[Qemu-devel] QXL VGA on ppc64?

[Qemu-devel] QXL VGA on ppc64?

[Michal Suchánek]

Hello,

I heard this configuration is not working very well.

However, just enabling QXL in configuration and spapr.c I get a kvm
emulation error.

So what issues does the configuration have and what is needed to enable
it?

I am interested in resizing guest display to match client screen size.

Thanks

Michal

spice is little endian for historical reasons.  There was (still is?)
ongoing work in both qxl emulation and spice code base to fix this, but
I don't think anyone went on testing and fixing things systematically on
bigendian machines.  You might want try asking on spice-devel though.

There also used to be some x86 dependency, but that was a small issue
compared to the byteordering and it got fixed while spice was enabled
for arm.

qxl + spice on ppc64le should do just fine, but only in case both host
and guest are le.

virtio-gpu is another option for that one.
