[PATCH] drm/amdgpu: disallow gfxoff until GC IP blocks complete s2idle resume

2022-10-20 Thread Prike Liang
In the S2idle suspend/resume phase the gfxoff is keeping functional so some IP blocks will be likely to reinitialize at gfxoff entry and that will result in failing to program GC registers.Therefore, let disallow gfxoff until AMDGPU IPs reinitialized completely. Signed-off-by: Prike Liang --- dr
