From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> Same old work but now rebased and series ending with some DRM docs proposing the common specification which should enable nice common userspace tools to be written. For the moment I only have intel_gpu_top converted to use this and that seems to work okay. v2: * Added prototype of possible amdgpu changes and spec updates to align with the common spec. v3: * Documented that 'drm-driver' tag shall correspond with struct drm_driver.name. v4: * Dropped amdgpu conversion from the series for now until AMD folks can find some time to finish that patch.
