In order to allow handling physical GPE in the guest, implement physical SCI interrupts forwarding from the host to the guest. It uses an eventfd based mechanism similar to how we normaly do forwarding of other level-triggered interrupts. The difference is that SCI trigger events from kernel are not injected directly to irqchip. In order to support injecting both physical and virtual SCI interrupts (so that some GPEs can be handled as physical while other GPEs can be emulated), SCI trigger event is intercepted by ACPIPMResource which injects it to irqchip via another eventfd - the same eventfd which is used for injecting virtual SCI interrupts. Similarly, resample event for physical forwarded SCI is received via the same eventfd as for virtual SCI, then forwarded back to kernel.

crosvm - The Chrome OS Virtual Machine Monitor
crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.
crosvm is currently used to run Linux/Android guests on Chrome OS devices.
