c707ea82c7 drm/amd/display: Ensure DMCUB idle before reset on DCN31/DCN35
[Why]
If we soft reset before halt finishes and there are outstanding
memory transactions then the memory interface may produce unexpected
results, such as out of order transactions when the firmware next runs.

These can manifest as random or unexpected load/store violations.

[How]
Increase the timeout before soft reset to ensure the DMCUB has quiesced.
This is effectively 1s maximum based on experimentation.

Use the enable bit check on DCN31 like we're doing on DCN35 and reorder
the reset writes to follow the HW programming guide.

Ensure we're reading SCRATCH7 instead of SCRATCH8 for the HALT code.
No current versions of DMCUB firmware use the SCRATCH8 boot bit to
dynamically switch where the HALT code goes to maintain backwards
compatibility with PSP.

This reverts commit 50f040c53e ("drm/amd/display: Increase halt
timeout for DMCUB to 1s")

There's two issues here:
1. Each poll is closer to 10us than 1us so it stalls for 15s on PNP.
2. We're reading the wrong scratch register to check for the HALT code.

0dfcc2bf26 drm/amd/display: Fix DMUB reset sequence for DCN401
[WHY]
It should no longer use DMCUB_SOFT_RESET as it can result
in the memory request path becoming desynchronized.

[HOW]
To ensure robustness in the reset sequence:
1) Extend timeout on the "halt" command sent via gpint, and check for
controller to enter "wait" as a stronger guarantee that there are no
requests to memory still in flight.
2) Remove usage of DMCUB_SOFT_RESET
3) Rely on PSP to reset the controller safely

b74f46f3ce drm/amd/display: Request HW cursor on DCN3.2 with SubVP
[why]
When SubVP is active the HW cursor size is limited to 64x64, and
anything larger will force composition which is bad for gaming on
DCN3.2 if the game uses a larger cursor.

[how]
If HW cursor is requested, typically by a fullscreen game, do not
enable SubVP so that up to 256x256 cursor sizes are available for
DCN3.2.

c3c584c18c drm/amd/display: fix type mismatch in CalculateDynamicMetadataParameters()
There is a type mismatch between what CalculateDynamicMetadataParameters()
takes and what is passed to it. Currently this function accepts several
args as signed long but it's called with unsigned integers and integer. On
some systems where long is 32 bits and one of these unsigned int params is
greater than INT_MAX it may cause passing input params as negative values.

Fix this by changing these argument types from long to unsigned int and to
int respectively. Also this will align the function's definition with
similar functions in other dcn* drivers.

8adeff83a3 drm/amd/display: stop DML2 from removing pipes based on planes
[Why]
Transitioning from low to high resolutions at high refresh rates caused grey corruption.
During the transition state, there is a period where plane size is based on low resultion
state and ODM slices are based on high resoultion state, causing the entire plane to be
contained in one ODM slice. DML2 would turn off the pipe for the ODM slice with no plane,
causing an underflow since the pixel rate for the higher resolution cannot be supported on
one pipe. This change stops DML2 from turning off pipes that are mapped to an ODM slice
with no plane. This is possible to do without negative consequences because pipes can now
take the minimum viewport and draw with zero recout size, removing the need to have the
pipe turned off.

[How]
In map_pipes_from_plane(), remove "check" that skips ODM slices that are not covered by
the plane. This prevents the pipes for those ODM slices from being freed.

7c6518c1c7 drm/amd/display: Update FIXED_VS Link Rate Toggle Workaround Usage
[WHY]
Previously the 128b/132b LTTPR support DPCD field was used to decide if
FIXED_VS training sequence required a rate toggle before initiating LT.

When running DP2.1 4.9.x.x compliance tests, emulated LTTPRs can report
no-128b/132b support which is then forwarded by the FIXED_VS retimer.
As a result this test exposes the rate toggle again, erroneously causing
failures as certain compliance sinks don't expect this behaviour.

[HOW]
Add new DPCD register defines/reads to read LTTPR IEEE OUI and device ID.

Decide whether to perform the rate toggle based on the LTTPR's IEEE OUI
which guarantees that we only perform the toggle on affected retimers.

ab021b9f31 drm/amd/display: ACPI Re-timer Programming
[Why]
We must implement an ACPI re-timer programming interface and notify
ACPI driver whenever a PHY transition is about to take place.

