Likewise, Plex on Ubuntu now has working HW transcoding. The problem is Kernel + Specific ICR version. Unraid will crash on Alder Lake if you enable the GPU even WITHOUT actually hardware transcoding. Ok help me understand how the GPU is enabled without actually hardware transcoding. Is there a way to have unRaid just totally ignore the GPU? Quote Link to comment

If you just run Unraid out of the box on 12th gen, and don't do anything with the iGPU then there's no problem at all an 12th gen works very well. Well, I don't know if the current governer works correctly with P/E cores, as I've got a 12400 (only P cores), but it's stable regardless. Quote Link to comment

In my old system I had a cheap NVidia card that seemed to work for some transcoding, but until now I've mostly only downloaded 720p shows. That's mostly because I share Plex (with just one other person), and that was easier to transcode 🙂 I need help to understand exactly what people are doing: Can Plex, running on UnRaid 6.10.3, use the iGPU on the 12th gen chips at all? I saw something about only when using HDR, but I have no idea if that's correct, or how to enable/disable HDR. Are the 11th gen chips in the same boat? Is this problem only with 4K shows? I'm messing around with those now, but I'm not sure if this problem affects every video format or just some. Is anyone is using the iGPU on a 12th gen chip at all, is it documented anywhere how they were able to do that? I've read there are kernel changes that will fix this (?), but I'm still not sure if that is an UnRaid change or a Plex change? Sorry, I am just completely lost. Thanks for your help!

Absolutely this - also, can confirm it was 10th gen, with the intro of Xe graphics for their integrated GPU's. Intel had already laid the groundwork to support Xe with the open source community (including working with ffmpeg) prior to release to help ensure a "smooth" release. Plex's tweaks to it were out of tree and significantly behind current though, so they received none of those fixes/enhancements. I assume it has to do with their attempts to lock down transcoding to paid plex pass holders. Same issue with their SQLite implementation - they've hacked the hell out of it such that it's basically unsupportable by anyone but them... which means if it goes paws up, you're SOL when it comes to many manual DB repair options. I hate that plex has become the defacto media streaming tool given all this, and wish I could convince enough of my users to move away from it that I could stop supporting it 😓 1 Quote Link to comment

It doesn't matter though Jellyfin or Emby won't hardware transcode under Unraid either until the kernel is updated. Personally, I've got a Jellyfin instance running as well on a separate PC (also running Plex) and really? I think Plex is just better. Much more feature rich. But to each their own. 1 1 Quote Link to comment
Waffleophagus Posted July 19, 2022 Share Posted July 19, 2022 Hey at the risk of derailing the conversation a bit, has anyone attempted to do tests to see how well the Windows 11 scheduler deals with passing in a mixture of both P and E cores? How well it handles it? I know that a lot of folks just pass through all the P cores for gaming and what not, but I would love to see more data to see how/if kvm has gotten better at allocating the different cores to the host OS's scheduler. Thanks! Quote Link to comment

Thanks! The last time I tried it was about a month and a half ago, and at least at that time, it was all sorts of borked. The QEMU folks are working on it though - the first kernel with support built in was 5.18, so it's not even fully supported by the hypervisor yet (6.10.3 is still 5.15; 5.18 still seems to have some 'teething' issues last I'd heard). And just to be clear, by 'fully supported', I'm referring to the various alder lake specific components (IPI/thread director/et al) - doesn't mean it 'won't work', just that it 'won't function explicitly as designed'. 1 Quote Link to comment

Kthwaits Posted July 25, 2022 Share Posted July 25, 2022 Does anyone have Unraid running with an Alder Lake CPU and a W680 chipset motherboard (such as the Supermicro MBD-X13SAE)? I'm currently using a Z690 board but I specifically went with an Alder Lake i9 because at the time they had just announced that it would also be supported on W680 boards once they were available. The idea being that I would have the ability to upgrade my MB and ram to DDR5 ECC (which W680 enables for Alder Lake i5, i7, & i9s) later on. As of now there are still only a couple W680 boards available but I'm curious if anyone has tried one with Unraid yet and what their experience has been. Quote Link to comment
Waffleophagus Posted July 25, 2022 Share Posted July 25, 2022 Thank you all for the feedback, ended up going with AMD for this build. Hope you guys have the best of luck with Alder Lake! Quote Link to comment
snazz Posted July 26, 2022 Share Posted July 26, 2022 (edited) Saw 6.11.0-rc1 was out early this morning. HDR Tone Mapping still hangs trying to start playback. Disabling that but leaving HW transcoding enabled allows playback. Too early to comment about stability. Edit: Just tried this from the plex docker's console: apt-get install ocl-icd-libopencl1 beignet-opencl-icd ...and got: beignet-opencl-icd is already the newest version (1.3.2-7build1). ocl-icd-libopencl1 is already the newest version (2.2.11-1ubuntu1).

xlucero1 Posted July 26, 2022 Share Posted July 26, 2022 Great to hear @snazz, keep us updated please [btw I have a very similar build as you do!] I am hoping someone can help post a guide to building a VM on this Alderlake. I am having a very tough time with simultaneous hardware and OS transition from 6.8.3 thank you all very much. Quote Link to comment

I don't pretend to fully understand the issue, but ChuckPA (the Community Manager at Plex) has been working with folks to get HW transcoding working in Ubuntu over here: https://forums.plex.tv/t/pms-packaging-07-2022-update-forum-preview-testing/799912 I assume it will eventually filter down to Docker/Unraid.

dchamb Posted July 26, 2022 Share Posted July 26, 2022 It's getting really confusing. I have an Alder Lake system with an Asus 690 m/b ready to go for transitioning from my very old Ivy Lake system. I run primarily Plex but without HW transcoding. Would you make the switch if you were me? Quote Link to comment

Would you make the switch if you were me? Yeah, I get how it's confusing. I don't fully understand all this ICR stuff. Bottom line is that it's being worked on and it will eventually work. As far as your situation is concerned...if you still won't need HW transcoding after migrating to Alder Lake, then I'd say go for it. It will work fine without HW transcoding and would be a huge step up in performance from your Ivy Lake system. Quote Link to comment
