Hamza Mahfooz 65550a9cc5 drm/amd/display: disable FPO and SubVP for older DMUB versions on DCN32x
There have recently been changes that break backwards compatibility,
that were introduced into DMUB firmware (for DCN32x) concerning FPO and
SubVP. So, since those are just power optimization features, we can just
disable them unless the user is using a new enough version of DMUB
firmware.

Aric Cyr 6e4337f695 drm/amd/display: Unify optimize_required flags and VRR adjustments
[why]
There is only a single call to dc_post_update_surfaces_to_stream so
there is no need to have two flags to control it. Unifying this to a
single flag allows dc_stream_adjust_vmin_vmax to skip actual
programming when there is no change required.

[how]
Remove wm_optimze_required flag and set only optimize_required in its
place. Then in dc_stream_adjust_vmin_vmax, check that the stream timing
range matches the requested one and skip programming if they are equal.

Alvin Lee 9a902a9073 drm/amd/display: Force p-state disallow if leaving no plane config
[Description]
- When we're in a no plane config, DCN is always asserting
  P-State allow
- This creates a scenario where the P-State blackout can start
  just as VUPDATE takes place and transitions the DCN config to
  a one where one or more HUBP's are active which can result in
  underflow
- To fix this issue, force p-state disallow and unforce after
  the transition from no planes case -> one or more planes active

Alvin Lee dd4e4bb288 drm/amd/display: For prefetch mode > 0, extend prefetch if possible
[Description]
For mode programming we want to extend the prefetch as much as possible
(up to oto, or as long as we can for equ) if we're not already applying
the 60us prefetch requirement. This is to avoid intermittent underflow
issues during prefetch.

The prefetch extension is applied under the following scenarios:
1. We're in prefetch mode 1 (i.e. we don't support MCLK switch in blank)
2. We're using subvp or drr methods of p-state switch, in which case we
   we don't care if prefetch takes up more of the blanking time

Mode programming typically chooses the smallest prefetch time possible
(i.e. highest bandwidth during prefetch) presumably to create margin between
p-states / c-states that happen in vblank and prefetch. Therefore we only
apply this prefetch extension when p-state in vblank is not required (UCLK
p-states take up the most vblank time).

This behavior was introduced by commit d9e865826c ("drm/amd/display:

read back was less than 1 nit.

Restore this code so that the backlight brightness is restored to the

recommended by hardware team as refclk is a fixed value which could
cause unnecessary power consumption or it could be not enough for large

dynamically generated DSCCLK by DTO. So DSCCLK is programmable based on
current pixel clock and dispclk.

Charlene Liu c59397eff9 drm/amd/display: revert removing otg toggle w/a back when no active display

- dual display, compliance, toggling between the displays
- switching between 120Hz 420 -> 144Hz 444 and vice versa
- switching between 144Hz -> 60Hz TMDS or vice versa

It'd typically involve TMDS in some capacity since that's the only link
signal we leave the OTG running but DIO/PHY off you can hit this in
cases where you have multiple displays as well it syncs with the first
active OTG, so if you had OTG[0] mapped and FIFO off you'd hit it even
if OTG[1] was mapped and had FIFO

Krunoslav Kovac d5df648ec8 drm/amd/display: Change dither policy for 10bpc to round
We use spatial dither by default for all output bpc (6/8/10). While it
makes some sense for FP16, for ARGB2101010 surfaces it makes little
sense as even if we skip color pipeline to preserve bit accuracy,
spatial dither adds random noise so a few percent pixels are 1 bit off.
This commit chages the 10bpc out dither policy to rounding.

Also, in Polaris/Vega times, policy used to be round for 10bpc out; it
looks like it got inadvertently changed for Navi. Difference is only
detectable with capture cards.

[Why]
DTBCLK is enabled on idle and it will burn power.

[How]
There's a few issues here:
- Always enabling DTBCLK on clock manager init
- Setting refclk when DTBCLK is supposed to be disabled
- Not applying the correct calculated version refclk, but instead the
  base value which might be zero

On dtbclk_en change we'll message PMFW to enable or disable the clock
accordingly.

The DTBDTO will be then based on refclk, but it will be set to the
default fixed value if there was nothing calculated in DML despite the
clock being considered enabled.

Nicholas Kazlauskas 5fcf74e002 drm/amd/display: Update DCN35 clock table policy
[Why]
The new table doesn't have an implicit mapping between Fclk SOC voltage
and MemClk and it currently builds the table off of number of Fclk
states rather than DcfClock states.

The DML table in use is not correct for functionality or power and
does not align with our existing policies for DCN3x.

[How]
Build the table based on DcfClock with the following assumptions:

1. Raising Soc voltage is the most expensive operation, so assume that
running at max DispClock or DppClock is preferable.

2. Assume that we can run at max Fclk / MemClk at any state, but
restrict the maximum state to the very last entry in the table as the
worst case scenario.

3. Assume that Fclk always has a 2x multiplier on DcfClock unless the
table specifies something lower.

Nicholas Kazlauskas fcd94ef1b3 drm/amd/display: Remove min_dst_y_next_start check for Z8
[Why]
Flickering occurs on DRR supported panels when engaged in DRR due to
min_dst_y_next becoming larger than the frame size itself.

[How]
In general, we should be able to enter Z8 when this is engaged but it
might be a net power loss even if the calculation wasn't bugged.

Don't support enabling Z8 during the DRR region.

