drm/amd/display: Update FIXED_VS Retimer HWSS Test Pattern Sequences

[WHY]
Need to fix some broken logic and sequencing in initial commit

[HOW]
Fix logic handling override deprogramming when exiting SQ128.

Don't exit early from dp_set_hw_lane_settings for DP2/FIXED_VS case.

Move LTTPR 128b/132b check out of requires_hwss and check during
runtime, as LTTPR caps are not populated on initial call.

Add pending_test_pattern to link state to allow HWSS to set FFE overrides
on retimer TX and/or skip setting APU TX FFE depending on requested pattern.

Use updated clock source for SQ128 override sequence.

Skip HW FFE preset programming when performing test pattern overrides.

drm/amd/display: treat plane clip size change as MED update type

[why]
When clip size is changed recout and viewport size would require an
update. When the update is clip size only current driver fails to
program the update into hardware.

type and reprogram scaling params in next program pipe.

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 3d8fcc6740c9 ("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.

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.

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.

drm/amd/display: Add z-state support policy for dcn35

[Why]
DML2 means that the dcn3x policy for calculating z-state support
no longer runs from validate_bandwidth.

This means we are unconditionally allowing Z8, the hardware default.

[How]
Port the policy over to DCN35, but with a few modifications:
- Don't use min_dst_y_next_start as a check for Z8/Z10 allow
- Add support for overriding the Z10 stutter period per ASIC
- Cleanup the code to make the policy assignment more clear

drm/amd/display: Improve x86 and dmub ips handshake

[Why]
There is a race condition between x86 and dmcub fw when attempting to exit
IPS2. Scenarios including exiting IPS2 before IPS2 has been entered. This
can cause unexpected hang when DMCUB attempt to exit while PMFW still
tries to enter IPS2.

[How]
A new design has been introduced to remove race conditions and improve the
handshake between x86 and DMCUB. An AON scratch register is borrowed from
PMFW to determine whether DMCUB has committed to IPS entry or not.

In the case when dmcub has committed IPS entry, x86 must poll until an exit
event occurred either from DMCUB(IPS1) or PMFW(IPS2). x86 will wait
upperbound of evaluation and IPS entry time to ensure IPS2 exit event has
been sent to PMFW.

drm/amd/display: Add structs for Freesync Panel Replay

In some instances, the GPU is transmitting repeated frame to the sink
without any updates or changes in the content. These repeat transmission
are wasteful, resulting in power draw in different aspects of the system

1. DCN is fetching the frame of data from DF/UMC/DRAM. This memory traffic
prevents power down of parts of this HW path.

2. GPU is transmitting pixel data to the display through the main link of
the DisplayPort interface. This prevents power down of both the Source
transmitter (TX) and the Sink receiver (RX)

The concepts of utilizing replay is similar to PSR, but there is a benefit of:
Source and Sink remaining synchronized which allows for
- lower latency when switching from replay to live frames
- enable the possibility of more use cases
- easy control of the sink's refresh rate during replay

Due to Source and Sink remaining timing synchronized, Replay can be activated
in more UI scenarios.

drm/amd/display: update extended blank for dcn314 onwards

[Why]
Flickering and underflow was observed when testing extended
blank on dcn314.

[What]
Vstartup is contrainted by vblank_nom, so adjusting it to include
non-adjusted vtotal in its calculation during freesync video
means that Vstartup is not changed when vtotal changes.
This fixed the flickering + underflow.

dc_extended_blank_supported function was removed
because extended blank is only relevant to when
zstate is supported. The increased vtotal during
freesync can be passed to dml regardless of whether
extended blank is supported or not, so this function is
not needed.

Updates were made recently in dml to the calculation of
min_dst_y_next_start. Dml input for dcn314 will now
always use the newer calculation for min_dst_y_next_start.
Dml input for older dcn versions remains untouched.

The variable optimized_min_dst_y_next_start
is replaced everywhere with min_dst_y_next_start,
and the updated dml allows min_dst_y_next_start to
increase to an optimized value during freesync video,
then return to default when freesync is disengaged.

Also removed registry key for controlling
extended blank feature.

drm/amd/display: fix is_timing_changed() prototype

drm/amd/display: Apply correct panel mode when reinitializing hardware

[Why]
When link training during engine recovery, ASSR might fail causing panel
mode to be reset to default. This should not happen for eDP as it
will prevent the panel from turning back on.

[How]
Added dp_panel_mode to struct dc_link to remember previously applied
panel mode. Do not reset panel mode to default while performing link
training if previously used panel mode = eDP.

Since this standard is very new and there are no existing 6.75 GBps

on enabling this feature until we can validate it with real hardware.

