Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

Description:
|
|
The /sys/devices/system/memory contains a snapshot of the
|
|
internal state of the kernel memory blocks. Files could be
|
|
added or removed dynamically to represent hot-add/remove
|
|
operations.

Description:
|
|
The file /sys/devices/system/memory/memoryX/removable
|
|
indicates whether this memory block is removable or not.
|
|
This is useful for a user-level agent to determine
|
|
identify removable sections of the memory before attempting
|
|
potentially expensive hot-remove memory operation

Description:

The file /sys/devices/system/memory/memoryX/phys_device

is read-only and is designed to show the name of physical

memory device. Implementation is currently incomplete.

Description:
|
|
The file /sys/devices/system/memory/memoryX/phys_index

is read-only and contains the section ID in hexadecimal
|
|
which is equivalent to decimal X contained in the
|

memory section directory name.

Description:
|
|
The file /sys/devices/system/memory/memoryX/state
|
|
is read-write. When read, its contents show the
|
|
online/offline state of the memory section. When written,
|
|
root can toggle the the online/offline state of a removable
|
|
memory section (see removable file description above)
|
|
using the following commands.
|
|
# echo online > /sys/devices/system/memory/memoryX/state
|
|
# echo offline > /sys/devices/system/memory/memoryX/state
|
|
|
|
For example, if /sys/devices/system/memory/memory22/removable
|
|
contains a value of 1 and
|
|
/sys/devices/system/memory/memory22/state contains the
|
|
string "online" the following command can be executed by
|
|
by root to offline that section.
|
|
# echo offline > /sys/devices/system/memory/memory22/state
