NAME

6       daxctl-list - dump the platform Device-DAX regions, devices, and
7       attributes in json.
8

SYNOPSIS

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

EXAMPLE

22           # daxctl list --regions --devices
23
24           {
25             "id":1,
26             "devices":[
27               {
28                 "chardev":"dax1.0",
29                 "size":3233808384
30               }
31             ]
32           }
33

OPTIONS

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       -M, --mappings
57           Include device-dax instance mappings info in the listing
58
59       -R, --regions
60           Include region info in the listing
61
62       -i, --idle
63           Include idle (not enabled / zero-sized) devices in the listing
64
65       -u, --human
66           By default daxctl list will output machine-friendly raw-integer
67           data. Instead, with this flag, numbers representing storage size
68           will be formatted as human readable strings with units, other
69           fields are converted to hexadecimal strings. Example:
70
71           # daxctl list
72           {
73             "chardev":"dax1.0",
74             "size":32828817408
75           }
76
77           # daxctl list --human
78           {
79             "chardev":"dax1.0",
80             "size":"30.57 GiB (32.83 GB)"
81           }
