[PATCH v2 00/13] drm/amdgpu: Add Peak Tops Limiter (PTL)

[Perry Yuan <perry.yuan@amd.com>]

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
