+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
