4a36fcbaec drm/amd/display: correct stream LTE_340MCSC_SCRAMBLE value
[Why]
HDMI 2.0 requires scrambling under specific conditions. We refer to
stream property LTE_340MCSC_SCRAMBLE to determine whether en/dis
scrambling.
While creating stream for sink, we setup LTE_340MCSC_SCRAMBLE by
referring to edid_caps. However, dm_helpers_parse_edid_caps()
doesn't construct HDMI Forum block data for edid_caps.
Moreover, fill_stream_properties_from_drm_display_mode() aslo
unconsciously clear the LTE_340MCSC_SCRAMBLE flag.

[How]
Drm already provides drm_display_info to refer HDMI Forum vsdb info.
Set stream LTE_340MCSC_SCRAMBLE by drm_display_info and remove
memset in fill_stream_properties_from_drm_display_mode()

d832fc3b18 drm/amd/display: build up VSIF infopacket
[Why]
Didn't send VSIF infopacket when it's 4k mode defined in HDMI 1.4b.
For HDMI 1.4b, While displaying 4k modes, it should send VSP.

[How]
Call mod_build_hf_vsif_infopacket() function to build info frame
and send it.

1cb1d47741 drm/amd/display: Correct values in AVI infoframe
[Why]
While displaying 4k modes defined in HDMI1.4b, should set VIC to 0
and use VSP HDMI_VIC to indicate the mode.

[How]
Use functions defined in drm to set up the VIC correspondingly.

90d268741f drm/amd/display: Added pixel dynamic expansion control.
[Why]
To compare the crc of the framebuffer data at input of
display pipeline with the crc of the otg, we need to
disable pixel formatter's dynamic expansion feature during
crc capture and keep it enable in the normal operation.

[HOW]
Expose a new interface in DM and dc for pixel formatter
(fmt dynamic bitdepth expansion control). Interface control
the FMT_DYNAMIC_EXP_EN  bit, during crc capture keep
it disabled.

We need to manage the content protection property changes for

ENABLED/DESIRED status for different cases.

[How]
1. Attach the content_protection property

2. HDCP enable (UNDESIRED -> DESIRED)
	call into the module with the correct parameters to start
	hdcp. Set cp to ENABLED

3. HDCP disable (ENABLED -> UNDESIRED)
	Call the module to disable hdcp.

3. Handle Special cases	(Hotplug, S3, headless S3, DPMS)
	If already ENABLED: set to DESIRED on unplug/suspend/dpms,
	and disable hdcp

	Then on plugin/resume/dpms: enable HDCP

2ad0cdf9e2 drm/amd/display: set minimum abm backlight level
[Why]
A lot of the time, the backlight characteristic curve maps min backlight
to a non-zero value.
But there are cases where we want the curve to intersect at 0.
In this scenario even if OS never asks to set 0% backlight, the ABM
reduction can result in backlight being lowered close to 0.
This particularly can cause problems in some LED drivers, and in
general just looks like backlight is completely off.

[How]
Add default cap to disallow backlight from dropping below 1%
even after ABM reduction is applied.

452575c570 drm/amd/display: Lock the CRTC when setting CRC source
[Why]
We need to ensure that we're holding the lock on the CRTC when setting
the CRC source since we're modifying the CRTC state directly.

We also need to wait for any outstanding non-blocking commits to finish
so they aren't reading state that's potentially being modified -
non-blocking commits don't hold the CRTC lock while doing commit tail
work.

[How]
Lock the CRTC using its mutex. While holding the lock check if there's
any commit active on the CRTC - if there is, it's non-blocking and
we should wait until it's finished by waiting for hw_done to be
signaled since that's the last point where we touch CRTC state.

57638021b7 drm/amd/display: Split out DC programming for CRC capture
[Why]
Calling amdgpu_dm_crtc_set_crc_source in amdgpu_dm directly has the
consequence of adding additional vblank references or starting DPRX
CRC capture more than once without calling stop first.

Vblank references for CRC capture should be managed entirely by opening
and closing the CRC file from userspace.

Stream state also shouldn't be required on the CRC so we can close the
file after the CRTC has been disabled.

[How]
Do DC programming required for configuring CRC capture separately from
setting the source. Whenever we re-enable or reset a CRC this
programming should be reapplied.

