This field specifies the identifier of the NVM Set.
+
+-y <command_set_identifier>::
+--csi=<command_set_identifier>::
+	This field specifies the identifier of command set.
+	if not issued, NVM Command Set will be selected.
+
+-l <lbstm>::
+--lbstm=<lbstm>::
+	Logical Block Storage Tag Mask for end-to-end protection.
+
+-b::
+--block-size::
+	Target block size the new namespace should be formatted as. Potential FLBAS
+  values will be values will be scanned and the lowest numbered will be
+  selected for the create-ns operation. Conflicts with --flbas argument.
+
+-S::
+--nsze-si::
+	The namespace size (NSZE) in standard SI units.
+	The value SI suffixed is divided by the namespace LBA size to set as NSZE.
+	If the value not suffixed it is set as same with the nsze option.
+
+-C::
+--ncap-si::
+	The namespace capacity (NCAP) in standard SI units.
+	The value SI suffixed is divided by the namespace LBA size to set as NCAP.
+	If the value not suffixed it is set as same with the ncap option.
+
+EXAMPLES

+nvme-device-self-test - Perform the necessary tests to observe the performance and the parameters
+
+SYNOPSIS
+--------
+[verse]
+'nvme device-self-test' <device> [--namespace-id=<NUM> | -n <NUM>]
+			[--self-test-code=<NUM> | -s <NUM>]  [--wait | -w]
+
+DESCRIPTION
+-----------
+Initiates the required test based on the user input.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the corresponding test is initiated.
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+	Indicate the namespace in which the device self-test has to be carried out
+
+-s <NUM>::
+--self-test-code=<NUM>::
+        This field specifies the action taken by the device self-test command :
+         0h: Show current state of device self-test operation
+         1h: Start a short device self-test operation
+         2h: Start a extended device self-test operation
+         eh: Start a vendor specific device self-test operation
+         fh: Abort the device self-test operation
+	Default is 0h.
+
+-w::
+--wait::
+	Wait for the device self test to complete before exiting
+	The device self-test is aborted by SIGINT signal interrupt for the wait
+	The option is ignored if the abort self-test code option specified.

+.SH "DESCRIPTION"
+.sp
+Send Discovery Information Management (DIM) command to one or more Discovery Controllers\&. The DIM command allows performing two types of tasks: register or deregister\&.
+.sp
+The DIM command is used to explicitly register with Discovery Controllers (DC), especially with Central Discovery Controllers (CDC)\&. CDCs maintain a database (DB) of all the Hosts and Storage Subsystems in a network\&. The register task is used to add a host to the CDC\(cqs DB\&. The deregister task is used to remove a host from the CDC\(cqs DB\&.
+.sp
+During a register operation the host will send mandatory information such as the Host\(cqs NQN and ID, as well as the Host\(cqs hostname and the Operating System\(cqs version that it is running on\&. There is also an optional Host Symbolic Name that can be registered with the CDC\&.
+.sp
+This command can only be applied to existing DC connections previously created with the nvme\-discover(1) command using the \-\-persistent option\&.
+.SH "OPTIONS"
+.PP
+\-t <task>, \-\-task <task>
+.RS 4
+The task to perform: "register" or "deregister"\&.
+.RE

+\-n <subnqn>, \-\-nqn <nqn>
+.RS 4
+The DIM command will be sent to the Discovery Controller (DC) matching this NQN\&. A list of comma\-separated NQNs can be supplied to apply the command to more than one DC\&.
+.RE
+.PP
+\-d <device>, \-\-device <device>
+.RS 4
+The DIM command will be sent to the Discovery Controllers (DC) associated with this NVMe device handle\&. A list of comma\-separated device handles can be supplied to apply the command to more than one DC\&.

+nvme-dim - Send Discovery Information Management command to one or more Discovery Controllers.
+
+SYNOPSIS

+		[--device=<device> | -d <device>]
+
+DESCRIPTION
+-----------
+Send Discovery Information Management (DIM) command to one or more Discovery
+Controllers. The DIM command allows performing two types of tasks: register or
+deregister.
+
+The DIM command is used to explicitly register with Discovery Controllers (DC),
+especially with Central Discovery Controllers (CDC). CDCs maintain a database (DB)
+of all the Hosts and Storage Subsystems in a network. The register task is used
+to add a host to the CDC's DB. The deregister task is used to remove a host from
+the CDC's DB.
+
+During a register operation the host will send mandatory information such as the
+Host's NQN and ID, as well as the Host's hostname and the Operating System's
+version that it is running on. There is also an optional Host Symbolic Name
+that can be registered with the CDC.
+
+This command can only be applied to existing DC connections previously created
+with the nvme-discover(1) command using the --persistent option.
+
+OPTIONS
+-------
+-t <task>::
+--task <task>::
+	The task to perform: "register" or "deregister".
+

+===================
+
+NAME
+----
+nvme-dir-receive - Send a directive receive command, returns applicable results
+
+SYNOPSIS
+--------
+[verse]
+'nvme dir-receive' <device> [--namespace-id=<nsid> | -n <nsid>]
+			  [--data-len=<data-len> | -l <data-len>]
+			  [--dir-type=<dtype> | -D <dtype>]
+			  [--dir-spec=<dspec> | -S <dspec>]
+			  [--dir-oper=<doper> | -O <doper>]
+			  [--req-resource=<nsr> | -r <nsr>]
+			  [--human-readable | -H]
+			  [--raw-binary | -b]
+
+DESCRIPTION
+-----------
+Submits an NVMe Directive Receive admin command and returns the applicable
+results. This may be the combination of directive type, and operation, as 
+well as number of requested resource if specific operation needs it.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned directive's parameter structure (if applicable) is 
+returned in one of several ways depending on the option flags; the
+structure may parsed by the program and printed in a readable format
+if it is a known structure, displayed in hex, or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::

+--------
+* Identify directive type supported :

+# nvme dir-receive /dev/nvme0 --dir-type 0 --dir-oper 1 --human-readable
+------------
++
+
+* Get stream directive parameters :

+
+DESCRIPTION
+-----------
+Submits an NVMe Directive Send admin command and returns the applicable
+results. This may be the combination of directive type, and operation, as
+well as target directive and its enable/disable status of the operation,
+if specific operation needs it.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned directive's parameter structure (if applicable) is
+returned in one of several ways depending on the option flags; the
+structure may parsed by the program and printed in a readable format
+if it is a known structure, displayed in hex, or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Retrieve the feature for the given nsid. This is optional and
+	most features do not use this value.
+
+-D <dtype>::
+--dir-type=<dtype>::
+	Directive type	
+
+-S <dspec>::
+--dir-spec=<dspec>::
+	Directive specific	
+
+-O <doper>::
+--dir-oper=<doper>::
+	Directive operation	
+
+-T <tdir>::
+--target-dir=<nsr>::
+	Target directive of the operation
+
+-e <endir>::
+--endir=<endir>::
+	Target directive enable(1) or disable (0) operation
+

+|1|Default 
+|2|Saved
+|3|Supported capabilities
+|4–7|Reserved
+|==================
+
+-l <data-len>::
+--data-len=<data-len>::
+	The data length for the buffer returned for this feature. Most
+	known features do not use this value. The exception is LBA
+	Range Type
+
+-b::
+--raw-binary::
+	Print the raw receive buffer to stdout if the command returns
+	a structure.
+
+-H::
+--human-readable::
+	Print the decoded receive buffer to stdout if the command returns
+	a structure.
+
+EXAMPLES
+--------
+* Enable streams directive :
++
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 0 --dir-oper 1 --target-dir 1 --endir 1
+------------
++
+
+* Disable streams directive :
++
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 0 --dir-oper 1 --target-dir 1 --endir 0
+------------
++
+
+* Release all allocated streams resource :
++
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 1 --dir-oper 2
+------------
++
+
+* Release stream ID 3 :
++
+------------
+# nvme dir-send /dev/nvme0 --dir-type 1 --dir-oper 1 --dir-spec 3
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+.SH "DESCRIPTION"
+.sp
+Send one or more Get Log Page requests to a NVMe\-over\-Fabrics Discovery Controller\&.
+.sp
+If no parameters are given, then \fInvme discover\fR will attempt to find a /usr/local/etc/nvme/discovery\&.conf file to use to supply a list of Discovery commands to run\&. If no /usr/local/etc/nvme/discovery\&.conf file exists, the command will quit with an error\&.
+.sp
+Otherwise, a specific Discovery Controller should be specified using the \-\-transport, \-\-traddr, and if necessary the \-\-trsvcid flags\&. A Discovery request will then be sent to the specified Discovery Controller\&.
+.SH "BACKGROUND"
+.sp
+The NVMe\-over\-Fabrics specification defines the concept of a Discovery Controller that an NVMe Host can query on a fabric network to discover NVMe subsystems contained in NVMe Targets which it can connect to on the network\&. The Discovery Controller will return Discovery Log Pages that provide the NVMe Host with specific information (such as network address and unique subsystem NQN) the NVMe Host can use to issue an NVMe connect command to connect itself to a storage resource contained in that NVMe subsystem on the NVMe Target\&.
+.sp
+Note that the base NVMe specification defines the NQN (NVMe Qualified Name) format which an NVMe endpoint (device, subsystem, etc) must follow to guarantee a unique name under the NVMe standard\&. In particular, the Host NQN uniquely identifies the NVMe Host, and may be used by the the Discovery Controller to control what NVMe Target resources are allocated to the NVMe Host for a connection\&.
+.sp
+A Discovery Controller has it\(cqs own NQN defined in the NVMe\-over\-Fabrics specification, \fBnqn\&.2014\-08\&.org\&.nvmexpress\&.discovery\fR\&. All Discovery Controllers must use this NQN name\&. This NQN is used by default by nvme\-cli for the \fIdiscover\fR command\&.

+<div class="sectionbody">

+<div class="paragraph"><p>The NVMe-over-Fabrics specification defines the concept of a

+Discovery Controller that an NVMe Host can query on a fabric

+network to discover NVMe subsystems contained in NVMe Targets

+which it can connect to on the network.  The Discovery Controller

+will return Discovery Log Pages that provide the NVMe Host

+with specific information (such as network address and unique

+subsystem NQN) the NVMe Host can use to issue an

+NVMe connect command to connect itself to a storage resource

+contained in that NVMe subsystem on the NVMe Target.</p></div>

+<div class="paragraph"><p>Note that the base NVMe specification defines the NQN (NVMe Qualified

+Name) format which an NVMe endpoint (device, subsystem, etc) must

+follow to guarantee a unique name under the NVMe standard.

+In particular, the Host NQN uniquely identifies the NVMe Host, and

+may be used by the the Discovery Controller to control what NVMe Target

+resources are allocated to the NVMe Host for a connection.</p></div>

+<div class="paragraph"><p>A Discovery Controller has it&#8217;s own NQN defined in the NVMe-over-Fabrics

+specification, <strong>nqn.2014-08.org.nvmexpress.discovery</strong>.  All Discovery

+Controllers must use this NQN name. This NQN is used by default by

+nvme-cli for the <em>discover</em> command.</p></div>

+DESCRIPTION
+-----------
+Send one or more Get Log Page requests to a NVMe-over-Fabrics Discovery
+Controller.
+
+If no parameters are given, then 'nvme discover' will attempt to
+find a @SYSCONFDIR@/nvme/discovery.conf file to use to supply a list of
+Discovery commands to run.  If no @SYSCONFDIR@/nvme/discovery.conf file
+exists, the command will quit with an error.
+
+Otherwise, a specific Discovery Controller should be specified using the
+--transport, --traddr, and if necessary the --trsvcid flags. A Discovery
+request will then be sent to the specified Discovery Controller.
+
+BACKGROUND
+----------
+The NVMe-over-Fabrics specification defines the concept of a
+Discovery Controller that an NVMe Host can query on a fabric
+network to discover NVMe subsystems contained in NVMe Targets
+which it can connect to on the network.  The Discovery Controller
+will return Discovery Log Pages that provide the NVMe Host
+with specific information (such as network address and unique
+subsystem NQN) the NVMe Host can use to issue an
+NVMe connect command to connect itself to a storage resource
+contained in that NVMe subsystem on the NVMe Target.
+
+Note that the base NVMe specification defines the NQN (NVMe Qualified
+Name) format which an NVMe endpoint (device, subsystem, etc) must
+follow to guarantee a unique name under the NVMe standard.
+In particular, the Host NQN uniquely identifies the NVMe Host, and
+may be used by the the Discovery Controller to control what NVMe Target
+resources are allocated to the NVMe Host for a connection.
+
+A Discovery Controller has it's own NQN defined in the NVMe-over-Fabrics
+specification, *nqn.2014-08.org.nvmexpress.discovery*.  All Discovery
+Controllers must use this NQN name. This NQN is used by default by
+nvme-cli for the 'discover' command.
+
+OPTIONS
+-------
+-t <trtype>::
+--transport=<trtype>::
+	This field specifies the network fabric being used for
+	a NVMe-over-Fabrics network.  Current string values include:
++
+[]
+|=================
+|Value|Definition
+|rdma|The network fabric is an rdma network (RoCE, iWARP, Infiniband, basic rdma, etc)
+|fc  |*WIP* The network fabric is a Fibre Channel network.
+|tcp |The network fabric is a TCP/IP network.
+|loop|Connect to a NVMe over Fabrics target on the local host
+|=================
+
+-n <subnqn>::
+--nqn <subnqn>::
+	This field specifies the name for the NVMe subsystem to connect to.
+
+-a <traddr>::
+--traddr=<traddr>::
+	This field specifies the network address of the Discovery Controller.
+	For transports using IP addressing (e.g. rdma) this should be an
+	IP-based (ex. IPv4) address.
+
+-s <trsvcid>::
+--trsvcid=<trsvcid>::
+	This field specifies the transport service id.  For transports using IP
+	addressing (e.g. rdma) this field is the port number. By default, the IP
+	port number for the RDMA transport is 4420.
+
+-w <traddr>::
+--host-traddr=<traddr>::
+	This field specifies the network address used on the host to connect
+	to the Controller. For TCP, this sets the source address on the socket.
+
+-f <iface>::
+--host-iface=<iface>::
+	This field specifies the network interface used on the host to connect
+	to the Controller (e.g. IP eth1, enp2s0, enx78e7d1ea46da). This forces
+	the connection to be made on a specific interface instead of letting
+	the system decide.
+
+-q <hostnqn>::
+--hostnqn=<hostnqn>::
+	Overrides the default host NQN that identifies the NVMe Host.
+	If this option is not specified, the default is read from
+	@SYSCONFDIR@/nvme/hostnqn first. If that does not exist, the
+	autogenerated NQN value from the NVMe Host kernel module is used next.
+
+-I <hostid>::
+--hostid=<hostid>::
+	UUID(Universally Unique Identifier) to be discovered which should be
+	formatted.
+
+-r <filename>::
+--raw=<filename>::
+	This field will take the output of the 'nvme discover' command
+	and dump it to a raw binary file. By default 'nvme discover' will
+	dump the output to stdout.
+
+-d <device>::
+--device=<device>::
+	This field takes a device as input. Device is in the format of nvme*,
+	eg. nvme0, nvme1
+
+-C <cfg>::
+--config-file=<cfg>::
+	Use the specified JSON configuration file instead of the
+	default @SYSCONFDIR@/nvme/config.json file or 'none' to not read in
+	an existing configuration file. The JSON configuration file
+	format is documented in
+	https://github.com/linux-nvme/libnvme/doc/config-schema.json
+
+-k <#>::
+--keep-alive-tmo=<#>::
+	Overrides the default timeout (in seconds) for keep alive.
+	This option will be ignored for the discovery, and it is only
+	implemented for completeness.
+
+-c <#>::
+--reconnect-delay=<#>::
+	Overrides the default delay (in seconds) before reconnect is attempted
+	after a connect loss.
+
+-l <#>::
+--ctrl-loss-tmo=<#>::
+	Overrides the default controller loss timeout period (in seconds).
+
+-g::
+--hdr_digest::
+	Generates/verifies header digest (TCP).
+
+-G::
+--data_digest::
+	Generates/verifies data digest (TCP).
+
+-i <#>::
+--nr-io-queues=<#>::
+	Overrides the default number of I/O queues create by the driver.
+	This option will be ignored for the discovery, and it is only
+	implemented for completeness.
+
+-W <#>::
+--nr-write-queues=<#>::
+	Adds additional queues that will be used for write I/O.
+
+-P <#>::
+--nr-poll-queues=<#>::
+	Adds additional queues that will be used for polling latency sensitive I/O.
+
+-Q <#>::
+--queue-size=<#>::
+	Overrides the default number of elements in the I/O queues created
+	by the driver which can be found at drivers/nvme/host/fabrics.h.
+	This option will be ignored for the discovery, and it is only
+	implemented for completeness.
+
+-p::
+--persistent::
+	Persistent discovery connection.
+
+-S::
+--quiet::
+	Suppress already connected errors.
+
+-O::
+--dump-config::
+	Print out resulting JSON configuration file to stdout.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+--force::
+	Disable the built-in persistent discover connection rules.
+	Combined with --persistent flag, always create new
+	persistent discovery connection.
+
+EXAMPLES
+--------
+* Query the Discover Controller with IP4 address 192.168.1.3 for all
+resources allocated for NVMe Host name host1-rogue-nqn on the RDMA network.
+Port 4420 is used by default:
++
+------------
+# nvme discover --transport=rdma --traddr=192.168.1.3 \
+--hostnqn=host1-rogue-nqn
+------------
++
+* Issue a 'nvme discover' command using a @SYSCONFDIR@/nvme/discovery.conf file:
++
+-----------
+# Machine default 'nvme discover' commands.  Query the
+# Discovery Controller's two ports (some resources may only
+# be accessible on a single port).  Note an official
+# nqn (Host) name defined in the NVMe specification is being used
+# in this example.

