Re: [Qemu-devel] Virtio Polling Mode

[Anthony Liguori]

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 for your time!

Best Wishes,