CRC vblank reference handling in amdgpu_dm can be entirely dropped after
this.

Stream state also no longer needs to be required since we can just defer
the programming to when the stream is actually enabled.

7a23512595 drm/amd/display: Check return code for CRC drm_crtc_vblank_get
[Why]
The call to drm_crtc_vblank_get can fail if vblank is disabled and
we try to increment the reference.

Since drm_crtc_vblank_get internally drops the reference when it fails
it means the subsequent drm_crtc_vblank_put(...) when closing the file
drops a zero reference.

This was found via igt@kms_plane@pixel-format-pipe-A-planes.

[How]
Check the return code and return it on failure.

We wouldn't have been able to enable CRC reading anyway since vblank
wasn't enabled.

01c22997be drm/amd/display: Calculate bpc based on max_requested_bpc
[Why]
The only place where state->max_bpc is updated on the connector is
at the start of atomic check during drm_atomic_connector_check. It
isn't updated when adding the connectors to the atomic state after
the fact. It also doesn't necessarily reflect the right value when
called in amdgpu during mode validation outside of atomic check.

This can cause the wrong bpc to be used even if the max_requested_bpc
is the correct value.

[How]
Don't rely on state->max_bpc reflecting the real bpc value and just
do the min(...) based on display info bpc and max_requested_bpc.

caff0e6654 drm/amd/display: Block immediate flips for non-fast updates
[Why]
Underflow can occur in the case where we change buffer pitch, DCC state,
rotation or mirroring for a plane while also performing an immediate
flip. It can also generate a p-state warning stack trace on DCN1 which
is typically observed during the cursor handler pipe locking because of
how frequent cursor updates can occur.

[How]
Store the update type on each CRTC - every plane will have access to
the CRTC state if it's flipping. If the update type is not
UPDATE_TYPE_FAST then the immediate flip should be disallowed.

No changes to the target vblank sequencing need to be done, we just
need to ensure that the surface registers do a double buffered update.

[Why]
Pitch, DCC, rotation and mirroring can result in updates that are not
UPDATE_TYPE_FAST but UPDATE_TYPE_MED instead. DC needs dc_plane_info
and dc_plane_size to make this determination and we aren't currently
passing this into DC during atomic check.

Underflow (visible or non-visible) can occur if we don't validate this
correctly. This also will generally trigger p-state warnings, typically
via the cursor handler when locking.

[How]
Get the framebuffer tiling flags and generate the required structures
for DC in dm_determine_update_type_for_commit.

bd200d190f drm/amd/display: Don't replace the dc_state for fast updates
[Why]
DRM private objects have no hw_done/flip_done fencing mechanism on their
own and cannot be used to sequence commits accordingly.

When issuing commits that don't touch the same set of hardware resources
like page-flips on different CRTCs we can run into the issue below
because of this:

1. Client requests non-blocking Commit #1, has a new dc_state #1,
state is swapped, commit tail is deferred to work queue

2. Client requests non-blocking Commit #2, has a new dc_state #2,
state is swapped, commit tail is deferred to work queue

3. Commit #2 work starts, commit tail finishes,
atomic state is cleared, dc_state #1 is freed

4. Commit #1 work starts,
commit tail encounters null pointer deref on dc_state #1

In order to change the DC state as in the private object we need to
ensure that we wait for all outstanding commits to finish and that
any other pending commits must wait for the current one to finish as
well.

We do this for MEDIUM and FULL updates. But not for FAST updates, nor
would we want to since it would cause stuttering from the delays.

FAST updates that go through dm_determine_update_type_for_commit always
create a new dc_state and lock the DRM private object if there are
any changed planes.

We need the old state to validate, but we don't actually need the new
state here.

[How]
If the commit isn't a full update then the use after free can be
resolved by simply discarding the new state entirely and retaining
the existing one instead.

With this change the sequence above can be reexamined. Commit #2 will
still free Commit #1's reference, but before this happens we actually
added an additional reference as part of Commit #2.

If an update comes in during this that needs to change the dc_state
it will need to wait on Commit #1 and Commit #2 to finish. Then it'll
swap the state, finish the work in commit tail and drop the last
reference on Commit #2's dc_state.

