drm/amdgpu: Use GEM obj reference for KFD BOs

2020-06-03T06:23:04+00:00

[ Upstream commit 39b3128d7ffd44e400e581e6f49e88cb42bef9a1 ]

Releasing the AMDGPU BO ref directly leads to problems when BOs were
exported as DMA bufs. Releasing the GEM reference makes sure that the
AMDGPU/TTM BO is not freed too early.

Also take a GEM reference when importing BOs from DMABufs to keep
references to imported BOs balances properly.

drm/amdgpu: drop unnecessary cancel_delayed_work_sync on PG ungate

2020-06-03T06:23:03+00:00

[ Upstream commit 1fe48ec08d9f2e26d893a6c05bd6c99a3490f9ef ]

As this is already properly handled in amdgpu_gfx_off_ctrl(). In fact,
this unnecessary cancel_delayed_work_sync may leave a small time window
for race condition and is dangerous.

drm/amd/amdgpu: add raven1 part to the gfxoff quirk list

2020-05-20T06:22:29+00:00

commit 975f543e7522e17b8a4bf34d7daeac44819aee5a upstream.

On my raven1 system (rev c6) with VBIOS 113-RAVEN-114 GFXOFF is
not stable (resulting in large block tiling noise in some applications).

Disabling GFXOFF via the quirk list fixes the problems for me.

drm/amdgpu: force fbdev into vram

2020-05-20T06:22:17+00:00

[ Upstream commit a6aacb2b26e85aa619cf0c6f98d0ca77314cd2a1 ]

We set the fb smem pointer to the offset into the BAR, so keep
the fbdev bo in vram.

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

2020-05-14T05:59:13+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

2020-05-14T05:59:12+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.
