[dpdk-dev] [RFC 5/6] ring: introduce HTS ring mode

2020-02-24 Thread Konstantin Ananyev
Introduce head/tail sync mode for MT ring synchronization. In that mode enqueue/dequeue operation is fully serialized: only one thread at a time is allowed to perform given op. Suppose to reduce stall times in case when ring is used on overcommitted cpus (multiple active threads on the same cpu). A
