drm/amd/amdgpu: Update update_config() logic

2020-05-12T12:40:06+00:00

[Why]
For MST case: when update_config is called to disable a stream,
this clears the settings for all the streams on that link.
We should only clear the settings for the stream that was disabled.

[How]
Clear the settings after the call to remove display is called.

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

2020-05-12T12:39:33+00:00

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/amd/display: add basic atomic check for cursor plane

2020-05-08T20:15:02+00:00

This patch adds a basic cursor check when an atomic test-only commit is
performed. The position and size of the cursor plane is checked.

This should fix user-space relying on atomic checks to assign buffers to
planes.

drm/amd/display: Fix vblank and pageflip event handling for FreeSync

2020-05-08T20:11:56+00:00

[Why]
We're sending the drm vblank event a frame too early in the case where
the pageflip happens close to VUPDATE and ends up blocking the signal.

The implementation in DM was previously correct *before* we started
sending vblank events from VSTARTUP unconditionally to handle cases
where HUBP was off, OTG was ON and userspace was still requesting some
DRM planes enabled. As part of that patch series we dropped VUPDATE
since it was deemed close enough to VSTARTUP, but there's a key
difference betweeen VSTARTUP and VUPDATE - the VUPDATE signal can be
blocked if we're holding the pipe lock.

There was a fix recently to revert the unconditional behavior for the
DCN VSTARTUP vblank event since it was sending the pageflip event on
the wrong frame - once again, due to blocking VUPDATE and having the
address start scanning out two frames later.

The problem with this fix is it didn't update the logic that calls
drm_crtc_handle_vblank(), so the timestamps are totally bogus now.

[How]
Essentially reverts most of the original VSTARTUP series but retains
the behavior to send back events when active planes == 0.

Some refactoring/cleanup was done to not have duplicated code in both
the handlers.

drm/amdgpu: Use GEM obj reference for KFD BOs

2020-05-08T18:44:12+00:00

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

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.
