daxctl-list - Man Page

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)"
}
