drm/amd/amdgpu: Add missing select_me_pipe_q() for gfx10 (ca9db7d1) · Commits · 戴 / test

The ability to select GFX GRBM me/pipe/queue/vmid was missing from the gfx10 driver. This patch adds it. Used by the debugfs register interface to select GFX resources when read/writing registers. Signed-off-by:
