[win-pv-devel] [RFC PATCH 0/6] Multi-queue frontend

[owensm <owen.smith@xxxxxxxxxx>]

Experimental implementation of the multi-queue protocol.
This allows frontends to use multiple queues/rings when
used with a compatible backend (xen-blkback). blkif_request_t's
are directed to a particular queue based on the calling CPU, which
is unlikely to sufficiently balance any load. No performance testing
has been done yet - this RFC is for comments on the overall implementation
strategy.

owensm (6):
  Update blkif.h
  Rename XENVBD_RING -> XENVBD_PROTOCOL
  Query for "multi-queue-max-queues"
  Add initial multi-queue support
  Increase concurrent calls to StartIo
  Fix up more than 1 queue
