> Subject: [PATCH v4 0/4] eventdev: add attribute based get APIs
> X-Mailer: git-send-email 2.7.4
> This patchset refactors the eventdev API to be more flexible
> and capable. In particular, the API is capable of returning an
> error value if an invalid device, port or attribute ID is passed
> in, which was not possible with the previous APIs.
> The implementation of this patchset is based on a v1 patch[1],
> and after some discussion this API was seen as the best solution.
> In terms of flexibility, the attribute id allows addition of new
> common eventdev layer attributes without breaking ABI or adding
> new functions. Note that these attributes are not data-path, and
> that PMDs should continue to use the xstats API for reporting any
> unique PMD statistics that are available.
> Regarding API/ABI compatibility, I have removed the functions from
> the .map files - please review the .map file changes for ABI issues
> carefully.
> The last patch of this series adds a started attribute to the device,
> allowing the application to query if a device is currently running.

> v4:
> - Rework based on review by Jerin
>   - default: cases into switches
>   - Remove old functions from .map file
>   - Remove /* out */ parameters
>   - Rework header file definitions to match logical order
> - Rework patch split
>   - Cleaner removal of queue_count() function

The changes looks good.

Since the functions are removed, we need to update .so version.
Please update LIBABIVER(file: lib/librte_eventdev/Makefile) and  update
the release notes
