[PATCH] vhost: Add polling mode
...), all of which hurts performance.
If the system is under-utilized (has cpu time to spare), vhost can continuously
poll the virtqueues for new buffers, and avoid asking the guest to kick us.
This patch adds an optional polling mode to vhost, that can be enabled via a
kernel module parameter, "poll_start_rate".
When polling is active for a virtqueue, the guest is asked to disable
notification (kicks), and the worker thread continuously checks for new buffers.
When it does discover new buffers, it simulates a "kick" by invoking the
underlying backend driver (such as vhost-net), which thin...
