Module devices::irqchip::kvm::x86_64

Structs

• KvmKernelIrqChip
  IrqChip implementation where the entire IrqChip is emulated by KVM.
• KvmKernelIrqChipSnapshot 🔒
• 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.
• KvmSplitIrqChipSnapshot 🔒

Constants

• PIT_CHANNEL0_IRQ 🔒
  PIT tube 0 timer is connected to IRQ 0

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.
