摘要 标准Linux内核是不能被抢占的,致使调度延迟较大,这是导致Linux系统实时性不强的主要原因,对Linux内核不可抢占性进行了深入分析,阐述了两种降低调度延迟的方案：低延迟方案和内核抢占式方案,并对这两种方案进行了测试与分析。 Standard Linux kernel is non - preemptive, which leads to long latency and poor real - timeness of Linux. The non - preemption was analyzed, and two schemes of reducing scheduler latency were described： LOW Latency Patch and Preemption Patch. Finally the results were presented.
