1 What: /sys/devices/system/memory
5 The /sys/devices/system/memory contains a snapshot of the
6 internal state of the kernel memory blocks. Files could be
9 Users: hotplug memory add/remove tools
12 What: /sys/devices/system/memory/memoryX/removable
16 The file /sys/devices/system/memory/memoryX/removable is a
17 legacy interface used to indicated whether a memory block is
19 "1" if and only if the kernel supports memory offlining.

24 What: /sys/devices/system/memory/memoryX/phys_device
28 The file /sys/devices/system/memory/memoryX/phys_device
33 What: /sys/devices/system/memory/memoryX/phys_index
37 The file /sys/devices/system/memory/memoryX/phys_index
40 memory section directory name.
42 What: /sys/devices/system/memory/memoryX/state
46 The file /sys/devices/system/memory/memoryX/state
48 state of the memory block. When written, root can toggle
49 the online/offline state of a memory block using the following
52 # echo online > /sys/devices/system/memory/memoryX/state
53 # echo offline > /sys/devices/system/memory/memoryX/state

70 What: /sys/devices/system/memory/memoryX/valid_zones
74 The file /sys/devices/system/memory/memoryX/valid_zones is
77 For online memory blocks, it returns in which zone memory
78 provided by a memory block is managed. If multiple zones
79 apply (not applicable for hotplugged memory), "None" is returned
80 and the memory block cannot be offlined.
82 For offline memory blocks, it returns by which zone memory
83 provided by a memory block can be managed when onlining.
85 the state of an offline memory block to "online". Only one of

99 /sys/devices/system/memory/memory9/node0 -> ../../node/node0
108 points to the corresponding /sys/devices/system/memory/memoryY
109 memory section directory. For example, the following symbolic
110 link is created for memory section 9 on node0.
