Hi,

Anybody know anything about a fix for this problem? With the 3.50 bios version, passthrough is still not working, although I could found a video about a workaround to downgrade the bios, i don't want to take the risk to do that.]]> Sun, 17 Nov 2019 06:48:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=11471&PID=70094&title=bios-update-destroyed-my-kvm-vfio-setup#70094 https://forum.asrock.com/forum_posts.asp?TID=11471&PID=63925&title=bios-update-destroyed-my-kvm-vfio-setup#63925 Author: Kannen_g

Actually, scratch those last couple replies.

For some people that patch I posted fixes it entirely. For me, it gave me a working VM with some small issues. If you apply it, let me know how it works out for you and what your GPU is.]]> Sun, 19 May 2019 11:51:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=11471&PID=63116&title=bios-update-destroyed-my-kvm-vfio-setup#63116 https://forum.asrock.com/forum_posts.asp?TID=11471&PID=63115&title=bios-update-destroyed-my-kvm-vfio-setup#63115 Author: pantato

There is a "fix" that you can use to patch the linux kernel that sort of works. I can boot my VM now once per host boot on my rx580 after applying the patch.

https://clbin.com/GGnxm


Save that as a .patch file and look up how to compile the kernel with a patch for your respective distro. You must edit the 2nd to last 2 lines on the patch for your PCI-E ids.
eg. the "ls iommu" script given on the arch wiki (made a link here: http://ix.io/1Jqt ) shows my guest GPU PC id(s) like so:

IOMMU Group 16 24:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] [1002:67df] (rev e7)
IOMMU Group 16 24:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere HDMI Audio [Radeon RX 470/480 / 570/580/590] [1002:aaf0]

So I had to edit the patch to look like this:

[daniel@satori ~]$ cat build/linux/trunk/quirks.patch
diff --git a/drivers/pci/quirks.c b/drivers/pci/quirks.c
index e2a879e93d86..62b754253318 100644
