+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
