The irq_type field has the following values:
- irq_type[0]:
- KVM_ARM_IRQ_TYPE_CPU:
out-of-kernel GIC: irq_id 0 is IRQ, irq_id 1 is FIQ
- irq_type[1]:
- KVM_ARM_IRQ_TYPE_SPI:
in-kernel GIC: SPI, irq_id between 32 and 1019 (incl.)
(the vcpu_index field is ignored)
- irq_type[2]:
- KVM_ARM_IRQ_TYPE_PPI:
in-kernel GIC: PPI, irq_id between 16 and 31 (incl.)
(The irq_id field thus corresponds nicely to the IRQ ID in the ARM GIC specs)
