This patchset adds support for event mode in l3fwd.
The poll mode is still the default mode of operation.
The following new command line parameters are added:
--mode: Dictates the mode of operation either poll or event. If unset then
by default poll mode is used.
--eventq_sched: Dictates event synchronization mode i.e. either ordered,
atomic or parallel.
--event-eth-rxqs: Number of ethernet RX queues per device.
Based on event device capability the configuration is done as follows:
- A single event device is enabled.
- The number of event ports is equal to the number of worker
cores enabled in the core mask. Additional event ports might
be configured based on Rx/Tx adapter capability.
- The number of event queues is equal to the number of ethernet
ports. If Tx adapter doesn't have internal port capability then
an additional single link event queue is used to enqueue events
to Tx adapter.
- Each event port is linked to all existing event queues.
- Dedicated Rx/Tx adapters for each Ethernet port.
v4 Changes:
----------
- Update documentation about --event-eth-rxqs. (Jerin)
- Add validation for command line options that are specific to event/poll mode.
- Fix event device service initialization.
v3 Changes:
----------
- Unify argument parsing.
- Segregate poll mode and event mode initialization.
- Simplify event resource creation and accesses.
- Integrate http://patches.dpdk.org/project/dpdk/list/?series=8002 series.
- Reduce code duplication in lpm.
v2 Changes:
----------
- Shorten the structure name `s/event_rsrc/evt_rsrc` `s/l2fwd_rsrc/rsrc`.
- Use rte_panic instead of rte_exit.
- Rebase on top of Tx adapter change http://patches.dpdk.org/patch/60971.
- Add parallel mode support.
- Fix missing eventdev args parsing.
