| 26 | * Core Mesa support for the AMD_performance_monitor extension. |
| 27 | * |
| 28 | * In order to implement this extension, start by defining two enums: |
| 29 | * one for Groups, and one for Counters. These will be used as indexes into |
| 30 | * arrays, so they should start at 0 and increment from there. |
| 31 | * |
| 32 | * Counter IDs need to be globally unique. That is, you can't have counter 7 |
| 33 | * in group A and counter 7 in group B. A global enum of all available |
| 34 | * counters is a convenient way to guarantee this. |
