qemu/apic: minimal MSI/MSI-X implementation for PC
Implement MSI support in APIC. Note that MSI and MMIO APIC registersare at the same memory location, but actually not on the global bus: MSIis on PCI bus, APIC is connected directly to the CPU. We map them on the...
Handle init/sipi in a main cpu exec loop. (v2)
This should fix compilation problem in case of CONFIG_USER_ONLY.
Currently INIT/SIPI is handled in the context of CPU that sends IPI.This patch changes this to handle them like all other events in a maincpu exec loop. When KVM will gain thread per vcpu capability it will...
Remove io_index argument from cpu_register_io_memory()
The parameter is always zero except when registering the three internalio regions (ROM, unassigned, notdirty). Remove the parameter to reducethe API's power, thus facilitating future change.

Don't use cpu_index as apic_id.
(patch is on top of "Apic creation should not depend on pci" series)
Currently cpu_index is used as cpu apic id on x86. This is incorrectsince apic ids not have to be continuous (they can also encode cpuhierarchy information). This patch uses cpuid_apic_id for initial apic id...
Introduce reset notifier order
