NAME¶
daxctl-online-memory - Online the memory for a device that is in system-ram modeSYNOPSIS¶
daxctl online-memory <dax0.0> [<dax1.0>...<daxY.Z>] [<options>]
EXAMPLES¶
•Reconfigure dax0.0 to system-ram mode,
don’t online the memory
# daxctl reconfigure-device --mode=system-ram --no-online --human dax0.0 { "chardev":"dax0.0", "size":"7.87 GiB (8.45 GB)", "target_node":2, "mode":"system-ram" }
•Online the memory separately
# daxctl online-memory dax0.0 dax0.0: 62 new sections onlined onlined memory for 1 device
•Onlining memory when some sections were already
online
# daxctl online-memory dax0.0 dax0.0: 1 section already online dax0.0: 61 new sections onlined onlined memory for 1 device
DESCRIPTION¶
Online the memory sections associated with a device that has been converted to the system-ram mode. If one or more blocks are already online, print a message about them, and attempt to online the remaining blocks.This is complementary to the daxctl-reconfigure-device command, when used with the --no-online option to skip onlining memory sections immediately after the reconfigure. In these scenarios, the memory can be onlined at a later time using daxctl-online-memory.
OPTIONS¶
-r, --region=Restrict the operation to devices belonging to the
specified region(s). A device-dax region is a contiguous range of memory that
hosts one or more /dev/daxX.Y devices, where X is the region id and Y is the
device instance id.
--no-movable
--movable is the default. This can be overridden
to online new memory such that it is not movable. This allows any
allocation to potentially be served from this memory. This may preclude
subsequent removal. With the --movable behavior (which is default),
kernel allocations will not consider this memory, and it will be reserved for
application use.
-u, --human
By default the command will output machine-friendly
raw-integer data. Instead, with this flag, numbers representing storage size
will be formatted as human readable strings with units, other fields are
converted to hexadecimal strings.
-v, --verbose
Emit more debug messages