+.sp
+For the NVMe device given, sends an Data Set Management command and provides the result and returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&. If the character device is given, the \*(Aq\-\-namespace\-id\*(Aq option is mandatory, otherwise it will use the ns\-id of the namespace for the block device you opened\&. For block devices, the ns\-id used can be overridden with the same option\&.
+.sp
+You must specify at least one of the values for range list\&. If the range lists provided do not list the same number of elements, the default values for the remaining in the range will be set to 0\&.
+.sp
+The command dword 11 may be provided at the command line\&. For convenience, the current defined attributes (discard, integral read/write) for a data\-set management have flags\&. If cdw11 is specified, this will override any settings from the flags may have provided\&.

+
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an Data Set Management command and
+provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+If the character device is given, the `'--namespace-id'` option is
+mandatory, otherwise it will use the ns-id of the namespace for the block
+device you opened. For block devices, the ns-id used can be overridden
+with the same option.
+
+You must specify at least one of the values for range list. If the range
+lists provided do not list the same number of elements, the default
+values for the remaining in the range will be set to 0.
+
+The command dword 11 may be provided at the command line. For convenience,
+the current defined attributes (discard, integral read/write) for a
+data-set management have flags. If cdw11 is specified, this will override
+any settings from the flags may have provided.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Sends the command with the requested nsid. This is required for the
+	character devices, or overrides the block nsid if given.

+
+-s <slba-list,>::

+	Comma separated list of the starting block in each range
+
+-d <deallocate>::

+	Attribute Deallocate.
+
+-w <write>::

+nvme-endurance-log - Send NVMe Endurance log page request, returns result and log
+
+SYNOPSIS
+--------
+[verse]
+'nvme endurance-log' <device> [--group-id=<group> | -g <group>]
+			[--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Retrieves the NVMe Endurance log page from an NVMe device and provides the returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned endurance log structure may be returned in one of
+several ways depending on the option flags; the structure may parsed by
+the program and printed in a readable format, the raw buffer may be
+printed to stdout for another program to parse, or reported in json format.
+
+OPTIONS
+-------
+-g <group>::
+--group-id=<group>::
+	The endurance group identifier.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Print the Endurance log page in a human readable format:
++
+------------
+# nvme endurance-log /dev/nvme0
+------------
++
+
+* Print the raw Endurance log to a file:
++
+------------
+# nvme endurance-log /dev/nvme0 --output=binary > endurance_log.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+.SH "DESCRIPTION"
+.sp
+Retrieves NVMe Error log page from an NVMe device and provides the returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned error log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.
+.SH "OPTIONS"
+.PP
+\-e <entries>, \-\-log\-entries=<entries>
+.RS 4
+Specifies how many log entries the program should request from the device\&. This must be at least one, and shouldn\(cqt exceed the device\(cqs capabilities\&. Defaults to 64 log entries\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw error log buffer to stdout\&.
+.RE
+.PP
+\-o <format>, \-\-output\-format=<format>
+.RS 4
+Set the reporting format to
+\fInormal\fR,
+\fIjson\fR, or
+\fIbinary\fR\&. Only one output format can be used at a time\&.

+nvme-error-log - Send NVME Error log page request, return result and log
+
+SYNOPSIS

+[verse]
+'nvme error-log' <device>  [--log-entries=<entries> | -e <entries>]
+			 [--raw-binary | -b]
+			 [--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Retrieves NVMe Error log page from an NVMe device and provides the
+returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned error log structure may be returned in one of
+several ways depending on the option flags; the structure may parsed by
+the program and printed in a readable format or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-e <entries>::
+--log-entries=<entries>::
+	Specifies how many log entries the program should request from
+	the device. This must be at least one, and shouldn't exceed the
+	device's capabilities. Defaults to 64 log entries.
+
+-b::
+--raw-binary::
+	Print the raw error log buffer to stdout.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+
+EXAMPLES
+--------
+* Get the error log and print it in a human readable format:
++
+------------
+# nvme error-log /dev/nvme0
+------------
++
+
+* Print the raw output to a file:
++
+------------
+# nvme error-log /dev/nvme0 --raw-binary > error_log.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, send an nvme Format Namespace admin command and provides the results\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&. If the character device is given, and the controller does not support formatting of particular namespaces (ID_CTRL\&.FNA bit 0 enabled), then all namespaces will be formatted\&. If FNA is disabled, then the namespace identifier must be specified with the \fInamespace\-id\fR option; specify a value of 0xffffffff to send the format to all namespaces\&. If the block device is given, the namespace identifier will default to the namespace ID of the block device given, but can be overridden with the same option\&.
+.sp
+Note, the numeric suffix on the character device, for example the \fI0\fR in /dev/nvme0, does NOT indicate this device handle is the parent controller of any namespaces with the same suffix\&. The namespace handle\(cqs numeral may be coming from the subsystem identifier, which is independent of the controller\(cqs identifier\&. Do not assume any particular device relationship based on their names\&. If you do, you may irrevocably erase data on an unintended device\&.
+.sp
+On success, the program will automatically issue BLKRRPART ioctl to force rescanning the namespaces\&. If the driver is recent enough, this will automatically update the physical block size\&. If it is not recent enough, you will need to remove and rescan your device some other way for the new block size to be visible, if the size was changed with this command\&.
+.SH "OPTIONS"

+<div class="paragraph"><p>For the NVMe device given, send an nvme Format Namespace admin command

+and provides the results.</p></div>

+<div class="paragraph"><p>The &lt;device&gt; parameter is mandatory and may be either the NVMe character

+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

+If the character device is given, and the controller does not support

+formatting of particular namespaces (ID_CTRL.FNA bit 0 enabled), then all

+namespaces will be formatted. If FNA is disabled, then the namespace

+identifier must be specified with the <em>namespace-id</em> option; specify a

+value of 0xffffffff to send the format to all namespaces. If the block

+device is given, the namespace identifier will default to the namespace

+ID of the block device given, but can be overridden with the same option.</p></div>

+<div class="paragraph"><p>Note, the numeric suffix on the character device, for example the <em>0</em> in

+/dev/nvme0, does NOT indicate this device handle is the parent controller

+of any namespaces with the same suffix. The namespace handle&#8217;s numeral

+may be coming from the subsystem identifier, which is independent of the

+controller&#8217;s identifier. Do not assume any particular device relationship

+based on their names. If you do, you may irrevocably erase data on an

+unintended device.</p></div>

+<div class="paragraph"><p>On success, the program will automatically issue BLKRRPART ioctl to

+force rescanning the namespaces. If the driver is recent enough, this will

+automatically update the physical block size. If it is not recent enough,

+you will need to remove and rescan your device some other way for the

+new block size to be visible, if the size was changed with this command.</p></div>

+NAME
+----
+nvme-format - Format an NVMe device
+
+SYNOPSIS
+--------
+[verse]
+'nvme format' <device> [--namespace-id=<nsid> | -n <nsid>]
+		    [--lbaf=<lbaf> | -l <lbaf>]
+		    [--block-size=<block size | -b <block size>]
+		    [--ses=<ses> | -s <ses>]
+		    [--pil=<pil> | -p <pil>]
+		    [--pi=<pi> | -i <pi>]
+		    [--ms=<ms> | -m <ms>]
+		    [--reset | -r ]
+		    [--force ]
+		    [--timeout=<timeout> | -t <timeout> ]
+
+DESCRIPTION
+-----------
+For the NVMe device given, send an nvme Format Namespace admin command
+and provides the results.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+If the character device is given, and the controller does not support
+formatting of particular namespaces (ID_CTRL.FNA bit 0 enabled), then all
+namespaces will be formatted. If FNA is disabled, then the namespace
+identifier must be specified with the 'namespace-id' option; specify a
+value of 0xffffffff to send the format to all namespaces. If the block
+device is given, the namespace identifier will default to the namespace
+ID of the block device given, but can be overridden with the same option.
+
+Note, the numeric suffix on the character device, for example the '0' in
+/dev/nvme0, does NOT indicate this device handle is the parent controller
+of any namespaces with the same suffix. The namespace handle's numeral
+may be coming from the subsystem identifier, which is independent of the
+controller's identifier. Do not assume any particular device relationship
+based on their names. If you do, you may irrevocably erase data on an
+unintended device.
+
+On success, the program will automatically issue BLKRRPART ioctl to
+force rescanning the namespaces. If the driver is recent enough, this will
+automatically update the physical block size. If it is not recent enough,
+you will need to remove and rescan your device some other way for the
+new block size to be visible, if the size was changed with this command.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Send the format command for the specified nsid. This can be
+	used to override the default value for either character device
+	(unspecified) or the block device (result from NVME_IOCTL_ID).
+
+-l <lbaf>::
+--lbaf=<lbaf>::
+	LBA Format: This field specifies the LBA format to apply to the NVM
+	media. This corresponds to the LBA formats indicated in the
+	Identify Namespace command. Conflicts with --block-size argument.
+	Defaults to 0.
+
+-b <block size>::
+--block-size=<block size>::
+	Block Size: This field is used to specify the target block size to
+	format to. Potential lbaf values will be scanned and the lowest
+	numbered will be selected for the format operation. Conflicts with
+	--lbaf argument.
+
+-s <ses>::
+--ses=<ses>::
+	Secure Erase Settings: This field specifies whether a secure
+	erase should be performed as part of the format and the type of
+	the secure erase operation. The erase applies to all user data,
+	regardless of location (e.g., within an exposed LBA, within a
+	cache, within deallocated LBAs, etc). Defaults to 0.
++
+[]
+|=================
+|Value|Definition
+|0|No secure erase operation requested
+|1|User Data Erase: All user data shall be erased, contents of the user
+data after the erase is indeterminate (e.g., the user data may be zero
+filled, one filled, etc). The controller may perform a cryptographic
+erase when a User Data Erase is requested if all user data is encrypted.
+|2|Cryptographic Erase: All user data shall be erased
+cryptographically. This is accomplished by deleting the encryption key.
+|3–7|Reserved
+|=================
+ 
+-p <pil>::
+--pil=<pil>::
+	Protection Information Location: If set to ‘1’ and protection
+	information is enabled, then protection information is transferred
+	as the first eight bytes of metadata. If cleared to ‘0’ and
+	protection information is enabled, then protection information
+	is transferred as the last eight bytes of metadata. Defaults to 0.
+
+-i <pi>::
+--pi=<pi>::
+	Protection Information: This field specifies whether end-to-end
+	data protection is enabled and the type of protection
+	information. Defaults to 0.
++
+[]
+|=================
+|Value|Definition
+|0|Protection information is not enabled
+|1|Protection information is enabled, Type 1
+|2|Protection information is enabled, Type 2
+|3|Protection information is enabled, Type 3
+|4–7|Reserved
+|=================
+
+-m <ms>::
+--ms=<ms>::
+	Metadata Settings: This field is set to ‘1’ if the metadata
+	is transferred as part of an extended data LBA. This field is
+	cleared to ‘0’ if the metadata is transferred as part of a
+	separate buffer. The metadata may include protection information,
+	based on the Protection Information (PI) field. Defaults to 0.
+
+-r::
+--reset::
+	Issue a reset after successful format. Must use the character
+	device for this.
+
+--force::
+	Just send the command immediately without warning of the implications.
+
+-t <timeout>::
+--timeout=<timeout>::
+	Override default timeout value. In milliseconds.

+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, send an nvme Firmware Commit admin command and provides the results\&.
+.sp
+The Firmware Commit command is used to verify that a valid firmware image has been downloaded and to commit that revision to a specific firmware slot\&. The host may select the firmware image to commit on the next controller reset (CC\&.EN transitions from \(oq1\(cq to \(oq0\(cq, a PCI function level reset, and/or other Controller or NVM Subsystem Reset) as part of this command\&. The currently executing firmware revision may be determined from the Firmware Revision field of the Identify Controller data structure as indicated in the Firmware Slot Information log page\&.
+.sp
+No further action is automatically taken to reset the device, which is usually required to complete the activation process\&. If your kernel and driver are recent enough, you can commit the firmware by issuing a reset through Linux sysfs, for example:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ # echo 1 > /sys/class/nvme/nvme0/device/reset
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+If your kernel is not recent enough, you will need to remove and add the device some other way\&.

+
+DESCRIPTION
+-----------
+For the NVMe device given, send an nvme Firmware Commit admin command
+and provides the results.
+
+The Firmware Commit command is used to verify that a valid firmware
+image has been downloaded and to commit that revision to a specific
+firmware slot. The host may select the firmware image to commit on the
+next controller reset (CC.EN transitions from ‘1’ to ‘0’, a PCI
+function level reset, and/or other Controller or NVM Subsystem Reset)
+as part of this command. The currently executing firmware revision may
+be determined from the Firmware Revision field of the Identify Controller
+data structure as indicated in the Firmware Slot Information log page.
+
+No further action is automatically taken to reset the device, which is
+usually required to complete the activation process. If your kernel and
+driver are recent enough, you can commit the firmware by issuing a
+reset through Linux sysfs, for example:
+
+------------
+ # echo 1 > /sys/class/nvme/nvme0/device/reset
+------------
+
+If your kernel is not recent enough, you will need to remove and add
+the device some other way.

