| a1110654 | 2 | * Performance event support - hardware-specific disambiguation |

4 | * For now this is a compile-time decision, but eventually it should be |
| 5 | * runtime. This would allow multiplatform perf event support for e300 (fsl | |
| 6 | * embedded perf counters) plus server/classic, and would accommodate | |
| 7 | * devices other than the core which provide their own performance counters. | |
