Description: Write an integer containing the size in bytes of the memory
|
||||
you want removed from each NUMA node to this file - it must be
|
||||
aligned to the memblock size. This amount of RAM will be removed
|
||||
from the kernel mappings and the following debugfs files will be
|
||||
created. This can only be successfully done once per boot. Once
|
||||
memory is successfully removed from each node, the following
|
||||
files are created.
|
||||
from each NUMA node in the kernel mappings and the following
|
||||
debugfs files will be created. Once memory is successfully
|
||||
removed from each node, the following files are created. To
|
||||
re-add memory to the kernel, echo 0 into this file (it will be
|
||||
automatically onlined).
|
||||
|
||||
What: /sys/kernel/debug/powerpc/memtrace/<node-id>
