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 .ft C
23 # daxctl list --regions --devices
24
25 {
26 "id":1,
27 "devices":[
28 {
29 "chardev":"dax1.0",
30 "size":3233808384
31 }
32 ]
33 }
34 .ft
35
36
38 -r, --region=
39 A device-dax region is a contiguous range of memory that hosts one
40 or more /dev/daxX.Y devices, where X is the region id and Y is the
41 device instance id. The keyword all can be specified to carry out
42 the operation on every region in the system.
43
44 -d, --dev=
45 Specify a dax device name, <region id>.<instance id> tuple, or
46 keyword all to filter the listing. For example to list the first
47 device instance in region1:
48
49
50 .ft C
51 # daxctl list --dev=1.0
52
53 {
54 "chardev":"dax1.0",
55 "size":3233808384
56 }
57 .ft
58
59
60 -D, --devices
61 Include device-dax instance info in the listing (default)
62
63 -M, --mappings
64 Include device-dax instance mappings info in the listing
65
66 -R, --regions
67 Include region info in the listing
68
69 -i, --idle
70 Include idle (not enabled / zero-sized) devices in the listing
71
72 -u, --human
73 By default daxctl list will output machine-friendly raw-integer
74 data. Instead, with this flag, numbers representing storage size
75 will be formatted as human readable strings with units, other
76 fields are converted to hexadecimal strings. Example:
77
78
79 .ft C
80 # daxctl list
81 {
82 "chardev":"dax1.0",
83 "size":32828817408
84 }
85
86 # daxctl list --human
87 {
88 "chardev":"dax1.0",
89 "size":"30.57 GiB (32.83 GB)"
90 }
