The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.
If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.
Thank you and sorry for the inconvenience.
** Changed in: qemu
Status: New => Incomplete

Title:
pc-q35-4.1 and AMD Navi 5700/XT incompatible
Status in QEMU:
Incomplete
Bug description:
Hello,
I am not sure if this qualifies as a "bug"; it is be more of an
unknown issue with default settings. However, since the default value
of q35 default_kernel_irqchip_split was changed seemingly due to
similar user feedback, I thought this was important to share..
AMD Navi 5700/XT vfio-pci passthrough seems incompatible with
one/multiple settings in pc-q35-3.1 and higher. The workaround for me
is that pc-q35-3.0 still works fine passing through the GPU and
official drivers can load/install fine.
The default/generic GPU drivers in a Fedora 30 or Windows 1903 guest
do work; the monitor displays the desktop in a 800x600 resolution and
things are rendered fine.. so the basic functionality of the card
seems fine with pc-q35-4.1.
But attempting to use the official open source AMD driver with the
card resulted in a hung kernel for the Fedora 30 guest.. and a BSOD on
the Windows 1903 guest immediately during driver install.
I do not see any errors in Qemu command output.. did not investigate
other logs or KVM etc, because I am not sure what to look for or how
to go about it. Also not sure which combination of the latest q35
default settings are valid combinations to try either, because it
seems that multiple things have changed related to pcie-root-port
defaults and other machine options. I am happy to run tests and
provide feedback if that helps identify the issue.
I am using "Linux arch 5.4.0-rc6-mainline" kernel on ArchLinux host
with AMD Navi reset pci quirk patch applied.
My working Qemu command line is this:
