Module x86_64

Structs

KvmKernelIrqChip

IrqChip implementation where the entire IrqChip is emulated by KVM.

KvmSplitIrqChip

The KvmSplitIrqsChip supports KVM’s SPLIT_IRQCHIP feature, where the PIC and IOAPIC are emulated in userspace, while the local APICs are emulated in the kernel. The SPLIT_IRQCHIP feature only supports x86/x86_64 so we only define this IrqChip in crosvm for x86/x86_64.

Functions

kvm_default_irq_routing_table 🔒

Default x86 routing table. Pins 0-7 go to primary pic and ioapic, pins 8-15 go to secondary pic and ioapic, and pins 16-23 go only to the ioapic.

kvm_dummy_msi_routes 🔒

routes_conflict 🔒

Convenience function for determining whether or not two irq routes conflict. Returns true if they conflict.
