This series adds support for Peak Tops Limiter (PTL) on AMD GFX 9.4.4
GPUs. PTL is a hardware feature that limits peak
computational throughput to stay within power and thermal constraints.
v1->v2:
- Rework patch set based on review feedback (Alex)
- Consolidate PTL structure and interface definitions
- Drop patches that have been merged into earlier patches
- Add explicit PSP response status check in psp_ptl_invoke()
- Add GFX idle wait before PTL state transition to prevent CP hang
- Unify refcount logic for PTL disable/enable
- Rework profiler IOCTL interface based on review feedback (James)
Benjamin Welton (1):
Add kfd_ioctl_profiler to contain profiler kernel driver changes
