Andre Przywara 2891a7dfb6 KVM: arm64: vgic-its: Implement MSI injection in ITS emulation ... When userland wants to inject an MSI into the guest, it uses the KVM_SIGNAL_MSI ioctl, which carries the doorbell address along with the payload and the device ID. With the help of the KVM IO bus framework we learn the corresponding ITS from the doorbell address. We then use our wrapper functions to iterate the linked lists and find the proper Interrupt Translation Table Entry (ITTE) and thus the corresponding struct vgic_irq to finally set the pending bit. We also provide the handler for the ITS "INT" command, which allows a guest to trigger an MSI via the ITS command queue. Since this one knows about the right ITS already, we directly call the MMIO handler function without using the kvm_io_bus framework.
