Man1 - daxctl-list.1

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

  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

    # daxctl list --regions --devices

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

-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)"
    }
