    Alder Lake GVT-d integrated graphics passthrough

    I happened to build another i9 12900k machine in that past month. I found the time over that past few days to run another Ubuntu setup on it. This time on bare metal. If you have a PCIE graphics card installed, the i915 drivers will not load. Took me a while to muster up the desire to crack...

    Alder Lake GVT-d integrated graphics passthrough

    Just checking to show the success I am having with this setup. I have restarted the server just a couple times since I set this up. I have intentionally tried to not restart it. The Plex server is now a solid 30 days of uptime. This server gets used daily by at least 2 users if not more...

    Man, there sure are a lot of variables to consider. I wonder if that kernel you used was causing interference? I have an Asus Z690-P motherboard.

    Alder Lake GVT-d integrated graphics passthrough

    I don’t blame you guys for doubting. When I had this setup originally it looked as though it was working, and then days later I would be upset by my server crashing. Look back at my posts in this thread, you can see the ups and downs I had. That being said, my server has yet to crash with this...

    Alder Lake GVT-d integrated graphics passthrough

    I just started 6 streams locally while some other users were already streaming. A few 4K HEVC transcoded down to 720p and 1080p and one 1080p h264 transcoded down to 720p. The remote streams were direct playing at the time. I let these play for 10-20 minutes and saw no issues. I also attached...

    If you can return the NUC, get your money back. I’ll do your stress test to see what’s going on from my end. Did you compile and install the three drivers I mentioned? They happen to relate to exactly what you think is wrong, VAAPI being one of them.

    Alder Lake GVT-d integrated graphics passthrough

    It looks like you have the i915 drivers enabled on your host with your kernel Cmdline arguments. The host cannot have these drivers enabled otherwise you will see issues. There are two grub configurations, one for your host, and one for your guest. Make sure you have them setup according to my...

    That’s great to hear. Let me know how the Plex transcoding works for you. Mine is still going great!

    Both of those setups are different than mine, one is a 13th gen raptor lake, and the other is using a bleeding edge kernel version (5.19xxx) No error messages on my VM, running sudo dmesg | grep HUNG yields no results. Also manually searching for any error message at all and only came across an...

    Alder Lake GVT-d integrated graphics passthrough

    It’s really not working for you. I just checked the uptime on my Plex server and it has been running for 18 days with the setup I described above and hardware transcoding has been functional. Whereas before my updates with hardware transcoding enabled, the server might run for 15 minutes...

    Alder Lake GVT-d integrated graphics passthrough

    The only special configuration options were passing through the correct PCIE device, OVMF Bios, Q35 machine type, and display none. Edit: Follow up, this virtual machine has been running without a reboot since I made the post about it working. It is very stable and hardware transcoding is...

    Alder Lake GVT-d integrated graphics passthrough

    Coming back to report the success I had last night. I let this sit in my bucket of "wait for developers to fix" for quite some time. Last night I mustered up the strength to want to try again. It seems as though I have got it to work. Proxmox Host Setup: I am not sure how much of this is...

    Alder Lake GVT-d integrated graphics passthrough

    Those threads paint a pretty grim picture. I can say with Linux I did get it working for small periods of time. Ultimately full iGPU passthrough was obtained, but I think the drivers or software utilization are just a little broke still. Time will tell.

    Alder Lake GVT-d integrated graphics passthrough

    Well, my LXC has been anything but reliable. When Plex starts transcoding with i915 it will eventually lead to a CPU hard LOCKUP, which ultimately takes the entire proxmox server down. I went back and tried testing this on the Proxmox host, and ended up with the same result. I have been...

    Hard LOCKUP i915 reset GuC -110

    Does IOMMU need to be enabled to have an LXC utilize the dev/dri device without seeing these errors pop up? I also have the E-cores disabled in my bios, could this be causing issues?
