[Why & How]
To organize the edp power control a bit:
1. add flag in dc_link to indicate dc to skip all implicit eDP power control.
2. add edp_set_panel_power link service for DM to call.

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.

[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.

[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.

The 6.75 GBps link rate is part of the new eDP specification
version 1.5 is going to be supported in the future.
Since this standard is very new and there are no existing 6.75 GBps
panels on the market yet, we should put a condition in the driver
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

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.

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

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.

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

[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.

[Description]
- Incorporate FW delays as port of max VTOTAL calculated for
SubVP + DRR cases (since it is part of the microschedule).
- 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.

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.

[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.

[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.

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.

Add details about color correction capabilities and explain a bit about
differences between DC hw generations and also how they are mapped
between DRM and DC interface. Two schemas for DCN 2.0 and 3.0 (converted
to svg from the original png) is included to illustrate it. They were
obtained from a discussion[1] in the amd-gfx mailing list.

In the DCN code, we can find some references to three different pipe
split policies but no clear description. This commit adds some
kernel-doc that explains more about these options and a little bit of
their impact.
