drm/amdgpu: Fix oops when pp_funcs->switch_power_profile is unset

2018-12-01T08:37:28+00:00

commit 919a52fc4ca137c871f295224507fa3401e08472 upstream. On Vega20 and other pre-production GPUs, powerplay is not enabled yet. Check for NULL pointers before calling pp_funcs function pointers. Also affects Kaveri.

drm/amdkfd: Change the control stack MTYPE from UC to NC on GFX9

2018-09-20T15:25:17+00:00

CWSR fails on Raven if the control stack is MTYPE_UC, which is used for regular GART mappings. As a workaround we map it using MTYPE_NC. The MEC firmware expects the control stack at one page offset from the start of the MQD so it is part of the MQD allocation on GFXv9. AMDGPU added a memory allocation flag just for this purpose.

drm/amdgpu: allocate gart memory when it's required (v3)
