* The virtual PCI model delivers IRQs to the PIC by default and to the IOAPIC
|
|
* only if the guest operating system selected the IOAPIC with the '_PIC' ACPI
|
|
* method and if it called the '_PRT' ACPI method afterwards. When running a
|
|
* guest operating system which uses the IOAPIC, but does not call these ACPI
|
|
* methods (for example Genode/NOVA), IRQ delivery to the IOAPIC can be
|
|
* enforced with the 'force_ioapic' configuration option.
