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. -Harry [1] http://dpdk.org/dev/patchwork/patch/27152/ --- v3: - Fix checkpatch issues... somehow I broke my checkpatch script :/ v2: - New APIs design based on discussion of initial patch.
