driverctl worked.
my new friend in the linux world.
however, if you have linux mint 19 or ubuntu 18.04 you will need to
compile a copy.
here is how:
|sudo apt-get install debhelper pkg-config dpkg-dev cd ~/Downloads wget
http://archive.ubuntu.com/ubuntu/pool/universe/d/driverctl/driverctl_0.111.orig.tar.gz
tar -xf driverctl_0.111.orig.tar.gz cd driverctl-0.111/ wget
http://archive.ubuntu.com/ubuntu/pool/universe/d/driverctl/driverctl_0.111-1.debian.tar.xz
tar -xf driverctl_0.111-1.debian.tar.xz rm
driverctl_0.111-1.debian.tar.xz dpkg-buildpackage -uc -us sudo apt-get
install ../driverctl_0.111-1_all.deb |
examples:
driverctl list-devices ; see a list of all device ids on your system and
which driver is in use
driverctl set-override 0000:0b:00.3 vfio-pci; override the device to
load vfio-pci instead
works like a charm. took over the two stubborn devices in my video card
to force them to use vfio-pci and now the virtual machine boots once again.

Thanks.
I tried grabbing them using pci-stub.
Didnt work.
Still not bound.
I will look into driverctl.

Hello,
I recently had to reinstall my OS, but kept all my personal files.
One of the things that needs to be resetup partially is qemu.
I am getting the following error when running my qemu4.0 script to
start
win10:

Please ensure all devices within the iommu_group are bound to their
vfio
bus driver.

I had this before but cant remember how i Resolved it.
Here is my iommu group 16:
for a in /sys/kernel/iommu_groups/*; do find $a -type l; done
/sys/kernel/iommu_groups/16/devices/0000:0a:00.2
/sys/kernel/iommu_groups/16/devices/0000:0a:00.0
/sys/kernel/iommu_groups/16/devices/0000:0a:00.3
/sys/kernel/iommu_groups/16/devices/0000:0a:00.1
group 16 is my evga rtx 2080 video card
it has 4 devices. video, audio, usb, and serial bus.
here is my cmdline:
cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-5.0.0-32-generic root=/dev/mapper/vg-root ro
vfio-pci.ids=10de:1e04,10de:10f7 mitigations=off
i only hold the video and audio as the usb and serial wont hold.

Ultimately all these devices need to be bound to vfio-pci or unused
ones can be bound to pci-stub, default host kernel drivers are not an
option. Have you tried driverctl as a means to bind them to vfio-pci?
The pci-stub driver is usually built statically into the kernel
allowing it to claim devices before modules, ie.
pci-stub.ids=10de:1ad6,10de:1ad7. The only way you could have
previously left them bound to default host drivers would have been
forcing group separation with the ACS override patch (not recommended).
Thanks,
Alex
