9119e993cf drm/amd/display: Handle potential dpp_inst mismatch with pipe_idx
[Why]
In some pipe harvesting configs, we will select the incorrect
dpp_inst when programming DTO. This is because when any intermediate
pipe is fused, resource instances are no longer in 1:1
correspondence with pipe index.

[How]
When looping through pipes to program DTO, get the dpp_inst
associated with each pipe from res_pool.

98ad74c6a9 drm/amd/display: Handle pixel format test request
[Why]
Some DSC tests fail because stream pixel encoding does not change
its value according to the type requested in the DPCD test params.

[How]
Set stream pixel encoding before updating DSC config and configuring
the test pattern.

c31bef1cb1 drm/amd/display: Fix clock table filling logic
[Why]
Currently, the code that fills the clock table can miss filling
information about some of the higher voltage states advertised
by the SMU. This, in turn, may cause some of the higher pixel clock
modes (e.g. 8k60) to fail validation.

[How]
Fill the table with one entry per DCFCLK level instead of one entry
per FCLK level. This is needed because the maximum FCLK does not
necessarily need maximum voltage, whereas DCFCLK values from SMU
cover the full voltage range.

2. update dpcd_set_training_pattern to take in dc_dp_training_pattern

4469201b19 drm/amd/display: DETBufferSizeInKbyte variable type modifications
[Why]
DETBufferSizeInKByte is not expected to be sub-dividable, hence
unsigned int is a better suited data-type. Change it to an array
as well to satisfy current requirements.

[How]
Change the data-type of DETBufferSizeInKByte to an unsigned int
array. Modify the all the variables like DETBufferSizeY,
DETBufferSizeC that are involved in DETBufferSizeInKByte calculations

8225367130 drm/amd/display: Add fallback and abort paths for DP link training.
[Why]
When enabling a DisplayPort stream:
- Optionally reducing link bandwidth between failed link training
attempts should progressively relax training requirements.
- Abandoning link training altogether if a sink is unplugged should
avoid unnecessary training attempts.

[How]
- Add fallback parameter to DP link training function and reduce link
bandwidth between failed training attempts as long as stream bandwidth
requirements are met.
- Add training status for sink unplug and abort training when this
status is reported.

81927e2808 drm/amd/display: Support for DMUB AUX
[WHY]
To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes.

[How]
1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands
   to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd
   with DCN and sends reply back in an outbox1 message triggering an
   outbox1 interrupt to driver.
2) In existing driver implementation, AUX commands are processed
   synchronously by configuring DCN reg. But in DMUB AUX, driver sends an
   inbox1 message and waits for a conditional variable (CV) which will be
   signaled by outbox1 ISR.
3) DM will retrieve Outbox1 message and send back reply to upper layer
   and complete the AUX command

As hardware team suggested that we need to add a max dsc bw overhead
into existing stream bandwidth when DSC is used.
The formula as below:

max_dsc_bw_overhead =
v_addressable * slice_count * 256 bit * pixel clock / v_total / h_total

effective stream bandwidth = pixel clock * bpp

stream bandwidth = effective stream bandwidth + dsc stream overhead

9c82354e89 drm/amd/display: treat memory as a single-channel for asymmetric memory v2
Previous change had been reverted since it caused hang.
Remake change to avoid defect.

[Why]
1. Driver use umachannelnumber to calculate watermarks for stutter.
In asymmetric memory config, the actual bandwidth is less than
dual-channel. The bandwidth should be the same as single-channel.
2. We found single rank dimm need additional delay time for stutter.

[How]
Get information from each DIMM. Treat memory config as a single-channel
for asymmetric memory in bandwidth calculating.
Add additional delay time for single rank dimm.

19cc1f3829 drm/amd/display: fixed divide by zero kernel crash during dsc enablement
[why]
During dsc enable, a divide by zero condition triggered the
kernel crash.

[how]
An IGT test, which enable the DSC, was crashing at the time of
restore the default dsc status, becaue of h_totals value
becoming 0. So add a check before divide condition. If h_total
is zero, gracefully ignore and set the default value.

f83d2a214d drm/amd/display: wait vblank when stream enabled and update dpp clock
[Why]
When boot into OS, seamless boot device won't blank stream.
Driver update dpp clock when scanline position in vactive will show
garbage on screen.

[How]
Wait for vblank for seamless boot edp display when driver update dpp clock.
The apply seamless boot flag will be clear when OS call SetVisibility on.
Therefore we only wait for vblank once after boot into OS.

[Why]
Underflow observed when disabling PIP overlay in-game when
vsync is disabled, due to OTC master lock not working with
game pipe which is immediate flip.

[How]
When performing a full update, override flip_immediate value
