Hello,

I'm working for developing vdev of gpio for SS.

The interrupt feature of gpio is added in virtio v1.2.

For the host side, there is a gpio resource manager.
There is no code for interrupt in the gpio resource manager, like InterruptAttachEvent(), InterruptWait().
So, I added a thread with InterruptWait() in vdev code.

I wonder the interrupt handling in the vdev code is ok or not.
Can anyone also tell me this is ok or not.
If not, tell me better method please.