[How]
- Add boolean flag support_eDP1_5 in struct dc_debug_options.
- Enable the 6.75 link rate in reduce_link_rate(...) only when

drm/amd/display: convert link.h functions to function pointer style

[Why & How]
All dc subcomponents should call another dc component via function pointers
stored in a component structure. This is part of dc coding convention since
the beginning. The reason behind this is to improve encapsulation and
polymorphism. The function contract is extracted into a single link service
structure defined in link.h header file and implemented only in link_factory.c instead
of spreading across multiple files in link component file structure.

default. All instances of a dc_plane_cap maintain the default values of

there would be the same effect if it was deleted (assuming that those

drm/amd/display: 3.2.226

In this new version there are two major changes:

1) Transitioning to the new DC commit sequence

There is an extended effort to migrate to the new DC commit sequence
that better adheres to the DCN hardware constraints. Most of the code
was upstreamed already but not connected to amdgpu_dm, and in this new
DC version, our DM finally started to use it for all ASICs. This should
improve stability and enable us to improve how pipe split works.

2) Drop old CONFIG_DRM_AMD_DC_DCN in favor of new CONFIG_DRM_AMD_DC_FP

For historical reasons, we created CONFIG_DRM_AMD_DC_DCN to isolate
FPU-related code to only be used for DCN. Over the years, we lost
control over this guard, and it was spread in multiple areas. In this
new DC version, there is an effort to remove all unnecessary
CONFIG_DRM_AMD_DC_DCN and replace the others for CONFIG_DRM_AMD_DC_FP,
which better describes which type of code this guard is intended for.

Finally, this version brings along the following:
- Enable HostVM based on rIOMMU active
- Keep PHY active for dp confi
- Improves Z8
- Update clock table
- Code and directives clean up

There are two functions responsible for handling the DC commit state:
dc_commit_state and dc_commit_streams. Both have the same goal, but
dc_commit_streams surpess dc_commit_state in terms of completeness. For
this reason, maintaining these two functions makes maintainability
unnecessarily complicated. This commit replaces the old dc_commit_state
in favor of dc_commit_streams, and removes the old dc_commit_state.

drm/amd/display: disable SubVP + DRR to prevent underflow

[Why&How]
Temporarily disable SubVP+DRR since Xorg has an architectural limitation
where freesync will not work in a multi monitor configuration. SubVP+DRR
requires that freesync be working.

Whether OS has variable refresh setting enabled or not, the state on
the crtc remains same unless an application requests VRR. Due to this,
there is no way to know whether freesync will actually work or not
while we are on the desktop from the kernel's perspective.

If userspace does not have a limitation with multi-display freesync (for
example wayland), then this feature can be enabled by adding a
dcfeaturemask option to amdgpu on the kernel cmdline like:

amdgpu.dcfeaturemask=0x200

drm/amd/display: move public dc link function implementation to dc_link_exports

[why]
Link is a subcomponent in dc. DM should be aware of dc link structure
as one of the abstracted objects maintained by dc. However it should
have no idea of the existence of a link component in dc dedicated to
maintain the states of dc link structure. As such we are moving link interfaces
out of dc_link.h and directly added to dc.h. We are grandually fading out
the explicit inclusion of dc_link header and eventually delete it.

On dc side, since link is a subcomponent behind dc interfaces, it is not
a good idea to implement dc interfaces in each individual subcomponent
of link which is already a subcomponent of dc. So we are decoupling it
by implementing a dc_link_exports in dc. This file will be a thin
translation layer that breaks the dependency so link is able to make
interface changes without breaking DM.

drm/amd/display: Add debug option to skip PSR CRTC disable

[Why]
It's currently tied to Z10 support, and is required for Z10, but
we can still support Z10 display off without PSR.

We currently need to skip the PSR CRTC disable to prevent stuttering
and underflow from occuring during PSR-SU.

[How]
Add a debug option to allow specifying this separately.

drm/amd/display: Add Z8 allow states to z-state support list

[Why]
Even if we block Z9 based on crossover threshold it's possible to
allow for Z8.

[How]
There's support for this on DCN314, so update the support types to
include a z8 only and z8_z10 only state.

Update the decide_zstate_support function to allow for specifying
these modes based on the Z8 threshold.

DCN31 has z-state disabled, but still update the legacy code to
map z8_only = disallow and z10_z8_only = z10_only to keep the support
the same.

