Plex for sure is behind (or doing weird stuff). Next to transcoding, HDR tonemapping does work for me in emby and jellyfin.

I do have the modprobe blacklist. I don't have force_probe in my boot config. Updated my post to reflect that.

I installed the kernel with these instructions Linked /dev/dri device to my docker plex container using the linuxserver variant (lscr.io/linuxserver/plex). I don't have force_probe=i195 in my boot config. I do have "blacklist i915" in /etc/modprobe.d/i915.conf I have intel_gpu_top installed. After that I enabled transcoding but left HDR tone mapping disabled.

Either I'm very lucky or I gotta disagree. Been running RC kernel for 2 weeks now. My server is never doing nothing. I'm constantly running encoding jobs in the background on 6 cores, other stuff running on the other 6, often transcoding on the GPU on foreground with 4 plex users. Hope I don't jinx it but it doesn't crash.

100% sure, CPU low, iGPU usage goes brrrrrrrrr 12400, combined with Gigabyte B660M DS3H if that matters. Running for 2 days now without problems and heavy use on 5.18 and 6.10.1. HDR tonemapping is still broken on plex (on emby it works), plex was working on it AFAIK. But HW resolution/quality transcoding works 100%.

Weird, I've been running on 6.10 with 5.18rc7 for some time now with 0 issues and heavy transcoding. I'll install 5.18 release today/tomorrow.

Now we wait for @thor2002ro to compile a new kernel

5.18 is now officially released!

Some further testing yes I think it works. It's just that Plex has a bug i think. On emby it fully works. Played 3 4k HDR to SDR transcodes and a background Plex optimize encode at the same time. No crash or anything. Why I think Plex is the problem now is that Plex is transcoding at 10-20 fps and needs burned in subtitles to have no artifacts. Emby is working perfectly while transcoding HDR to SDR at 160fps. Running on an 12400 btw.

Installed it, confirmed it's running with uname -r which shows 5.18.0-rc7-thor-Unraid HW HDR mapping (still) not (fully) working for me sadly. Still having artifacts. Except when I burn in PGS subs, then it works... Weird but true. But it's progress! Running latest plex and Unraid 6.10 (stable) Edit: actually also works if I force plex to burn in subtitles always.

Do I then need to remove "i915.force_probe=4680" from the boot configuration and remove the blacklist of the driver?

Wouldn't it work by installing a VM that is running ubuntu 22.04 with a 5.18 kernel? Run Plex in that VM, mount your appdata plex folder to the VM so you can easily switch back when it works in Unraid. Or am I missing something?
