.SH "NAME"
nvme-intel-id-ctrl \- Send NVMe Identify Controller, return result and structure
.SH "SYNOPSIS"
.sp
.nf
\fInvme intel id\-ctrl\fR <device> [\-\-vendor\-specific | \-v] [\-\-raw\-binary | \-b]
                        [\-\-output\-format=<fmt> | \-o <fmt>]
.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\&.
.sp
If having the program decode the output for readability, this version will decode Intel vendor unique portions of the structure\&.
.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 <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fIjson\fR, or
\fIbinary\fR\&. Only one output format can be used at a time\&.
