[PATCH 00/11] drm/i915/dp: Few MTL/DSC and a UHBR monitor fix

[Imre Deak]

This patchset fixes a few MTL/DSC 1.2 related issues and adds a
workaround for the native 5k@60Hz uncompressed mode on a MediaTek/Dell
UHBR monitor, force-enabling DSC on it as required, similarly to the
existing HBLANK expansion quirk for Synaptics hubs.

[PATCH 01/11] drm/i915/dp: Fix DSC line buffer depth programming

[Imre Deak]

Fix the calculation of the DSC line buffer depth. This is limited both
by the source's and sink's maximum line buffer depth, but the former one
was not taken into account. On all Intel platform's the source's maximum
buffer depth is 13, so the overall limit is simply the minimum of the
source/sink's limit, regardless of the DSC version.

This leaves the DSI DSC line buffer depth calculation as-is, trusting
VBT.

On DSC version 1.2 for sinks reporting a maximum line buffer depth of 16
the line buffer depth was incorrectly programmed as 0, leading to a
corruption in color gradients / lines on the decompressed screen image.

Re: [PATCH 01/11] drm/i915/dp: Fix DSC line buffer depth programming

[Manasi Navare]

Hi Imre,

Thanks for the DSC fixes.
Would the line buf depth calculation that was getting set to 0 impact
DSC on all platforms
or was this issue only specific to MTL and was getting set correctly
with older platforms?
We didnt notice any DSC issues/corruptions with ADL based systems.

The actual change makes sense, just want to confirm if this applies to
all platforms or any particular?
With that clarification:

Only those configs are affected where both the source and the sink supports
DSC1.2, so ADL is not affected.

Yes, that makes sense.

The change will make a difference only on MTL+.

Hi Maarten, Thomas, Maxime,

are you ok to merge the DRM DP-DSC/MST changes in patches 1, 7-9, 11 via
drm-intel-next?

[PATCH 02/11] drm/i915/dp_mst: Fix symbol clock when calculating the DSC DPT bpp limit

[Imre Deak]

The expected link symbol clock unit when calculating the DSC DPT bpp
limit is kSymbols/sec, aligning with the dotclock's kPixels/sec unit
based on the crtc clock. As opposed to this port_clock is used - which
has a 10 kbits/sec unit - with the resulting symbol clock in 10
kSymbols/sec units (disregarding the rounding error for the 13.5Gbps
rate). Fix the calculation using the expected 10x factor.

Is this correct Symbol clock calculation not needed for UHBR support
on platforms with DISPLAY_VER = 14 (MTL)?

[PATCH 03/11] drm/i915/dp_mst: Fix BW limit check when calculating DSC DPT bpp

[Imre Deak]

The DSC DPT bpp limit check should only fail if the available DPT BW is
less than the required BW, fix the check accordingly.

[PATCH 04/11] drm/i915/dp_mst: Account for channel coding efficiency in the DSC DPT bpp limit

[Imre Deak]

The DSC DPT interface BW limit check should take into account the link
clock's (aka DDI clock in bspec) channel coding efficiency overhead.
Bspec doesn't mention this, however this matches how the link BW limit
is checked (that is the BW limit on wire as opposed to the above DPT
limit) for which Bspec doesn't mention the overhead either.

This fixes the DPT bpp limit for at least the 5k@60Hz/DSC mode on a Dell
UHBR monitor/link I tested.

Bspec: 49259

[PATCH 05/11] drm/i915/dp_mst: Account with the DSC DPT bpp limit on MTL

[Imre Deak]

The DPT/DSC bpp limit should be accounted for on MTL platforms as well,
do so.

Should this be DISPLAY_VER() <= 14 to include MTL?

For DISPLAY_VER 20, is there another check?

in Bspec:68912 it mentions output bpp * pixel clock < DDICLK * 144 bits

Please ignore the above, I see you are addressing this in next patch.

