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)" }
