4f76da2318 drm/amd/display: Correct I2C register offset
[Why]
I2C register name starts with 1, unlike other registers that start with
0. This creates a problem with the new register macro refactoring when
I2C HW objects are created in an array.

[How]
Correct I2C register offset by making a new macro to account for array
offset.

17529ea2ac drm/amd/display: Optimizations for DML math
[why]
Conditionals in the DML basic math functions significantly impact mode
enumeration.

[how]
Remove conditionals for floor/ceil operations which are used frequently
in DML and add an assertion for invalid callers using zero granuality.
Fix existing callers that rely on 0 granularity.

c0f50c5de9 drm/amdgpu: Register ACPI video backlight when skipping amdgpu backlight registration
Typically the acpi_video driver will initialize before amdgpu, which
used to cause /sys/class/backlight/acpi_video0 to get registered and then
amdgpu would register its own amdgpu_bl# device later. After which
the drivers/acpi/video_detect.c code unregistered the acpi_video0 device
to avoid there being 2 backlight devices.

This means that userspace used to briefly see 2 devices and the
disappearing of acpi_video0 after a brief time confuses the systemd
backlight level save/restore code, see e.g.:
https://bbs.archlinux.org/viewtopic.php?id=269920

To fix this the ACPI video code has been modified to make backlight class
device registration a separate step, relying on the drm/kms driver to
ask for the acpi_video backlight registration after it is done setting up
its native backlight device.

Add a call to the new acpi_video_register_backlight() when amdgpu skips
registering its own backlight device because of either the firmware_flags
or the acpi_video_get_backlight_type() return value. This ensures that
if the acpi_video backlight device should be used, it will be available
before the amdgpu drm_device gets registered with userspace.

e0b859cf7c drm/amd/display: Re-initialize viewport after pipe merge
[Why]
Pipes get merged in preparation for SubVP but if they don't get used, and
are in ODM or some other multi pipe config, it would calculate the
voltage level with a viewport of just one pipe from when they were split
resulting in too low of a voltage level.

[How]
Made it so that the viewport and other timing settings get rebuilt and re-
initialized after the pipe merge, before calculating the voltage level so it
would calculate it correctly.

4b91ac9e38 drm/amd/display: Fix primary EDP link detection
[HOW&WHY]
EDP link detection must
be updated to support a primary EDP with a
link index of greater than 0.

* SWDEV-342936 - dc: DSC bringup for SAG 1.5

[WHY]
SmartAccess Graphics 1.5 (a.k.a SmartMux 1.5)
requires seamless switching between GPUs
with DSC enabled.

[HOW]
Moved DSC programming to
apply_single_control_ctx_to_hw before the stream
enablement logic to ensure the CRC checker provides valid
values for non-black frames
allowing the system to come out of forced PSR on
d2i.

Added additional logic to both generate a black
frame through setVisibility calls and keep track
of the CRCs values for this black frame when
coming out of forced PSR.

Updating logic for DalRegKey_DisableDSC to disable
DSC on EDP and all ports for systems.

[CLEANED]
dc: Moved DSC programming to before stream enablement

[HOW&WHY]
Moved DSC programming to
apply_single_control_ctx_to_hw before the stream
enablement logic.

da11ef8329 drm/amdgpu: Don't register backlight when another backlight should be used (v3)
Before this commit when we want userspace to use the acpi_video backlight
device we register both the GPU's native backlight device and acpi_video's
firmware acpi_video# backlight device. This relies on userspace preferring
firmware type backlight devices over native ones.

Registering 2 backlight devices for a single display really is
undesirable, don't register the GPU's native backlight device when
another backlight device should be used.

Changes in v2:
- To avoid linker errors when amdgpu is builtin and video_detect.c is in
  a module, select ACPI_VIDEO and its deps if ACPI is enabled.
  When ACPI is disabled, ACPI_VIDEO is also always disabled, ensuring
  the stubs from acpi/video.h will be used.

Changes in v3:
- Use drm_info(drm_dev, "...") to log messages
- ACPI_VIDEO can now be enabled on non X86 too,
  adjust the Kconfig changes to match this.

