^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) Description:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) The /sys/firmware/sgi_uv directory contains information
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) about the SGI UV platform.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) Under that directory are a number of files::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) partition_id
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) coherence_id
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) The partition_id entry contains the partition id.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) SGI UV systems can be partitioned into multiple physical
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) machines, which each partition running a unique copy
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) of the operating system. Each partition will have a unique
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) partition id. To display the partition id, use the command::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) cat /sys/firmware/sgi_uv/partition_id
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) The coherence_id entry contains the coherence id.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) A partitioned SGI UV system can have one or more coherence
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) domain. The coherence id indicates which coherence domain
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) this partition is in. To display the coherence id, use the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) command::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) cat /sys/firmware/sgi_uv/coherence_id
