[dpdk-dev] [RFC UPDATE PATCH 0/9] dmadev rfc suggested updates

[Bruce Richardson]

This patchset contains a series of changes to dmadev based on work being done to
port over our drivers to test this new infrastructure. Some of these are bug
fixes to enable compilation e.g. missing exports or meson.build files, while
others are suggested changes to enhance the API. All these patches are to be
applied on top of [1] as they are mostly suggested changes to that RFC i.e.
patches to the patch!

The final patch includes some basic sanity tests for copy operations that we
have ported over from the ioat self-tests to use the dmadev APIs. The basic
dataplane part of those tests is probably ok for now, but the initialization of
queues in that test code may need some enhancement. Feedback welcome.

A tree with all these patches applied can be got at [2] if anyone wants to use
that as a basis for working on drivers, or for other discussion.