- Also ensure to block drr + vblank cases to prevent unexpected
  enablement of new display configs
- Update SW cursor fallback for these new potential cases as well

Wayne Lin 83a79dd6f4 drm/amd/display: adjust flow for deallocation mst payload
[Why]
MST relevant variables are maintained at drm side. As the result, we
still have to call drm_dp_remove_payload_part2() to update the relevant
values regardless the link is under mst mode or not. We used to have a
workaround patch to tackle this: commit 3d8fcc6740 ("drm/amd/display:
Extract temp drm mst deallocation wa into its own function")

Now it's time to remove the workaround and adjust the flow.

[How]
During deallocate_mst_payload(), source actually doesn't send out
ALLOCATE_PAYLOAD at the end as like the flow in allocate_mst_payload().
Call function dm_helpers_dp_mst_send_payload_allocation() at the end of
deallocate_mst_payload() is a bit confusing.

Separate dm_helpers_dp_mst_send_payload_allocation() into 2 functions.
Have a new function dm_helpers_dp_mst_update_mst_mgr_for_deallocation()
to replace dm_helpers_dp_mst_send_payload_allocation() for payload
deallocation.

Camille Cho 43b8ac4b34 drm/amd/display: Simplify brightness initialization
[Why]
Remove the brightness cache in DC. It uses a single value to represent
the brightness for both SDR and HDR mode. This leads to flash in HDR
on/off. It also unconditionally programs brightness as in HDR mode. This
may introduce garbage on SDR mode in miniLED panel.

[How]
Simplify the initialization flow by removing the DC cache and taking
what panel has as default. Expand the mechanism for PWM to DPCD Aux to
restore cached brightness value generally.

increment dml pipe index when current dc pipe is not free.

that are duplicates of one another. To properly
handle this scenario, pipe index to plane index
mapping is used to decide which plane is being
processed and programmed.

[how]
Create static array of pipe index to plane index map.
Populate the array properly and use in appropriate places.

Nathan Chancellor 6740ec97bc drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml2
When building ARCH=x86_64 allmodconfig with clang, which will typically
have sanitizers enabled, there is a warning about a large stack frame.

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6265:13: error: stack frame size (2520) exceeds limit (2048) in 'dml_prefetch_check' [-Werror,-Wframe-larger-than]
   6265 | static void dml_prefetch_check(struct display_mode_lib_st *mode_lib)
        |             ^
  1 error generated.

Notably, GCC 13.2.0 does not do too much of a better job, as it is right
at the current limit of 2048 (and others have reported being over with
older GCC versions):

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c: In function 'dml_prefetch_check':
  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6705:1: error: the frame size of 2048 bytes is larger than 1800 bytes [-Werror=frame-larger-than=]
   6705 | }
        | ^

In the past, these warnings have been avoided by reducing the number of
parameters to various functions so that not as many arguments need to be
passed on the stack. However, these patches take a good amount of effort
to write despite being mechanical due to code structure and complexity
and they are never carried forward to new generations of the code so
that effort has to be expended every new hardware generation, which
becomes harder to justify as time goes on.

To avoid having a noticeable or lengthy breakage in all{mod,yes}config,
which are easy testing targets that have -Werror enabled, increase the
limit for configurations that have KASAN or KCSAN enabled by 50% so that
cases of extremely poor code generation can still be caught while not
breaking the majority of builds. CONFIG_KMSAN also causes high stack
usage but the frame limit is already set to zero when it is enabled,
which is accounted for by the check for CONFIG_FRAME_WARN=0 in the dml2
Makefile.

This commit mitigates part of this problem by extracting the prefetch
code to its own function. After applying this commit, the stack size
reduces from 2736 to 2464, however, the stack size issue becomes part of
the new function.

George Shen 9af4377fd5 drm/amd/display: Disable SubVP if test pattern is enabled
[Why]
Enabling DPG causes HUBP to stay in blank constantly. If DPG is enabled
while an MCLK switch is taking place with SubVP, it will cause the MCLK
to never complete. This is because SubVP MCLK switch relies a HUBP
VLine interrupt, which will never occur when HUBP is constantly in
blank.

[How]
Disable SubVP when test pattern is enabled.

George Shen 051d90070d drm/amd/display: Refactor DPG test pattern logic for ODM cases
[Why]
Current DPG test pattern logic does not account for ODM configuration
changes after test pattern has already been programmed. For example, if
ODM2:1 is enabled after test pattern is already being output, the second
pipe is not programmed to output test pattern, causing half the screen
to be black.

[How]
Move DPG test pattern parameter calculations into separate function.
Whenever ODM pipe configuration changes, re-calculate DPG test pattern
parameters and program DPG if test pattern is currently enabled.

Sebastian Andrzej Siewior 2091ac6903 drm/amd/display: Move the memory allocation out of dcn20_validate_bandwidth_fp().
dcn20_validate_bandwidth_fp() is invoked while FPU access has been
enabled. FPU access requires disabling preemption even on PREEMPT_RT.
It is not possible to allocate memory with disabled preemption even with
GFP_ATOMIC on PREEMPT_RT.

Move the memory allocation before FPU access is enabled.
To preserve previous "clean" state of "pipes" add a memset() before the
second invocation of dcn20_validate_bandwidth_internal() where the
variable is used.

But with MPC pipes, downstream pipes have null stream_enc and will
 cause crash.

[How]
Only call stream_enc functions for pipes that are OTG master.

To enable pre-blending and post-blending gamut_remap matrix supports at

DPP for DCN families that support both.

It was tested using IGT KMS color tests for DRM CRTC CTM property and it
