| 15 | Description: Generic performance monitoring events |
| 16 | |
| 17 | A collection of performance monitoring events that may be |
| 18 | supported by many/most CPUs. These events can be monitored |
| 19 | using the 'perf(1)' tool. |
| 20 | |
| 21 | The contents of each file would look like: |
| 22 | |
| 23 | event=0xNNNN |
| 24 | |
| 25 | where 'N' is a hex digit and the number '0xNNNN' shows the |
| 26 | "raw code" for the perf event identified by the file's |
| 27 | "basename". |

| 44 | Description: POWER-systems specific performance monitoring events |
| 45 | |
| 46 | A collection of performance monitoring events that may be |
| 47 | supported by the POWER CPU. These events can be monitored |
| 48 | using the 'perf(1)' tool. |
| 49 | |
| 50 | These events may not be supported by other CPUs. |
| 51 | |
| 52 | The contents of each file would look like: |
| 53 | |
| 54 | event=0xNNNN |
| 55 | |
| 56 | where 'N' is a hex digit and the number '0xNNNN' shows the |
| 57 | "raw code" for the perf event identified by the file's |
| 58 | "basename". |
| 59 | |
| 60 | Further, multiple terms like 'event=0xNNNN' can be specified |
| 61 | and separated with comma. All available terms are defined in |
| 62 | the /sys/bus/event_source/devices/<dev>/format file. |