43d10d30df drm/amd/display: Skip determining update type for async updates
[Why]
By passing through the dm_determine_update_type_for_commit for atomic
commits that can be done asynchronously we are incurring a
performance penalty by locking access to the global private object
and holding that access until the end of the programming sequence.

This is also allocating a new large dc_state on every access in addition
to retaining all the references on each stream and plane until the end
of the programming sequence.

[How]
Shift the determination for async update before validation. Return early
if it's going to be an async update.

e16e37efb4 drm/amd/display: Allow cursor async updates for framebuffer swaps
[Why]
We previously allowed framebuffer swaps as async updates for cursor
planes but had to disable them due to a bug in DRM with async update
handling and incorrect ref counting. The check to block framebuffer
swaps has been added to DRM for a while now, so this check is redundant.

The real fix that allows this to properly in DRM has also finally been
merged and is getting backported into stable branches, so dropping
this now seems to be the right time to do so.

[How]
Drop the redundant check for old_fb != new_fb.

With the proper fix in DRM, this should also fix some cursor stuttering
issues with xf86-video-amdgpu since it double buffers the cursor.

IGT tests that swap framebuffers (-varying-size for example) should
also pass again.

Send the notification via the audio component whenever we enable or

This is a bit delayed in when the notification actually occurs, however.
We wait until after all the programming is complete rather than sending
the notification mid sequence.

Particular care is needed for the get ELD callback since it can happen
outside the locking and fencing DRM does for atomic commits.

cf020d49b3 drm/amd/display: Rework CRTC color management
[Why]
To prepare for the upcoming DRM plane color management properties
we need to correct a lot of wrong behavior and assumptions made for
CRTC color management.

The documentation added by this commit in amdgpu_dm_color explains
how the HW color pipeline works and its limitations with the DRM
interface.

The current implementation does the following wrong:
- Implicit sRGB DGM when no CRTC DGM is set
- Implicit sRGB RGM when no CRTC RGM is set
- No way to specify a non-linear DGM matrix that produces correct output
- No way to specify a correct RGM when a linear DGM is used

We had workarounds for passing kms_color tests but not all of the
behavior we had wrong was covered by these tests (especially when
it comes to non-linear DGM). Testing both DGM and RGM at the same time
isn't something kms_color tests well either.

[How]
The specifics for how color management works in AMDGPU and the new
behavior can be found by reading the documentation added to
amdgpu_dm_color.c from this patch.

All of the incorrect cases from the old implementation have been
addressed for the atomic interface, but there still a few TODOs for
the legacy one.

Note: this does cause regressions for kms_color@pipe-a-ctm-* over HDMI.

The result looks correct from visual inspection but the CRC no longer
matches. For reference, the test was previously doing the following:

linear degamma -> CTM -> sRGB regamma -> RGB to YUV (709) -> ...

Now the test is doing:

linear degamma -> CTM -> linear regamma -> RGB to YUV (709) -> ...

39a4eb853f drm/amd/display: update DSC MST DP virtual DPCD peer device enumeration policy
[why]
Current policy assumes virtual DPCD peer device as
an individual MST branch device with 1 input and 1 output.
However this is only true for virtual DP-to-DP peer device.
In general there are three types of virtual DP peer devices.
1. Sink peer device with virtual DPCD.
2. Virtual DP-to-DP Peer device with virtual DPCD.
3. Virtual DP-to-HDMI Protocol Converter Peer Device with
Virtual DPCD.
So we should break the assumption and handle all three types.

[how]
DP-to-DP peer device will have virtual DPCD cap upstream.
Sink peer device will have virtual DPCD on the logical port.
Dp to HDMI protocol converter peer device will have virtual DPCD
on its converter port.
For DSC capable Synaptics non VGA port we workaround by enumerating
a virutal DPCD peer device on its upstream
even if it doesn't have one.

78ad75f8d7 drm/amd/display: Add power down display on boot flag
[Why]
Due to the generic introduction of seamless boot, the display is no
longer blanked upon boot. However, this causes corruption on some
systems that does not lock the memory in the non-secure boot case,
resulting in brief corruption on boot due to garbage being written into
the frame buffer.

[How]
Add a flag, read during DC init, to determine whether display should be
blanked on boot. Default to true.
