4Description:
5		The /sys/firmware/sgi_uv directory contains information
6		about the SGI UV platform.
7
8		Under that directory are a number of files:
9
10			partition_id
11			coherence_id
12
13		The partition_id entry contains the partition id.
14		SGI UV systems can be partitioned into multiple physical
15		machines, which each partition running a unique copy
16		of the operating system.  Each partition will have a unique
17		partition id.  To display the partition id, use the command:
18
19			cat /sys/firmware/sgi_uv/partition_id
20
21		The coherence_id entry contains the coherence id.
22		A partitioned SGI UV system can have one or more coherence
23		domain.  The coherence id indicates which coherence domain
24		this partition is in.  To display the coherence id, use the
25		command:
26
27			cat /sys/firmware/sgi_uv/coherence_id
