drm/i915: fix port checks for MST support on gen >= 11

2020-06-07T11:18:48+00:00

[ Upstream commit 10d987fd1b7baceaafa78d805e71427ab735b4e4 ]

Both Ice Lake and Elkhart Lake (gen 11) support MST on all external
connections except DDI A. Tiger Lake (gen 12) supports on all external
connections.

Move the check to happen inside intel_dp_mst_encoder_init() and add
specific platform checks.

drm/amd/display: drop cursor position check in atomic test

2020-06-03T06:21:25+00:00

[ Upstream commit f7d5991b92ff824798693ddf231cf814c9d5a88b ]

get_cursor_position already handles the case where the cursor has
negative off-screen coordinates by not setting
dc_cursor_position.enabled.

gpu/drm: Ingenic: Fix opaque pointer casted to wrong type

2020-06-03T06:21:19+00:00

[ Upstream commit abf56fadf0e208abfb13ad1ac0094416058da0ad ]

The opaque pointer passed to the IRQ handler is a pointer to the
drm_device, not a pointer to our ingenic_drm structure.

It still worked, because our ingenic_drm structure contains the
drm_device as its first field, so the pointer received had the same
value, but this was not semantically correct.

drm/amdgpu: Use GEM obj reference for KFD BOs

2020-06-03T06:21:11+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.

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/i915/gvt: Init DPLL/DDI vreg for virtual display instead of inheritance.

2020-05-27T15:46:43+00:00

commit f965b68188ab59a40a421ced1b05a2fea638465c upstream.

Init value of some display vregs rea inherited from host pregs. When
host display in different status, i.e. all monitors unpluged, different
display configurations, etc., GVT virtual display setup don't consistent
thus may lead to guest driver consider display goes malfunctional.

The added init vreg values are based on PRMs and fixed by calcuation
from current configuration (only PIPE_A) and the virtual EDID.
