[PATCH v4 00/17] next-eventdev: event/sw software eventdev

[Harry van Haaren <harry.van.haaren@intel.com>]

The following patchset adds software eventdev implementation
to the next-eventdev tree.

Note that certain tests in this patchset require the queue overriding
patch to pass, but it is not a build-time dependency.

The main change is the reworked xstats_reset() API, which now includes
a "mode" to select the Device, Port or Queue to reset.

This implementation is based on the previous software eventdev
v3 patchset, now with comments addressed:

1) use NULL in test link() functions (Jerin)
2) add CONFIG_RTE_LIBRTE_PMD_SW_EVENTDEV_DEBUG=n to config/common_base (Jerin)
3) xstats_names_get() return values improved
4) Fix event/sw bug in re-configuration of ports
5) Rework QUEUE_CFG_DEFAULT overriding of queue type at eventdev layer
6) Improve port unlinking to use optimized pull_port() if possible
7) Fix leak of credits on re-configuration of the device after usage
8) Improved error handling of unsupported queue types
9) Allow more flexible re-configuration of ports (lb and single-link changes)
10) Handle reconfiguring of ordered queues multiple times without errors


Git log is clean, while checkpatch issues:
2 Errors on Complex Macro (which I beleive cannot be fixed)
4 Warnings in the scheduler logic, which reduce readability when fixed.
1 Else after return warning, which cannot be easily removed

This patchset contains the work of multiple developers,
please see signoffs on each patch.
