Volatile has no ordering semantics. The rte_timer structure defines timer status as a volatile variable and uses the rte_r/wmb barrier to guarantee inter-thread visibility. This patch optimized the volatile operation with c11 atomic operations and one-way barrier to save the performance penalty. According to the timer_perf_autotest benchmarking results, this patch can uplift 10%~16% timer appending performance, 3%~20% timer resetting performance and 45% timer callbacks scheduling performance on aarch64 and no loss in performance for x86.
