Here's a refresh of Jyri's COLOR_ENCODING and COLOR_RANGE properties, and the i915 implementation I did on top. I tossed in a few core updates as well: plane state dump, and the BT.2020 constant luminance variant.
Apparently nouveau is already exposing a "iturbt_709" bool property which allows one to choose between BT.601 and BT.709 encodings, but given that we want at least BT.2020 in addition I don't think that property is good enough. Trying to implement it, and somehow extend it beyond BT.601 vs. BT.709 seems like wasted effort. Hence I think we should just ignore it and move on.
My userspace implementation in the form of intel ddx XV_COLORSPACE attribute: https://patchwork.freedesktop.org/patch/204696/
Any plans to get this going for -modesetting too? Distro's kinda stopped shipping -intel.
No plans by me since I don't use -modesetting. Volunteers welcome.
