.SH "NAME"
nvme-fw-commit \- Used to verify and commit a firmware image\&.
.SH "SYNOPSIS"
.sp
.nf
\fInvme fw\-commit\fR <device> [\-\-slot=<slot> | \-s <slot>]
[\-\-action=<action> | \-a <action>]
[\-\-bpid=<boot\-partid> | \-b <boot\-partid> ]
.fi
.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\&.
.SH "OPTIONS"
.PP
\-a <action>, \-\-action=<action>
.RS 4
Commit Action: This field specifies the action that is taken on the image downloaded with the Firmware Image Download command or on a previously downloaded and placed image\&.
