[Qemu-devel] [PATCH v3 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 v3:
 - Rebased over recent upstream master
 - Aligned license of hw/kvm/i8254.c to the other PIT files

The patches apply on top of upstream commit 88e6c60671, thus require an
uq/master update.

Please merge.

Jan Kiszka (4):
  i8254: Factor out base class for KVM reuse
  i8254: Open-code timer restore
  kvm: Add kvm_has_pit_state2 helper
  kvm: x86: Add user space part for in-kernel i8254
