With the advent of GICv3 ITS in-kernel emulation, KVM GSI routing
appears to be requested. More specifically MSI routing is needed.
irqchip routing does not sound to be really useful on arm but usage of
MSI routing also mandates to integrate irqchip routing. The initial
implementation of irqfd on
On ARM, the MSI msg (address and data) comes along with
out-of-band device ID information. The device ID encodes the
device that writes the MSI msg. Let's convey the device id in
kvm_irq_routing_msi and use KVM_MSI_VALID_DEVID flag value in
kvm_irq_routing_entry to indicate the msi devid is
This patch adds compilation and link against irqchip.
On ARM, irqchip routing is not really useful since there is
a single irqchip. However main motivation behind using irqchip
code is to enable MSI routing code. With the support of in-kernel
GICv3 ITS emulation, it now seems to be a MUST HAVE
If the ITS modality is not available, let's simply support MSI
injection by transforming the MSI.data into an SPI ID.
This becomes possible to use KVM_SIGNAL_MSI ioctl and MSI
