[Qemu-devel] [PATCH 0/4] uq/master: Introduce KVM PIT support

[Jan Kiszka]

This adds another piece of qemu-kvm to upstream: The accelerated
in-kernel model of the i8254. It does this in the same fashion as the
interrupt controllers were already introduced. And it even has one bug
less than qemu-kvm: PC speaker output still works with KVM acceleration
enabled.

Changes in v2:
 - Rebased over recent upstream master to reflect QOM changes

The patches depend on the follow upstream or uq/master patches:
 - pit, hpet, pcspk: fixes & preparation for KVM (v4, 7 patches)
   http://thread.gmane.org/gmane.comp.emulators.kvm.devel/86006
 - kvm: Implement kvm_irqchip_in_kernel
   http://thread.gmane.org/gmane.comp.emulators.qemu/134399
 - KVM: Fix breakages of QOM conversion
   http://permalink.gmane.org/gmane.comp.emulators.qemu/134844

It is based on upstream commit cb437e48ab (before the VGA breakage). The
series plus dependencies is also available at

    git://git.kiszka.org/qemu-kvm.git queues/kvm-pit

Please review / merge.
