What: /sys/firmware/sgi_uv/

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
