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

38 -a <action>, --action=<action>
39 Commit Action: This field specifies the action that is taken on the
40 image downloaded with the Firmware Image Download command or on a
41 previously downloaded and placed image.
