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