60971b204c drm/amd/display: fix dm irq error message in gpu recover
[Why]
Variable adev->crtc_irq.num_types was initialized as the value of
adev->mode_info.num_crtc at early_init stage, later at hw_init stage,
the num_crtc changed due to the display pipe harvest on some SKUs,
but the num_types was not updated accordingly, that cause below error
in gpu recover.

  *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3

[How]
Defer the initialization of num_types to eliminate the error logs.

e47f1691ad drm/amd/display: Don't restrict bpc to 8 bpc
This will let us pass the kms_hdr.bpc_switch IGT
test.

The reason the bpc restriction was required is
historical. At one point in time we were not falling
back to a lower bpc when we didn't have enough
bandwidth for the maximum bpc reported by a display.
This meant that we couldn't enable some high refresh
modes unless we limitted the bpc.

Starting with this patch the issue is fixed:
commit cbd14ae7ea ("drm/amd/display: Fix
incorrectly pruned modes with deep color")

This patch implemented a fallback mechanism if mode
validation failed at the max bpc. This means users
now automatically get all modes that can be supported
by at least 6 bpc. The driver will enable the mode
with the highest possible bpc that is supported by
the display.

v2:
 - explain why this is no longer needed (Michel)
 - refer to commit that fixed bpc fallback (Michel)

d24b77e444 drm/amd/display: Pass proper parent for DM backlight device registration
The parent for the backlight device should be the drm-connector object,
not the PCI device.

Userspace relies on this to be able to detect which backlight class device
to use on hybrid gfx devices where there may be multiple native (raw)
backlight devices registered.

Specifically gnome-settings-daemon expects the parent device to have
an "enabled" sysfs attribute (as drm_connector devices do) and tests
that this returns "enabled" when read.

This aligns the parent of the backlight device with i915, nouveau, radeon.
Note that drivers/gpu/drm/amd/amdgpu/atombios_encoders.c also already
uses the drm_connector as parent, only amdgpu_dm.c used the PCI device
as parent before this change.

Note this is marked as a RFC because I don't have hw to test, so this
has only been compile tested! If someone can test this on actual
hw which hits the changed code path that would be great.

80c6d6804f 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

[Why]
We only allowed 1 overlay plane. But now some ASICS can support multiple
overlay planes.

[How]
Use max_slave_planes as the number of overlays we can support.

Also since we cannot draw cursor over a video plane, we need to make
sure that we reject commits where the topmost plane is a video plane
(overlay only).

e761cc2094 drm/display/dp_mst: Handle old/new payload states in drm_dp_remove_payload()
Atm, drm_dp_remove_payload() uses the same payload state to both get the
vc_start_slot required for the payload removal DPCD message and to
deduct time_slots from vc_start_slot of all payloads after the one being
removed.

The above isn't always correct, as vc_start_slot must be the up-to-date
version contained in the new payload state, but time_slots must be the
one used when the payload was previously added, contained in the old
payload state. The new payload's time_slots can change vs. the old one
if the current atomic commit changes the corresponding mode.

This patch let's drivers pass the old and new payload states to
drm_dp_remove_payload(), but keeps these the same for now in all drivers
not to change the behavior. A follow-up i915 patch will pass in that
driver the correct old and new states to the function.

variety of platform configurations (DRAM bandwidth, etc.) and
a variety of monitors, but so far have not been able to.  We
disabled S/G display on a number of platforms to address this

blank displays when there is memory pressure or no displays
at all on systems with limited carveout (e.g., Chromebooks).

This is a very trivial code clean-up related to commit 5468c36d62
("drm/amd/display: Filter Invalid 420 Modes for HDMI TMDS"). This commit
added a validation on driver probe to prevent invalid TMDS modes, but one
of the fake properties (swizzle) ended-up causing a warning on driver
probe; was reported here: https://gitlab.freedesktop.org/drm/amd/-/issues/2264.

It was fixed by commit a1cbe6916f ("drm/amd/display: patch cases with
unknown plane state to prevent warning"), but the validation code had
a double variable assignment, which we hereby remove. Also, the fix relies
in the dcn2{0,1}patch_unknown_plane_state() callbacks, so while at it we
took the opportunity to perform a small code clean-up in such routines.

1. If DP1.2 hub where gives reduced link bw and no dsc support.
2. If less than 4-lane configuration where gives reduced bw.
3. If FRL PCON enabled for asic.
4. Track MST sink count.

0f5f1ee45f drm/amd/display: Fix timing not changning when freesync video is enabled
[Why&How]
Switching between certain modes that are freesync video modes and those
are not freesync video modes result in timing not changing as seen by
the monitor due to incorrect timing being driven.

The issue is fixed by ensuring that when a non freesync video mode is
set, we reset the freesync status on the crtc.

in immature wake up to completion.

c84ff24a77 drm/amd/display: Pass DSC slice height to PSR FW
[Why]
When DSC is enabled, the PSRSU seletive update region
must be multiple number of DSC slice height number.
The original solution is to overwrite the SU Y granularity
by DSC slice height in DAL driver. However, the size
of the SU Y granularity variable only has 8 bytes
and the DSC slice height may over the 8 bytes size.

[How]
Instead of overwriting the SU Y granularity value,
add a new DSC slice height pararmeter and pass it
to DMUB PSRSU FW. The PSRSU FW will refer to the
DSC slice height value and extend the SU region.

[why]
link component contains three sub folders:

accessories - utilities for improving testability, logging or tracing, doesn't impact
end user use cases.

protocols - specs defined protocols used in end user use cases

hwss - hwss owned link_hwss object, served as an abstraction layer in hwss to
access various types of encoder/phy/dpia endpoints in a unified interface.

sooner we will have files directly under link folder one for the implementation of
each major link behavior such as link_create, link_detect, link_validate
and link_set_dpms.

ea38dd57b0 drm/amdgpu/display/mst: limit payload to be updated one by one
[Why]
amdgpu expects to update payload table for one stream one time
by calling dm_helpers_dp_mst_write_payload_allocation_table().
Currently, it get modified to try to update HW payload table
at once by referring mst_state.

[How]
This is just a quick workaround. Should find way to remove the
temporary struct dc_dp_mst_stream_allocation_table later if set
struct link_mst_stream_allocatio directly is possible.

c689e1e362 drm/amdgpu/display/mst: Fix mst_state->pbn_div and slot count assignments
Looks like I made a pretty big mistake here without noticing: it seems when
I moved the assignments of mst_state->pbn_div I completely missed the fact
that the reason for us calling drm_dp_mst_update_slots() earlier was to
account for the fact that we need to call this function using info from the
root MST connector, instead of just trying to do this from each MST
encoder's atomic check function. Otherwise, we end up filling out all of
DC's link information with zeroes.

So, let's restore that and hopefully fix this DSC regression.

7eaef1163b drm/amd/display: set allow_freesync parameter in DM
[Why&how]
There are cases where VRR is possible but not enabled. If allow_freesync
parameter is not set, SubVP logic defaults to checking only the ignore MSA
parameter that is always set if display is DRR capable, which breaks the system
while trying to enable SubVP on multi monitor configs where freesync
does not work due to Xorg limitation.

SubVP uses allow_freesync parameter to check if SubVP + DRR case can be executed.
