Hi, this series teaches kvmtool how to support KVM's ITS emulation. Also (as this is somewhat related and has been co-developed) it enables GSI routing for ARM/ARM64, which allows IRQFDs to be used, for instance to use vhost_net. At the moment this is dependent on the guest using the ITS emulation, but GICv2M support patches will follow. The first 4 patches are generic fixes and refactoring to pave the road for the rest of the patches. Most importantly the first two pull the GSI routing code from x86 into generic code. The following 7 patches add ITS emulation support. They reserve and register the required ITS register frame and populate a DT node with the necessary data. Also the patches add the device ID to the KVM_SIGNAL_MSI ioctl. For enabling a guest ITS, the new --irqchip= parameter is extended to allow "--irqchip=gicv3-its". The remaining three patches enable IRQ GSI routing for ARM/ARM64. This is needed to use IRQFDs, which is a prerequisite for vhost functionality, for instance. The code sets up the (dummy) SPI routing table and adds the device ID to the routing entry. The ITS part relies on my kernel ITS emulation patches [1], the IRQ routing part on Eric's respective series[2]. This code can also be found in my kvmtool git repository [3]. Cheers, Andre.