+The firmware image may be constructed of multiple pieces that are individually downloaded with separate Firmware Image Download commands\&. Each Firmware Image Download command includes a Dword Offset and Number of Dwords that specify a Dword range\&. The host software shall ensure that firmware pieces do not have Dword ranges that overlap\&. Firmware portions may be submitted out of order to the controller\&.
+.sp
+The new firmware image is not applied as part of the Firmware Image Download command\&. It is applied following a reset, where the image to apply and the firmware slot it should be committed to is specified with the Firmware Commit command (nvme fw\-commit <args>)\&.

+NAME
+----
+nvme-fw-download - Download all or a portion of an nvme firmware image.
+
+SYNOPSIS
+--------

+'nvme fw-download' <device> [--fw=<firmware-file> | -f <firmware-file>]
+		    [--xfer=<transfer-size> | -x <transfer-size>]
+		    [--offset=<offset> | -o <offset>]
+
+DESCRIPTION
+-----------
+The Firmware Image Download command is used to download all or a portion
+of the firmware image for a future update to the controller. The Firmware
+Image Download command may be submitted while other commands on the Admin
+Submission Queue or I/O Submission Queues are outstanding. The Firmware
+Image Download command copies the new firmware image (in whole or in part)
+to the controller.
+
+The firmware image may be constructed of multiple pieces that
+are individually downloaded with separate Firmware Image Download
+commands. Each Firmware Image Download command includes a Dword
+Offset and Number of Dwords that specify a Dword range. The host
+software shall ensure that firmware pieces do not have Dword ranges
+that overlap. Firmware portions may be submitted out of order to the
+controller.
+
+The new firmware image is not applied as part of the Firmware Image
+Download command. It is applied following a reset, where the image to
+apply and the firmware slot it should be committed to is specified with
+the Firmware Commit command (nvme fw-commit <args>).
+
+OPTIONS
+-------
+-f <firmware-file>::
+--fw=<firmware-file>::
+	Required argument. This specifies the path to the device's
+	firmware file on your system that will be read by the program
+	and sent to the device.
+
+-x <transfer-size>::
+--xfer=<transfer-size>::
+	This specifies the size to split each transfer. This is useful if
+	the device has a max transfer size requirement for firmware. It
+	defaults to 4k.
+
+-o <offset>::
+--offset=<offset>::
+	This specifies the starting offset in dwords. This is really only
+	useful if your firmware is split in multiple files; otherwise
+	the offset starts at zero and automatically adjusts based on the
+	'xfer' size given.

+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned f/w log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.

+nvme-fw-log - Send NVMe Firmware log page request, returns result and log
+
+SYNOPSIS
+--------
+[verse]
+'nvme fw-log' <device> [--raw-binary | -b]
+			[--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Retrieves the NVMe Firmware log page from an NVMe device and provides
+the returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned f/w log structure may be returned in one of
+several ways depending on the option flags; the structure may parsed by
+the program and printed in a readable format or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-b::
+--raw-binary::
+	Print the raw fw log buffer to stdout.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+
+EXAMPLES
+--------
+* Print the firmware log page in a human readable format:
++
+------------
+# nvme fw-log /dev/nvme0
+------------
++
+
+* Print the log firmware to a file:
++
+------------
+# nvme fw-log /dev/nvme0 --raw-binary > fw_log.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+Submits an NVMe Get Feature admin command and returns the applicable results\&. This may be the feature\(cqs value, or may also include a feature structure if the feature requires it (ex: LBA Range Type)\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned feature\(cqs structure (if applicable) may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format if it is a known structure, displayed in hex, or the raw buffer may be printed to stdout for another program to parse\&.

+NAME
+----
+nvme-get-feature - Gets an NVMe feature, returns applicable results
+
+SYNOPSIS
+--------
+[verse]
+'nvme get-feature' <device> [--namespace-id=<nsid> | -n <nsid>]
+			  [--feature-id=<fid> | -f <fid>] [--cdw11=<cdw11>]

+
+DESCRIPTION
+-----------
+Submits an NVMe Get Feature admin command and returns the applicable
+results. This may be the feature's value, or may also include a feature
+structure if the feature requires it (ex: LBA Range Type).
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned feature's structure (if applicable) may be
+returned in one of several ways depending on the option flags; the
+structure may parsed by the program and printed in a readable format
+if it is a known structure, displayed in hex, or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Retrieve the feature for the given nsid. This is optional and
+	most features do not use this value.
+
+-f <fid>::
+--feature-id=<fid>::
+	The feature id to send with the command. Value provided should
+	be in hex.
+
+-s <select>::
+--sel=<select>::
+	Select (SEL): This field specifies which value of the attributes
+	to return in the provided data:
++
+[]
+|==================
+|Select|Description
+|0|Current 
+|1|Default 
+|2|Saved
+|3|Supported capabilities
+|4–7|Reserved
+|==================
+
+-U <uuid-index>::
+--uuid-index=<uuid-index>::
+	UUID Index of the feature
+
+-l <data-len>::
+--data-len=<data-len>::
+	The data length for the buffer returned for this feature. Most
+	known features do not use this value. The exception is LBA
+	Range Type
+
+--cdw11=<cdw11>::
+	The value for command dword 11, if applicable.
+
+-b::
+--raw-binary::
+	Print the raw feature buffer to stdout if the feature returns
+	a structure.
+
+-H::
+--human-readable::
+	This option will parse and format many of the bit fields
+	into human-readable formats.
+
+EXAMPLES
+--------
+* Retrieves the feature for Number of Queues, or feature id 7:
++
+------------
+# nvme get-feature /dev/nvme0 -f 7
+------------
++
+
+* The following retrieves the feature for the LBA Range Type, which
+implicitly requires a buffer and will be printed to the screen in human
+readable format:
++
+------------
+# nvme get-feature /dev/nvme0 -f 3
+------------
++
+
+* Retrieves the feature for the some vendor specific feature and
+specifically requesting a buffer be allocate for this feature, which
+will be displayed to the user in as a hex dump:
++
+------------
+# nvme get-feature /dev/nvme0 -f 0xc0 -l 512
+------------
++
+Get feature with UUID index
+------------
+# nvme get-feature /dev/nvme0 -f 0xc0 -l 512 -U 0x1
+------------
+
+* The following retrieves the feature for the LBA Range Type, which
+implicitly requires a buffer and will be saved to a file in its raw
+format:
++
+------------
+# nvme get-feature /dev/nvme0 -f 3 --raw-binary > lba_range.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, send an nvme Get LBA Status admin command and provides the results\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned get lba data structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.
+.SH "OPTIONS"

+DESCRIPTION
+-----------
+For the NVMe device given, send an nvme Get LBA Status admin command
+and provides the results.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned get lba data structure may be returned in one of
+several ways depending on the option flags; the structure may parsed by
+the program and printed in a readable format or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Send the Get LBA Status command for the specified nsid. This can be
+	used to override the default value for either character device
+	(unspecified) or the block device (result from NVME_IOCTL_ID).
+
+-s <slba>::
+--start-lba=<slba>::
+	Starting LBA(SLBA) in 64-bit address of the first logical block addressed
+
+-m <max-dw>::
+--max-dw=<max-dw>::
+	Maximum Number of Dwords(MNDW) specifies maximum number of dwords to return
+
+-a <action-type>::

+	      [--log-len=<log-len> | -l <log-len>]
+	      [--aen=<aen> | -a <aen>]

+	      [--ot=<offset_type> | -O <offset_type>]
+
+DESCRIPTION
+-----------
+Retrieves an arbitrary NVMe log page from an NVMe device and provides
+the returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned log structure may be returned in one of several
+ways depending on the option flags; the structure may be displayed in
+hex by the program or the raw buffer may be printed to stdout for another
+program to parse.
+
+OPTIONS
+-------
+-l <log-len>::
+--log-len=<log-len>::
+	Allocates a buffer of <log-len> bytes size and requests this
+	many bytes be returned in the constructed NVMe command. This
+	param is mandatory.
+
+-i <log-id>::
+--log-id=<log-id>::
+	Sets the commands requested log-id to <log-id>. Defaults to 0.
+
+-a <aen>::
+--aen=<aen>::
+	Convenience field for extracting log information based on an
+	asynchronous event notification result. This will override log-id and
+	log-len, if set.
+
+-n <nsid>::
+--namespace-id=<nsid>::
+	Sets the command's nsid value to the given nsid. Defaults to
+	0xffffffff if not given. This option may not affect anything
+	depending on the log page, which may or may not be specific to
+	a namespace.
+
+-b::
+--raw-binary::
+	Print the raw log buffer to stdout.
+
+-o <offset>::
+--lpo=<offset>::
+	The log page offset specifies the location within a log page to start
+	returning data from. It's Dword-aligned and 64-bits.
+
+-s <field>::
+--lsp=<field>::
+	The log specified field of LID.
+
+-S <field>::
+--lsi=<field>::
+	The log specified field of Log Specific Identifier.
+
+-r::
+--rae::
+	Retain an Asynchronous Event.
+
+-y <command_set_identifier>::
+--csi=<command_set_identifier>::
+	This field specifies the identifier of command set.
+	if not issued, NVM Command Set will be selected.
+
+-O::
+--ot::
+	This field specifies the offset type. If set to false, the
+	Log Page Offset Lower field and the Log Page Offset Upper
+	field specify the byte offset into the log page to be returned.
+	If set to true, the Log Page Offset Lower field and the Log
+	Page Offset Upper field specify the index into the list of
+	data structures in the log page to be returned.
+	The default is byte offset. If the option is specified
+	the index mode is used.
+
+EXAMPLES
+--------
+* Get 512 bytes from log page 2
++
+------------
+# nvme get-log /dev/nvme0 --log-id=2 --log-len=512
+------------
++
+The above example will get log page 2 (SMART), and request 512
+bytes. On success, the returned log will be dumped in hex and not
+interpreted by the program.
+
+* Have the program return the raw log page in binary:
++
+------------
+# nvme get-log /dev/nvme0 -log-id=2 --log-len=512 --raw-binary > log_page_2.raw
+# nvme get-log /dev/nvme0 -i 2 -l 512 -b > log_page_2.raw
+------------
++
+It is not a good idea to not redirect stdout when using this mode.

+nvme-huawei-id-ctrl - Send NVMe Identify Controller, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme huawei id-ctrl' <device> [-v | --vendor-specific] [-b | --raw-binary]
+			[-o <fmt> | --output-format=<fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify controller command and
+provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+This will only work on Huawei devices supporting this feature.
+Results for any other device are undefined.
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+If having the program decode the output for readability, this version
+will decode Huawei vendor unique portions of the structure.
+
+OPTIONS
+-------
+-b::
+--raw-binary::
+	Print the raw buffer to stdout. Structure is not parsed by
+	program. This overrides the vendor specific and human readable options.
+
+-v::
+--vendor-specific::
+	In addition to parsing known fields, this option will dump
+	the vendor specific region of the structure in hex with ascii
+	interpretation.
+
+-H::
+--human-readable::
+	This option will parse and format many of the bit fields
+	into human-readable formats.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:

+.fi
+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, sends an identify controller command and provides the result and returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.
+.SH "OPTIONS"
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw buffer to stdout\&. Structure is not parsed by program\&. This overrides the vendor specific and human readable options\&.
+.RE
+.PP
+\-v, \-\-vendor\-specific
+.RS 4
+In addition to parsing known fields, this option will dump the vendor specific region of the structure in hex with ascii interpretation\&.
+.RE
+.PP
+\-H, \-\-human\-readable
+.RS 4
+This option will parse and format many of the bit fields into human\-readable formats\&.
+.RE
+.PP
+\-o <format>, \-\-output\-format=<format>
+.RS 4
+Set the reporting format to
+\fInormal\fR,
+\fIjson\fR, or
+\fIbinary\fR\&. Only one output format can be used at a time\&.

+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+Has the program interpret the returned buffer and display the known fields in a human readable format:

+.nf
+# nvme id\-ctrl /dev/nvme0 \-\-vendor\-specific
+# nvme id\-ctrl /dev/nvme0 \-v
+.fi
+.if n \{\

+.\}
+.sp
+The above will dump the
+\fIvs\fR
+buffer in hex since it doesn\(cqt know how to interpret it\&.

+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1

+# nvme id\-ctrl /dev/nvme0 \-b > id_ctrl\&.raw
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+It is probably a bad idea to not redirect stdout when using this mode\&.

+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3

+Alternatively you may want to send the data to another program that can parse the raw buffer\&.

+# nvme id\-ctrl /dev/nvme0 \-\-raw\-binary | nvme_parse_id_ctrl
+.fi
+.if n \{\

+.sp
+The parse program in the above example can be a program that shows the structure in a way you like\&. The following program is such an example that will parse it and can accept the output through a pipe,

+nvme-id-ctrl - Send NVMe Identify Controller, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme id-ctrl' <device> [-v | --vendor-specific] [-b | --raw-binary]
+			[-o <fmt> | --output-format=<fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify controller command and
+provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+OPTIONS
+-------
+-b::
+--raw-binary::
+	Print the raw buffer to stdout. Structure is not parsed by
+	program. This overrides the vendor specific and human readable options.
+
+-v::
+--vendor-specific::
+	In addition to parsing known fields, this option will dump
+	the vendor specific region of the structure in hex with ascii
+	interpretation.
+
+-H::
+--human-readable::
+	This option will parse and format many of the bit fields
+	into human-readable formats.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:
++
+------------
+# nvme id-ctrl /dev/nvme0
+------------
++
+
+* In addition to showing the known fields, has the program to display
+the vendor unique field:
++
+------------
+# nvme id-ctrl /dev/nvme0 --vendor-specific
+# nvme id-ctrl /dev/nvme0 -v
+------------
++
+The above will dump the 'vs' buffer in hex since it doesn't know how to
+interpret it.
+
+* Have the program return the raw structure in binary:
++
+------------
+# nvme id-ctrl /dev/nvme0 --raw-binary > id_ctrl.raw
+# nvme id-ctrl /dev/nvme0 -b > id_ctrl.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.
+
+* Alternatively you may want to send the data to another program that
+can parse the raw buffer.
++
+------------
+# nvme id-ctrl /dev/nvme0 --raw-binary | nvme_parse_id_ctrl
+------------
++
+The parse program in the above example can be a program that shows the
+structure in a way you like. The following program is such an example
+that will parse it and can accept the output through a pipe, `'|'`,
+as shown in the above example, or you can `'cat'` a saved output buffer to it.

