| Description: Generic performance monitoring events |
| |
| A collection of performance monitoring events that may be |
| supported by many/most CPUs. These events can be monitored |
| using the 'perf(1)' tool. |
| |
| The contents of each file would look like: |
| |
| event=0xNNNN |
| |
| where 'N' is a hex digit and the number '0xNNNN' shows the |
| "raw code" for the perf event identified by the file's |
| "basename". |

| Description: POWER-systems specific performance monitoring events |
| |
| A collection of performance monitoring events that may be |
| supported by the POWER CPU. These events can be monitored |
| using the 'perf(1)' tool. |
| |
| These events may not be supported by other CPUs. |
| |
| The contents of each file would look like: |
| |
| event=0xNNNN |
| |
| where 'N' is a hex digit and the number '0xNNNN' shows the |
| "raw code" for the perf event identified by the file's |
| "basename". |
| |
| Further, multiple terms like 'event=0xNNNN' can be specified |
| and separated with comma. All available terms are defined in |
| the /sys/bus/event_source/devices/<dev>/format file. |
