What:		/sys/firmware/sgi_uv/
Date:		August 2008
Contact:	Russ Anderson <rja@sgi.com>
Description:
		The /sys/firmware/sgi_uv directory contains information
		about the SGI UV platform.

		Under that directory are a number of files:

			partition_id
			coherence_id

		The partition_id entry contains the partition id.
		SGI UV systems can be partitioned into multiple physical
		machines, which each partition running a unique copy
		of the operating system.  Each partition will have a unique
		partition id.  To display the partition id, use the command:

			cat /sys/firmware/sgi_uv/partition_id

		The coherence_id entry contains the coherence id.
		A partitioned SGI UV system can have one or more coherence
		domain.  The coherence id indicates which coherence domain
		this partition is in.  To display the coherence id, use the
		command:

			cat /sys/firmware/sgi_uv/coherence_id

msgmni
------

Maximum number of message queue ids on the system.
This value scales to the amount of lowmem. It is automatically recomputed
upon memory add/remove or ipc namespace creation/removal.
When a value is written into this file, msgmni's value becomes fixed, i.e. it
is not recomputed anymore when one of the above events occurs.
Use auto_msgmni to change this behavior.

auto_msgmni
-----------

Enables/Disables automatic recomputing of msgmni upon memory add/remove or

Echoing "1" into this file enables msgmni automatic recomputing.
Echoing "0" turns it off.
