+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
