| 摘 要： | 基于控制中断执行时间的方法, 提出一种Linux 2.6内
核实时化改进方案, 解决了Linux实时任务在执行过程中可能被频繁中断干扰而产生响应时间过长的问题. 通过分析Linux 2.6内核的中断机制及打上Ingo Molar实时化补丁后的内核中断机制, 并根据与当前任务实时优先级的比较, 为中断安排恰当的执行时间规则, 实现任务的实时性响应. 实验结果表明, 改进方案的中断响应时间低于打上Ingo Molar实时化补丁后的内核中断响应时间.

| Abstract: | A real time improvement scheme of Linux 2.6 kernel is proposed on the basis of the method of controlling execution time of interrupt, this scheme can resolve the problem of long response time caused by frequent interrupts in the execution process of Linux real time tasks. By analyzing Linux 2.6 kernel interrupt mechanism as well as the interruption mechanism of the kernel branded Ingo Molar real time kernel patch, and arranging an appropriate execution time for interrupt by comparing with the current tasks real time priority, the task’s real time res
ponse was realized. Experimental results show that the interrupt response time of improvementscheme is shorter than that of the kernel with branded Ingo Molar real time kernel patch. |
