So, basically copying the config from radeon (cik.c; the num_pipe_configs == 16
case for my Hawaii) to amdgpu (gfx_v7_0.c) should do the trick if this is the
cause? Or are there other parts I'd need to change if I touch the tile
configuration? And: shouldn't modesetting hitting this as well, if it's a
kernel issue? Or does modesetting only use a reduced set of tiling
configurations?</pre>
