Re: [RFC 0/5] HDMI 2.0+ video modes handling in DRM core

[Sharma, Shashank]

I realized it was too early to search that in dri-devel last night, I 
guess it takes some time to sync.


Now I can see them all :)

Also, I am planning to publish a series for YUV 420 handling, where I have 
re-used one of your patch to parse YUV 420 block, with some modifications :-).

Hi all,

This is a RFC series that aims to collect comments regarding the
handling of HDMI 2.0+ video modes and features in the DRM core.

Some of the HDMI 2.0 features are already implemented and only affect
kernel drivers (SDCD for example). There are some features, though,
which can, and will, affect userspace.

It is clear that userspace can't be broken, so, based on previous
discussions I started implementing a "HDMI 2.0+ knob" which can be set
by userspace to enable HDMI 2.0+ features.

For now this only limits the exposing of the video modes defined in
CEA-861-F, but it can be extended adding, for example, YCbCr 4:2:0.

Please do not see this as a formal patch as this wasn't even compiled
tested but, please, feel free to comment :)

NOTE: The adding of the new video modes timings was originally done by
Shashank Sharma <shashank.sha...@intel.com> so, credit to him. I
modified it a little bit (added the HDMI 2.0+ flag) and I don't know
if I should add his signed-off-by as it was modified.

RE: [RFC 0/5] HDMI 2.0+ video modes handling in DRM core

[Sharma, Shashank]

Hi Jose, 
I can't find the other patches of this series in dri patchwork, am I missing 
something ?

Also, I am planning to publish a series for YUV 420 handling, where I have 
re-used one of your patch to parse YUV 420 block, with some modifications :-).

Shashank
