Hi!
I see this in virtio_ring.c:
/* Put entry in available array (but don't update avail-idx *
until they do sync). */
Why is it done this way?
It seems that updating the index straight away would be simpler, while
this might allow the host to specilatively look up the buffer
The purpose of this email is to introduce the architecture and the design
principles. The overall project involves more than just changes to vmxnet3
driver and hence we though an overview email would be better. Once people agree
to the design in general we intend to provide the code changes to
Sure. We have been working on NPA for a while and have the code internally up
and running. Let me sync up internally on how and when we can provide the
vmxnet3 driver code so that people can look at it.

The VIRTIO_CONSOLE_RESIZE control message sent to us by the host now
contains the new {rows, cols} values for the console. This ensures each
console port gets its own size, and we don't depend on the config-space

This series adds resize support for multiple console ports. The size

Thanks, applied!
