4 Description:
5                 The /sys/firmware/sgi_uv directory contains information
6                 about the SGI UV platform.
8                 Under that directory are a number of files:
10                         partition_id
11                         coherence_id
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:
19                         cat /sys/firmware/sgi_uv/partition_id
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:
27                         cat /sys/firmware/sgi_uv/coherence_id
