[PATCH 0/6] whpx: i386: some fixes

Posted by Mohamed Mediouni 1 week, 6 days ago

Some (backportable) fixes for x86_64 whpx.

-cpu host on Intel CPUs works again without needing a -cpu host,vmx=off
workaround.

A floating point state sync fix and re-injecting exceptions on debug outside
of the int1 case.

I'm picking this patch set for qemu 11.1.x stable series.