The actual change is the DISPLAY_VER() < 20 below, which is the usual
way in the driver (AFAIU) to check for an upper bound.

Yes LNL is different, but there this DPT limit should never be a
bottleneck. Ville has an idea to abstract this more, but this patchset
keeps things as-is, skipping the check on LNL+.

Agreed. Bspec indeed mentions the same thing, and its mentioned 
appropriately in the next patch.

Hi Imre,

While we are adding these checks here for DSC for MST, I see that in
intel_dp_mst_mode_valid_ctx() we still check against DISPLAY_VER() >
10 for checking for DSC where as in all other places we rely on
runtime has_dsc and check for HAS_DSC(), can we fix that and use
HAS_DSC() in this function as well as part of this series that in
general fixes some DSC issues?

The check in intel_dp_mst_check_constraints() this patch changes is not
about whether a platform supports DSC or not, rather if the platform has
a DSC/DPT interface limit that needs to be checked. The caller has
already determined that DSC is supported by the platform and it's needed
for the given mode being computed (dsc==true).

[PATCH 06/11] drm/i915/dp_mst: Sanitize calculating the DSC DPT bpp limit

[Imre Deak]

Instead of checking each compressed bpp value against the maximum
DSC/DPT bpp, simplify things by calculating the maximum bpp upfront and
limiting the range of bpps looped over using this maximum.

While at it add a comment about the origin of the DSC/DPT bpp limit.

Re: [PATCH 06/11] drm/i915/dp_mst: Sanitize calculating the DSC DPT bpp limit

[Manasi Navare]

Hi Imre,

Would this impact/fix DSC functionality on ADL based platforms as well
or will this change only impact platforms that support UHBR?

The related DPT limit changes in this patchset make a difference only
on platforms supporting UHBR, so DG2 and MTL+.

[PATCH 10/11] drm/i915/dp_mst: Make HBLANK expansion quirk work for logical ports

[Imre Deak]

The DPCD OUI of the logical port on a Dell UHBR monitor - on which the
AUX device is used to enable DSC - is all 0. To detect if the HBLANK
expansion quirk is required for this monitor use the OUI of the port's
parent instead.

Since in the above case the DPCD of both the logical port and the parent
port reports being a sink device (vs. branch device) type, read the
proper sink/branch OUI based on the DPCD device type.

This is required by a follow-up patch enabling the quirk for the above
Dell monitor.

As I understand, we are setting connector->mst_port as intel_dp, in the 
caller intel_dp_add_mst_connector so its unlikely that aux can be NULL, 
but do you see if we need to check for aux?

Yes, intel_connector::mst_port (always) points to the intel_dp of the
MST root port, and aux will be always initialized for all the registered
DP encoders/intel_dps; so mst_port->aux will always point to a
valid/non-NULL AUX device. (In any case above we take the address of
intel_dp::aux, which can't be NULL.)

[PATCH 11/11] drm/i915/dp_mst: Enable HBLANK expansion quirk for UHBR rates

[Imre Deak]

Enabling the 5k@60Hz uncompressed mode on the MediaTek/Dell U3224KBA
monitor results in a blank screen, at least on MTL platforms on UHBR
link rates with some (<30) uncompressed bpp values. Enabling compression
fixes the problem, so do that for now. Windows enables DSC always if the
sink supports it and forcing it to enable the mode without compression
leads to the same problem above (which suggests a panel issue with
uncompressed mode).

The same 5k mode on non-UHBR link rates is not affected and lower
resolution modes are not affected either. The problem is similar to the
one fixed by the HBLANK expansion quirk on Synaptics hubs, with the
difference that the problematic mode has a longer HBLANK duration. Also
the monitor doesn't report supporting HBLANK expansion; either its
internal MST hub does the expansion internally - similarly to the
Synaptics hub - or the issue has another root cause, but still related
to the mode's short HBLANK duration. Enable the quirk for the monitor
adjusting the detection for the above differences.
