Hi Stephen/Michael,

I made this fix:

Could you check if it fixes the issue for you? If so, could you undo your revert?

Thanks
Siqueira

Hi all,

After merging the amdgpu tree, today's linux-next build (powerpc
allyesconfig) failed like this:

ld: drivers/gpu/drm/amd/display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o uses soft float
ld: failed to merge target specific data of file drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o

I have reverted commit

c653c591789b ("drm/amdgpu: Re-enable DCN for 64-bit powerpc")

for today.

It bisects to:

40b31e5355ba ("drm/amd/display: Remove FPU flags from DCN30 Makefile")

So I guess there's still some float code in dcn30?

cheers
