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