+nvme-id-ns-lba-format(1)
+========================
+
+NAME
+----
+nvme-id-ns-lba-format - Send NVMe Identify Namespace for the specified LBA Format index, display structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme id-ns' <device> [--uuid-index=<uuid-index> | -U <uuid_index>]
+		    [--lba-format-index=<lba_format_index> | -i <lba_format_index>]
+			[-v | --verbose]
+			[--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify namespace for
+the specified LBA Format index command and provides the result
+that is include capability field only and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+OPTIONS
+-------
+-U <uuid-index>::
+--uuid-index=<uuid-index>::
+	UUID Index of the feature
+	
+-i <lba_format_index>::
+--lba-format-index=<lba_format_index>::
+	This field specifies the index into the LBA Format list identifying
+	the LBA Format capabilities that are to be returned
+
+-v::
+--verbose::
+	Increase the information detail in the output.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:
++
+------------
+# nvme id-ns-lba-format /dev/nvme0n1 -i 0
+------------
++
+* Have the program return the raw structure in binary:
++
+------------
+# nvme id-ns-lba-format /dev/nvme0n1 -i 0 -o binary > id_ns.raw
+# nvme id-ns-lba-format /dev/nvme0n1 -i 0 --output-format=binary > id_ns.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.
+
+* Alternatively you may want to send the data to another program that
+can parse the raw buffer.
++
+------------
+# nvme id-ns-lba-format /dev/nvme0n1 -i 0 --raw-binary | nvme_parse_id_ns
+------------
++
+The parse program in the above example can be a program that shows the
+structure in a way you like. The following program is such an example
+that will parse it and can accept the output through a pipe, `'|'`,
+as shown in the above example, or you can `'cat'` a saved output buffer
+to it.

+/* File: nvme_parse_id_ns_lba_format.c */

+#include <linux/nvme.h>
+#include <stdio.h>
+#include <unistd.h>

+int main(int argc, char **argv)

+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, sends an identify namespace command and provides the result and returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&. If the character device is given, the \*(Aq\-\-namespace\-id\*(Aq option is mandatory, otherwise it will use the ns\-id of the namespace for the block device you opened\&. For block devices, the ns\-id used can be overridden with the same option\&.
+.sp
+On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.
+.SH "OPTIONS"
+.PP
+\-n <nsid>, \-\-namespace\-id=<nsid>
+.RS 4
+Retrieve the identify namespace structure for the given nsid\&. This is required for the character devices, or overrides the block nsid if given\&. If the controller supports namespace management capability and 0xFFFFFFFF is given, then the controller returns the identify namespace structure that specifies common capabilities across namespaces for the controller\&.
+.RE
+.PP
+\-\-force
+.RS 4
+Request controller return the identify namespace structure even if the namespace is not attached to the controller\&. This is valid only for controllers at or newer than revision 1\&.2\&. Controllers at revision lower than this may interpret the command incorrectly\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw buffer to stdout\&. Structure is not parsed by program\&. This overrides the vendor specific and human readable options\&.
+.RE
+.PP
+\-v, \-\-vendor\-specific
+.RS 4
+In addition to parsing known fields, this option will dump the vendor specific region of the structure in hex with ascii interpretation\&.
+.RE
+.PP
+\-H, \-\-human\-readable
+.RS 4
+This option will parse and format many of the bit fields into human\-readable formats\&.
+.RE

+nvme-id-ns - Send NVMe Identify Namespace, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme id-ns' <device> [-v | --vendor-specific] [-b | --raw-binary]
+		    [--namespace-id=<nsid> | -n <nsid>] [--force]
+		    [--human-readable | -H]
+		    [--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify namespace command and
+provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+If the character device is given, the `'--namespace-id'` option is
+mandatory, otherwise it will use the ns-id of the namespace for the block
+device you opened. For block devices, the ns-id used can be overridden
+with the same option.
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Retrieve the identify namespace structure for the given nsid. This
+	is required for the character devices, or overrides the block nsid
+	if given. If the controller supports namespace management capability
+	and 0xFFFFFFFF is given, then the controller returns the identify
+	namespace structure that specifies common capabilities across
+	namespaces for the controller.
+
+--force::
+	Request controller return the identify namespace structure even
+	if the namespace is not attached to the controller. This is valid
+	only for controllers at or newer than revision 1.2. Controllers
+	at revision lower than this may interpret the command incorrectly.
+
+-b::
+--raw-binary::
+	Print the raw buffer to stdout. Structure is not parsed by
+	program. This overrides the vendor specific and human readable options.
+
+-v::
+--vendor-specific::
+	In addition to parsing known fields, this option will dump
+	the vendor specific region of the structure in hex with ascii
+	interpretation.
+
+-H::
+--human-readable::
+	This option will parse and format many of the bit fields
+	into human-readable formats.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:
++
+------------
+# nvme id-ns /dev/nvme0n1
+------------
++
+
+* If using the character device or overriding namespace id:
++
+------------
+# nvme id-ns /dev/nvme0 -n 1
+# nvme id-ns /dev/nvme0n1 -n 1

+The parse program in the above example can be a program that shows the

+.sp
+For the NVMe device given, sends an identify NVM set list command and provides the result and returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.
+.SH "OPTIONS"
+.PP
+\-i <id>, \-\-nvmset_id=<id>

+=================
+
+NAME
+----
+nvme-id-nvmset - Send NVMe Identify NVM Set List, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme id-nvmset' <device> [-i <id> | --nvmset_id=<id> ]
+			[-o <fmt> | --output-format=<fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify NVM set list command and
+provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+OPTIONS
+-------
+-i <id>::
+--nvmset_id=<id>::
+	This field specifies the identifier of the NVM Set.  If given, NVM set
+	identifier whose entry is to be in result data will be greater than or
+	equal to this value.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:
++
+------------
+# nvme id-nvmset /dev/nvme0
+------------
++
+
+* Have the program return the raw structure in binary:
++
+------------
+# nvme id-nvmset /dev/nvme0 --output-format=binary > id_nvmset.raw
+# nvme id-nvmset /dev/nvme0 -o binary > id_nvmset.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.
+
+* Alternatively you may want to send the data to another program that
+can parse the raw buffer.
++
+------------
+# nvme id-nvmset /dev/nvme0 -o binary | nvme_parse_id_nvmset
+------------
++
+The parse program in the above example can be a program that shows the
+structure in a way you like. The following program is such an example
+that will parse it and can accept the output through a pipe, `'|'`,
+as shown in the above example, or you can `'cat'` a saved output buffer to it.

+nvme-intel-id-ctrl - Send NVMe Identify Controller, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme intel id-ctrl' <device> [-v | --vendor-specific] [-b | --raw-binary]
+			[-o <fmt> | --output-format=<fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify controller command and
+provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+If having the program decode the output for readability, this version
+will decode Intel vendor unique portions of the structure.
+
+OPTIONS
+-------
+-b::
+--raw-binary::
+	Print the raw buffer to stdout. Structure is not parsed by
+	program. This overrides the vendor specific and human readable options.
+
+-v::
+--vendor-specific::
+	In addition to parsing known fields, this option will dump
+	the vendor specific region of the structure in hex with ascii
+	interpretation.
+
+-H::
+--human-readable::
+	This option will parse and format many of the bit fields
+	into human-readable formats.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:

+
+The <device> parameter is mandatory and may be either the NVMe
+character device (ex: /dev/nvme0), or a namespace block device (ex:
+/dev/nvme0n1). If using the character device, the namespace id parameter
+is mandatory.
+
+This will only work on Intel devices supporting this feature which
+includes (but not limited to) all the Intel DC P3xxx family of
+controllers. Results for any other device are undefined.

+simply the marketing name used to identify what kind of device it is.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the structure may be returned in one of several ways depending

+
+DESCRIPTION
+-----------
+Retrieves the NVMe Intel Additional SMART log page from the device and
+provides the returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned smart log structure may be returned in one of
+several ways depending on the option flags; the structure may parsed by
+the program and printed in a readable format or the raw buffer may be
+printed to stdout for another program to parse.

+
+DESCRIPTION
+-----------
+Retrieves the NVMe Intel Additional SMART log page from the device and

+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned smart log structure may be returned in one of
+several ways depending on the option flags; the structure may parsed by
+the program and printed in a readable format or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------

+DESCRIPTION
+-----------
+For the NVMe device given, issues the I/O Management Send command with the
+requested management operation (mo) and management operation specific parameter
+(mos). This is the generic interface provided for forward compatibility as new
+operations are added that this program isn't aware of at the time of its
+development. As such, this is a generic command that does not provide any
+convenience parameters to produce the binary payload.
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+	Use the provided namespace id for the command. If not provided, the
+	namespace id of the block device will be used. If the command is issued
+	to a non-block device, the parameter is required.
+
+-d <FILE>::
+--data=<FILE>::
+	File to read payload from. If unspecified, data will be read from the
+	standard input stream.
+
+-l <NUM>::
+--data-len=<NUM>::
+	Payload data buffer length
+
+-m <NUM>::
+--mo <NUM>::
+	Management Operation to perform.
+
+-s <NUM>::
+--mos=<NUM>::
+	Management Operation Specific parameter.

+.SH "DESCRIPTION"
+.sp
+Submits an arbitrary NVMe IO command and returns the applicable results\&. This may be the simply the command\(cqs result and status, or may also include a buffer if the command returns one\&. This command does no interpretation of the opcodes or options\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned structure (if applicable) may be returned in one of several ways depending on the option flags; the structure may printed by the program as a hex dump, or may be returned as a raw buffer printed to stdout for another program to parse\&.
+.SH "OPTIONS"
+.PP
+\-o <opcode>, \-\-opcode=<opcode>
+.RS 4
+The NVMe opcode to send to the device in the command
+.RE
+.PP
+\-f <flags>, \-\-flags=<flags>
+.RS 4
+The NVMe command flags to send to the device in the command
+.RE
+.PP
+\-R <rsvd>, \-\-rsvd=<rsvd>
+.RS 4
+The value for the reserved field in the command\&.
+.RE
+.PP
+\-n <nsid>, \-\-namespace\-id=<nsid>
+.RS 4
+The value for the ns\-id in the command\&. Defaults to
+\fI0\fR\&.
+.RE
+.PP
+\-\-cdw[2\-3,10\-15]=<cdw>
+.RS 4
+Specifies the command dword value for that specified entry in the command
+.RE
+.PP
+\-r, \-\-read, \-w, \-\-write
+.RS 4
+Used for the data\-direction for the command and required for commands sending/receiving data\&. Don\(cqt use both read and write at the same time\&.
+.RE
+.PP
+\-i <file>, \-\-input\-file=<file>
+.RS 4
+If the command is a data\-out (write) command, use this file to fill the buffer sent to the device\&. If no file is given, assumed to use STDIN\&. If the command is a data\-in (read) command, the data returned from the device will be saved here\&.
+.RE
+.PP
+\-M <file>, \-\-metadata=<file>
+.RS 4
+If the command is a data\-out (write) command, use this file to fill the metadata buffer sent to the device\&. If no file is given, assumed to use STDIN\&. If the command is a data\-in (read) command, the metadata returned from the device will be saved here\&.
+.RE
+.PP
+\-l <data\-len>, \-\-data\-len=<data\-len>
+.RS 4
+The data length for the buffer used for this command\&.
+.RE
+.PP
+\-m <data\-len>, \-\-metadata\-len=<data\-len>
+.RS 4
+The metadata length for the buffer used for this command\&.
+.RE
+.PP
+\-s, \-\-show\-cmd
+.RS 4
+Print out the command to be sent\&.
+.RE
+.PP
+\-d, \-\-dry\-run
+.RS 4
+Do not actually send the command\&. If want to use \-\-dry\-run option, \-\-show\-cmd option
+\fImust\fR
+be set\&. Otherwise \-\-dry\-run option will be
+\fIignored\fR\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw returned buffer to stdout if the command returns data or a structure\&.
+.RE
+.PP
+\-p <prefill>, \-\-prefill <prefill>
+.RS 4
+Prefill the buffer with a predetermined byte value\&. Defaults to 0\&. This may be useful if the data you are writing is shorter than the required buffer, and you need to pad it with a known value\&. It may also be useful if you need to confirm if a device is overwriting a buffer on a data\-in command\&.
+.RE
+.PP
+\-T, \-\-latency
+.RS 4
+Print out the latency the IOCTL took (in us)\&.

+
+DESCRIPTION
+-----------
+Submits an arbitrary NVMe IO command and returns the applicable
+results. This may be the simply the command's result and status, or may
+also include a buffer if the command returns one. This command does no
+interpretation of the opcodes or options.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned structure (if applicable) may be returned in
+one of several ways depending on the option flags; the structure may
+printed by the program as a hex dump, or may be returned as a raw buffer
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-o <opcode>::
+--opcode=<opcode>::
+	The NVMe opcode to send to the device in the command
+
+-f <flags>::
+--flags=<flags>::
+	The NVMe command flags to send to the device in the command
+
+-R <rsvd>::
+--rsvd=<rsvd>::
+	The value for the reserved field in the command.
+
+-n <nsid>::
+--namespace-id=<nsid>::
+	The value for the ns-id in the command. Defaults to '0'.
+
+--cdw[2-3,10-15]=<cdw>::
+	Specifies the command dword value for that specified entry in
+	the command
+
+-r::
+--read::
+-w::
+--write::
+	Used for the data-direction for the command and required for
+	commands sending/receiving data. Don't use both read and write
+	at the same time.
+
+-i <file>::
+--input-file=<file>::
+	If the command is a data-out (write) command, use this file
+	to fill the buffer sent to the device. If no file is given, assumed to
+	use STDIN. If the command is a data-in (read) command, the data
+	returned from the device will be saved here.
+
+-M <file>::
+--metadata=<file>::
+	If the command is a data-out (write) command, use this file
+	to fill the metadata buffer sent to the device. If no file is given,
+	assumed to use STDIN. If the command is a data-in (read) command, the
+	metadata returned from the device will be saved here.
+
+-l <data-len>::
+--data-len=<data-len>::
+	The data length for the buffer used for this command.
+
+-m <data-len>::
+--metadata-len=<data-len>::
+	The metadata length for the buffer used for this command.
+
+-s::
+--show-cmd::
+	Print out the command to be sent.
+
+-d::
+--dry-run::
+	Do not actually send the command. If want to use --dry-run option,
+	--show-cmd option _must_ be set. Otherwise --dry-run option will be
+	_ignored_.
+
+-b::
+--raw-binary::
+	Print the raw returned buffer to stdout if the command returns
+	data or a structure.
+
+-p <prefill>::
+--prefill <prefill>::
+	Prefill the buffer with a predetermined byte value. Defaults to 0.
+	This may be useful if the data you are writing is shorter
+	than the required buffer, and you need to pad it with a known
+	value. It may also be useful if you need to confirm if a device
+	is overwriting a buffer on a data-in command.
+
+-T::
+--latency::
+	Print out the latency the IOCTL took (in us).
+

+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+The starting controller in the list always begins with 0 unless the
+`\*(Aq\-\-cntid\*(Aq` option is given to override\&.
+
+On success, the controller array is printed for each index and controller
+identifier\&.

+.sp
+This command prints NAND information (Total bytes written, Bad block count and Erase failures etc) for the given micron device if its of 2200 model controller\&. For OCP complaint controllers this command print extended SMART health data along with NAND information (if available)
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+The \fI\-f\fR option controls the displayed output data format based on the option value\&. If the option value is \fIjson\fR (which is enabled by default), output data is printed in JSON format\&. If option value is \fInormal\fR the output is displayed in non\-JSON format\&.
+.sp
+This will only work on Micron devices devices of model numbers 54XX and OCP complaint controllers\&. Support for new devices may be added subsequently\&.

