All Tiger Lake chips have the same (Gen12) GPU. The difference is only a number of enabled EUs (48 on lower end Celeron 6305).

I googled the picture of the Brix Gemini Lake mainboard. For some bizarre reason, it has PTN3366 HDMI level shifter (a chip near the HDMI port).

That chip is not HDMI 2.0 compliant and probably causing these issues.

The option to select the de-interlacing mode is greyed out, is this by design?

RE: Intel true 10bits/HEVC/HDR support... ?

It does indeed now work. I didn't notice any obvious difference.

Updated image with HDR for Gemini Lake hardware (Tiger Lake and DG1 probably work too, if anyone has that already).

- Current Kodi master (a2b4a43)

- Current LE master (7badb00)

- Linux kernel 5.10.11

- Kodi and ffmpeg HDR commits from here and here

"UHD Graphics" on Tiger Lake Celerons is the same Gen12 GPU as on i3/i5/i7 Tiger Lakes, just with some EUs disabled. Sure it will work.

It's not yet clear if the boards with a non-native HDMI 2.0 port (DP-to-HDMI 2.0 converter chip aka LSPCON) will be able to do HDR on Linux. In any case there is no reason to buy one of those.

Intel Gemini Lake (e.g. Celeron J4105/J4125) or the new Tiger Lake (e.g. Celeron 6305) are the only x86 hardware worth considering for HDR on LibreELEC.

AMD APUs with Vega graphics (e.g. Athlon 200GE, Ryzen 3 2200G) may someday work too. But I'd rather wait for Intel Tiger Lake boards.

Looks like the file got corrupted somehow.

Try this one.

Can this patch be used in the 4.19 kernel?

You mean 4.9 in CE? It will probably not apply to 4.9, a new patch will be needed.

Edit: I updated my patch, please re-download

Did you update docker addon?

It is expected because I made some changes. Just create an empty .nocompat file in .update folder and it will update.

I believe they are called Panther Canyon NUCs with Tiger Lake SoC

In theory Tiger Lake should work with the current build. The cheapest Tiger Lake is Celeron 6305.

I'm not too interested in NUCs but when an ITX board with Celeron 6305 is available I will buy it.

Wi-Fi works fine here with RTL8821CU adapter.

^ you will have to manually adjust those for the current Kodi master.

Also you will have to revert CDRMObject: remove unused SupportsPropertyAndValue method · xbmc/xbmc@b29310d · GitHub or otherwise Kodi will not build.

The full patch that I used.

I fixed the url.

You mean how I merged? I made a patch from the below commits and applied it to current master. Required some tinkering as they don't apply cleanly anymore.
