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:
./seabios-rtx2080.sh 24
pid 2558's current affinity list: 0-23
pid 2558's new affinity list: 0-7
qemu4.0-system-x86_64: -device
vfio-pci,host=0a:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on,romfile=/media/dad/QEMU-SSD/qemu-wd/rtx.rom:
vfio 0000:0a:00.0: group 16 is not viable
Please ensure all devices within the iommu_group are bound to their vfio
bus driver.
pid 2558's current affinity list: 0-7
pid 2558's new affinity list: 0-23
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.
>lspci -nnk

i compile qemu 4:

this all worked great before
not sure how i got around the requirement to bind all devices in group
16 before.
here is my script:
#!/bin/bash
#DO NOT RUN THIS SCRIPT AS ROOT. IT FUCKS UP PULSEAUDIO!
cd /media/dad/QEMU-SSD/qemu-wd
export QEMU_AUDIO_DRV=pa
export QEMU_AUDIO_TIMER_PERIOD=200
export QEMU_PA_SERVER=/run/user/$ID/pulse/native
#MANUALLY RUN TASKSET AND QEMU AS ROOT HERE...
