[ovs-dev] [PATCH 0/4] ovn-controller: Separate thread for pinctrl

[Han Zhou]

This patch series is the first attempt of ovn-controller multi-threading.
The intention is to avoid flow re-computing being triggered by unrelated
input. An obvious example is that packet-in message from vswitchd to
ovn-controller will trigger full round of flow computing before processing
the actual packet-in message, such as DHCP request. This becomes a
serious problem in large scale environment where each ovn-controller
has large amount of flows to compute and install. It will be even worse
considering in the future we use ovn-controller packet-in for packet
logging.

An alternative approach has been tried but didn't go well, which was
discussed in the link below:

Han Zhou (4):
  ovn-controller: decouple localnet_port update from patch_run
  ovn-controller: readonly mode binding_run and get_br_int
  ovn-controller: refactor and abstract ovs_idl registering
  ovn-controller: Use separate thread for packet-in processing.
