I specifically spec’ced the server to include a AMD Radeon video card and an NVidia video card. Looking good! Blacklist drivers from loading perf/amd_iommu: Detected AMD IOMMU #0 (2 banks, 4 counters/bank).

AMD-Vi: IOMMU performance counters supported When rebooted (Make sure IOMMU is enabled in your BIOS) check to see if IOMMU is now active: dmesg | grep -e DMAR -e IOMMU After the command completes, do a reboot. To make sure the changes are taken into account after you reboot. It also parses a video command essential to making the first slot available for GPU passthrough.Īfter changing the line run a: upgrade-grub This changed the grub boot parameters to enable IOMMU for AMD in PT mode. Inside of /etc/default/grub change the following line to include: GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=pt amd_iommu=on video=efifb:off" The kernel I’m running at the time of writing is: Linux duhmedia 4.13.13-5-pve #1 SMP PVE 4.13.13-38 (Fri, 10:47:09 +0100) x86_64 GNU/Linux Change boot parameters Especially for AMD Ryzen, the newer kernel has certain patches which make virtualization and passthrough work a lot smoother and efficient then it did before! GPU passthrough tutorial/reference Testing repositoryĪt the time of writing it’s smart to enable the test repository within proxmox. This information below is gathered from a lot of helpful forum threads on the proxmox forum and all over the internet! Sadly there didn’t seem to be one place that lists everything so I’m going to give it a try.
#AMD APU DRIVERS PROXMOX HOW TO#
?īut how to configure this, sadly it’s not (yet) possible to just configure it from the GUI. With the GTX1050 doing the compositing in passthrough and using NVENC to do the encoding CPU usage drops to about 10% of 4 cores assigned and the GPU is utilized around 60% while sending 4K/60, a very big improvement and freeing up the CPU for other tasks.
#AMD APU DRIVERS PROXMOX WINDOWS#
I’ve tested with this in a Windows virtual machine before but without GPU assistance for compositing and stream decoding/encoding the amount of CPU power that this needs is insane (~80% of the Ryzen 1700x with 8 cores) to run 4K/30. I use either OBS or Xsplit to do my streaming but OBS is mostly the most efficient with given resources.
#AMD APU DRIVERS PROXMOX INSTALL#
You'll likely run into a couple of errors along the way, all of the errors I had were missing packages and the package I needed to install was buried in the last 10 lines of the error. It's for another patch, but steps are the same. No worries! I was struggling for quite a while too, planning on writing a blog post about all of that at some point to guide others through it, just haven't gotten around to it.