- Also add margin for the max VTOTAL possible for SubVP + DRR cases.
- Due to rounding errors in FW (integer arithmetic), the microschedule
calculation can get pushed to the next frame (incorrectly) in cases
where we use the max VTOTAL possible to complete the MCLK switch.
- When the rounding error occurs, we are only off by 1-2 lines,
use 40us margin which is working consistently.

drm/amd/display: Add function for validate and update new stream

DC stream can be seen as a representation of the DCN backend or the data
struct that represents the center of the display pipeline. The front end
(i.e., planes) is connected to the DC stream, and in its turn, streams
are connected to the DC link. Due to this dynamic, DC must handle the
following scenarios:

1. A stream is removed;
2. A new stream is created;
3. An unchanged stream had some updates on its planes.

These combinations require that the new stream data struct become
updated and has a valid global state. For handling multiple corner cases
associated with stream operations, this commit introduces a function
dedicated to manipulating stream changes and invokes the state
validation function after that.

drm/amd/display: Display does not light up after S4 resume

[Why]
Dpia hpd interrupt processing is disabled when entering S4/S0i3 and
would be reenabled after detection completes during resuming. Because,
keeping hpd interrupts enabled during detection leads to multiple
detections for the same hpd transition. There is a S4 case where dpia
hpd interrupt is missed when driver is in transitioning from hpd
interrupt processing disable to enable and the display does not light
up.

[How]
- Added dmub inbox command DMUB_CMD__DPIA_HPD_INT_ENABLE to explicitly
control dmub to issue dpia hpd interrupt or not. If dpia hpd interrupt
is disabled, dmub will keep the hpd pending and post it once driver
reenables dpia hpd interrupt or when querying with
DMUB_CMD__QUERY_HPD_STATE.
- Added dmub boot option dpia_hpd_int_enable_supported to notify dmub
about whether DMUB_CMD__DPIA_HPD_INT_ENABLE command would be used.

drm/amd/display: Fix various dynamic ODM transitions on DCN32

[Why&How]

Several transitions were fixed that will allow Dynamic ODM and MPO
transitions to be supported on DCN32.

1) Due to resource limitations, in certain scenarios that require an MPO
plane to be split, the features cannot be combined with the current
policy. This is due to unsafe transitions being required (OPP instance
per MPCC being switched on active pipe is not supported by DCN), to
support the split plane with ODM active as it moves across the viewport.
Dynamic ODM will now be disabled when MPO is required.

2) When exiting MPO and re-entering ODM, DC assigns an inactive pipe for
the next ODM pipe, which under previous power gating policy would result
in programming a gated DSC HW block. New policy dynamically
gates/un-gates DSC blocks when Dynamic ODM is active to support

transitions on DCN32 only.

3) Entry and exit from 3 plane MPO and Dynamic ODM requires a minimal
transition so that all pipes which require their MPCC OPP instance to
be changed have a full frame to be disabled before reprogramming. To
solve this, the Dynamic ODM policy now utilizes minimal state
transitions when entering or exiting 3 plane scenarios.

4) Various fixes to DCN32 pipe merge/split algorithm to support Dynamic
ODM and MPO transitions.

In summary, this commit fixes various transitions to support ODM->MPO
and MPO->ODM.

drm/amd/display: include soc._clock_tmp[] into DC's scratch region

Currently, we are using soc._clock_tmp[] to temporarily store and modify
data from soc.clock_limits[] before copying it back into
soc.clock_limits[] (because modifying data directly in
soc.clock_limits[] causes unintended behavior). However, this approach
has a number of downsides, such as:

1. struct _vcs_dpi_soc_bounding_box_st's creation/destruction
aren't well defined (which could mean more unintended
behavior).
2. Throwing "temp" varibles in structs everywhere doesn't make
for a particularly readable codebase.

For these reasons, we should get rid of soc._clock_tmp[] by defining a
struct scratch within struct dc that, contains within it all of the
temporary variables (including _clock_tmp[]) such that it is obvious how
they are intended to be used.

drm/amd/display: Add DCN reg offsets to DC

[Why&How]
Add a field to store the DCN IP offset for use with runtime offset
calculation

This offset is indexed using reg*_BASE_IDX for the corresponding
group of registers. For example, address of DIG_BE_CNTL instance 0 is
calculated like: dcn_reg_offsets[regDIG0_DIG_BE_CNTL_BASE_IDX] +
regDIG0_DIG_BE_CNTL.

{dcn,nbio}_reg_offsets are used only for the ASICs for which runtime
initializaion of offsets are enabled through the modified SR* macros
that contain an additional REG_STRUCT element in the macro definition.

DCN3.5+ will fail dc_create() if {dcn,nbio}_reg_offsets are null. They
are applicable starting with DCN32/321 and are not used for ASICs
upstreamed before them. ASICs before DCN32/321 will not contain any
computation that involves {dcn,nbio}_reg_offsets. For them, the
address/offset computation is done during compile time.

This is evident from the BASE_INNER definition for compile time vs run
time initialization:

Compile time init: #define BASE_INNER(seg) DCN_BASE__INST0_SEG ## seg
Run time init: #define BASE_INNER(seg) ctx->dcn_reg_offsets[seg]

BASE_INNER macro is local to each dcnxx_resource.c and hence different
ASICs can have either runtime or compile time initialization of offsets.

