This patch adds IRQ support for the virtio GPIO driver. Note that this uses the irq_bus_lock/unlock() callbacks, since those operations over virtio may sleep. Also the notifications for the eventq are processed using a work item to allow sleep-able operations.

Marc, Will it be possible for you to have a look at this patch, it will help us understand shortcomings of the specification better and this implementation as well. Thanks. -- viresh _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