+'nvme micron vs-smart-add-log' <device>  -f <json|normal>
+
+DESCRIPTION
+-----------
+This command prints NAND information (Total bytes written, Bad block count and 
+Erase failures etc) for the given micron device if its of 2200 model controller.
+For OCP complaint controllers this command print extended SMART health data
+along with NAND information (if available)
+
+The <device> parameter is mandatory and may be either the NVMe
+character device (ex: /dev/nvme0), or a namespace block device (ex:
+/dev/nvme0n1). 
+
+The '-f' option controls the displayed output data format based on the option
+value. If the option value is 'json' (which is enabled by default), output data
+is printed in JSON format. If option value is 'normal' the output is displayed
+in non-JSON format.
+
+This will only work on Micron devices devices of model numbers 54XX and OCP
+complaint controllers. Support for new devices may be added subsequently.

+.fi
+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, sends an identify for a list of namespace identification descriptor structures command and provides the result and returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&. If the character device is given, the \*(Aq\-\-namespace\-id\*(Aq option is mandatory, otherwise it will use the ns\-id of the namespace for the block device you opened\&. For block devices, the ns\-id used can be overridden with the same option\&.
+.sp
+On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.
+.SH "OPTIONS"
+.PP
+\-n <nsid>, \-\-namespace\-id=<nsid>
+.RS 4
+Retrieve the identify namespace identification descriptor structure for the given nsid\&. This is required for the character devices, or overrides the block nsid if given\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw buffer to stdout\&. Structure is not parsed by program\&.
+.RE
+.PP
+\-o <format>, \-\-output\-format=<format>
+.RS 4
+Set the reporting format to
+\fInormal\fR,
+\fIjson\fR, or
+\fIbinary\fR\&. Only one output format can be used at a time\&.
+.RE
+.SH "EXAMPLES"
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\

+If using the character device or overriding namespace #2:
+.sp

+.ie n \{\

+================

+NAME
+----
+nvme-ns-descs - Send NVMe Identify for a list of Namespace Identification
+		Descriptor structure, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme ns-descs' <device> [--namespace-id=<nsid> | -n <nsid>]
+			[--raw-binary | -b]
+			[--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify for a list of namespace
+identification descriptor structures command and provides the result and
+returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+If the character device is given, the `'--namespace-id'` option is
+mandatory, otherwise it will use the ns-id of the namespace for the block
+device you opened. For block devices, the ns-id used can be overridden
+with the same option.
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Retrieve the identify namespace identification descriptor structure
+	for the given nsid. This is required for the character devices, or
+	overrides the block nsid if given.
+
+-b::
+--raw-binary::
+	Print the raw buffer to stdout. Structure is not parsed by
+	program.
+
+-o <format>::
+--output-format=<format>::
+	Set the reporting format to 'normal', 'json', or 'binary'.
+	Only one output format can be used at a time.
+
+
+EXAMPLES
+--------
+* If using the character device or overriding namespace #2:
++
+------------
+# nvme ns-descs /dev/nvme0 -n 1
+# nvme ns-descs /dev/nvme0n1 -n 2
+# nvme ns-descs /dev/nvme0 --namespace-id=1
+------------
++
+
+* Have the program return the raw structure in binary:
++
+------------
+# nvme ns-descs /dev/nvme0n1 --raw-binary > ns_descs.raw
+# nvme ns-descs /dev/nvme0n1 -b > ns_descs.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.

+	This field specifies the index into the LBA Format list identifying
+	the LBA Format capabilities that are to be returned
+
+-v::
+--verbose::
+	Increase the information detail in the output.

+=================
+
+NAME
+----
+nvme-nvm-id-ns - Send NVMe Identify NVM Command Set specific Namespace data structure, display structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme nvm-id-ns' <device> [--uuid-index=<uuid-index> | -U <uuid_index>]
+			[--namespace-id=<NUM> | -n <NUM>]
+			[-v | --verbose]
+			[--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Identify NVM Command Set specific Namespace data structure for the specified
+NSID for the NVM Command Set specified in the CSI field.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+	Use the provided namespace id for the command. If not provided, the
+	namespace id of the block device will be used. If the command is issued
+	to a non-block device, the parameter is required.
+
+-U <uuid-index>::
+--uuid-index=<uuid-index>::
+	UUID Index of the feature
+
+-v::
+--verbose::
+	Increase the information detail in the output.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:
++
+------------
+# nvme nvm-id-ns /dev/nvme0n1
+------------
++
+
+* If using the character device or overriding namespace id:
++
+------------
+# nvme nvm-id-ns /dev/nvme0 -n 1
+# nvme nvm-id-ns /dev/nvme0n1 -n 1
+# nvme nvm-id-ns /dev/nvme0 --namespace-id=1
+------------
++
+* Have the program return the raw structure in binary:
++
+------------
+# nvme nvm-id-ns /dev/nvme0n1 -o binary > id_ns.raw
+# nvme nvm-id-ns /dev/nvme0n1 --output-format=binary > id_ns.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.
+
+* Alternatively you may want to send the data to another program that
+can parse the raw buffer.

+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1)\&.
+.sp
+This command with no option added, will try to automatically detect the parameters of the command\&. This will work successfully or fail gracefully for devices supporting UUID for Vendor Specific Information (NVMe 1\&.4 or later, OCP 2\&.0 requires NVMe 1\&.4b)\&. For devices that do not support OCP 2\&.0 the command will fail gracefully, unless the \-\-no\-uuid option is provided\&.
+.sp
+For OCP 1\&.0 devices (before NVMe 1\&.4) the \-\-no\-uuid option is required\&. When \-\-no\-uuid option is provided, results for devices before NVMe 1\&.4 without OCP support are undefined\&.

+.fi
+.SH "DESCRIPTION"
+.sp
+Retrieves the NVMe persistent event log page from an NVMe device and provides the returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned persistent event log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.
+.SH "OPTIONS"
+.PP
+\-a <action>, \-\-action=<action>
+.RS 4
+While try to retrieve this log action the controller shall take during processing this persistent log page command\&. This mandatory field, based on the value issued it may Read Log Data, Establish Context and Read Log Data or Release Context can occur\&. For More details see NVM Express 1\&.4 Spec\&. Section 5\&.14\&.1\&.13 Persistent Event Log (Log Identifier 0Dh)
+.RE
+.PP
+\-l <log\-len>, \-\-log\-len=<log\-len>
+.RS 4
+Allocates a buffer of <log\-len> bytes size and requests this many bytes be returned in the constructed NVMe command\&. This param is mandatory\&. If <log\-len> given is 0 and action is 0, it will read the Total Log Length(TLL) of the page\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw persistent event log buffer to stdout\&.
+.RE
+.PP
+\-o <format>, \-\-output\-format=<format>
+.RS 4
+Set the reporting format to
+\fInormal\fR,
+\fIjson\fR, or
+\fIbinary\fR\&. Only one output format can be used at a time\&.

+
+DESCRIPTION
+-----------
+Retrieves the NVMe persistent event log page from an NVMe device
+and provides the returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned persistent event log structure may be returned
+in one of several ways depending on the option flags; the structure may
+parsed by the program and printed in a readable format or the raw buffer
+may be printed to stdout for another program to parse.
+
+OPTIONS

+-a <action>::
+--action=<action>::
+    While try to retrieve this log action the controller shall take
+    during processing this persistent log page command. This mandatory
+    field, based on the value issued it may Read Log Data, Establish

+
+-o <format>::

+    Set the reporting format to 'normal', 'json', or 'binary'.
+    Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Print the persistent event log page in a human readable format:
++
+------------
+# nvme persistent-event-log /dev/nvme0

++
+
+* Print the raw persistent event log to a file:

+.SH "DESCRIPTION"
+.sp
+The Reservation Report command returns a Reservation Status data structure to host memory that describes the registration and reservation status of a namespace\&.
+.sp
+The size of the Reservation Status data structure is a function of the number of controllers in the NVM Subsystem that are associated with hosts that are registrants of the namespace (i\&.e\&., there is a Registered Controller data structure for each such controller)\&.
+.SH "OPTIONS"
+.PP
+\-n <nsid>, \-\-namespace\-id=<nsid>
+.RS 4
+Retrieve the reservation report structure for the given nsid\&. This is required for the character devices, or overrides the block nsid if given\&.
+.RE
+.PP
+\-d <num\-dwords>, \-\-numd=<num\-dwords>
+.RS 4
+Specify the number of Dwords of the Reservation Status structure to transfer\&. Defaults to 4k\&.
+.RE
+.PP
+\-e, \-\-eds
+.RS 4
+Request extended Data Structure: If this bit is set to a
+\fI1\fR, then the controller returns the Extended Data Structure\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw buffer to stdout\&. Structure is not parsed by program\&.
+.RE
+.PP
+\-o <format>, \-\-output\-format=<format>
+.RS 4
+Set the reporting format to
+\fInormal\fR,
+\fIjson\fR, or
+\fIbinary\fR\&. Only one output format can be used at a time\&.
+.RE
+.SH "EXAMPLES"
+.sp
+No examples yet\&.

+DESCRIPTION
+-----------
+The Reservation Report command returns a Reservation Status data structure
+to host memory that describes the registration and reservation status
+of a namespace.
+
+The size of the Reservation Status data structure is a function of the
+number of controllers in the NVM Subsystem that are associated with
+hosts that are registrants of the namespace (i.e., there is a Registered
+Controller data structure for each such controller).
+

+NAME

+nvme-rpmb - Send RPMB commands to an NVMe device
+
+SYNOPSIS
+--------
+[verse]
+'nvme rpmb' <device> [--cmd=<command> | -c <command>]
+		    [--msgfile=<data-file> | -f <data-file>]
+		    [--keyfile=<key-file> | -g <key-file>]
+		    [--key=<key> | -k <key>]
+		    [--msg=<data> | -d <data>]
+		    [--address=<offset> | -o <offset>]
+		    [--blocks=<512 byte sectors> | -b <sectors> ]
+		    [--target=<target-id> | -t <id> ]
+
+DESCRIPTION
+-----------
+For the NVMe device given, send an nvme rpmb command and provide the results.
+
+The <device> parameter is mandatory and NVMe character device (ex: /dev/nvme0)
+must be specified. If the given device supports RPMB targets, command given
+with --cmd or -c option shall be sent to the controller. If given NVMe device
+doesn't support RPMB targets, a message indicating the same shall be printed
+along with controller register values related RPMB.
+
+OPTIONS
+-------
+-c <command>::
+--cmd=<command>::
+	RPMB command to be sent to the device. It can be one of the following
+
+	info          - print information regarding supported RPMB targets and
+			access and total sizes. No further arguments are required
+
+	program-key   - program 'key' specified with -k option or key read from
+			file specified with --keyfile option to the specified
+			RPMB target given with --target or -t options. As per 
+			spec, this is one time action which can't be undone.
+
+	read-counter  - Read 'write counter' of specified RPMB target. The
+			counter value read is printed onto STDOUT
+
+	read-config   - Read 512 bytes of device configuration block data of
+			specified RPMB target of the NVMe device. The data read
+			is written to input file specified with --msgfile or -f
+			option.
+	write-config  - Write 512 byes of device configuration block data
+			from file specified by --msgfile or -f options to the
+			RPMB target specified with --target or -t options.
+
+	read-data     - Supports authenticated data reading from specified
+			RPMB target (--target or -t option) at given offset
+			specified with --address or -o option, using key
+			specified using --keyfile or -k options. --blocks or
+			-o option should be given to read the amount of data
+			to be read in 512 byte blocks.
+
+	write-data    - Supports authenticated data writing to specified RPMB
+			target (--target or -t option) at given offset
+			specified with --address or -o option, using key
+			specified using --keyfile or -k options. --blocks or
+			-o option should be given to indicate amount of data
+			to be written in 512 byte blocks.
+
+	For data transfer (read/write) commands, if the specified size is not
+	within the total size supported by a target, the request is failed
+	nvme-rpmb without sending it to device. RPMB target 0 is used as the
+	default target if --target or -t is not specified. 0x0 is used as the
+	default address if no -address or -o option is specified, 
+	
+-t <target>::
+--target=<target>::
+	RPMB target id. This should be one of the supported RPMB targets as
+	reported by 'info' command. If nothing is given, default of 0 is used
+	as RPMB target.
+
+-k <key>::
+--key=<key>::
+-g <key-file>::
+--keyfile=<key-file>::
+	Authentication key to be used for read/write commands. This should have
+	been already programmed by 'program-key' command for given target. Key
+	can be specified on command line using --key or -k options. Key can
+	also be specified using file argument specified with --keyfile or -g 
+	options.
+
+-f <data-file>::
+--msgfile=<data-file>::
+	Name of the file to be used for data transfer commands (read or write).
+	For read command, if an existing file is specified, it will be appended.
+
+-d <data>::
+--msg=<data>::
+	These options provide the data on the command line itself. 
+-o <offset>::
+--address=<offset>::
+	The address (in 512 byte sector offset from 0) to be used for data 
+	transfer commands (read or write) for a specified RPMB target.
+-b::
+--blocks=<sectors>::
+	The size in 512 byte sectors to be used for data transfer commands
+	(read or write) for a specified RPMB target.
+

+[verse]
+'nvme seagate vs-smart-add-log <device> [OPTIONS]'
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends the Seagate vendor log
+request and either saves the result to a file or dumps the content to stdout.
+
+The <device> parameter is mandatory and may be either the NVMe
+character device (ex: /dev/nvme0), or a namespace block device (ex:
+/dev/nvme0n1).
+
+The log contents may be associated with the controller, in which case the namespace parameter is ignored.
+
+Two logs exist, page 0xC4 (Extended SMART log page) and page 0xCF (DRAM Supercap SMART log page)
+
+This command will only work on Seagate devices supporting this feature.  Not
+all commands work across all product families.

+.SH "DESCRIPTION"
+.sp
+The Security Receive command transfers the status and data result of one or more Security Send commands that were previously submitted to the controller\&.
+.sp
+The association between a Security Receive command and previous Security Send commands is dependent on the Security Protocol\&. The format of the data to be transferred is dependent on the Security Protocol\&. Refer to SPC\-4 for Security Protocol details\&.
+.sp
+Each Security Receive command returns the appropriate data corresponding to a Security Send command as defined by the rules of the Security Protocol\&. The Security Receive command data may not be retained if there is a loss of communication between the controller and host, or if a controller reset occurs\&.

+nvme-security-recv - Security Recv command
+
+SYNOPSIS
+--------
+[verse]
+'nvme security-recv' <device> [--size=<size> | -x <size>]
+		    [--secp=<security-protocol> | -p <security-protocol>]
+		    [--spsp=<protocol-specific> | -s <protocol-specific>]
+		    [--nssf=<nvme-specific> | -N <nvme-specific>]

+		    [--raw-binary | -b]
+
+DESCRIPTION
+-----------
+The Security Receive command transfers the status and data result of
+one or more Security Send commands that were previously submitted to
+the controller.
+
+The association between a Security Receive command and previous Security
+Send commands is dependent on the Security Protocol. The format of the
+data to be transferred is dependent on the Security Protocol. Refer to
+SPC-4 for Security Protocol details.
+
+Each Security Receive command returns the appropriate data corresponding
+to a Security Send command as defined by the rules of the Security
+Protocol. The Security Receive command data may not be retained if there
+is a loss of communication between the controller and host, or if a
+controller reset occurs.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Target a specific namespace for this security command.
+
+-N <nssf>::
+--nssf=<nssf>::
+	NVMe Security Specific field. If using security protocol EAh
+	assigned for NVMe use, the NVMe security specific field indicates
+	which reply memory buffer target.
+
+-x <size>::
+--size=<size>::
+	Size of buffer to allocate. One success it will be printed
+	to STDOUT.
+
+-p <security-protocol>::
+--secp=<security-protocol>::
+	Security Protocol: This field specifies the security protocol
+	as defined in SPC-4. The controller shall fail the command with
+	Invalid Parameter indicated if a reserved value of the Security

+The Security Send command is used to transfer security protocol data to the controller\&. The data structure transferred to the controller as part of this command contains security protocol specific commands to be performed by the controller\&. The data structure transferred may also contain data or parameters associated with the security protocol commands\&. Status and data that is to be returned to the host for the security protocol commands submitted by a Security Send command are retrieved with the Security Receive command\&.
+.sp
+The association between a Security Send command and subsequent Security Receive command is Security Protocol field dependent as defined in SPC\-4\&.

