Linux内核的可抢占性分析和研究

近年来,Linux在嵌入式方面的应用越来越广泛,改进Linux的性能,使其适用于实时领域成为一个极具潜力的发展方向。影响Linux实时性的主要因素之一是Linux内核的不可抢占性,因此对内核抢占性的研究迫在眉睫,对其进行分析和研究,详细阐述了抢占锁、互斥锁、中断处理、调度函数的实现原理并提出改进方案,最后测试修改后的内核并与原内核的数据进行了分析和比较。

Analysis and study of preemption of Linux kernel

The Linux application to the embedded aspect is extensive and the improvement of the Linux performance and application to the real-time character becomes an extremely potential development direction.One of the main factors affecting the Linux real-time character is that the Linux kernel is non-preemptive and the research on the Linux preemptive kernel character is looming.The realization principle about the preemptive lock,the mutex lock,the interruption handling,the scheduling function and the solutions to...
