What should have happened:
VM with GPU passthrough should start
What happend instead:
VM with GPU passthrough wouldn't start. I tried running 'lspci -nns
0000:10:00.0' but this hung the terminal. Virtual Machine Manager was
now showing it couldn't connect to the KVM daemon. I rebooted the Host
OS but running 'lspci -nns 0000:10:00.0' again hung and I still couldn't
start the VM with GPU passthrough.
Extra info:
After installing updates to the Host OS on 2025-4-10, VMs without GPU
passthrough worked fine. On 2025-4-12 I tried to start a VM with GPU
passthrough but it wouldn't start.
On 2025-4-10 one of the Host OS updates was linux-firmware:amd64
(20240318.git3b128b60-0ubuntu2.10 -> 20240318.git3b128b60-0ubuntu2.11).
I wanted to test downgrading the linux-firmware back to version 2.10 but
that is no longer available. I was able to find, from this launchpad,
the files that were in the 2.10 and 2.11 versions of linux-firmware. I
found the differences between the files for the amdgpu firmware files. I
overwrote the /lib/firmware/amdgpu files on my host OS with the files
from 2.10 and rebooted - the VM with GPU passthrough was able to start
(and the lspci command worked.)
The list of amdgpu firmware files I overwrote was:
gc_11_5_1_imu.bin.zst
gc_11_5_1_me.bin.zst
gc_11_5_1_mec.bin.zst
gc_11_5_1_mes1.bin.zst
