Revert "drm/amdgpu: use GMC v9 KIQ workaround only for the GFXHUB" (v2)
With GFXOFF enabled, this patch will cause PCO amdgpu_test failed, but GFXOFF is necessary for PCO, so revert the patch. This reverts commit b83761bb0b09ec11c924afe9d88e458cb16a0372. v2: add a comment for future reference (Alex) Reviewed-by: Huang Rui <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Jack Gui <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
