drm/amdgpu: drop redundant cg/pg ungate on runpm enter

2020-05-14T05:58:19+00:00

[ Upstream commit f7b52890daba570bc8162d43c96b5583bbdd4edd ] CG/PG ungate is already performed in ip_suspend_phase1. Otherwise, the CG/PG ungate will be performed twice. That will cause gfxoff disablement is performed twice also on runpm enter while gfxoff enablemnt once on rump exit. That will put gfxoff into disabled state.

drm/amdgpu: move kfd suspend after ip_suspend_phase1

2020-05-14T05:58:19+00:00

[ Upstream commit c457a273e118bb96e1db8d1825f313e6cafe4258 ] This sequence change should be safe as what did in ip_suspend_phase1 is to suspend DCE only. And this is a prerequisite for coming redundant cg/pg ungate dropping.

drm/amdgpu: fix the hw hang during perform system reboot and reset

commit b2a7e9735ab2864330be9d00d7f38c961c28de5d upstream. The system reboot failed as some IP blocks enter power gate before perform hw resource destory. Meanwhile use unify interface to set device CGPG to ungate state can simplify the amdgpu poweroff or reset ungate guard.

[ Upstream commit 487eca11a321ef33bcf4ca5adb3c0c4954db1b58 ] The system will be hang up during S3 suspend because of SMU is pending for GC not respose the register CP_HQD_ACTIVE access request.This issue root cause of accessing the GC register under enter GFX CGGPG and can be fixed by disable GFX CGPG before perform suspend. v2: Use disable the GFX CGPG instead of RLC safe mode guard.

drm/amdgpu: fix KIQ ring test fail in TDR of SRIOV

2020-02-24T07:36:38+00:00

[ Upstream commit 5a7489a7e189ee2be889485f90c8cf24ea4b9a40 ] issues: MEC is ruined by the amdkfd_pre_reset after VF FLR done fix: amdkfd_pre_reset() would ruin MEC after hypervisor finished the VF FLR, the correct sequence is do amdkfd_pre_reset before VF FLR but there is a limitation to block this sequence: if we do pre_reset() before VF FLR, it would go KIQ way to do register access and stuck there, because KIQ probably won't work by that time (e.g. you already made GFX hang) so the best way right now is to simply remove it.
