Subject: [PATCH] pit-in-hv.patch - Use ac_timer for PIT interrupt injection (more accurate time keeping) - Accelerate some critical PIT I/O operations in the hypervisor (saves 15us per op). Cuts down guest timer interrupt handler execution time by a third. - If the domain is scheduled out, make sure that interrupts are not lost - Add a generic framework for device I/O interception Signed-off-by: Edwin Zhai <edwin.zhai@intel.com> Signed-off-by: Arun Sharma <arun.sharma@intel.com> Signed-off-by: ian@xensource.com
