Dmytro Maluka ab50403924 acpi: event listener: ignore events for direct GPEs ... Ignore ACPI netlink events for GPEs which are configured as direct GPEs. Such GPEs are forwarded to the guest directly as physical GPEs using eventfd based forwarding of physical SCI interrupts (which ensures that the GPE handling in the guest is synchronized with SCI interrupt context in the host). Forwarding via netlink should be used for emulated GPEs only. With this change, we are still propagating all GPE events received by the host to the guest. In the future we may need to enhance this logic, since for some types of GPEs we may not want to inject them to the guest at all, e.g. for Thunderbolt hotplug GPE we want to receive it in crosvm and then inject a normal PCI hotplug interrupt instead.
