[PATCH V2 2/2] kvm tools: Make virtio-pci's ioeventfd__add_event() fall back gracefully if ioeventfds unavailable

2011-12-12 Thread Matt Evans
Some KVM implementations (e.g. PPC) don't yet support ioeventfds, so don't bomb out/die. virtio-pci is able to function if it instead uses normal IO port notification. Signed-off-by: Matt Evans m...@ozlabs.org --- tools/kvm/Makefile|2 +- tools/kvm/include/kvm/ioeventfd.h |
