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
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.
Specify a dax device name, . tuple, or keyword all to filter the listing. For example to list the first device instance in region1:
# daxctl list --dev=1.0
Include device−dax instance info in the listing (default)
Include region info in the listing
Include idle (not enabled / zero−sized) devices in the listing
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
# daxctl list --human
