I'm getting an error with gcc with this patch: CC [M] drivers/gpu/drm/amd/amdgpu/../display/dc/dcn21/dcn21_resource.o drivers/gpu/drm/amd/amdgpu/../display/dc/dcn21/dcn21_resource.c: In function ‘calculate_wm_set_for_vlevel’: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn21/dcn21_resource.c:964:22: error: SSE register return with SSE disabled
I checked again with gcc-8, but do not see that error message.
-CFLAGS_$(AMDDALPATH)/dc/dcn21/dcn21_resource.o := -mhard-float -msse -mpreferred-stack-boundary=4 +CFLAGS_$(AMDDALPATH)/dc/dcn21/dcn21_resource.o := -mhard-float -msse $(cc_stack_align)
Nothing should really change with regards to the -msse flag here, only the stack alignment flag changed. Maybe there was some other change in your Makefile that conflicts with my my patch?
