[Qemu-devel] [Bug 1674925] Re: Qemu PPC64 kvm no display if --device virtio-gpu-pci is selected

[Thomas Huth]

When you use "-vga none" or "-nodefaults" with that kernel where you've
enabled xics, do you now get some output in the windows once Linux has
booted?

Title:
  Qemu PPC64 kvm no display if  --device virtio-gpu-pci is selected

Status in QEMU:
  New

Bug description:
  Hi,
  i did many tests on qemu 2.8 on my BE machines and i found an issue that i 
think was need to be reported

  Test Machines BE 970MP

  if i setup qemu with

  qemu-system-ppc64 -M 1024 --display sdl(or gtk),gl=on --device virtio-
  gpu-pci,virgl --enable-kvm and so and so

  result is doubled window one is vga other is virtio-gpu-pci without
  any start of the VM . pratically i dont have any output of openbios
  and on the virtual serial output

  the same issue i found is if i select:
  qemu-system-ppc64 -M 1024 --display gtk(or sdl) --device virtio-gpu-pci 
--enable-kvm and so and so

  
  i had been try to change all the -M types of all kind of pseries without any 
positive result.

  Ciao 
  Luigi
