drm/amd/display: polling vid stream status in hpo dp blank

2022-10-24T07:58:20+00:00

[ Upstream commit e32df0c7ecead95d70ca89f39b1b2b02a59ff691 ]

[why]
vid stream control is double bufferred, if we don't wait for video
stream enable set to 0, we may get temporary image corruption
showing on the stream when setting PIXEL_TO_SYMBOL_FIFO_ENABLE to 0.

drm/amd/display: Remove interface for periodic interrupt 1

2022-10-24T07:58:20+00:00

[ Upstream commit 97d8d6f075bd8f988589be02b91f6fa644d0b0b8 ]

[why]
Only a single VLINE interrupt is available so interface should not
expose the second one which is used by DMU firmware.

[how]
Remove references to periodic_interrupt1 and VLINE1 from DC interfaces.

drm/amd/display: correct hostvm flag

[ Upstream commit 796d6a37ff5ffaf9f2dc0f3f4bf9f4a1034c00de ]

[Why]
Hostvm should be enabled/disabled accordding to
the status of riommu_active, but hostvm always
be disabled on DCN31 which causes underflow

[How]
Set correct hostvm flag on DCN31

drm/amd/display: fix overflow on MIN_I64 definition

2022-10-24T07:58:17+00:00

[ Upstream commit 6ae0632d17759852c07e2d1e0a31c728eb6ba246 ]

The definition of MIN_I64 in bw_fixed.c can cause gcc to whinge about
integer overflow, because it is treated as a positive value, which is
then negated. The temporary positive value is not necessarily
representable.

This causes the following warning:
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/calcs/bw_fixed.c:30:19:
warning: integer overflow in expression ‘-9223372036854775808’ of type
‘long long int’ results in ‘-9223372036854775808’ [-Woverflow]
  30 |         (int64_t)(-(1LL << 63))
     |                   ^

Writing out (-MAX_I64 - 1) works instead.

drm/amd/display: Fix DP MST timeslot issue when fallback happened

2022-10-12T07:51:25+00:00

[ Upstream commit 20c6168b3c8aadef7d2853c925d99eb546bd5e1c ]

[Why]
When USB4 DP link training failed and fell back to lower link rate,
the time slot calculation uses the verified_link_cap.
And the verified_link_cap was not updated to the new one.
It caused the wrong VC payload time-slot was allocated.

[How]
Updated verified_link_cap with the new one from cur_link_settings
after the LT completes successfully.

drm/amd/display: skip audio setup when audio stream is enabled

[ Upstream commit 65fbfb02c2734cacffec5e3f492e1b4f1dabcf98 ]

[why]
We have minimal pipe split transition method to avoid pipe
allocation outage.However, this method will invoke audio setup
which cause audio output stuck once pipe reallocate.

[how]
skip audio setup for pipelines which audio stream has been enabled

[ Upstream commit 52bb21499cf54fa65b56d97cd0d68579c90207dd ]

[Why]
The desktop plane and full-screen game plane may have different
gamut remap coefficients, if switching between desktop and
full-screen game without updating the gamut remap will cause
incorrect color.

drm/amd/display: Assume an LTTPR is always present on fixed_vs links

[ Upstream commit 29956d0fded036a570bd8e7d4ea4b1a1730307d2 ]

[WHY]
LTTPRs can in very rare instsances fail to increment DPCD LTTPR count.
This results in aux-i LTTPR requests to be sent to the wrong DPCD
address, which causes link training failure.

[HOW]
Override internal repeater count if fixed_vs flag is set for a given link