4d07b0bc40 drm/display/dp_mst: Move all payload info into the atomic state
Now that we've finally gotten rid of the non-atomic MST users leftover in
the kernel, we can finally get rid of all of the legacy payload code we
have and move as much as possible into the MST atomic state structs. The
main purpose of this is to make the MST code a lot less confusing to work
on, as there's a lot of duplicated logic that doesn't really need to be
here. As well, this should make introducing features like fallback link
retraining and DSC support far easier.

Since the old payload code was pretty gnarly and there's a Lot of changes
here, I expect this might be a bit difficult to review. So to make things
as easy as possible for reviewers, I'll sum up how both the old and new
code worked here (it took me a while to figure this out too!).

The old MST code basically worked by maintaining two different payload
tables - proposed_vcpis, and payloads. proposed_vcpis would hold the
modified payload we wanted to push to the topology, while payloads held the
payload table that was currently programmed in hardware. Modifications to
proposed_vcpis would be handled through drm_dp_allocate_vcpi(),
drm_dp_mst_deallocate_vcpi(), and drm_dp_mst_reset_vcpi_slots(). Then, they
would be pushed via drm_dp_mst_update_payload_step1() and
drm_dp_mst_update_payload_step2().

Furthermore, it's important to note how adding and removing VC payloads
actually worked with drm_dp_mst_update_payload_step1(). When a VC payload
is removed from the VC table, all VC payloads which come after the removed
VC payload's slots must have their time slots shifted towards the start of
the table. The old code handles this by looping through the entire payload
table and recomputing the start slot for every payload in the topology from
scratch. While very much overkill, this ends up doing the right thing
because we always order the VCPIs for payloads from first to last starting
timeslot.

It's important to also note that drm_dp_mst_update_payload_step2() isn't
actually limited to updating a single payload - the driver can use it to
queue up multiple payload changes so that as many of them can be sent as
possible before waiting for the ACT. This is -technically- not against
spec, but as Wayne Lin has pointed out it's not consistently implemented
correctly in hubs - so it might as well be.

drm_dp_mst_update_payload_step2() is pretty self explanatory and basically
the same between the old and new code, save for the fact we don't have a
second step for deleting payloads anymore -and thus rename it to
drm_dp_mst_add_payload_step2().

The new payload code stores all of the current payload info within the MST
atomic state and computes as much of the state as possible ahead of time.
This has the one exception of the starting timeslots for payloads, which
can't be determined at atomic check time since the starting time slots will
vary depending on what order CRTCs are enabled in the atomic state - which
varies from driver to driver. These are still stored in the atomic MST
state, but are only copied from the old MST state during atomic commit
time. Likewise, this is when new start slots are determined.

Adding/removing payloads now works much more closely to how things are
described in the spec. When we delete a payload, we loop through the
current list of payloads and update the start slots for any payloads whose
time slots came after the payload we just deleted. Determining the starting
time slots for new payloads being added is done by simply keeping track of
where the end of the VC table is in
drm_dp_mst_topology_mgr->next_start_slot. Additionally, it's worth noting
that we no longer have a single update_payload() function. Instead, we now
have drm_dp_mst_add_payload_step1|2() and drm_dp_mst_remove_payload(). As
such, it's now left it up to the driver to figure out when to add or remove
payloads. The driver already knows when it's disabling/enabling CRTCs, so
it also already knows when payloads should be added or removed.

Changes since v1:
* Refactor around all of the completely dead code changes that are
  happening in amdgpu for some reason when they really shouldn't even be
  there in the first place… :\
* Remove mention of sending one ACT per series of payload updates. As Wayne
  Lin pointed out, there are apparently hubs on the market that don't work
  correctly with this scheme and require a separate ACT per payload update.
* Fix accidental drop of mst_mgr.lock - Wayne Lin
* Remove mentions of allowing multiple ACT updates per payload change,
  mention that this is a result of vendors not consistently supporting this
  part of the spec and requiring a unique ACT for each payload change.
* Get rid of reference to drm_dp_mst_port in DC - turns out I just got
  myself confused by DC and we don't actually need this.
Changes since v2:
* Get rid of fix for not sending payload deallocations if ddps=0 and just
  go back to wayne's fix

a76eb4297f drm/display/dp_mst: Add helpers for serializing SST <-> MST transitions
There's another kind of situation where we could potentially race with
nonblocking modesets and MST, especially if we were to only use the locking
provided by atomic modesetting:

