cybersteel8 Posted June 15, 2021 Share Posted June 15, 2021 Hi all, I am new to unraid and looking to build a new Plex server using the i5-11500 and using unraid on it. I found a video that stated that hardware acceleration wasn't supported by unraid during early April. I also found two threads, this one and also this one, that discussed some issues with this CPU and getting it to work properly in unraid. Could I get a confirmation that this CPU is now fully supported out-of-the-box without any kernel or boot tweaks to get the iGPU/quicksync features to work? Are those aforementioned issues resolved? Thanks in advance for your help. Quote Link to comment
SimonF Posted June 15, 2021 Share Posted June 15, 2021 Support is out of the box in 6.9.2 its just that 11th Gen support has to be enabled in the i915 driver included with the kernel level 6.9.2 supports. thats all the force probe entry is doing. just add force_probe=4c8a to you syslinux line. You may need to change the last 4 characters to match your GPU, lspci | grep VGA. Also install intel gpu top plugin. Quote Link to comment
cybersteel8 Posted June 15, 2021 Author Share Posted June 15, 2021 Thanks for your response Simon, that should be helpful for when I purchase the CPU. 36 minutes ago, SimonF said: lspci | grep VGA I ran this on my current Fedora computer and it gave results in a different structure. It looks like "0.02.0" for my VGA item in the lspci list. I am probably running an old kernel version, but will I see a different output when doing it in unraid? Quote Link to comment

I dont have a 11th Gen but my lspci 00:02.0 VGA compatible controller: Intel Corporation Device 9ba8 (rev 03) is my igpu. its the part in yellow you need. Quote Link to comment

Oh that's weird, mine looks different! 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06) This is for my Fedora machine, it's got an i5-4460 in it. I don't know why it says Xeon E3-1200 🤨 I am going to guess this will show differently when I pick up the new CPU. Let's assume it will be normal and what you suggested will work I'll post here in a week or so if it doesn't! Edited June 15, 2021 by cybersteel8 Quote Link to comment

Plugin intel-gpu-top now enables igpu on 11th gen so you just need to install when you get new cpu Quote Link to comment
eyeonly Posted July 31, 2021 Share Posted July 31, 2021 Hi everyone, I am planning to upgrade my current unraid server from i5 6500 to 11th or 10th generation. May i have an update on this topic? Can 11th Intel cpu, i5 11400 iGPU work well on unraid? QuiackSync is very imporant on my Plex Quote Link to comment

QuiackSync is very imporant on my Plex Hey mate, yeah, I got QuickSync to work perfectly fine with my i5-11500 I did need to install the intel_gpu_top app from the Community Applications plugin to get QuickSync to work. I also had to pass the /dev/dri directory to the Plex docker container as well. Check out the instructions regarding that docker path variable here: Quote Link to comment
arturovf Posted August 2, 2021 Share Posted August 2, 2021 No, support it's not perfect yet, 4k HDR to SDR tone mapping is not working well (green artifacts). Quote Link to comment

I am indeed having trouble with HDR to SDR tone mapping (the transcoder is failing completely), but QuickSync is indeed working when doing SDR content, both 4K and 1080p. The gpu driver is being forwarded to Plex and Plex's transcoder is indeed hardware accelerated. If you experience any problems with HDR transcoding, turn off HDR Tone Mapping in your Plex Settings > Transcoder section. Quote Link to comment

Well yes disabling HDR tone mapping is a workaround, but then you can't do several 4k to sdr transcodes because cpu can't cope it Quote Link to comment

Though, I think I need to point out that this is a Plex issue, not an Unraid one. This thread was started and bumped because of Unraid's support for this CPU. It supports it and hardware acceleration is available for Plex. Quote Link to comment
