      drm/amdgpu/gfx9: fix driver reload with KIQ · 7b8d925d
      Alex Deucher 提交于
      Drop the KCQ disabling via KIQ.  We disable the MEC shortly
      after anyway, so there is no need to wait for all of this.
      Doing so seems to leave the MEC in a bad way.

      drm/amdgpu: Don't call amd_powerplay_destroy() if we don't have powerplay · 7bc7b777
      John Brooks 提交于
      amd_powerplay_destroy() expects a handle pointing to a struct pp_instance.
      On chips without PowerPlay, pp_handle points to a struct amdgpu_device. The
      resulting attempt to kfree() fields of the wrong struct ends in fire:
