[Qemu-devel] [PATCH V2] Introduce a new bus "ICC" to connect APIC

2011-11-01 Thread pingfank

From: Liu Ping Fan 

Introduce a new structure CPUS as the controller of ICC (INTERRUPT
CONTROLLER COMMUNICATIONS), and new bus "ICC" to hold APIC,instead
of sysbus. So we can support APIC hot-plug feature.
