[Qemu-devel] [PATCH 0/2] Disentagle ISA IRQs

[Avi Kivity]

Currently ISA IRQs are delivered directly to the PIC, which reroutes them
to the IOAPIC as well.  This patchset introduces ISA IRQs, which are routed
both to the PIC and the IOAPIC.  As a side effect, IOAPIC lines 16-23 are
enabled; it also becomes easier to add IOAPICs.

Avi Kivity (2):
  Route PC irqs to ISA bus instead of i8259 directly
  Route IOAPIC interrupts via ISA bus
