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.
