| Thread-topic: | [PATCH] Enable the x2APIC enhancement to Xen |
On platforms which supports x2APIC, the patches enable this enhancement for Xen. The x2APIC specification is available at http://www.intel.com/products/processor/manuals/ http://download.intel.com/design/processor/specupdt/318148.pdf apicid_u8_2_u32.patch: changes the 'apicid' from u8 to u32; x2apic.patch: replaces the traditional MMIO-style interface to the MSR-style one; uses physical fixed mode to deliver interrupts to CPU0.
