Thread-topic: [Xen-devel] [PATCH]HVM acpi timer update
The patch updated the hvm acpi timer by reducing invocations to
timer_update and some minor code style clean up:
1) Fixed new qemu 0.8.1 pm timer incorrect frequency and allow acpi
windows install and boot correctly
2) Resolved performance issues caused by old acpi timer, testing showing
guest IDE DMA and kernel build have the same performance on non-acpi
