From 4925663a079c77d95d8685228ad6675fc5639c8e Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Wed, 4 Feb 2009 17:28:14 +0200 Subject: KVM: Report IRQ injection status to userspace. IRQ injection status is either -1 (if there was no CPU found that should except the interrupt because IRQ was masked or ioapic was misconfigured or ...) or >= 0 in that case the number indicates to how many CPUs interrupt was injected. If the value is 0 it means that the interrupt was coalesced and probably should be reinjected.
