6 daxctl-list - dump the platform Device-DAX regions, devices, and
7 attributes in json.
8
10 daxctl list [<options>]
11
12 Walk all the device-dax-regions in the system and list all device
13 instances along with some of their major attributes.
14
15 Options can be specified to limit the output to objects of a certain
16 class. Where the classes are regions or devices. By default, daxctl
17 list with no options is equivalent to:
18
19 daxctl list --devices
20
22 # daxctl list --regions --devices
23
24 {
25 "id":1,
26 "devices":[
27 {
28 "chardev":"dax1.0",
29 "size":3233808384
30 }
31 ]
32 }
33
35 -r, --region=
36 A device-dax region is a contiguous range of memory that hosts one
37 or more /dev/daxX.Y devices, where X is the region id and Y is the
38 device instance id. The keyword all can be specified to carry out
39 the operation on every region in the system.
40
41 -d, --dev=
42 Specify a dax device name, <region id>.<instance id> tuple, or
43 keyword all to filter the listing. For example to list the first
44 device instance in region1:
45
46 # daxctl list --dev=1.0
47
48 {
49 "chardev":"dax1.0",
50 "size":3233808384
51 }
52
53 -D, --devices
54 Include device-dax instance info in the listing (default)
55
56 -R, --regions
57 Include region info in the listing
58
59 -i, --idle
60 Include idle (not enabled / zero-sized) devices in the listing
61
62 -u, --human
63 By default daxctl list will output machine-friendly raw-integer
64 data. Instead, with this flag, numbers representing storage size
65 will be formatted as human readable strings with units, other
66 fields are converted to hexadecimal strings. Example:
67
68 # daxctl list
69 {
70 "chardev":"dax1.0",
71 "size":32828817408
72 }
73
74 # daxctl list --human
75 {
76 "chardev":"dax1.0",
77 "size":"30.57 GiB (32.83 GB)"
78 }
