Hi Anthony,
Thanks for your reply!
What I am looking for is that whether there is one mechanism that when
virtio-blk host side finished the requests. Instead of using irq to notify
the guest. Is there any other method to notify the guest (guest_notifer)?
Thanks for your time!
Best Wishes,

Hi Jason,
Thanks for your reply! I am more concerned with polling mode about
virtio-blk right now. Later I will focus on polling mode on virtio-net.
I don't know whether the polling mode is already existed for virtio-blk or
we should implement it by ourselves if we need this feature.
Thanks for you

Hi Yaohui,
Yes, there is a flag associated both with the used and the avail rings to
disable notifications. This can be used to implement polling.
There have been multiple research projects/papers that have experimented
with polling.

Hi All,
I am wondering whether virtio has provided polling mode already. Instead of
sending a event from guest to host through eventfd on guest side and inject
an interrupt into guest on host side to notify each other? Could both sides
keep polling the Vring to communicate with each other?
Thanks f
