NAME
       nvme-feat-power-mgmt - Get and set power management feature

SYNOPSIS
       nvme [<global-options>] feat power-mgmt <device>
                               [--ps=<ps> | -p <ps>] [--wh=<wh> | -w <wh>]
                               [--sel=<select> | -S <select>] [--save | -s]

DESCRIPTION
       Get and set power management feature.

       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 setting option (--ps) is specified, the command will update the
       power management configuration. If the --ps option is omitted, it will
       retrieve and display the current configuration.

       On success it returns 0, error code otherwise.

OPTIONS
       -p <ps>, --ps=<ps>
           Power state. Specifies the power state to transition the controller
           to.

       -w <wh>, --wh=<wh>
           Workload hint. Provides a hint to the controller about the workload
           characteristics.

       -S <select>, --sel=<select>
           Select (SEL): This field specifies which value of the attributes to
           return in the provided data:

       -s, --save
           Save the attribute so that it persists through all power states and
           resets.

GLOBAL OPTIONS
       The following options are defined at the top-level nvme command and are
       available to this subcommand:

       --dry-run
           Print the command that would be executed, but do not actually
           execute it.

       --no-ioctl-probing
           Disable probing for 64-bit IOCTL support.

       --no-retries
           Disable retry logic on transient errors.

       -o <fmt>, --output-format=<fmt>
           Set the reporting format to normal, tabular, 'json, or binary. Only
           one output format may be used at a time.

       --output-format-version=<version>
           Select the output format version. Version 1 uses the original field
           naming, while version 2 (default) provides more consistent and
           script-friendly field names.

       --timeout=<ms>
           Set the timeout for the command in milliseconds.

       -v, --verbose
           Increase the level of detail in the output. May be specified
           multiple times to further increase verbosity.

       These options can also be set as machine-wide defaults in
       nvme-cli.conf(5). A command-line flag always overrides the file.

EXAMPLES
       o   Has the program issue a feat power-mgmt to get the current
           configuration:

               # nvme feat power-mgmt /dev/nvme0

       o   Has the program issue a feat power-mgmt to set power state and
           workload hint:

               # nvme feat power-mgmt /dev/nvme0 --ps=1 --wh=2 --save
