[win-pv-devel] [PATCH 00/10] Add multi-queue support

[Owen Smith <owen.smith@xxxxxxxxxx>]

This patch series implements multi-queue support.
A queue will be created per vCPU, and up to min(vCPUs, 
"multi-queue-max-queues") queues
will be used by default. If "multi-queue-max-queues" is not present, only 1 
queue is used
which has the same behaviour as the previous protocol.
Note: without patches to xennet, the packet steering algorithm will deliver all 
packets to 
  queue 0

1: Add a new transmitter packet to the vif interface header and use this 
structure
   internally.
2: Bump the vif interface version to 2, add new calls and macros to access the 
extended
    interface methods.
3-9: Implement multi-queue behaviour, steering packets based on a supplied hash 
value
10: Reduce event channel usage by not creating event channels that would be 
unused

Owen Smith (10):
  Rework transmitter packet code to use an internal cache of objects
  Add VIF interface version 2
  Store maximum number of queues allowed
  Create a transmitter/receiver ring per max-queue
  Split notifier into a list of queues.
  Dont call through to inactive queues
  Write queue values under <frontend>/queue-<id> and "multi-queue-num-queues"
  Steer transmitter packets to queues
  Pin queue's DPC to appropriate vCPU when using multiple queues
  Only call EVTCHN:Open for rx and tx or single event channel, based on 
       "feature-split-event-channels"
