NAME

       daxctl-list - dump the platform Device-DAX regions, devices, and attributes in json.

SYNOPSIS

       daxctl list [<options>]

       Walk all the device-dax-regions in the system and list all device instances along with some of their
       major attributes.

       Options can be specified to limit the output to objects of a certain class. Where the classes are regions
       or devices. By default, daxctl list with no options is equivalent to:

       daxctl list --devices

EXAMPLE

           # daxctl list --regions --devices

           {
             "id":1,
             "devices":[
               {
                 "chardev":"dax1.0",
                 "size":3233808384
               }
             ]
           }

OPTIONS

       -r, --region=
           A device-dax region is a contiguous range of memory that hosts one or more /dev/daxX.Y devices, where
           X is the region id and Y is the device instance id. The keyword all can be specified to carry out the
           operation on every region in the system.

       -d, --dev=
           Specify a dax device name, <region id>.<instance id> tuple, or keyword all to filter the listing. For
           example to list the first device instance in region1:

           # daxctl list --dev=1.0

           {
             "chardev":"dax1.0",
             "size":3233808384
           }

       -D, --devices
           Include device-dax instance info in the listing (default)

       -M, --mappings
           Include device-dax instance mappings info in the listing

       -R, --regions
           Include region info in the listing

       -i, --idle
           Include idle (not enabled / zero-sized) devices in the listing

       -u, --human
           By default daxctl list will output machine-friendly raw-integer data. Instead, with this flag,
           numbers representing storage size will be formatted as human readable strings with units, other
           fields are converted to hexadecimal strings. Example:

           # daxctl list
           {
             "chardev":"dax1.0",
             "size":32828817408
           }

           # daxctl list --human
           {
             "chardev":"dax1.0",
             "size":"30.57 GiB (32.83 GB)"
           }
