[PATCH v2 0/2] Enabling content-type setting for HDMI displays.

[PATCH v2 0/2] Enabling content-type setting for HDMI displays.

[StanLis]

From: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com>

Added content type setting property to drm_connector(part 1)
and enabled transmitting it with HDMI AVI infoframes
for i915(part 2).

rev 2:
Moved helper function which attaches content type property
to the drm core, as was suggested.
Removed redundant connector state initialization.

  drm: content-type property for HDMI connector
  i915: content-type property for HDMI connector

Just use "Graphics", "Photo", etc. Same as is used in drivers/video/hdmi.c
for logging the AVI InfoFrame.

[PATCH v2 2/2] i915: content-type property for HDMI connector

[StanLis]

From: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com>

Added encoding of drm content_type property from
drm_connector_state within AVI infoframe in order to properly handle
external HDMI TV content-type setting.

Is the ITC bit set in the AVI InfoFrame? The content type bits are only valid if
the ITC bit is 1. And if there is no content type property, then ITC should be 0.

That's a good question, as I understood it is not set, however the HDMI 1.4 spec
says:

ITC CN1, CN0     Content Type
 0        0,  0          No Data

 1        0,  0          IT content

 X       0,  1          Photo
 X       1,  0          Cinema
 X       1,  1          Game

"X denotes don't care"

So I wonder, should I probably add additional property to control the itc bit?

Yeah, that's wrong in the HDMI Spec. The correct standard to use is the CEA (now CTA)
861. There it clearly defines that the CN bits are only valid if ITC=1.

I know, I'm in the CTA-861 working group :-)

I don't think anyone ever noticed this bug in the HDMI spec before (I didn't). The
2.1 HDMI spec kind of corrects it in Appendix G.1 where it copies the CTA-861-G
text.

Anyway, in V4L2 we implement this with an extra value "NO_ITC" which sets ITC to 0
and sets CN0 and CN1 to 0 as well:

https://hverkuil.home.xs4all.nl/spec/uapi/v4l/extended-controls.html#digital-video-control-ids

The NO_ITC case is usually used for YCbCr video encoding. Note that most displays will
just ignore the content type.

Regards,

	Hans

Wow, I wouldn't even assume that this spec is wrong. Probably then I need to add some way 
to manipulate an ITC bit also. I will have a look, however so far I didn't see any property responsible
for this.

[PATCH v2 0/2] Enabling content-type setting for HDMI displays.

[StanLis]

From: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com>

Added content type setting property to drm_connector(part 1)
and enabled transmitting it with HDMI AVI infoframes
for i915(part 2).

rev 2:
Moved helper function which attaches content type property
to the drm core, as was suggested.
Removed redundant connector state initialization.

Stanislav Lisovskiy (2):
  drm: content-type property for HDMI connector
  i915: content-type property for HDMI connector

[PATCH v2 2/2] i915: content-type property for HDMI connector

[StanLis]

From: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com>

Added encoding of drm content_type property from
drm_connector_state within AVI infoframe in order to properly handle
external HDMI TV content-type setting.
