| H A D | arm_gic_kvm.c | f6530926 Thu Oct 03 15:46:39 GMT 2019 Eric Auger <eric.auger@redhat.com> intc/arm_gic: Support IRQ injection for more than 256 vpus
Host kernels that expose the KVM_CAP_ARM_IRQ_LINE_LAYOUT_2 capability
allow injection of interrupts along with vcpu ids larger than 255.
Let's encode the vpcu id on 12 bits according to the upgraded KVM_IRQ_LINE
ABI when needed.
Given that we have two callsites that need to assemble
the value for kvm_set_irq(), a new helper routine, kvm_arm_set_irq
is introduced.
Without that patch qemu exits with "kvm_set_irq: Invalid argument"
message.
