[Xen-devel] How dispatch a vIRQ to all guests in ARM

[Josh Zhao <joshsystem@xxxxxxxxx>]

Hi,

I am reading the code, but I can't understand how an interrupt dispatch to all guests?  As code description that do_IRQ() -->vgic_vcpu_inject_irq(), but it seems only inject an irq into ONE VCPU. Is there a case that one irq registered by many guests?

Thanks,

josh zhao