* Display 1 begins as enabled on DP-1 in SST mode
* Display 1 switches to MST mode, exposes one sink in MST mode
* Userspace does non-blocking modeset to disable the SST display
* Userspace does non-blocking modeset to enable the MST display with a
  different CRTC, but the SST display hasn't been fully taken down yet
* Execution order between the last two commits isn't guaranteed since they
  share no drm resources

We can fix this however, by ensuring that we always pull in the atomic
topology state whenever a connector capable of driving an MST display
performs its atomic check - and then tracking CRTC commits happening on the
SST connector in the MST topology state. So, let's add some simple helpers
for doing that and hook them up in various drivers.

v2:
* Use intel_dp_mst_source_support() to check for MST support in i915, fixes
  CI failures

ffac972193 drm/display/dp_mst: Don't open code modeset checks for releasing time slots
I'm not sure why, but at the time I originally wrote the find/release time
slot helpers I thought we should avoid keeping modeset tracking out of the
MST helpers. In retrospect though there's no actual good reason to do
this, and the logic has ended up being identical across all the drivers
using the helpers. Also, it needs to be fixed anyway so we don't break
things when going atomic-only with MST.

So, let's just move this code into drm_dp_atomic_release_time_slots() and
stop open coding it.

a5c2c0d164 drm/display/dp_mst: Add nonblocking helpers for DP MST
As Daniel Vetter pointed out, if we only use the atomic modesetting locks
with MST it's technically possible for a driver with non-blocking modesets
to race when it comes to MST displays - as we make the mistake of not doing
our own CRTC commit tracking in the topology_state object.

This could potentially cause problems if something like this happens:

* User starts non-blocking commit to disable CRTC-1 on MST topology 1
* User starts non-blocking commit to enable CRTC-2 on MST topology 1

There's no guarantee here that the commit for disabling CRTC-2 will only
occur after CRTC-1 has finished, since neither commit shares a CRTC - only
the private modesetting object for MST. Keep in mind this likely isn't a
problem for blocking modesets, only non-blocking.

So, begin fixing this by keeping track of which CRTCs on a topology have
changed by keeping track of which CRTCs we release or allocate timeslots
on. As well, add some helpers for:

* Setting up the drm_crtc_commit structs in the ->commit_setup hook
* Waiting for any CRTC dependencies from the previous topology state

v2:
* Use drm_dp_mst_atomic_setup_commit() directly - Jani

df78f7f660 drm/display/dp_mst: Call them time slots, not VCPI slots
VCPI is only sort of the correct term here, originally the majority of this
code simply referred to timeslots vaguely as "slots" - and since I started
working on it and adding atomic functionality, the name "VCPI slots" has
been used to represent time slots.

Now that we actually have consistent access to the DisplayPort spec thanks
to VESA, I now know this isn't actually the proper term - as the
specification refers to these as time slots.

Since we're trying to make this code as easy to figure out as possible,
let's take this opportunity to correct this nomenclature and call them by
their proper name - timeslots. Likewise, we rename various functions
appropriately, along with replacing references in the kernel documentation
and various debugging messages.

It's important to note that this patch series leaves the legacy MST code
untouched for the most part, which is fine since we'll be removing it soon
anyhow. There should be no functional changes in this series.

v2:
* Add note that Wayne Lin from AMD suggested regarding slots being between
  the source DP Tx and the immediate downstream DP Rx

dml_wrapper* files were removed in commit 01b537eeb0
("drm/amd/display: Remove unused code"), as they are not used anywhere.
However, the header file wasn't removed, so remove the header as well.

