[Xen-devel] IO_APIC in para-guest

["Dong, Eddie" <eddie.dong@xxxxxxxxx>]

Keir:
     When thinking more about IO_APIC virtualization in Itanium,
 I got a confuse: How is io_apic.c used in xenlinux (X86)?
      It looks like all the machine resource of io_apic is handled in 
xen (xen/arch/x86/irq.c), and the PIRQ based on event channel
 can be handled by pirq_type in linux/arch/xen/kernel/evtchn.c 
pretty well? Then what is the function of file io_apic.c? 
thx,eddie
