31           # daxctl online-memory dax0.0
32           dax0.0: 62 new sections onlined
33           onlined memory for 1 device
34           .ft

40           .ft C
41           # daxctl online-memory dax0.0
42           dax0.0: 1 section already online
43           dax0.0: 61 new sections onlined
44           onlined memory for 1 device

DESCRIPTION

49       Online the memory sections associated with a device that has been
50       converted to the system-ram mode. If one or more blocks are already
51       online, print a message about them, and attempt to online the remaining
52       blocks.
53
54       This is complementary to the daxctl-reconfigure-device command, when
55       used with the --no-online option to skip onlining memory sections
56       immediately after the reconfigure. In these scenarios, the memory can
57       be onlined at a later time using daxctl-online-memory.
58

OPTIONS

60       -r, --region=
61           Restrict the operation to devices belonging to the specified
62           region(s). A device-dax region is a contiguous range of memory that
63           hosts one or more /dev/daxX.Y devices, where X is the region id and
64           Y is the device instance id.
65
66       --no-movable
67           --movable is the default. This can be overridden to online new
68           memory such that it is not movable. This allows any allocation to
69           potentially be served from this memory. This may preclude
70           subsequent removal. With the --movable behavior (which is default),
71           kernel allocations will not consider this memory, and it will be
72           reserved for application use.
73
74       -u, --human
75           By default the command will output machine-friendly raw-integer
76           data. Instead, with this flag, numbers representing storage size
77           will be formatted as human readable strings with units, other
78           fields are converted to hexadecimal strings.
79
80       -v, --verbose
81           Emit more debug messages
