[Qemu-devel] [Bug 1488363] [NEW] qemu 2.4.0 hangs using vfio for pci passthrough of graphics card

[Peter Maloney]

Public bug reported:

2.3.0 (manjaro distro package) works fine. 2.4.0 (manjaro or the arch
vanilla one) hangs on the SeaBIOS screen when saying "Press F12 for boot
menu". All tested with the same hardware, OS, command and configuration.
It also starts without the GPU passed through, even with the USB passed
through. I am using the latest SeaBIOS 1.8.2.

The release notes say:
 VFIO
    Support for resetting AMD Bonaire and Hawaii GPUs
    Platform device passthrough support for Calxeda xgmac devices 
    
So maybe something there broke it.
    
I am using the arch qemu 2.4.0 PKGBUILD (modified to have make -j8 and removed iscsi, gluster, ceph, etc.), which uses vanilla sources and no patches. https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/qemu

I am not using a frontend. I am using a script I wrote that generates
the command below.

Guest OS here would be 64 bit windows 7, but it didn't start so that's
not relevant. Also a Manjaro Linux VM won't start.

CPU is AMD FX-8150; board is Gigabyte GA-990FXA-UD5 (990FX chipset).

full command line (without the \ after each line) is:

I ran a bisect, and here's the result:


b8eb5512fd8a115f164edbbe897cdf8884920ccb is the first bad commit
commit b8eb5512fd8a115f164edbbe897cdf8884920ccb

    target-i386: disable LINT0 after reset
    
    Due to old Seabios bug, QEMU reenable LINT0 after reset. This bug is long gone
    and therefore this hack is no longer needed.  Since it violates the
    specifications, it is removed.

Hi,

proxmox users report same bug here with qemu 2.4:

http://forum.proxmox.com/threads/23346-Proxmox-4b1-q35-machines-failing-to-reboot-problems-with-PCI-passthrough

we are going to test with reverting the commit to see if it's help.

      Platform device passthrough support for Calxeda xgmac devices 
      
  So maybe something there broke it.
      
  I am using the arch qemu 2.4.0 PKGBUILD (modified to have make -j8 and removed iscsi, gluster, ceph, etc.), which uses vanilla sources and no patches. https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/qemu

  I am not using a frontend. I am using a script I wrote that generates
  the command below.

  Guest OS here would be 64 bit windows 7, but it didn't start so that's
  not relevant. Also a Manjaro Linux VM won't start.

  CPU is AMD FX-8150; board is Gigabyte GA-990FXA-UD5 (990FX chipset).

  full command line (without the \ after each line) is:

  qemu-system-x86_64
      -enable-kvm
      -M q35
      -m 3584
      -cpu host
      -boot c
      -smp 7,sockets=1,cores=7,threads=1
      -vga none
      -device ioh3420,bus=pcie.0,addr=1c.0,port=1,chassis=1,id=root.1

      -device vfio-pci,host=00:16.2,bus=root.1
      -usb
      -device ahci,bus=pcie.0,id=ahci
      -drive file=/dev/data/vm1,id=disk1,format=raw,if=virtio,index=0,media=disk,discard=on
      -drive media=cdrom,id=cdrom,index=5,media=cdrom
      -netdev type=tap,id=net0,ifname=tap-vm1
      -device virtio-net-pci,netdev=net0,mac=00:01:02:03:04:05
      -monitor stdio
      -boot menu=on