Because some trace lengths on certain platforms are very long,
then a re-timer may need to be programmed whenever a PHY transition
takes place. The implementation of this re-timer programming interface
will notify ACPI driver that PHY transition is taking place and it
will trigger the re-timer as needed.

First we need to gather retimer information from ACPI interface.

Then, in the PRE case, the re-timer interface needs to be called before we call
transmitter ENABLE.
In the POST case, it has to be called after we call transmitter DISABLE.

[How]
Implemented ACPI retimer programming interface.

73e686939c drm/amd/display: dpia should avoid encoder used by dp2
[WHY]
In current HPO DP2 implementation, driver would enable/disable DIG
encoder when configuring HPO DP2. Therefore, usb4 dp tunnelling should
not use the DIG encoder if the corresponded phy is used by a HPO DP2
stream.

[HOW]
A DP2 stream is treated as a dig stream.

72d7a7fa1f drm/amd/display: Guard against setting dispclk low when active
[Why]
We should never apply a minimum dispclk value while in prepare_bandwidth
or while displays are active. This is always an optimization for when
all displays are disabled.

[How]
Defer dispclk optimization until safe_to_lower = true and display_count
reaches 0.

Since 0 has a special value in this logic (ie. no dispclk required)
we also need adjust the logic that clamps it for the actual request
to PMFW.

51d1b33854 drm/amd/display: add workaround flag to link to force FFE preset
[Why]
There have been instances of some monitors being unable to link train on
their reported link speed using their selected FFE preset. If a different
FFE preset is found that has a higher rate of success during link training
this workaround can be used to force its FFE preset.

[How]
A new link workaround flag is made called force_dp_ffe_preset. The flag is
checked in override_training_settings and will set lt_settings->ffe_preset
which is null if the flag is not set. The flag is then set in
override_lane_settings.

e8bffa52e0 drm/amd/display: Don't try AUX transactions on disconnected link
[Why]
Setting link DPMS off in response to HPD disconnect creates AUX
transactions on a link that is supposed to be disconnected. This can
cause issues in some cases when the sink re-asserts HPD and expects
source to re-enable the link.

[How]
Avoid AUX transactions on disconnected link.

36681f15bb drm/amd/display: Account For OTO Prefetch Bandwidth When Calculating Urgent Bandwidth
[Why]
1) The current calculations for OTO prefetch bandwidth do not consider the number of DPP pipes in use.
As a result, OTO prefetch bandwidth may be larger than the vactive bandwidth if multiple DPP pipes are used.
OTO prefetch bandwidth should never exceed the vactive bandwidth.

2) Mode programming may be mismatched with mode support
In cases where mode support has chosen to use the equalized (equ) prefetch schedule,
mode programming may end up using oto prefetch schedule instead.
The bandwidth required to do the oto schedule may end up being higher than the equ schedule.
This can cause the required urgent bandwidth to exceed the available urgent bandwidth.

[How]
Output the oto prefetch bandwidth and incorperate it into the urgent bandwidth calculations
even if the prefetch schedule being used is not the oto schedule.

Cursor corruption will happen if we update the cursor surface
in this gap.

[How]
Modify the cursor request mode to the beginning prefetch always
and avoid wraparound calculation issues.

3a7810c212 drm/amd/display: Increase block_sequence array size
[Why]
It's possible to generate more than 50 steps in hwss_build_fast_sequence,
for example with a 6-pipe asic where all pipes are in one MPC chain. This
overflows the block_sequence buffer and corrupts block_sequence_steps,
causing a crash.

[How]
Expand block_sequence to 100 items. A naive upper bound on the possible
number of steps for a 6-pipe asic, ignoring the potential for steps to be
mutually exclusive, is 91 with current code, therefore 100 is sufficient.

41df56b1fc drm/amd/display: Use Nominal vBlank If Provided Instead Of Capping It
[Why/How]
vBlank used to determine the max vStartup is based on the smallest between
the vblank provided by the timing and vblank in ip_caps.
Extra vblank time is not considered if the vblank provided by the timing ends
up being higher than what's defined by the ip_caps

Use 1 less than the vblank size in case the timing is interlaced
so vstartup will always be less than vblank_nom.

