Date: August 2008

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
