Public bug reported:
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.

Paolo Bonzini commented on IRC: AMD avic requires kernel_irqchip=split.
Can you try using it? (released QEMU uses -machine
...,kernel_irqchip=split, git QEMU expects -accel kernel_irqchip=split).

Hi Philippe, thanks for replying.
The 'kernel_irqchip' parameter is a bit confusing to me. It looks like
the documentation was updated from it defaulted to 'off' as a -machine
parameter, to now it will default to 'on' as an -accel parameter.
This bug described how the value for 'default_kernel_irqchip_split'
parameter had been changed to 'true' in Q35 version 4.0, but then set
back to 'false' after discovering that it caused issues for Nvidia gpu
passthrough and other things:
https://bugs.launchpad.net/qemu/+bug/1826422
However, my problems with the AMD gpu passthrough are present when
switching between Q35 3.0 (which does work) and 3.1 (which does not
work), both of which would still have 'default_kernel_irqchip_split' set
to false.. so it does not seem to me to be related to 'kernel_irqchip'.
Q35 version 3.1 did introduce many other changes:
static void pc_q35_3_1_machine_options(MachineClass *m)
{
..
pcmc->do_not_add_smb_acpi = true;
m->smbus_no_migration_support = true;
m->alias = NULL;
pcmc->pvh_enabled = false;
..
GlobalProperty hw_compat_3_1[] = {
{ "pcie-root-port", "x-speed", "2_5" },
{ "pcie-root-port", "x-width", "1" },
..
I thought maybe those could cause the AMD Navi gpu problems, but I am
not that knowledgeable about these settings.
Also I do not have the AMD Navi gpu conveniently available anymore to
test.

Commit 11bc4a13 (Nov 13, 2019, merged after v4.2.0-rc5) moved the
kernel-irqchip parameter to -accel, but I think the default was
inadvertently changed to off. The documentation was changed to say the
default is on, but the code change seems to have done the opposite.
I found this when I tested my Windows Server 2016 VMs with the last qemu
from git. Windows boots and runs very slowly unless I add either
<ioapic driver='kvm'/> (kernel_irqchip=on) or <timer name="hypervclock"
present="yes"/> to the libvirt config. Using the qemu installed with
Ubuntu 19.10 (version 4.0.0), I can reproduce the slowness by explicitly
adding kernel_irqchip=off.
Details:
- Host CPU: Ryzen 3950X (16 core, 32 thread)
- Host RAM: 64 GiB
- Host OS: Ubuntu 19.10 64-bit, kernel version 5.5.0-rc4 (commit 738d2902773e + ACS override patch)
- Guest CPU: host-passthrough, 16 vcpus (8 cores, 2 threads, topoext).
- Guest RAM: 12 GiB
- Guest machine type: pc-i440fx-4.0 (BIOS boot)
- Guest OS: Windows Server 2016, build 1607

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.

Commit d1972be13f ("accel/kvm: Make "kernel_irqchip" default on") fixes
the default mixup I described above. This isn't related to Marshall's
issue as it involves qemu 3.0 vs 3.1, but at least it cleans up some
confusion.

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

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.