820ccf8cb2 drm/amd/display: Respect user's CONFIG_FRAME_WARN more for dml files
Currently, there are several files in drm/amd/display that aim to have a
higher -Wframe-larger-than value to avoid instances of that warning with
a lower value from the user's configuration. However, with the way that
it is currently implemented, it does not respect the user's request via
CONFIG_FRAME_WARN for a higher stack frame limit, which can cause pain
when new instances of the warning appear and break the build due to
CONFIG_WERROR.

Adjust the logic to switch from a hard coded -Wframe-larger-than value
to only using the value as a minimum clamp and deferring to the
requested value from CONFIG_FRAME_WARN if it is higher.

Updating the cursor enablement register can be a slow operation and accumulates
when high polling rate cursors cause frequent updates asynchronously to the
cursor position.

[how]
Since the cursor enable bit is cached there is no need to update the
enablement register if there is no change to it.  This removes the
read-modify-write from the cursor position programming path in HUBP and
DPP, leaving only the register writes.

a8d42cd228 drm/amd/display: mark static functions noinline_for_stack
When compiling allmodconfig (CONFIG_WERROR=y) with clang-19, see the
following errors:

.../display/dc/dml2/display_mode_core.c:6268:13: warning: stack frame size (3128) exceeds limit (3072) in 'dml_prefetch_check' [-Wframe-larger-than]
.../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7236:13: warning: stack frame size (3256) exceeds limit (3072) in 'dml_core_mode_support' [-Wframe-larger-than]

Mark static functions called by dml_prefetch_check() and
dml_core_mode_support() noinline_for_stack to avoid them become huge
functions and thus exceed the frame size limit.

A way to reproduce:
$ git checkout next-20250107
$ mkdir build_dir
$ export PATH=/tmp/llvm-19.1.6-x86_64/bin:$PATH
$ make LLVM=1 O=build_dir allmodconfig
$ make LLVM=1 O=build_dir drivers/gpu/drm/ -j

The way how it chose static functions to mark:
[0] Unset CONFIG_WERROR in build_dir/.config.
To get display_mode_core.o without errors.

[1] Get a function list called by dml_prefetch_check().
$ sed -n '6268,6711p' drivers/gpu/drm/amd/display/dc/dml2/display_mode_core.c \
  | sed -n -r 's/.*\W(\w+)\(.*/\1/p' | sort -u >/tmp/syms

[2] Get the non-inline function list.
Objdump won't show the symbols if they are inline functions.

$ make LLVM=1 O=build_dir drivers/gpu/drm/ -j
$ objdump -d build_dir/.../display_mode_core.o | \
  ./scripts/checkstack.pl x86_64 0 | \
  grep -f /tmp/syms | cut -d' ' -f2- >/tmp/orig

[3] Get the full function list.
Append "-fno-inline" to `CFLAGS_.../display_mode_core.o` in
drivers/gpu/drm/amd/display/dc/dml2/Makefile.

$ make LLVM=1 O=build_dir drivers/gpu/drm/ -j
$ objdump -d build_dir/.../display_mode_core.o | \
  ./scripts/checkstack.pl x86_64 0 | \
  grep -f /tmp/syms | cut -d' ' -f2- >/tmp/noinline

[4] Get the inline function list.
If a symbol only in /tmp/noinline but not in /tmp/orig, it is a good
candidate to mark noinline.

$ diff /tmp/orig /tmp/noinline

Chosen functions and their stack sizes:
CalculateBandwidthAvailableForImmediateFlip [display_mode_core.o]:144
CalculateExtraLatency [display_mode_core.o]:176
CalculateTWait [display_mode_core.o]:64
CalculateVActiveBandwithSupport [display_mode_core.o]:112

4caacd1671 drm/amd/display: Do not elevate mem_type change to full update
[Why]

There should not be any need to revalidate bandwidth on memory placement
change, since the fb is expected to be pinned to DCN-accessable memory
before scanout. For APU it's DRAM, and DGPU, it's VRAM. However, async
flips + memory type change needs to be rejected.

[How]

Do not set lock_and_validation_needed on mem_type change. Instead,
reject an async_flip request if the crtc's buffer(s) changed mem_type.

This may fix stuttering/corruption experienced with PSR SU and PSR1
panels, if the compositor allocates fbs in both VRAM carveout and GTT
and flips between them.

aa6713fa20 drm/amd/display: Do not wait for PSR disable on vbl enable
[Why]

Outside of a modeset/link configuration change, we should not have to
wait for the panel to exit PSR. Depending on the panel and it's state,
it may take multiple frames for it to exit PSR. Therefore, waiting in
all scenarios may cause perceived stuttering, especially in combination
with faster vblank shutdown.

[How]

PSR1 disable is hooked up to the vblank enable event, and vice versa. In
case of vblank enable, do not wait for panel to exit PSR, but still wait
in all other cases.

We also avoid a call to unnecessarily change power_opts on disable -
this ends up sending another command to dmcub fw.

When testing against IGT, some crc tests like kms_plane_alpha_blend and
amd_hotplug were failing due to CRC timeouts. This was found to be
caused by the early return before HW has fully exited PSR1. Fix this by
first making sure we grab a vblank reference, then waiting for panel to
exit PSR1, before programming hw for CRC generation.

e4479aecf6 drm/amd/display: Increase sanitizer frame larger than limit when compile testing with clang
Commit 24909d9ec7 ("drm/amd/display: Overwriting dualDPP UBF values
before usage") added a new warning in dml2/display_mode_core.c when
building allmodconfig with clang:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6268:13: error: stack frame size (3128) exceeds limit (3072) in 'dml_prefetch_check' [-Werror,-Wframe-larger-than]
   6268 | static void dml_prefetch_check(struct display_mode_lib_st *mode_lib)
        |             ^

Commit be4e350931 ("drm/amd/display: DML21 Reintegration For Various
Fixes") introduced one in dml2_core/dml2_core_dcn4_calcs.c with the same
configuration:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7236:13: error: stack frame size (3256) exceeds limit (3072) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than]
   7236 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params)
        |             ^

In the case of the first warning, the stack usage was already at the
limit at the parent change, so the offending change was rather
innocuous. In the case of the second warning, there was a rather
dramatic increase in stack usage compared to the parent:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7032:13: error: stack frame size (2696) exceeds limit (2048) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than]
   7032 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params)
        |             ^

This is an unfortunate interaction between an issue with stack slot
reuse in LLVM that gets exacerbated by sanitization (which gets enabled
with all{mod,yes}config) and function calls using a much higher number
of parameters than is typical in the kernel, necessitating passing most
of these values on the stack.

While it is possible that there should be source code changes to address
these warnings, this code is difficult to modify for various reasons, as
has been noted in other changes that have occurred for similar reasons,
such as commit 6740ec97bc ("drm/amd/display: Increase frame warning
limit with KASAN or KCSAN in dml2").

Increase the frame larger than limit when compile testing with clang and
the sanitizers enabled to avoid this breakage in all{mod,yes}config, as
they are commonly used and valuable testing targets. While it is not the
best to hide this issue, it is not really relevant when compile testing,
as the sanitizers are commonly stressful on optimizations and they are
only truly useful at runtime, which COMPILE_TEST states will not occur
with the current build.

Updating the cursor enablement register can be a slow operation and accumulates
when high polling rate cursors cause frequent updates asynchronously to the
cursor position.

[how]
Since the cursor enable bit is cached there is no need to update the
enablement register if there is no change to it.  This removes the
read-modify-write from the cursor position programming path in HUBP and
DPP, leaving only the register writes.

080950cbdd drm/amd/display: Update dc_tiling_info union to structure
[WHY]
The `dc_tiling_info` union previously did not have a field to
specify the active GFX format, assuming only one format would
be used per DCN version. from DCN4+, support for switching
between different GFX formats is introduced, requiring a way
to track which format is currently in use.

[HOW]
Updated the `dc_tiling_info` union to include a new field that
explicitly indicates the currently used GFX format.
This allows the system to determine the active GFX format
and take the correct programming path accordingly.

[Description]
The union `dc_tiling_info` has been updated to support multiple
GFX formats by adding a new field for identifying the active format.
This update ensures that the correct programming path is followed
based on the selected format. All references to `dc_tiling_info`
in the codebase have been updated to reflect the new structure.

bce2dc0094 drm/amd/display: Add expanded HBlank field to dc_crtc_timing
[Why]
For DP HBlank expansion/reduction, the HBlank parameters of the original
EDID timing needs to be notified to the sink in order for the timing to
be reduced back to the original HBlank size.

[How]
Add parameter in dc_crtc_timing to track the increased HBlank.

