Deinterlacing does not work/cannot be enabled when DRM PRIME is enabled
It looks like the developer who was working on it ( Kwiboo) hasn't been active for almost 2 years. See his comment from 2019.
HDR is partially working without DRM PRIME. It seem to be limited to HEVC 24p videos. In fact, this limited HDR functionality now present in current Kodi master/LE nightly.
but my LG G1 never switched to HDR mode
Does it switch to HDR with my LE build?
I can't think of a reason why it wouldn't work, as long as you use Kodi-gbm.
is this still native HDMI
Yes.
What does Level Shifter do
"At extremely high data rate like this, signal quality drops significantly with extended board trace or cable length, making an additional retiming buffer necessary in many systems"
NUC 11 Essentials
NUC 11 Essentials = Jasper Lake SoC with inferior video processing features compared to Gemini Lake, e.g. no advanced MADI/MCDI HW deinterlacing.
Does this model use native HDMI or does it use LS-PCON???

PCON
support AV1??
Yes
I wonder what else is different comparing to regular nighties?
I used current Kodi master and linux kernel from drm-tip repo.
mind telling me which commit you're using?

I can't seem to boot your image on a NUC7 gemini lake
Does the nightly image boot?
I also compiled the tip of your gbm-bt2020 branch on an archlinux
I don't have a git branch named gbm-bt2020 and I know nothing about archlinux.
Updated build in post #1.
No issues here on Alder Lake.
One that I still can't get working is this.
Yes, this one doesn't work.
is it known that videos such as the ones here do not display with HDR?
That video plays with HDR here. "Allow using DRM PRIME decoder" must be enabled.
does this box have built in CEC
No
I have the same issue on my NUC11TN
Let them know this.
I think this is an issue with your TV (firmware?).
Intel driver default to 4K/24 12-bit RGB. Maybe your TV doesn't like this video mode.
Try to force 8 and 10 bit with proptest (copy it to /storage and chmod 755)
# systemctl stop kodi
# ./proptest
It should look something like this (values may be different for your box):
# ./proptest 326 connector 328 8 (this will force 8-bit for Connector 326 (HDMI-A-2))
# ./proptest 326 connector 328 10 (this will force 10-bit for Connector 326 (HDMI-A-2))
Then
# systemctl start kodi
and try to switch to 4k/24.
Try this build
Does 1080p 24Hz work? The issue is only with 4K 24Hz?
