[Intel-gfx] [PATCH v2 00/12] drm/i915: Fix up DP DFP 4:2:0 handling more

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Currently we're failing to respect the sink's max TMDS clock
in the DP HDMI DFP code, and exceeding them means the sink
won't show a picture [1][2]. So let's improve the situation by
checking those limits, and generally fixing up a bunch things
in the deep color/4:2:0 related stuff for both native HDMI
and DP HDMI DFPs.

The end result is fairly unified apporach to this stuff on
both sides of the aisle. There's probably more we could try
to abstract to share even more code. But that will need a lot
of actual thought so leave it for later.

The high level algorithm is basically now:
for_each(respect TMDS clock limits, disrespect TMDS clock limits)
        for_each(YCbCr 4:2:0 only, RGB 4:4:4, YCbCr 4:2:0 also)
                for_each(12bpc,10bpc,8bpc)
                        compute_and_check_the_things
with some obvious tweaks for HDMI vs. DP specifics.

[Intel-gfx] [PATCH v2 01/12] drm/i915/dp: Extract intel_dp_tmds_clock_valid()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We're currently duplicating the DFP min/max TMDS clock checks
in .mode_valid() and .compute_config(). Extract a helper suitable
for both use cases.

[Intel-gfx] [PATCH v2 02/12] drm/i915/dp: Respect the sink's max TMDS clock when dealing with DP->HDMI DFPs

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Currently we only look at the DFPs max TMDS clock limit when
considering whether the mode is valid, or whether we can do
deep color. The sink's max TMDS clock limit may be lower than
the DFPs, so we need to account for it as well.

[Intel-gfx] [PATCH v2 03/12] drm/i915/dp: Extract intel_dp_has_audio()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Declutter intel_dp_compute_config() a bit by moving the
has_audio computation into a helper. HDMI already does the same thing.

[Intel-gfx] [PATCH v2 04/12] drm/i915/dp: s/intel_dp_hdmi_ycbcr420/intel_dp_is_ycbcr420/

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

intel_dp_hdmi_ycbcr420() does account for native DP 4:2:0
output as well, so lets rename it a bit.

[Intel-gfx] [PATCH v2 05/12] drm/i915/dp: Reorder intel_dp_compute_config() a bit

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Consolidate the double pfit call, and reorder things so that
intel_dp_output_format() and intel_dp_compute_link_config() are
back-to-back. They are intimately related, and will need to be
called twice to properly handle the "4:2:0 also" modes.

up the related variable names a bit.

[Intel-gfx] [PATCH v2 07/12] drm/i915/dp: Make intel_dp_output_format() usable for "4:2:0 also" modes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Hoist the drm_mode_is_420_only() from intel_dp_output_format()
into the caller. This will allow intel_dp_output_format() to be
reused for "4:2:0 also" modes.

[Intel-gfx] [PATCH v2 08/12] drm/i915/dp: Rework HDMI DFP TMDS clock handling

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Rework the HDMI DFP TMDS clock checks to also check at 8bpc.
Previously we only checked the deep color cases. But I suppose
a sink could potentially declare "4:2:0 also" modes that only
actually fit within its own limits when using 4:2:0. Even if
that is too nuts to be real there is no real harm in running
through the full checks for everything.

[Intel-gfx] [PATCH v2 09/12] drm/i915/dp: Add support for "4:2:0 also" modes for DP

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Currently we only support "4:2:0 also" modes on native HDMI.
Extend that support for DP as well.

With all the HDMI DFP TMDS clock handling sorted out this
is now going to work for both native DP and DP->HDMI
converters. As with native HDMI we first check if RGB
output is possible, and if not we try YCbCr 4:2:0 instead.

[Intel-gfx] [PATCH v2 10/12] drm/i915/dp: Duplicate native HDMI TMDS clock limit handling for DP HDMI DFPs

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

With native HDMI we allow the user to override the mode with
something that may not respect the downstream (sink,dual-mode adapter)
TMDS clock limits. Let's reuse the same logic for DP HDMI DFPs
so that behaviour is more or less uniform.

[Intel-gfx] [PATCH v2 11/12] drm/i915/dp: Fix DFP rgb->ycbcr conversion matrix

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Our YCbCr output is always supposed to be limited range BT.709.
That's what we send with native HDMI. The conn_state->colorspace
stuff is entirely independent of that and is not supposed to alter
the generated output in any way. If we want a way to do that then
we need a new proprty for it.

Make it so that the RGB->YCbCr conversion when performed by the
DPF will match the BT.709 we would transmit with native HDMI.

Looks Good to me.

[Intel-gfx] [PATCH v2 12/12] drm/i915/dp: Disable DFP RGB->YCbCr conversion for now

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We lack sufficient state tracking to figure out whether
we want the DFP to perform the RGB->YCbCr conversion for us
or not. So currently we are blindly just enabling that all the
time when supported by the DFP. That is nonsense. So until
we imporve our state tracking for this just disable the feature.

I think this will break 8k yuv pcon case as of now.
@Nautiyal, Ankit K Can we get that fixed. We will need 8k YUV from source due to
bandwidth constraints.

Rest of the series all looks nice and good.
