NAME

6       daxctl-online-memory - Online the memory for a device that is in
7       system-ram mode
8

SYNOPSIS

10       daxctl online-memory <dax0.0> [<dax1.0>...<daxY.Z>] [<options>]
11

EXAMPLES

13       •   Reconfigure dax0.0 to system-ram mode, don’t online the memory
14
15           # daxctl reconfigure-device --mode=system-ram --no-online --human dax0.0
16           {
17             "chardev":"dax0.0",
18             "size":"7.87 GiB (8.45 GB)",
19             "target_node":2,
20             "mode":"system-ram"
21           }
22
23       •   Online the memory separately
24
25           # daxctl online-memory dax0.0
26           dax0.0: 62 new sections onlined
27           onlined memory for 1 device
28
29       •   Onlining memory when some sections were already online
30
31           # daxctl online-memory dax0.0
32           dax0.0: 1 section already online
33           dax0.0: 61 new sections onlined
34           onlined memory for 1 device
35

DESCRIPTION

37       Online the memory sections associated with a device that has been
38       converted to the system-ram mode. If one or more blocks are already
39       online, print a message about them, and attempt to online the remaining
40       blocks.
41
42       This is complementary to the daxctl-reconfigure-device command, when
43       used with the --no-online option to skip onlining memory sections
44       immediately after the reconfigure. In these scenarios, the memory can
45       be onlined at a later time using daxctl-online-memory.
46

OPTIONS

48       -r, --region=
49           Restrict the operation to devices belonging to the specified
50           region(s). A device-dax region is a contiguous range of memory that
51           hosts one or more /dev/daxX.Y devices, where X is the region id and
52           Y is the device instance id.
53
54       --no-movable
55           --movable is the default. This can be overridden to online new
56           memory such that it is not movable. This allows any allocation to
57           potentially be served from this memory. This may preclude
58           subsequent removal. With the --movable behavior (which is default),
59           kernel allocations will not consider this memory, and it will be
60           reserved for application use.
61
62       -u, --human
63           By default the command 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.
67
68       -v, --verbose
69           Emit more debug messages
