NAME

       ndctl-update-firmware - update the firmware the given device

SYNOPSIS

       ndctl update-firmware <dimm> [<options>]

DESCRIPTION

       Provide a generic interface for updating NVDIMM firmware. The use of this depends on support for the
       NVDIMM "family" in libndctl, the kernel needs to enable that command set, and the device itself needs to
       implement the command. Use "ndctl list -DF" to interrogate if firmware update is enabled. For example:

       ndctl list -DFu -d nmem1
       {
         "dev":"nmem1",
         "id":"cdab-0a-07e0-ffffffff",
         "handle":"0",
         "phys_id":"0",
         "security":"disabled",
         "firmware":{
           "current_version":"0",
           "can_update":true
         }
       }

OPTIONS

       <dimm>
           A nmemX device name, or a dimm id number. Restrict the operation to the specified dimm(s). The
           keyword all can be specified to indicate the lack of any restriction, however this is the same as not
           supplying a --dimm option at all.

       -b, --bus=
           A bus id number, or a provider string (e.g. "ACPI.NFIT"). Restrict the operation to the specified
           bus(es). The keyword all can be specified to indicate the lack of any restriction, however this is
           the same as not supplying a --bus option at all.

       -f, --firmware
           firmware file used to perform the update

       -i, --force
           Ignore in-progress Address Range Scrub and try to submit the firmware update, or ignore firmware
           activate arm overflows and force-arm devices.

       -A, --arm
           Arm a device for firmware activation. This is enabled by default when a firmware image is specified.
           Specify --no-arm to disable this default. Otherwise, without a firmware image, this option can be
           used to manually arm a device for firmware activate.

       -D, --disarm
           Disarm devices after uploading the firmware file, or manually disarm devices when a firmware image is
           not specified. --no-disarm is not accepted.

       -v, --verbose
           Emit debug messages for the namespace check process.
