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
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
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
