[dpdk-dev] [PATCH 0/4] libeventdev API and northbound implementation

[Jerin Jacob]

As previously discussed in RFC v1 [1], RFC v2 [2], with changes
described in [3] (also pasted below), here is the first non-draft series
for this new API.

[1] http://dpdk.org/ml/archives/dev/2016-August/045181.html
[2] http://dpdk.org/ml/archives/dev/2016-October/048592.html
[3] http://dpdk.org/ml/archives/dev/2016-October/048196.html

Changes since RFC v2:

- Updated the documentation to define the need for this library[Jerin]
- Added RTE_EVENT_QUEUE_CFG_*_ONLY configuration parameters in
  struct rte_event_queue_conf to enable optimized sw implementation [Bruce]
- Introduced RTE_EVENT_OP* ops [Bruce]
- Added nb_event_queue_flows,nb_event_port_dequeue_depth, nb_event_port_enqueue_depth
  in rte_event_dev_configure() like ethdev and crypto library[Jerin]
- Removed rte_event_release() and replaced with RTE_EVENT_OP_RELEASE ops to
  reduce fast path APIs and it is redundant too[Jerin]
- In the view of better application portability, Removed pin_event
  from rte_event_enqueue as it is just hint and Intel/NXP can not support it[Jerin]
- Added rte_event_port_links_get()[Jerin]
- Added rte_event_dev_dump[Harry]

Notes:

- This patch set is check-patch clean with an exception that
02/04 has one WARNING:MACRO_WITH_FLOW_CONTROL
- Looking forward to getting additional maintainers for libeventdev


Possible next steps:
1) Review this patch set
2) Integrate Intel's SW driver[http://dpdk.org/dev/patchwork/patch/17049/]
3) Review proposed examples/eventdev_pipeline application[http://dpdk.org/dev/patchwork/patch/17053/]
4) Review proposed functional tests[http://dpdk.org/dev/patchwork/patch/17051/]
5) Cavium's HW based eventdev driver

I am planning to work on (3),(4) and (5)

TODO:
1) Example applications for pipelining, packet ingress order maintenance with
ORDERED type and ATOMIC synchronization services.
2) Create user guide


Jerin Jacob (4):
  eventdev: introduce event driven programming model
  eventdev: implement the northbound APIs
  event/skeleton: add skeleton eventdev driver
  app/test: unit test case for eventdev APIs
