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

[luigiburdo]

Hi Thomas,

just exit like it is an error with a wrong option.
the output is only this   qemu-system-ppc64: KVM and IRQ_XICS capability must 
be present for in-kernel XICS
Same is if i add all the options i have the seme error.
look like qemu need for run in kvm  a  kernel with XICS option enabled and XICS 
 is present only from ibm power 5 to up if i remember good.
After work i can test it if needed on Qoriq e5500 too for check if there is the 
same issue on an emb ppc64 processor.

Ciao
Luigi

Does it exit, or just hang afterwards? Was this with or without --device
virtio-gpu-pci option? Do you get any output if you run QEMU with
"-nographic" instead?

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
