02fd27e6cf drm/amd/display: no 3D and blnd LUT as DPP color caps for DCN401
Match what is declared as DPP color caps with hw caps. DCN401 has MPC
shaper + 3D LUTs that are movable before and after blending (get from
plane or stream), but no DPP blend LUTs.

4465dd0e41 drm/amd/display: Refactor SubVP cursor limiting logic
[WHY]
There are several gaps that can result in SubVP being enabled with
incompatible HW cursor sizes, and unjust restrictions to cursor size due
to wrong predictions on future usage of SubVP.

[HOW]
- remove "prediction" logic in favor of tagging based on previous SubVP
  usage
- block SubVP if current HW cursor settings are incompatible
- provide interface for DM to determine if HW cursor should be disabled
  due to an attempt to enable SubVP

[Description]
This commit ensures that the correct GFX tiling information is passed
to DML. Depending on the active GFX format, the appropriate tiling info
is passed to DML. This change accommodates the different GFX formats
supported by latest platforms, ensuring compatibility and proper

bdf6068102 drm/amd/display: Implement bounds check for stream encoder creation in DCN401
'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.

The error message 'stream_enc_regs' 4 <= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior

Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.

Thus fixing Buffer overflow error in dcn401_stream_encoder_create

Found by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn401/dcn401_resource.c:1209 dcn401_stream_encoder_create() error: buffer overflow 'stream_enc_regs' 4 <= 5

5f30ee4930 drm/amd/display: quality improvements for EASF and ISHARP
[Why]
Update coefficients and LUT tables for scaler and sharpener
 to improve quality and support different use cases (SDR/HDR)

[How]
Move scaler coefficients to new file dc_spl_scl_easf_filters.c
Remove older coefficients file dc_sp_scl_filters_old.c
Update default taps for EASF support
Update LLS policy for DON'T CARE case
Update cositing offset from 0.5 to 0.25
Add support to adjust sharpness based on level, use case,
 and scaling ratio ( using discrete levels )
Apply sharpness to all RGB surfaces and both NV12 and P010
 video ( in fullscreen only ).  Upscale and 1:1 ratios only
Enable scaler when sharpening 1:1 ratios
Add support for coefficients that are in S1.10 format
 (convert to S1.12 format)

95134e5852 drm/amd/display: Add ASIC cap to limit DCC surface width
[Why]
Certain configurations of DCN401 require ODM4:1 to support DCC for 10K
surfaces. DCC should be conservatively disabled in those cases.

The issue is that current logic limits 10K surface DCC for all
configurations of DCN401.

[How]
Add DC ASIC cap to indicate max surface width that can support DCC.
Disable DCC if this ASIC cap is non-zero and surface width exceeds it.

52971387a0 drm/amd/display: DCN401 full power down in HW init if any link enabled
[Why]
During HW init, certain operations the driver performs are invalid on
enabled hardware in an unknown state (for example, setting all clock
values to minimum when the GPU is actively driving a display). There is
already code present to call HWSS->power_down during init when any link
is enabled in HW, but that function pointer is unpopulated for most asics.
We want to enable this codepath for DCN401, as it resolves the issue with
being unable to drive certain display configs on adapter re-enable, and we
can restore boot optimizations.

[How]
 - add power_down HWSS function for DCN401
 - remove debug bit to disable boot optimizations for DCN401

while the root cause is being investigated we can make sure everything is
being reset as a workaround, by disabling boot optimization.

while investigating, we can work around the issue by skipping toggling