3ed56d9e8f drm/amd/display: Add DP required HBlank size calc to link interface
[Why]
Some features, such as HBlank expansion/reduction, needs to know how
much HBlank is required to support basic audio.

[How]
Add interface to link to calculate required HBlank size for a given
link + timing combination to support basic audio (i.e. 2-channel 48KHz).

149bacfe9c drm/amd/display: power up all gating blocks when releasing hw DCN35
[WHY & HOW]
Driver disable will deallocate framebuffer to reset IPS state, this will cause IPS start with
INIT state to blindly power gate ONO region to break power sequence. All the gating blocks
should be powered up when releasing hw to ensure all the power optimizations are identical to pre-OS.

away the compiler warning fix from commit 2fde4fdddc
("drm/amd/display: Avoid -Wenum-float-conversion in
add_margin_and_round_to_dfs_grainularity()"), causing the warning to
reappear.

Apply the fix again to resolve the warning.

Re-apply again after commit be4e350931 ("drm/amd/display: DML21 Reintegration For Various Fixes")

ab75a0d2e0 drm/amd/display: fix divide error in DM plane scale calcs
dm_get_plane_scale doesn't take into account plane scaled size equal to
zero, leading to a kernel oops due to division by zero. Fix by setting
out-scale size as zero when the dst size is zero, similar to what is
done by drm_calc_scale(). This issue started with the introduction of
cursor ovelay mode that uses this function to assess cursor mode changes
via dm_crtc_get_cursor_mode() before checking plane state.

It fixes page fault faced by Cosmic users on AMD display versions that

commit 7fb363c575 ("drm/amd/display: Let drm_crtc_vblank_on/off manage interrupts")
lets drm_crtc_vblank_* to manage interrupts in amdgpu_dm_crtc_set_vblank,
and amdgpu_irq_get/put do not need to be called here.  Part of that
patch got lost somehow, so fix it up.

83626efdce drm/amd/display: Disable MPC rate control on ODM pipe update
[Why]
Seamless boot skips MPC init for the active pipe, resulting in stale MPC
rate control state being retained. This will cause issues since other
logic assumes it is disabled (as DCN30 and newer does not need it).

[How]
Disable MPC rate control on ODM pipe update to cover the seamless boot
case.

04d6273fae Revert "drm/amd/display: Fix green screen issue after suspend"
This reverts commit 87b7ebc2e1.

A long time ago, we had an issue with the Raven system when it was
connected to two displays: one with DP and another with HDMI. After the
system woke up from suspension, we saw a solid green screen caused by an
underflow generated by bad DCC metadata. To workaround this issue, the
'commit 87b7ebc2e1 ("drm/amd/display: Fix green screen issue after
suspend")' was introduced to disable the DCC for a few frames after in
the resume phase. However, in hindsight, this solution was probably a
workaround at the kernel level for some issues from another part
(probably other driver components or user space). After applying this
patch and trying to reproduce the green issue in a similar hardware
system but using the latest kernel and userspace, we cannot see the
issue, which makes this workaround obsolete and creates extra
unnecessary complexity to the code; for all of this reason, this commit
reverts the original change.

57a793a74f drm/amd/display: Apply (some) policy for DML2 formulation on DCN35/DCN351
[Why]
Dropping the entirety of dml2_policy_build_synthetic_soc_states exposes
an issue for states that cannot be filled via bbox_overrides and rely on
the default parameters that may or may not be present depending on the
DM.

For amdgpu_dm this results in missing parameters for most of the struct
in higher states:

- sr_exit_time_us
- sr_enter_plus_exit_time_us
- sr_exit_z8_time_us
- sr_enter_plus_exit_z8_time_us
- urgent_latency_pixel_data_only_us
- urgent_latency_pixel_mixed_with_vm_data_us
- urgent_latency_vm_data_only_us
- dram_clock_change_latency_us
- fclk_change_latency_us
- usr_retraining_latency_us
- writeback_latency_us
- urgent_latency_adjustment_fabric_clock_component_us
- urgent_latency_adjustment_fabric_clock_reference_mhz
- dscclk_mhz
- phyclk_mhz
- phyclk_d18_mhz
- phyclk_d32_mhz
- use_ideal_dram_bw_strobe

[How]
Copy from the first state, applying a minimal policy to set max clocks
for SOC independent values.

Then copy the SOC dependent ones from the states modified by
bbox_overrides.

