Subject: [PATCH v3 0/4]  drm/amd: Add more GFXOFF stats for vangogh

This series adds new logging features for GFXOFF available for vangogh
and documentation for it.

I've created a small userspace program to interact with this new debugfs
interface and it can be found at: 

https://gitlab.freedesktop.org/andrealmeid/gfxoff_tool

Changelog:
 v3:
 - drop IP version check

 v2:
 - Make entrycount uint64_t
 - Add a note in docs about data types and overflow

André Almeida (4):
  drm/amd: Add detailed GFXOFF stats to debugfs
  drm/amd/pm: Implement GFXOFF's entry count and residency for vangogh
  Documentation/gpu: Document GFXOFF's count and residency
  drm/amdgpu: Document gfx_off members of struct amdgpu_gfx
