Module irqchip

Modules§

Apic
Interrupt: An interrupt to be sent to one or more Apics.
InterruptData: The vector and type of an Interrupt.
InterruptDestination: Specifies the destination processors for an Interrupt.
Ioapic
IrqEvent 🔒
IrqEventSource: Identification information about the source of an IrqEvent
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.
PendingInterrupts: Pending Apic interrupts to be injected into a vcpu.
Pic
Routes: A container for x86 IrqRoutes, grouped by GSI.
UserspaceIrqChip: An IrqChip with all interrupt devices emulated in userspace. UserspaceIrqChip works with any hypervisor, but only supports x86.

ApicBusMsg: A message from an Apic to the UserspaceIrqChip.
DestinationShorthand: A quick method of specifying all processors, all excluding self, or self as the destination.
DeviceId
IrqChipCap: A capability the IrqChip can possibly expose.
VcpuRunState: A capability the IrqChip can possibly expose.
