HDR support for Kod on Linux is an experimental work by lrusak and that branch hasn't been updated since January. He mentioned somewhere in this thread that HDR worked on his Vega M board. I get no HDR on my Athlon 200GE.

Any ideas?
I did not include AMD Mesa driver (radeonSI) in that build. because there is no point installing it on AMD. It's been confirmed by multiple users and by my own testing that HDR currently works only on Intel hardware.

will this still work for LSPCON NUCs?
Yes.

Updated build:
- Kodi 19 (dcec5f4) + HDR patches from lrusak + AV1 VAAPI HW decoding for TGL/RKL
- Linux 5.14-rc2
- Mesa 21.2.0-rc2
- FFmpeg 4.4 (de1132a) + patches from xbmc/ffmpeg + AV1 fixes.

Test if it fixed crashes for you.

Well, I'm out of ideas

In both logs I see that it is connected to a Marantz AVR.
Can you connect it directly to the TV, reboot, and post kodi.log?
-
I really have no idea why available modes are limited to 1080 for HDMI. Could be a driver or video bios table (VBT) issue. Try to update to the latest bios.
Also post kodi.log:
paste /storage/.kodi/temp/kodi.log

Has anyone any idea if there is a workaround to get deinterlacing work?
Disable "Allow using DRM PRIME decoder" in Player settings.

Is Mesa Intel Graphics (RKL GT1) a driver that should support 4K @ 60?
No, it is kernel i915 driver. Mesa is OpenGL/GLES stuff. Kernel 5.13 should properly support RKL, so I'm not sure what the issue is.
This latest image in post #751 crashes every 10-15 mins, and sometimes does a triple or quadruple crash loop.
No crashes at all on my box. Must be something specific to your NUC.
-
I tried this build on my NUC and it keeps rebooting every 5-10 mins. Gonna roll back.
Does it crash during playback?
EDID looks ok, no idea why Kodi is limiting to 1080. Try a clean install.

Run
paste /sys/class/drm/card0-HDMI-A-2/edid
and post the ix.io link here.

I compiled a new build with the following changes:
- AV1 VAAPI hardware decode (owners of TGL/RKL please test)
- added unmerged AV1 ffmpeg fixes:
github.com/intel-media-ci/ffmpeg/pull/403
github.com/intel-media-ci/ffmpeg/pull/412

But the maximum resolution is only 1080
Maybe some sort of EDID issue? Is it connected directly to the TV?
Dump the EDID data post it here:
Run via ssh:
tail /sys/class/drm/*/status
Look for the "connected" device. If it is e.g. "card0-HDMI-A-1". run:
paste /sys/class/drm/card0-HDMI-A-1/edid

I compiled another Kodi 19 GBM build.
- media-driver 29d5f8f. hopefully fixes RKL issues ( audiosat please test)
- Linux 5.13.1
- Mesa 21.1.4
- HDR patches from lrusak

I'm using raspbian os
Maybe better post this on raspbian os forum?
-
it says for AMD, would this still work?
It will work.
Can SMP or others confirm this build is not capable of Dolby TrueHD and DTS-HD MA passthrough?
It should be capable. However, some people reported issues with passthrough audio on Gemini Lake.
