[PATCH] drm/amdgpu: Fixed ras warning when uninstalling amdgpu

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  For the asic using smu v13_0_2, there is the following
warning when uninstalling amdgpu:
  amdgpu: ras disable gfx failed poison:1 ret:-22.

[Why]:
  For the asic using smu v13_0_2, the psp .suspend and
  mode1reset is called before amdgpu_ras_pre_fini during
  amdgpu uninstall, it has disabled all ras features and
  reset the psp. Since the psp is reset, calling
  amdgpu_ras_disable_all_features in amdgpu_ras_pre_fini
  to disable ras features will fail.

[How]:
  If all ras features are disabled, amdgpu_ras_disable_all_features
  will not be called to disable all ras features again.
