I'm interested in developing the RPi 4 into an open-source test pattern generator, particularly for use with HDR displays. It seems like a lot of what is needed overlaps with the effort to get HDR working in Kodi/LibreELEC.

Where is the work that popcornmix has done on the video driver to enable HDR output? Is it in the mainline Linux kernel somewhere?

I'm particularly interested in understanding the various registers that the GPU/HDMI peripheral exposes for setting the color format, bit depth, AVI info frames, etc. Are these documented anywhere?

Thanks!
