Hi,
now i understand . xics have to be build in kernel and is needed by qemu 2.9
with kvm.
if is not present in the kernel have the issue that i been reported about xics.
I make a test on ubuntu 16.10 and on 17.04. the two distro are ppc 32 and
generic.
i had build the stable kernel 4.10.5 two times with the same config the only
parameter that i had change was the xics one was yes and the other was no.
On the two ubuntu version when i run kernel without xics i had the issue
reported. if i run the kernel with xics enabled qemu 2.9 is working and was
gave no issue.
but ...
on Fedora server 25 ppc64 if xics is present in the kernel the system (fedora)
not run and freeze after the kernel bootstrap.
Hope all is understandable
Thanks
Luigi

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