+DESCRIPTION
+-----------
+The Security Send command is used to transfer security protocol data
+to the controller. The data structure transferred to the controller
+as part of this command contains security protocol specific commands
+to be performed by the controller. The data structure transferred may
+also contain data or parameters associated with the security protocol
+commands. Status and data that is to be returned to the host for the
+security protocol commands submitted by a Security Send command are
+retrieved with the Security Receive command.
+
+The association between a Security Send command and subsequent Security
+Receive command is Security Protocol field dependent as defined in SPC-4.
+

+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer or the json format\&.
+.sp
+By default the log is printed out in the normal readable format\&.

+.sp
+Submits an NVMe Set Feature admin command and returns the applicable results\&. This may be the feature\(cqs value, or may also include a feature structure if the feature requires it (ex: LBA Range Type)\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the value sent to the device is displayed
+.SH "OPTIONS"

+.RE
+.PP
+\-l <data\-len>, \-\-data\-len=<data\-len>
+.RS 4
+The data length for the buffer submitted for this feature\&. Most known features do not use this value\&. The exceptions are LBA Range Type and host identifier\&.
+.RE
+.PP
+\-d <data\-file>, \-\-data=<data\-file>
+.RS 4
+The data file for the buffer submitted for this feature\&. Most known features do not use this value\&. The exceptions is LBA Range Type and host identifier\&. This defaults to STDIN so files and echo can be piped\&.

+DESCRIPTION
+-----------
+Submits an NVMe Set Feature admin command and returns the applicable
+results. This may be the feature's value, or may also include a feature
+structure if the feature requires it (ex: LBA Range Type).
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the value sent to the device is displayed
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Sets the feature for the given nsid. This is optional and
+	most features do not use this value.
+
+-f <fid>::
+--feature-id=<fid>::
+	The feature id to send with the command. Value provided should
+	be in hex.
+
+-l <data-len>::
+--data-len=<data-len>::
+	The data length for the buffer submitted for this feature. Most
+	known features do not use this value. The exceptions are LBA
+	Range Type and host identifier.
+
+-d <data-file>::
+--data=<data-file>::
+	The data file for the buffer submitted for this feature. Most
+	known features do not use this value. The exceptions is LBA
+	Range Type and host identifier. This defaults to STDIN so files
+	and echo can be piped.
+
+-v <value>::
+--value=<value>::
+	The value for command dword 11, the value you want to set the
+	feature to.
+
+-s::
+--save::
+	Save the attribute so that it persists through all power states and resets.	
+
+-U <uuid-index>::
+--uuid-index=<uuid-index>::
+	UUID Index of the feature
+
+EXAMPLES

+.sp
+For the NVMe over PCIe device given, sends an identify namespace command and provides the result and returned structure\&. For the NVMe over Fabrics device given, sends a fabric command and provides the result and returned structure\&.
+.sp
+The <device> parameter is mandatory and must be the nvme admin character device (ex: /dev/nvme0)\&. For NVMe over PCIe, the program uses knowledge of the sysfs layout to map the device to the pci resource stored there and mmaps the memory to get access to the registers\&. For NVMe over Fabrics, the programs sends a fabric command to get the properties of the target NVMe controller\&. Only the supported properties are displayed\&.

+NAME
+----
+nvme-show-regs - Reads and shows the defined NVMe controller registers for
+NVMe over PCIe or the controller properties for NVMe over Fabrics.
+
+SYNOPSIS
+--------
+[verse]
+'nvme show-regs' <device>	[--human-readable | -H]
+				[--output-format=<FMT> | -o <FMT>]
+
+DESCRIPTION
+-----------
+For the NVMe over PCIe device given, sends an identify namespace command and
+provides the result and returned structure.
+For the NVMe over Fabrics device given, sends a fabric command and provides
+the result and returned structure.
+
+The <device> parameter is mandatory and must be the nvme admin character
+device (ex: /dev/nvme0). For NVMe over PCIe, the program uses knowledge of the
+sysfs layout to map the device to the pci resource stored there and mmaps the
+memory to get access to the registers. For NVMe over Fabrics, the programs
+sends a fabric command to get the properties of the target NVMe controller.
+Only the supported properties are displayed.
+
+OPTIONS
+-------
+-H::
+--human-readable::
+       Display registers or supported properties in human readable format.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Show the NVMe over PCIe controller registers or the NVMe over Fabric controller
+properties in a binary format:
++
+------------
+# nvme show-regs /dev/nvme0 -o binary
+------------
+* Show the NVMe over PCIe controller registers or the NVMe over Fabric controller
+properties in a human readable format:
++
+------------
+# nvme show-regs /dev/nvme0 -H
+------------
+* Show the NVMe over PCIe controller registers or NVMe-oF controller properties
+in a json format:
++
+------------
+# nvme show-regs /dev/nvme0 -o json

+.sp
+Retrieves the NVMe SMART log page from an NVMe device and provides the returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned smart log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.
+.SH "OPTIONS"
+.PP
+\-n <nsid>, \-\-namespace\-id=<nsid>
+.RS 4
+Retrieve the SMART log for the given nsid\&. This is optional and its success may depend on the device\(cqs capabilities to provide this log on a per\-namespace basis (see the NVMe Identify Controller for this capability)\&. The default nsid to use is 0xffffffff for the device global SMART log\&.
+.RE
+.PP
+\-b, \-\-raw\-binary

+Print the raw SMART log buffer to stdout\&.

+NAME
+----
+nvme-smart-log - Send NVMe SMART log page request, returns result and log
+
+SYNOPSIS
+--------
+[verse]
+'nvme smart-log' <device> [--namespace-id=<nsid> | -n <nsid>]
+			[--raw-binary | -b]
+			[--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Retrieves the NVMe SMART log page from an NVMe device and provides the returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned smart log structure may be returned in one of
+several ways depending on the option flags; the structure may parsed by
+the program and printed in a readable format or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Retrieve the SMART log for the given nsid. This is optional
+	and its success may depend on the device's capabilities to
+	provide this log on a per-namespace basis (see the NVMe Identify
+	Controller for this capability). The default nsid to use is
+	0xffffffff for the device global SMART log.
+
+-b::
+--raw-binary::
+	Print the raw SMART log buffer to stdout.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Print the SMART log page in a human readable format:
++
+------------
+# nvme smart-log /dev/nvme0
+------------
++
+
+* Print the raw SMART log to a file:
++
+------------
+# nvme smart-log /dev/nvme0 --raw-binary > smart_log.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.

+===============================
+
+NAME
+----
+nvme-toshiba-vs-internal-log - Retrieve a Toshiba device's vendor specific internal log and either save to file or dump the contents.
+
+SYNOPSIS
+--------
+[verse]
+'nvme toshiba vs-internal-log ' <device>
+		[--output-file=<FILE>, -o <FILE>] (optional)
+		[--saved-log, -s] (optional)
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends the Toshiba internal device log
+request and either saves the result to a file or dumps the content to stdout.
+
+The <device> parameter is mandatory and may be either the NVMe
+character device (ex: /dev/nvme0), or a namespace block device (ex:
+/dev/nvme0n1). 
+
+The log is associated with the controller rather than any
+namespaces.
+
+Two logs exist, the current log and the previous log.
+
+This will only work on Toshiba devices supporting this feature.
+
+Note: The logs are quite large - typically 100's of MB. This command can take several minutes to complete. 
+A progress runner is included when data is written to file and a page count is included in the stdout dump.

+.fi
+.SH "DESCRIPTION"
+.sp
+This command automates the process of collecting SMART data periodically and saving the data in a ready\-to\-analyze format\&. Each entry is saved with timestamp and in csv format\&. Users can use excel to analyze the data\&. Some examples of use cases are collecting SMART data for temperature characterization, collecting data to calculate endurance, or collecting SMART data during a test or during normal operation\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the command generates a log file, which contains an entry for identify device (current features & settings) and periodic entries of SMART data\&.
+.sp
+This command runs for the time specified by the option <run\-time>, and collects SMART data at the frequency specified by the option <freq>\&. If the output file name is not specified, this command will generate a file name that include model string and serial number of the device\&.
+.sp
+If the test\-name option is specified, it will be recorded in the log file and be used as part of the log file name\&.
+.SH "OPTIONS"

+.RS 4
+(optional) Number of hours to log data (default = 20 hours)
+.RE
+.PP

+.RS 4
+(optional) How often you want to log SMART data (0\&.25 = 15\*(Aq , 0\&.5 = 30\*(Aq , 1 = 1 hour, 2 = 2 hours, etc\&.)\&. Default = 10 hours\&.
+.RE
+.PP
+\-o <FILE>, \-\-output\-file=<FILE>
+.RS 4
+(optional) Name of the log file (give it a name that easy for you to remember what the test is)\&. You can leave it blank too, the file name will be generated as <model string>\-<serial number>\-<test name>\&.txt\&.

+<div class="paragraph"><p>This command automates the process of collecting SMART data periodically and

+saving the data in a ready-to-analyze format. Each entry is saved

+with timestamp and in csv format. Users can use excel to analyze the data.

+Some examples of use cases are collecting SMART data for temperature characterization,

+collecting data to calculate endurance, or collecting SMART data during a test

+or during normal operation.</p></div>

+<div class="paragraph"><p>The &lt;device&gt; parameter is mandatory and may be either the NVMe character

+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).</p></div>

+<div class="paragraph"><p>On success, the command generates a log file, which contains an entry for identify device

+(current features &amp; settings) and periodic entries of SMART data.</p></div>

+<div class="paragraph"><p>This command runs for the time specified by the option &lt;run-time&gt;, and collects SMART data

+at the frequency specified by the option &lt;freq&gt;. If the output file name is not specified,

+this command will generate a file name that include model string and serial number of the device.</p></div>

+<div class="paragraph"><p>If the test-name option is specified, it will be recorded in the log file and be used as part

+of the log file name.</p></div>

+nvme-virtium-save-smart-to-vtview-log(1)
+========================================
+
+NAME
+----
+nvme-virtium-save-smart-to-vtview-log - Periodically save smart attributes into a log file (csv format).
+
+SYNOPSIS
+--------
+[verse]
+'nvme virtium save-smart-to-vtview-log' <device> [--run-time=<NUM> | -r <NUM>]
+			[--freq=<NUM> | -f <NUM>]
+			[--output-file=<FILE> | -o <FILE>]
+			[--test-name=<NAME> | -n <NAME>]
+			
+DESCRIPTION
+-----------
+This command automates the process of collecting SMART data periodically and
+saving the data in a ready-to-analyze format. Each entry is saved 
+with timestamp and in csv format. Users can use excel to analyze the data.
+Some examples of use cases are collecting SMART data for temperature characterization,
+collecting data to calculate endurance, or collecting SMART data during a test
+or during normal operation.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the command generates a log file, which contains an entry for identify device
+(current features & settings) and periodic entries of SMART data. 
+
+This command runs for the time specified by the option <run-time>, and collects SMART data
+at the frequency specified by the option <freq>. If the output file name is not specified,
+this command will generate a file name that include model string and serial number of the device.
+
+If the test-name option is specified, it will be recorded in the log file and be used as part
+of the log file name.
+
+OPTIONS
+-------
+-r <NUM>::
+--run-time=<NUM>::
+	(optional) Number of hours to log data (default = 20 hours)
+
+-f <NUM>::
+--freq=<NUM>::
+	(optional) How often you want to log SMART data
+	(0.25 = 15' , 0.5 = 30' , 1 = 1 hour, 2 = 2 hours, etc.). Default = 10 hours.
+
+-o <FILE>::
+--output-file=<FILE>::
+    (optional) Name of the log file (give it a name that easy for you to remember 
+	what the test is). You can leave it blank too, the file name will be generated
+	as <model string>-<serial number>-<test name>.txt.
+
+-n <NAME>::
+--test-name=<NAME>::
+    (optional) Name of the test you are doing. We use this string as part of the name of the log file.
+	
+	
+EXAMPLES
+--------
+* Temperature characterization:
++
+------------
+# nvme virtium save-smart-to-vtview-log /dev/yourDevice --run-time=100 --record-frequency=0.25 --test-name=burn-in-at-(-40)
+------------
++
+
+* Endurance testing:
++
+------------
+# nvme virtium save-smart-to-vtview-log /dev/yourDevice --run-time=100 --record-frequency=1 --test-name=Endurance-test-JEDEG-219-workload
+------------
++
+
+* Just logging: Default logging is run for 20 hours and log every 10 hours.

+For the NVMe device given, sends an identify controller command and provides the result and returned structure\&.

+.sp
+On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.

+===================

+NAME
+----
+nvme-wdc-id-ctrl - Send NVMe Identify Controller, return result and structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme wdc id-ctrl' <device> [-v | --vendor-specific] [-b | --raw-binary]
+			[-H | --human-readable]
+			[-o <fmt> | --output-format=<fmt>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends an identify controller command and
+provides the result and returned structure.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+This will only work on WDC devices supporting this feature.
+Results for any other device are undefined.
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+If having the program decode the output for readability, this version
+will decode WDC vendor unique portions of the structure.
+
+OPTIONS
+-------
+-b::
+--raw-binary::
+	Print the raw buffer to stdout. Structure is not parsed by
+	program. This overrides the vendor specific and human readable options.
+
+-v::
+--vendor-specific::
+	In addition to parsing known fields, this option will dump
+	the vendor specific region of the structure in hex with ascii
+	interpretation.
+
+-H::
+--human-readable::
+	This option will parse and format many of the bit fields
+	into human-readable formats.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:

+nvme-wdc-vs-device-waf - Calculates the device write amplification factor and
+prints both TLC and SLC results
+
+SYNOPSIS
+--------
+[verse]
+'nvme wdc vs-device-waf' <device> [--output-format=<normal|json> -o <normal|json>]
+			[--namespace-id=<nsid> | -n <nsid>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, calculates the device TLC and SLC write 
+amplification factor.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1).
+
+This will only work on WDC devices supporting this feature.
+Results for any other device are undefined.
+
+On success it returns 0, error code otherwise.
+
+OPTIONS
+-------
+-o <format>::
+--output-format=<format>::
+	Set the reporting format to 'normal', or
+	'json'. Only one output format can be used at a time.
+	Default is normal.
+
+-n <nsid>::
+--namespace-id=<nsid>::
+	Sets the command's nsid value to the given nsid. Defaults to
+	0xffffffff if not given. This option may not affect anything
+	depending on the log page, which may or may not be specific to
+	a namespace.

