Summary KVM VFIO guest X hang with guest kernel > 4.15
Product DRI
Version XOrg git
Hardware x86-64 (AMD64)
OS Linux (All)
Status NEW
Severity normal
Priority medium

Hi

Host: Arch running kernel 4.20.3 / Qemu 3.1
Guest: Ubuntu 18.04.1 (tried Ubuntu 18.10 also) with any kernel after 4.15
Driver: Happens with current stable, git from Padoka PPA and amdgpu-pro 18.=
50

Issue: Vega 64 passed through to guest causes X to hang on boot using 100% =
CPU
for one of the passed through cores for the Xorg process. X never starts wi=
th
the stopping point being 'LoadModule: "dri2"'. I cannot see any r=
elevant errors
in Xorg.log or the KRB - though it's easily reproducible. The system is sti=
ll
alive and can be ssh'd into.

Adding the nomodeset kernel option allows the guest to boot to GUI (albeit
without acceleration).

Details: With Qemu 3.0 having more than ~12GB RAM assigned to the guest cau=
ses
this behaviour. With Qemu 3.1 the amount of RAM is irrelevant - the hang al=
ways
occurs.

Believe this is related to one of the GPU reset patches added to the 4.16
kernel as the guest boots fine with Qemu 3.0/3.1 and guest kernel 4.15 (tes=
ted
up to 16GB guest RAM).

1:

https://git.qemu.org/?p=3Dqemu.git;a=3Dcomm=
itdiff;h=3D3412d8ec9810b819f8b79e8e0c6b87217c876e32

Alternatively, setting the pci-hole64-size=3D0 can also avoid this issue:

 -global i440FX-pcihost.pci-hole64-size=3D0

or

 -global q35-host.pci-hole64-size=3D0

depending on your VM machine type.
