f6fe4053b9 drm/amd/display: Use a temporary copy of the current state when updating DSC config
[why]
When updating DSC config, a new config has to be validated before proceeding
with applying the update. Validation, however, modifies the current state.
This means DSC config validation would affect pipe re-assignment, causing
intermittent screen corruption issues when ODM is required for DSC.

[how]
- Use a copy of the current state for modified DSC config validation
- Set the update type to FULL_UPDATE to correctly validate and set the
  actual state used for committing the streams

a6e4da40bd drm/amd/display: Spin for DMCUB PHY init in DC
[Why]
DCN will hang if we access registers before PHY init is done.

So we need to spin or abort.

[How]
On hardware with DMCUB running and working we shouldn't time out
waiting for this to finish and we shouldn't hit the spin cycle.

If there's no hardware support then we should exit out of the function
early assuming that PHY init was already done elsewhere.

If we hit the timeout then there's likely a bug in firmware or software
and we need to debug - add errors and asserts as appropriate.

b9fe515105 drm/amd/display: DML Validation Dump/Check with Logging
[Why]
Need validation that we are programming the expected values (rq, ttu, dlg)
from DML. This debug feature will output logs if we are programming
incorrect values and may help differentiate DAL issues from HW issues.

[How]
Dump relevant registers for each pipe with active stream. Compare current
reg values with the converted DML output. Log mismatches when found.

78c7738211 drm/amd/display: cleanup of function pointer tables
[Why]
It is becoming increasingly hard to figure out which
function is called on the different DCN versions

[How]
1. Make function pointer table init in its own init.c file
2. Remove other scenarios in hwseq.c file that need to
include headers of other DCN versions. (If needed,
it should have been done via the function pointers)

56fc13fe6c drm/amd/display: Don't spin forever waiting for DMCUB phy/auto init
[Why]
It's an interface violation to use infinite loops within DMUB
service functions and we'll lock up the kernel by doing so.

Revert the function back to its intended functionality.

46250a0cba drm/amd/display: Avoid conflict between HDR multiplier and 3dlut
[WHY]
There can be a conflict between OS HDR multiplier and 3dlut HDR
multiplier, which are both sent to DC.

[HOW]
Instead of having dc determine which HDR multiplier to use, make the
decision in dm and send only the intended value in a surface update.
Store the current OS HDR multiplier and determine whether to use it or
the 3dlut's multiplier before sending the surface update to dc. Send
multiplier to dc in fixed31_32 format, dc then converts it to hw format.

[Why]
There is a case where the margin is between 50 and 60, but applying the

8d8a6af71a drm/amd/display: Fix stereo with DCC enabled
[Why]
When sending DCC with Stereo, DCC gets enabled but the meta addresses
are 0. This happens momentarily before the meta addresses are populated
with a valid address.

[How]
Add call validate_dcc_with_meta_address() in
copy_surface_update_to_plane() to check for surface address and DCC
change.
When DCC has changed, check if DCC enable is true but meta address is 0.
If so, we turn DCC enable to false. When surface address has changed, we
check if DCC enable is false but meta address is not 0. If so, we turn
DCC enable back to true.  This will restore DCC enable to the proper
setting once the meta address is valid.

903e859b72 drm/amd/display: check for dp rev before reading lttpr regs
[Why]
LTTPR was introduced after DP1.2. Reading LTTPR registers 0xFXXXX
on some DP 1.2 display is causing an unexpected behavior.

[How]
Make sure that we don't read any lttpr registers on 1.2 displays.

00ada9d14f drm/amd/display: Unify all scaling when Integer Scaling enabled
[why]
We want to guarantee integer ratio scaling for all scaling modes.

[how]
Treat centered, fullscreen, preserve aspect ratio the same: scale
the view as many times as possible, and fill in the rest with a black
border.

ae8cf9774e drm/amd/display: Add some hardware status in DTN log debugfs
[Why]
For debug purpose, we need to check the following hardware status
in DTN log debugfs:
1.dpp & hubp clock enable;
2.crtc blank enable;
3.link phy status;

[How]
Add the upper information in the amdgpu_dm_dtn_log debugfs.

For CRTC blanked status, since DCN2 and greater reports it on the OPP
instead of OTG, we patch it in after calling optc1_read_otg_states.
Ideally, this should be done in the DCN version specific function hooks.
It has been left as a TODO item.

f2988e6714 drm/amd/display: optimize bandwidth after commit streams.
[Why]
System is unable to enter S0i3 due to DISPLAY_OFF_MASK not asserted
in SMU.

[How]
Optimized bandwidth should be called paired and to resolve unplug
display underflow issue, optimize bandwidth after commit streams is
moved to next page flip, in case of S0i3, there is a change for no
flip coming causing display count is 1 in SMU side.
Add optimize bandwidth after commit stream.

[WHY]
It has been a useful option in debugging GFXOFF and P.State Change issues.
May be required as for platform specific workaround.

[HOW]
Create option in enum dc_debug_options, "disable_vactive_clock_change".
When it is set, dm_dram_clock_change_vactive, will translate into

5ed78cd69a drm/amd/display: set MSA MISC1 bit 6 while sending colorimetry in VSC SDP
[Why]
It is confusing to sinks if we send VSC SDP only on some format. Today we
signal colorimetry format using MSA while in formats like sRGB.
But when we switch to BT2020 we set the bit to ignore MSA  colorimetry and
instead use the colorimetry information in the VSC SDP.

But if sink supports signaling of colorimetry via VSC SDP we should always
set the MSA MISC1 bit 6, instead of doing so selectively.

[How]
If sink supports signaling of colorimetry via VSC SDP, and we are sending
the colorimetry info via VSC SDP with packet revision 05h, then always
set MSA MISC1 bit 6.

a5132f9728 drm/amd/display: Add a sanity check for DSC already enabled/disabled
[why]
If acquire/release DSC resource sequence is affected by a regression,
it can happen that the already-in-use DSC HW block is being wrongly
re-used for a different pipe. The reverse is also possible, i.e.
already-disabled DSC HW block could be disabled from other context.

[how]
Read back the enable state of DSC HW and report an error if duplicate
enable or disable was attempted.

[WHY]
Currently made a change where disable_output is called using signal_type.
Using actual signal_type when calilng disable_output in power_down_encoders
would make DP to HDMI dongle not light up on boot. As it would have signal_type
SIGNAL_TYPE_DISPLAY_PORT.

[HOW]
Set signal_type to SIGNAL_TYPE_NONE unless it is eDP.

For unknown reason, immediate flip with host VM translation on NV12
surface will underflow on last row of PTE.

[How]
Hack chroma viewport height to make fetch one more row of PTE.
Note that this will cause hubp underflow on all video underlay
cases, but the underflow is not user visible since it is in
blank region.