+
+DESCRIPTION
+-----------
+For the NVMe device given, read a Vendor Unique WDC log page that returns the firmware activation
+history. 
+
+The <device> parameter is mandatory and must be the NVMe character device (ex: /dev/nvme0).
+
+This will only work on WDC devices supporting this feature.
+Results for any other device are undefined.
+

+nvme-wdc-vs-internal-log(1)
+===========================
+
+NAME
+----
+nvme-wdc-vs-internal-log - Retrieve WDC device's internal firmware log and save to file.
+
+SYNOPSIS
+--------
+[verse]
+'nvme wdc vs-internal-log' <device> [--output-file=<FILE>, -o <FILE>] [--transfer-size=<SIZE>, -s <SIZE>]
+    [--data-area=<DATA AREA>, -d <DATA_AREA>] [--file-size=<FILE SIZE>, -f <FILE SIZE>] [--offset=<OFFSET>, -e <OFFSET>]
+    [--type=<TYPE>, -t <type>] [--verbose, -v]
+
+DESCRIPTION
+-----------
+
+For the NVMe device given, sends the WDC Vendor Specific Internal Log request and saves
+the result to a file.
+
+The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0).
+
+This will only work on WDC devices supporting this feature.
+Results for any other device are undefined.
+
+OPTIONS
+-------
+-o <FILE>::
+--output-file=<FILE>::
+	Output file; defaults to device serial number followed by "_internal_fw_log_<date>_<time>.bin" suffix
+
+-s <SIZE>::
+--transfer-size=<SIZE>::
+    Transfer size; defaults to 0x10000 (65536 decimal) bytes
+
+-d <DATA AREA>::
+--data-area=<DATA AREA>::
+    DUI data area to retrieve.  The DUI data areas from 1 to <DATA AREA> will be retrieved.  This parameter
+    is currently only supported on the SN340, SN640, SN730, and SN840 devices.
+
+-f <FILE SIZE>::
+--file-size=<FILE SIZE>::
+    Specifies the desired size of the data file starting at the passed in offset.  This allows the user to
+    retrieve the data in several smaller files of the passed in size.  This parameter is currently only
+    supported on the SN340 device.
+
+-e <OFFSET>::
+--offset=<OFFSET>::
+	Specifies the data offset at which to start retrieving the data.  This parameter is used in combination
+	with the file size parameter to retrieve the data in several smaller files.  This parameter is currently
+    only supported on the SN340 device.
+
+-t <TYPE>::
+--type=<TYPE>::
+	Specifies the telemetry type - NONE, HOST, or CONTROLLER.  This parameter is used to get either the host
+	generated or controller initiated telemetry log page.  If not specified or none is specified, the command
+    will return the default E6 log data.  This parameter is currently only supported on the SN640 and SN840
+    devices.
+
+-v <VERBOSE>::
+--verbose=<VERBOSE>::
+	Provides additional debug messages for certain drives.
+
+EXAMPLES
+--------
+* Gets the internal firmware log from the device and saves to default file in current directory (e.g. STM00019F3F9_internal_fw_log_20171127_095704.bin):
++
+------------
+# nvme wdc vs-internal-log /dev/nvme0

+* Gets the internal firmware log from the device and saves to defined file in current directory (e.g. test.bin):
++
+------------
+# nvme wdc vs-internal-log /dev/nvme0 -o test.bin
+------------
+* Gets the internal firmware log from the device and saves to defined file with pathname (e.g. /tmp/test):
++
+------------
+# nvme wdc vs-internal-log /dev/nvme0 -o /tmp/test
+------------
+* Gets the internal firmware log from the device transferring the data in 64k chunks and saves to default file in current directory (e.g. STM00019F3F9_internal_fw_log_20171127_100754.bin):
++
+------------
+# nvme wdc vs-internal-log /dev/nvme0 -s 0x10000
+------------
+* Gets the internal firmware log from the device transferring the data in 16k chunks and saves to default file in current directory (e.g. STM00019F3F9_internal_fw_log_20171127_100950.bin):
++
+------------
+# nvme wdc vs-internal-log /dev/nvme0 -s 16384
+------------
+* Gets the internal firmware log up to data area 3 from the device in 3 files of 0x1000000 bytes:
++
+------------
+# nvme wdc vs-internal-log /dev/nvme0 -d 3 -f 0x1000000 -t 0x0000000 -o /tmp/sn340_dui_data_1.bin
+# nvme wdc vs-internal-log /dev/nvme0 -d 3 -f 0x1000000 -t 0x1000000 -o /tmp/sn340_dui_data_2.bin
+# nvme wdc vs-internal-log /dev/nvme0 -d 3 -f 0x1000000 -t 0x2000000 -o /tmp/sn340_dui_data_3.bin
+------------
+* Gets the host telemetry log page to data area 3 from the device and stores it in file host-telem-log-da3.bin:
++
+------------
+# nvme wdc vs-internal-log /dev/nvme1 -t host -o host-telem-log-da3.bin -d 3
+------------
+* Gets the controller telemetry log page to data area 3 from the device and stores it in file ctlr-telem-log-da3.bin:
++
+------------

+nvme-wdc-vs-smart-add-log - Send NVMe WDC vs-smart-add-log Vendor Unique Command, return result
+
+SYNOPSIS
+--------
+[verse]
+'nvme wdc vs-smart-add-log' <device> [--interval=<NUM>, -i <NUM>] 
+			[--output-format=<normal|json> -o <normal|json>]
+			[--log-page-version=<NUM>, -l <NUM>] 
+			[--log-page-mask=<LIST>, -p <LIST>] 
+			[--namespace-id=<nsid> | -n <nsid>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, send a Vendor Unique WDC vs-smart-add-log command and
+provide the additional smart log. 
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1).
+
+This will only work on WDC devices supporting this feature.
+Results for any other device are undefined.
+
+On success it returns 0, error code otherwise.
+
+OPTIONS
+-------
+-i <NUM>::
+--interval=<NUM>::
+	Return the statistics from specific interval, defaults to 14.  This parameter is only valid for the 0xC1 log page
+	and ignored for all other log pages.
+
+-o <format>::
+--output-format=<format>::
+	Set the reporting format to 'normal', or
+	'json'. Only one output format can be used at a time.
+	Default is normal.
+
+-l <NUM>::
+--log-page-version=<NUM>::
+    Log Page Version: 0 = vendor, 1 = WDC.  This parameter is only valid for the 0xC0 log page and ignored for all
+    other log pages.
+
+-p <LIST>::
+--log-page-mask=<LIST>::
+    Supply a comma separated list of desired log pages to display.
+    The possible values are 0xc0, 0xc1, 0xca, 0xd0.  
+    Note: Not all pages are supported on all drives.  
+    The default is to display all supported log pages.  
+
+-n <nsid>::
+--namespace-id=<nsid>::
+	Sets the command's nsid value to the given nsid. Defaults to
+	0xffffffff if not given. This option may not affect anything
+	depending on the log page, which may or may not be specific to
+	a namespace.
+
+Valid Interval values and description :-
+
+[cols="2*", frame="topbot", align="center", options="header"]
+|===
+|Value |Description
+
+|*1*
+|Most recent five (5) minute accumulated set.
+
+|*2-12*
+|Previous five (5) minute accumulated sets.
+
+|*13*
+|The accumulated total of sets 1 through 12 that contain the previous hour of
+accumulated statistics.
+
+|*14*
+|The statistical set accumulated since power-up.

+-S <spec>::
+--dir-spec=<spec>::

+-D <dsm>::
+--dsm=<dsm>::
+	The optional data set management attributes for this command. The argument
+	for this is the least significant 8 bits of the DSM field in a write
+	command; the most significant 16 bits of the field come from the directive
+	specific field, if used. This may be used to set attributes for

+nvme-zns-report-zones - Retrieve and display the Report Zones data structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme zns report-zones' <device> [--namespace-id=<NUM> | -n <NUM>]
+				 [--start-lba=<IONUM> | -s <IONUM>]
+				 [--descs=<NUM> | -d <NUM>]
+				 [--state=<NUM> | -S <NUM>]
+				 [--extended | -e]
+				 [--partial | -p]
+				 [--verbose | -v]
+				 [--output-format=<FMT> | -o <FMT>]
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends the Zone Management Receive command with the
+Zone Receive Action set to either Report Zones or Extended Report Zones,
+depending on the 'extended' option.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the data structure returned by the device will be decoded and
+displayed in one of several ways. 
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+	Use the provided namespace id for the command. If not provided, the
+	namespace id of the block device will be used. If the command is issued
+	to a non-block device, the parameter is required.
+
+-s <lba>::
+--start-lba=<lba>::
+	The starting LBA of the zone to begin the report
+
+-d <NUM>::
+--descs=<NUM>::
+	The number of descriptors to request in the report.
+
+-S <NUM>::
+--state=<NUM>::
+	The state of zones to request in the report. Known values include:
++
+[]
+|=================
+|Value|Definition
+|0|List all zones (default)
+|1|Empty State
+|2|Implicitly Opened State
+|3|Explicitly Opened State
+|4|Closed State
+|5|Full State
+|6|Read Only State
+|7|Offline State
+|=================
+
+-e::
+--extended::
+	Request to use the Extended Report Zones option. The extended data is
+	not decoded.
+
+-p::
+--partial::
+	If set, the device will return the number of zones that match the state
+	rather than the number of zones returned in the report.
+
+-v::
+--verbose::
+	Increase the information detail in the output.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the report for 16 zones, and display the known
+fields in a human readable format:
++
+------------
+# nvme zns report-zones /dev/nvme0 -n 1 -d 16
+------------
++
+
+* Show the output in json format with extra details
++
+------------
+# nvme zns report-zones /dev/nvme0 -n 1 -d 16 -o json

+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+	Use the provided namespace id for the command. If not provided, the
+	namespace id of the block device will be used. If the command is issued
+	to a non-block device, the parameter is required.
+
+-s <lba>::
+--start-lba=<lba>::
+	The starting LBA of the zone to reset.

+For the NVMe device given, issues the Zone Management Receive command with the requested receive action and additional action specific parameters\&. This is the generic interface provided for forward compatibility as new actions are created that this program isn\(cqt aware of at the time of its development\&.

+DESCRIPTION
+-----------
+For the NVMe device given, issues the Zone Management Receive command with the
+requested receive action and additional action specific parameters. This is the
+generic interface provided for forward compatibility as new actions are created
+that this program isn't aware of at the time of its development. As such, this
+is a generic command that does not do any additional decoding for specific
+types of data received. This will only report the data as a hex dump, or
+binary. 
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+	Use the provided namespace id for the command. If not provided, the
+	namespace id of the block device will be used. If the command is issued
+	to a non-block device, the parameter is required.
+
+-s <lba>::
+--start-lba=<lba>::
+	The starting LBA of the zone to manage receive.
+
+--data-len=<NUM>
+-l <NUM>
+	Received data buffer length
+
+-z <NUM>::
+--zra=<NUM>::
+	Zone Receive Action
+
+-a <NUM>
+--zrasf=<NUM>
+	Zone Receive Action Specific field
+
+-f::
+--zra-spec-feat::
+	Enable Zone Receive Action Specific features
+
+-o <FMT>::
+--output-format=<FMT>::
+	Output format: normal|json|binary
+
+EXAMPLES

+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+	Use the provided namespace id for the command. If not provided, the
+	namespace id of the block device will be used. If the command is issued
+	to a non-block device, the parameter is required.
+
+-l <lba>::
+--lba=<lba>::
+	The LBA to flush up to.
+
+-t <timeout>::
+--timeout=<timeout>::
+	Override default timeout value. In milliseconds.
+
+EXAMPLES
+--------

+.SH "DESCRIPTION"
+.sp
+NVM\-Express is a fast, scalable host controller interface designed to address the needs for not only PCI Express based solid state drives, but also NVMe\-oF(over fabrics)\&.
+.sp
+This \fInvme\fR program is a user space utility to provide standards compliant tooling for NVM\-Express drives\&. It was made specifically for Linux as it relies on the IOCTLs defined by the mainline kernel driver\&.
+.SH "NVME COMMANDS"
+.sp
+The utility has sub\-commands for all admin and io commands defined in the specification and for displaying controller registers\&. There is also an option to submit completely arbitrary commands\&. For a list of commands available, run "nvme help"\&.

+NAME
+----
+nvme - the NVMe storage command line interface utility (nvme-cli)
+
+SYNOPSIS
+--------
+built-in plugin:
+[verse]
+'nvme' <command> <device> [<args>]
+
+extension plugins:
+[verse]
+'nvme' <plugin> <command> <device> [<args>]
+
+DESCRIPTION
+-----------
+NVM-Express is a fast, scalable host controller interface designed to
+address the needs for not only PCI Express based solid state drives, but
+also NVMe-oF(over fabrics).
+
+This 'nvme' program is a user space utility to provide standards compliant
+tooling for NVM-Express drives. It was made specifically for Linux as
+it relies on the IOCTLs defined by the mainline kernel driver.
+
+NVME COMMANDS
+-------------
+The utility has sub-commands for all admin and io commands defined in the
+specification and for displaying controller registers. There is also an
+option to submit completely arbitrary commands. For a list of commands
+available, run "nvme help".
+
+nvme cli sub-commands

+Plugins/Vendor extension commands
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+include::cmd-plugins.txt[]
+
+RETURNS
+-------
+All commands will behave the same, they will return 0 on success and 1 on
+failure.
+
+FURTHER DOCUMENTATION

+GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc., <http://fsf.org/>
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    {description}
+    Copyright (C) {year}  {fullname}
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  {signature of Ty Coon}, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+### OpenEmbedded/Yocto
+
+An [nvme-cli recipe](https://layers.openembedded.org/layerindex/recipe/88631/)
+is available as part of the `meta-openembeded` layer collection.
+
+### Buildroot
+
+`nvme-cli` is available as [buildroot](https://buildroot.org) package. The
+package is named `nvme`.
+
+### Other Distros
+
+TBD
+
+## Developers
+
+You may wish to add a new command or possibly an entirely new plug-in
+for some special extension outside the spec.
+
+This project provides macros that help generate the code for you. If
+you're interested in how that works, it is very similar to how trace
+events are created by Linux kernel's 'ftrace' component.
+
+### Add command to existing built-in
+
+The first thing to do is define a new command entry in the command
+list. This is declared in nvme-builtin.h. Simply append a new "ENTRY" into
+the list. The ENTRY normally takes three arguments: the "name" of the 
+subcommand (this is what the user will type at the command line to invoke
+your command), a short help description of what your command does, and the
+name of the function callback that you're going to write. Additionally,
+You can declare an alias name of subcommand with fourth argument, if needed.
+
+After the ENTRY is defined, you need to implement the callback. It takes
+four arguments: argc, argv, the command structure associated with the
+callback, and the plug-in structure that contains that command. The
+prototype looks like this:
+
+  ```c
+  int f(int argc, char **argv, struct command *cmd, struct plugin *plugin);
+  ```
+
+The argc and argv are adjusted from the command line arguments to start
+after the sub-command. So if the command line is "nvme foo --option=bar",
+the argc is 1 and argv starts at "--option".
+
+You can then define argument parsing for your sub-command's specific
+options then do some command specific action in your callback.
+
+### Add a new plugin
+
+The nvme-cli provides macros to make define a new plug-in simpler. You
+can certainly do all this by hand if you want, but it should be easier
+to get going using the macros. To start, first create a header file
+to define your plugin. This is where you will give your plugin a name,
+description, and define all the sub-commands your plugin implements.
+
+There is a very important order on how to define the plugin. The following
+is a basic example on how to start this:
+
+File: foo-plugin.h
+```c
+#undef CMD_INC_FILE
+#define CMD_INC_FILE plugins/foo/foo-plugin
+
+#if !defined(FOO) || defined(CMD_HEADER_MULTI_READ)
+#define FOO
+
+#include "cmd.h"
+
+PLUGIN(NAME("foo", "Foo plugin"),
+	COMMAND_LIST(
+		ENTRY("bar", "foo bar", bar)
+		ENTRY("baz", "foo baz", baz)
+		ENTRY("qux", "foo quz", qux)
+	)
+);
+
+#endif
+
+#include "define_cmd.h"
+```
+
+In order to have the compiler generate the plugin through the xmacro
+expansion, you need to include this header in your source file, with
+pre-defining macro directive to create the commands.
+
+To get started from the above example, we just need to define "CREATE_CMD"
+and include the header:
+
+File: foo-plugin.c
+```c
+#include "nvme.h"
+
+#define CREATE_CMD
+#include "foo-plugin.h"
+```
+
+After that, you just need to implement the functions you defined in each
+ENTRY, then append the object file name to the meson.build "sources".
+
+## meson tips
+
+In case meson doesn't find libnvme header files (via pkg-config) it 
+will fallback using subprojects.  meson checks out libnvme in 
+subprojects directory as git tree once to the commit level specified 
+in the libnvme.wrap file revision parm.  After this initial checkout,
+the libnvme code level will not change unless explicitly told.  That 
+means if the current branch is updated via git, the subprojects/libnvme
+branch will not updated accordingly.  To update it, either use the 
+normal git operations or the command: 
+
+    $ meson subprojects update
+
+## Dependency
+
+libnvme depends on the /sys/class/nvme-subsystem interface which was
+introduced in the Linux kernel release v4.15. Hence nvme-cli 2.x is
+only working on kernels >= v4.15. For older kernels nvme-cli 1.x is
+recommended to be used.
+
+## How to contribute
+
+There are two ways to send code changes to the project. The first one
+is by sending the changes to linux-nvme@lists.infradead.org. The
+second one is by posting a pull request on github. In both cases
+please follow the Linux contributions guidelines as documented in
+
+https://docs.kernel.org/process/submitting-patches.html#
+
+That means the changes should be a clean series (no merges should be
+present in a github PR for example) and every commit should build.

+
+### How to cleanup your series before creating PR
+
+This example here assumes, the changes are in a branch called
+fix-something, which branched away from master in the past. In the
+meantime the upstream project has changed, hence the fix-something
+branch is not based on the current HEAD. Before posting the PR, the
+branch should be rebased on the current HEAD and retest everything.
+
+For example rebasing can be done by following steps
+
+```shell
+# Update master branch
+#   upstream == https://github.com/linux-nvme/nvme-cli.git
+$ git switch master
+$ git fetch --all
+$ git reset --hard upstream/master
+
+# Make sure all dependencies are up to date and make a sanity build
+$ meson subprojects update
+$ ninja -C .build
+
+# Go back to the fix-something branch
+$ git switch fix-something
+
+# Rebase it to the current HEAD
+$ git rebase master
+[fixup all merge conflicts]
+[retest]
+
+# Push your changes to github and trigger a PR
+$ git push -u origin fix-something
+```

+ * These assertions are most useful when two parts of the code must be kept in

+ *
+ *	struct foo {

+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer exclusive Copyright and Related Rights (defined below) upon the creator and subsequent owner(s) (each and all, an "owner") of an original work of authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for the purpose of contributing to a commons of creative, cultural and scientific works ("Commons") that the public can reliably and without fear of later claims of infringement build upon, modify, incorporate in other works, reuse and redistribute as freely as possible in any form whatsoever and for any purposes, including without limitation commercial purposes. These owners may contribute to the Commons to promote the ideal of a free culture and the further production of creative, cultural and scientific works, or to gain reputation or greater distribution for their Work in part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any expectation of additional consideration or compensation, the person associating CC0 with a Work (the "Affirmer"), to the extent that he or she is an owner of Copyright and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and publicly distribute the Work under its terms, with knowledge of his or her Copyright and Related Rights in the Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be protected by copyright and related or neighboring rights ("Copyright and Related Rights"). Copyright and Related Rights include, but are not limited to, the following:
+
+    the right to reproduce, adapt, distribute, perform, display, communicate, and translate a Work;
+    moral rights retained by the original author(s) and/or performer(s);
+    publicity and privacy rights pertaining to a person's image or likeness depicted in a Work;
+    rights protecting against unfair competition in regards to a Work, subject to the limitations in paragraph 4(a), below;
+    rights protecting the extraction, dissemination, use and reuse of data in a Work;
+    database rights (such as those arising under Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, and under any national implementation thereof, including any amended or successor version of such directive); and
+    other similar, equivalent or corresponding rights throughout the world based on applicable law or treaty, and any national implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of, applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and unconditionally waives, abandons, and surrenders all of Affirmer's Copyright and Related Rights and associated claims and causes of action, whether now known or unknown (including existing as well as future claims and causes of action), in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each member of the public at large and to the detriment of Affirmer's heirs and successors, fully intending that such Waiver shall not be subject to revocation, rescission, cancellation, termination, or any other legal or equitable action to disrupt the quiet enjoyment of the Work by the public as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be judged legally invalid or ineffective under applicable law, then the Waiver shall be preserved to the maximum extent permitted taking into account Affirmer's express Statement of Purpose. In addition, to the extent the Waiver is so judged Affirmer hereby grants to each affected person a royalty-free, non transferable, non sublicensable, non exclusive, irrevocable and unconditional license to exercise Affirmer's Copyright and Related Rights in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "License"). The License shall be deemed effective as of the date CC0 was applied by Affirmer to the Work. Should any part of the License for any reason be judged legally invalid or ineffective under applicable law, such partial invalidity or ineffectiveness shall not invalidate the remainder of the License, and in such case Affirmer hereby affirms that he or she will not (i) exercise any of his or her remaining Copyright and Related Rights in the Work or (ii) assert any associated claims and causes of action with respect to the Work, in either case contrary to Affirmer's express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+    No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document.
+    Affirmer offers the Work as-is and makes no representations or warranties of any kind concerning the Work, express, implied, statutory or otherwise, including without limitation warranties of title, merchantability, fitness for a particular purpose, non infringement, or the absence of latent or other defects, accuracy, or the present or absence of errors, whether or not discoverable, all to the greatest extent permissible under applicable law.
+    Affirmer disclaims responsibility for clearing rights of other persons that may apply to the Work or any use thereof, including without limitation any person's Copyright and Related Rights in the Work. Further, Affirmer disclaims responsibility for obtaining any necessary consents, permissions or other rights required for any use of the Work.
+    Affirmer understands and acknowledges that Creative Commons is not a party to this document and has no duty or obligation with respect to this CC0 or use of the Work.

+
+Setting Up NVMe Tab Autocompletion for bash or zsh
+==================================================
+
+If your working shell is bash...
+--------------------------------
+the following gets bash autocompletion to behave properly
+#echo "bind 'set show-all-if-ambiguous on'" >> ~/.bashrc
+#echo "bind 'set show-all-if-unmodified on'" >> ~/.bashrc
+#echo "bind 'set completion-ignore-case on'" >> ~/.bashrc
+#echo "bind 'set completion-map-case on'" >> ~/.bashrc
+
+add NVMe autocompletion script to your autocompletes directory
+#cp `pwd`/bash-nvme-completion.sh /etc/bash_completion.d/nvme
+
+make sure this bash knows where everything is
+#source /etc/bash_completion.d/nvme && source ~/.bashrc
+
+you should be able to autocomplete with the nvme utility now
+(double TABs still apply)! If autocompleting has disappeared,
+just re-source nvme and .bashrc. To see a full list of auto-completable
+NVMe commands, type "nvme help " and hit TAB.
+
+You may also need to uncomment the "enable bash completion in interactive
+shells" part of /etc/bash.bashrc, which hopefully looks something like:
+
+if [ -f /usr/share/bash-completion/bash_completion ]; then
+	. /usr/share/bash-completion/bash_completion
+elif [ -f /etc/bash_completion ]; then
+	. /etc/bash_completion
+fi
+
+(don't bother with the shopt part, your Bash version might not support shopt).
+
+Bash footnote: for bash vers >= 4.2, it appears to be the case that
+menu-complete **no longer works.** If the bash dev folks ever re-patch this,
+try binding TAB to menu-complete to cycle through the NVMe subcommand matches
+on whatever you typed.
+
+if your working shell is zsh...
+-------------------------------
+create the zsh completions directory if you don't have it
+#if [ ! -e "~/.zsh" ]; then
+#	mkdir ~/.zsh
+#	mkdir ~/.zsh/completion
+#fi
+
+#cp `pwd`/_nvme ~/.zsh/completion/_nvme
+
+add compinit if you don't have it in your .zshrc
+#echo "autoload -Uz compinit && compinit" >> ~/.zshrc
+
+add nvme autocompletions to your .zshrc
+#echo "# source for tab autocompletions" >> ~/.zshrc
+#echo "fpath=(~/.zsh/completion $fpath)" >> ~/.zshrc
+#echo "source ~/.zsh/completion/_nvme" >> ~/.zshrc
+
+make sure this zsh knows where everything is
+#source ~/.zsh/completion/_nvme && source ~/.zshrc
+
+You should be able to autocomplete with the nvme utility now (single TAB press
+should get you a completion with descriptions -- sadly, bash doesn't support
+descriptions within completions). If autocompletes disappear, just re-source
+_nvme and .zshrc. Also, make sure your .zshrc is ordered correctly: we want to
+source _nvme before updating our fpath. Both of these should occur before
+compinit is loaded.
+
+Updating NVMe Tab Autocompletions
+=================================
+
+zsh
+---
+
+Add your new command to the _cmds array in the following format:
+
+'command:short-form description'
+
+Add a case to the zsh case statement for autocompletion of subopts
+in the following format (as seen in _nvme):
+
+(bar)
+	local _list_of_subopts
+	_list_of_subopts=(
+	/dev/nvme':supply a device to use (required)'
+	--foo':do something cool'
+	-f':alias of --foo'
+	)
+
+	_arguments '*:: :->subcmds'
+	_describe -t commands "nvme bar options" _list_of_subopts
+	;;
+
+All zsh autocompletion built-ins start with _, and so should anything
+internal to your autocompletes. _arguments and _describe are built-ins.
+The '*:: :->subcmds' bit describes the format in which we want our
+options to be displayed (don't change this, unless you like pain.)
+_describe -t adds our list of options to the data structure associated with
+our command `bar'.
+
+Add the name of your command to the (help) case as well.
+
+Update your ~/.zsh/completion/_nvme with your new changes and re-source as needed.
+
+bash
+----
+
+Add the name of your command to _cmds in bash_nvme_completion.sh. Add a case to
+_nvme_list_opts in the following format:
+
+"bar")
+opts+="--foo= -f --baz= -b"
+;;
+
+Update your /etc/bash_completion.d/nvme version, and re-source things as needed.
+
+TO DO
+-----
+Automatically generate man pages and autocompletions for new NVMe commands, possibly
+with kerneldoc.

+nvmetests
+=========
+
+    This contains a NVMe tests framework. The purpose of this framework
+    to use nvme cli and test various supported commands and scenarios for
+    NVMe device.
+
+    In current implementation this framework uses nvme-cli to
+    interact with underlying controller/namespace.
+
+    Note these tests expect to run against real hardware and will
+    read and write data to /dev/nvme0!
+
+    DO NOT RUN THEM IF YOU DO NOT KNOW WHAT YOU ARE DOING!
+
+    You have been warned.
+
+1. Common Package Dependencies
+------------------------------
+
+    1. Python(>= 3.3)
+    2. nose2 (Installation guide http://nose2.readthedocs.io/)
+    3. flake8 (https://pypi.python.org/pypi/flake8)
+    4. mypy (https://pypi.org/project/mypy/)
+    5. autopep8 (https://pypi.org/project/autopep8/)
+    6. isort (https://pypi.org/project/isort/)
+
+    Python package management system pip can be used to install most of the
+    listed packages(https://pip.pypa.io/en/stable/installing/) :-
+    $ pip install nose2 flake8 mypy autopep8 isort
+
+2. Overview
+-----------
+
+    This framework follows simple class hierarchy. Each test file contains
+    one test. Each test is direct subclass or indirect subclass of TestNVMe
+    class which represents one testcase. To write a new testcase one can copy
+    existing template "nvme_simple_template_test.py" and start adding new
+    testcase specific functionality. For detailed information please look into
+    section 3.
+
+    For more information about tests, class hierarchy and code please refer :-
+
+    1. Documentation :- html/
+    2. Class Index :-  html/index.html
+    3. Class Hierarchy :- html/class-tree.html
+
+    For each testcase it will create log directory mentioned in
+    configuration file. This directory will be used for a temporary files
+    and storing execution logs of each testcases. Current implementation stores
+    stdout and stderr for each testcase under log directory, e.g. :-
+
+        $ tree nvmetests/
+        nvmetests/
+        ├── TestNVMeAttachDetachNSCmd
+        │   ├── stderr.log
+        │   └── stdout.log
+        ├── TestNVMeFlushCmd
+        │   ├── stderr.log
+        │   └── stdout.log
+        └── TestNVMeFormatCmd
+            ├── stderr.log
+            └── stdout.log
+                 .
+                 .
+                 .
+
+3. Walk-Through Example for writing a new testcase
+--------------------------------------------------
+    1. Copy simple test template file from current directory
+       with appropriate name, replace "simple_template" with testcase name
+       in new file name. Update config.json if necessary.
+    2. Write a testcase main function, make sure its name is starting with
+       test_*.
+    3. Based on the requirement one can inherit TestNVMe or TestNVMeIO
+       class.
+    4. Write test precondition code into setUp. Make sure you are calling
+       super class setUp.
+    5. Write test post condition code into tearDown. Make sure you are calling
+       super class tearDown.
+    6. Before writing a new function have a look into TestNVMe to see if it
+       can be reused.
+    7. Once testcase is ready make sure :-
+           a. Run flake8, mypy, autopep8 and isort on the testcase and fix
+	      errors/warnings.
+               - Example "$ ninja -C .build lint-python" will run flake8 and
+	         mypy on all the python files in current directory.
+	       - Example "$ ninja -C .build format-python" will run autopep8 and
+	         isort on all the python files in the current directory.
+
+4. Running testcases with framework
+-----------------------------------
+    1. Running single testcase (in the source tree) with nose2 :-
+       $ nose2 --verbose --start-dir tests nvme_writezeros_test

+nvmetests TODO List
+===================
+
+Feature list (with priority):-
+------------------------------
+    1. PRE and POST section improvements :-
+        a. Add functionality to load and unload driver.
+        b. Make sure default namespace is present, if not create one before
+           any test begins. Read the default namespace size from config file.
+    2. Add system statistics collection in PRE and POST section of testcase.
+    3. Create execution summary file under log directory at the end of each
+       run.
+    4. Add tracing functionality to track overall and current progress of the
+       testcase.
