There is also interrupt handling code in SDMA 5.0 and 5.2 which appears to be using it, but is is unreachable since nothing ever allocates the relevant IDR. We replace those with one time warnings just to avoid any functional difference, but it is also possible they should be removed. v2: also fix up gfx_v12_1.c and sdma_v7_1.c Signed-off-by: Tvrtko Ursulin References: cb17fff3a254 ("drm/amdgpu/mes: remove unused functions") Cc: Alex Deucher Reviewed-by: Christian König Signed-off-by: Christian König Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c index 6e19836c5ff6..0d4c77c1b4b5 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c @@ -115,9 +115,6 @@ int amdgpu_mes_init(struct amdgpu_device *adev) adev->mes.adev = adev;