6ae0632d17 drm/amd/display: fix overflow on MIN_I64 definition
The definition of MIN_I64 in bw_fixed.c can cause gcc to whinge about
integer overflow, because it is treated as a positive value, which is
then negated. The temporary positive value is not necessarily
representable.

This causes the following warning:
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/calcs/bw_fixed.c:30:19:
warning: integer overflow in expression ‘-9223372036854775808’ of type

0a8c91d7b6 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.

19f7b83344 drm/amd/display: Update clock table policy for DCN314
[Why & How]
Depending on how the clock table is constructed from PMFW we can run
into issues where we don't think we have enough bandwidth available
due to FCLK too low - eg. when the FCLK table contains invalid entries
or a single entry.

We should always pick up the maximum clocks for each state as a final
state in this case to prevent validation from failing if the table is
malformed.

We should also contain sensible defaults in the case where values
are invalid.

Redfine the clock table structures by adding a 314 prefix to make
debugging these issues easier by avoiding symbol name clashes.

Overall this policy more closely aligns to how we did things for 315,
but because of how the voltage rail is setup we should favor keeping
DCFCLK low rather than DISPCLK or DPPCLK - so use the max for those
in every entry.

dd49c07f3a drm/amd/display: Modify header inclusion pattern
[Why]
Recent backport from opensource broke the Nightly tool build
that tests DC and DML for bugs and regressions. This was
because the backport had a header inclusion that was not
consistent with the AMD style of including headers was allowed
to be merged back in DML code that caused tool compilation
failures.

[How]
Modify the way in which the header file in included so that it
is consistent with AMD style of including headers. This then
automatically fixes the tool compilation process and also
helps maintain the code quality and consistency.

BIOS functions for transmitter/encoder control take pixel clock in kHz
increments, whereas the function for setting the pixel clock is in 100Hz
increments. Setting pixel clock to a value that is not on a kHz boundary
will cause the issue.

[How]
Round pixel clock down to nearest kHz in 10/12-bpc cases.

e0df49b304 drm/amd/display: reverted limiting vscsdp_for_colorimetry and ARGB16161616 pixel format addition
[WHY]
Limiting vscsdp_for_colorimetry for YCbCr420/BT2020 resulted in red/green
point failures in HDR10 DTN tests. The re-implementation of ARGB16161616
was to fix this however it did not actually fix this issue but a side effect of the
issue.

[HOW]
Change ARGB16161616 pixel format to 26.

a61bb3422e drm/amdgpu_dm: Rely on split out luminance calculation function
Luminance range calculation was split out into drm_edid.c and is now
part of edid parsing. Rely on values calculated during edid parsing and
use these for caps->aux_max_input_signal and caps->aux_min_input_signal.

v2: Use values calculated during edid parsing

acc96ae0d1 drm/amd/display: set panel orientation before drm_dev_register
To set the panel orientation property with quirk, we need the mode size
provided by EDID. This info is available after EDID is read by dc_link_detect()
and updated by amdgpu_dm_update_connector_after_detect(). The detection
happens at driver load in amdgpu_dm_initialize_drm_device() and,
therefore, we can get modes and set panel orientation before
drm_dev_register() to avoid DRM warns on creating the connector property
after device registration:

[Why]
After TDR recovery, eDP and USB4 display does not light up. Because
dmub outbox notifications are not enabled after dmub reload and link
encoder assignments for the streams are not cleared before dc state
reset.

[How]
- Dmub outbox notification is enabled after tdr recovery by issuing
  inbox command to dmub.
- Link encoders for the streams are unassigned before dc state reset.

2de09ce41f drm/amd/display: fix CAB allocation for multiple displays
[Why & How]
When multiple displays are used, the underlying framebuffers could be
two separate framebuffers, or a single large framebuffer. Fix the
calculation logic for CAB to account for large framebuffer. Current
logic assumes that any FB that the plane points to are independent. When
a single FB is used on the system, this does 2 times allocation.

Add a check to prevent duplicate allocation by checking if the base
addresses are the same, and then ensuring that the if we allocate using
the pitch, whole of the other fbs will be accounted for in the first
allocation.
