Hi,

I'm developing a virtualised audio / DSP virtio and vhost driver pair 
and I'm currently somewhat stuck trying to figure out how to 
asynchronously notify the guest from the vhost driver. I'm using the 
vhost_add_used_and_signal() function to return data back to the guest 
in the guest context, when the guest initiated an operation, that's 
working well. But how do I "kick" the guest from an asynchronous, e.g. 
from an interrupt thread context?

Thanks
Guennadi