550949c67c drm/amd/dp_mst: Expose a connector to kernel users after it's properly initialized
After a connector is added to the drm_mode_config::connector_list, it's
visible to any in-kernel users looking up connectors via the above list.
Make sure that the connector is properly initialized before such
look-ups, by initializing the connector with
drm_connector_dynamic_init() - which doesn't add the connector to the
list - and registering it with drm_connector_dynamic_register() - which
adds the connector to the list - after the initialization is complete.

v2: Fix s/drm_connector_dynamic_register()/drm_connector_dynamic_init()
    typo in the commit log.

24909d9ec7 drm/amd/display: Overwriting dualDPP UBF values before usage
[WHY]
Right now in dml2 mode validation we are calculating UBF parameters for
prefetch calculation for single and dual DPP scenarios. Data structure
to store such values are just 1D arrays, the single DPP values are
overwritten by the dualDPP values, and we end up using dualDPP for
prefetch calculations twice (once in place of singleDPP support check
and again for dual).

This naturally leads to many problems, one of which validating a mode in
"singleDPP" (when we used dual DPP parameters) and sending the singleDPP
parameters to mode programming, if we cannot support then we observe the
corruption as described in the ticket.

[HOW]
UBF values need to have 2d arrays to store values specific to single and
dual DPP states to avoid single DPP values being overwritten. Other
parameters are recorded on a per state basis such as prefetch UBF values
but they are in the same loop used for calculation and at that point its
fine to overwrite them, its not the case for plain UBF values.

5a498172c8 drm/amd/display: Make DMCUB tracebuffer debugfs chronological
[Why]

Previously, the debugfs did a simple dump of the tracebuffer region.
Because the tracebuffer is a ring, it meant that the entries printed may
not be in chronological order if the ring rolled over. This makes
parsing the tracelog cumbersome.

[How]

Since dmcub provides the current entry count, use that to determine
the latest tracelog entry and output the log chronologically.

Also, the fb region size is not accurate of the actual tracebuffer size;
it has been padded to alignment requirements. Use the tracebuffer size
reported by the fw meta_info, if available. If not, a fallback to the
hardcoded default is needed. To make this value available to other .c
files, its define was moved to dmub_srv.h.

Also, print a indicator at the start of the log if rollover occurred.

Some of the firmware that is loaded by amdgpu is not actually required.
For example the ISP firmware on some SoCs is optional, and if it's not
present the ISP IP block just won't be initialized.

The firmware loader core however will show a warning when this happens
like this:
```
Direct firmware load for amdgpu/isp_4_1_0.bin failed with error -2
```

To avoid confusion for non-required firmware, adjust the amd-ucode helper
to take an extra argument indicating if the firmware is required or
optional.

On optional firmware use firmware_request_nowarn() instead of
request_firmware() to avoid the warnings.

8488646966 drm/amd/display: Don't allow IPS2 in D0 for RCG Dynamic
[Why]
The existing changes to the DPMS off flag should help reduce
accidental entry, but this change further restricts the entry condition.

[How]
Record last power state as sent to DMUB.
Don't send IPS2 allow if it's D0.

70fec46519 drm/amd/display: Populate chroma prefetch parameters, DET buffer fix
[WHY]
Soft hang/lag observed during 10bit playback + moving cursor, corruption
observed in other tickets for same reason, also failing MPO.

1. Currently, we are always running
   calculate_lowest_supported_state_for_temp_read which is only
   necessary on dGPU
2. Fast validate path does not apply DET buffer allocation policy
3. Prefetch UrgBFactor chroma parameter not populated in prefetch
   calculation

[HOW]
1. Add a check to see if we are on APU, if so, skip the code
2. Add det buffer alloc policy checks to fast validate path
3. Populate UrgentBurstChroma param in call to calculate
   UrgBChroma prefetch values

-revision commits: small formatting/brackets/null check addition + remove test change + dGPU code

7f81a80a68 drm/amd/display: Add disable_ips_in_dpms_off flag for IPS
[WHY]
It's possible we still allow IPS2 when all streams are DPMS off but this
is unexpected.

[HOW]
Pass the DM config value into DC so it can use the pure stream count
to decide. We will be in 0 streams for S0i3 so this will still allow
it for D3.

[WHY]
EASF only applies to luma. Previously both luma and chroma taps
were checked to determine whether to enable EASF.

to enable EASF or not.
