drm/amdgpu: Correct the amdgpu_ucode_fini_bo place for Tonga

2018-03-14T19:38:25+00:00

The amdgpu_ucode_fini_bo should be called after gfx_v8_0_hw_fini, or it will have KCQ disable failed issue. For Tonga, as it firstly finishes SMC block, and the SMC hw fini will call amdgpu_ucode_fini, which will lead the amdgpu_ucode_fini_bo called before gfx_v8_0_hw_fini, this is incorrect.

If gfx_v8_0_hw_fini is called after amdgpu_ucode_fini_bo, we will hit KCQ disabled failed. Let amdgpu_ucode_fini_bo run after gfx_v8_0_hw_fini. BUG: SWDEV-135547 Reviewed-by: Rex Zhu Signed-off-by: Wang Hongcheng Signed-off-by: Alex Deucher