The computation of offset is done for registers all at once during
driver load and hence it does not introduce any performance overhead
during normal operation.

drm/amd/display: Exit SubVP if MPO in use

[Description]
Exit SubVP if MPO is in use since SubVP + MPO together is not supported.
- Don't add SubVP at validation time if we see MPO is in use

Issues fixed in the SubVP / MPO transition:
1. Enable phantom pipes in post unlock function to prevent underflow
when an active pipe is being transitioned to be a phantom pipe (VTG
updates take place right away). Also must wait for VUPDATE of the main
pipe to complete first

2. Don't wait for MPCC idle when transitioning a phantom pipe to an
actual pipe. MPCC_STATUS is never asserted due to OTG being off for
phantom pipes

3. When transitioning an active pipe to phantom, program DET right away
(same as disabling the pipe) or the DET update will only take when
the phantom pipe is enabled which can cause DET allocation errors.

4. For K1/K2 programming of phantom pipes, use same settings as the
main pipe. Also don't program K1 / K2 = 0xF ever since the field is only
1 / 2 bits wide.

drm/amd/display: Apply ODM 2:1 policy for single display configuration

[Why]
Most of the time, a single display uses the ODM combine. When using
multi-display, we use ODM combine only if it is necessary. These cases
are not flexible enough for us, and we can improve them to take
advantage of our hardware. We want to have more control over the ODM
policy.

[How]
This commit add a new debug flag named
enable_single_display_2to1_odm_policy to control the ODM policy and
another flag named enable_dp_dig_pixel_rate_div_policy to fine control
the ODM combine. This is possible by adding a new "pipe.dest" parameter
that can be set to ODM 2:1 combined if we use a single display. For
dynamic ODM combine, when using DP-DIG, DCN applies K2=2 settings for
ODM combine. Note that this feature affects the following registers:

- timing.pix_clk_100khz -> DP_VID_M, DP_VID_N
- requested_pix_clk_100hz -> DP_DTOn_PHASE
- OTGn_PIXEL_RATE_DIVK2
- DP_PIXEL_PER_CYCLE_PROCESSING_MODE
- DIG_FIFO_OUTPUT_PIXEL_MODE
- DP_VID_N_MUL

- Send calculated watermark to DMCUB for SubVP
- Adjust CAB mode message to PMFW
- Add a proper locking sequence for SubVP
- Various fixes to SubVP static analysis and determining SubVP config
- Currently SubVP not supported with pipe split so merge all pipes

drm/amd/display: Fix eDP not light up on resume

[why]
Only on VG, if external display is disconnected during S3 suspend, the
internal panel doesn't light up on resume because we set the power state
using an unsupported DPCD register SET_POWER. To check the register is
supported, we need to check SET_POWER_CAPABLE first which is
eDP-specific DPCD register field.

[how]
Check the SET_POWER_CAPABLE register field and decide the control of the
eDP power state based on the read register value.

drm/amd/display: Blank for uclk OC in dm instead of dc

[Why]
All displays need to be blanked during the uclk OC interface so that we can
guarantee pstate switching support. If the display config doesn't support
pstate switching, only using core_link_disable_stream will not enable it
as the front-end is untouched. We need to go through the full plane removal
sequence to properly program the pipe to allow pstate switching.

drm/amd/display: Blank eDP on enable drv if odm enabled

[Why]
For panels with pixel clock > 1200MHz that require ODM
in pre-OS, when driver is disabled in OS, odm is enabled.
Upon driver enablement, corruption is seen if
odm was originally enabled. DP_PIXEL_COMBINE and
pixelclk must be programmed prior to programming the
optc-odm registers. However, eDP displays aren't blanked
prior to initializing odm in this case.

[How]
Upon driver enablement, check whether odm is enabled,
if so, blank eDP prior to programming optc-odm
registers.

drm/amd/display: add Coverage blend mode for overlay plane

According to the KMS man page, there is a
"Coverage" alpha blend mode that assumes the
pixel color values have NOT been pre-multiplied
and will be done when the actual blending to
the background color values happens.

Previously, this mode hasn't been enabled
in our driver and it was assumed that all
normal overlay planes are pre-multiplied
by default.

When a 3rd party app is used to input a image
in a specific format, e.g. PNG, as a source
of a overlay plane to blend with the background
primary plane, the pixel color values are not
pre-multiplied. So by adding "Coverage" blend
mode, our driver will support those cases.

Issue fixed: Overlay plane alpha channel blending is incorrect
Issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/1769

Reference:
https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-composition-properties

Adding Coverage support also enables IGT
kms_plane_alpha_blend Coverage subtests:
1. coverage-7efc
2. coverage-vs-premult-vs-constant

Changes
1. Add DRM_MODE_BLEND_COVERAGE blend mode capability
2. Add "pre_multiplied_alpha" flag for Coverage case
3. Read the correct flag and set the DCN MPCC
pre_multiplied register bit (only on overlay plane)
