3.
4 kernel in supporting the real-time process with POSIX compliant real-time function,multithread,multitasks,preemptive kernel, O(1)scheduling algorithm,its real-time capability is very poor and can not ensure the response time of real-time task.
6内核源代码,特别对进程调度机制、中断机制、抢占式内核、定时器等几个主要方面做了深入的分析。
4) preemptive kernel
可抢占内核
5) preemptible kernel
可抢占式内核
1.
The preemptible method changes the kernel into preemptible kernel by modifying the interrupted handling and spinlock mechanism,while the low-latency method makes the kernel to execute other tasks by adding the scheduling point into long period tasks.
可抢占式内核利用改变中断的调度机制和自旋锁的运行方法使Linux的内核变成可抢占式的。
6) preemptive ability of linux kernel
内核抢占性能
1.
The low-latency scheme is adopted and preemption scheme to improve the preemptive ability of linux kernel,and one of the running queue in Linus system is modified by replacing with mulitiple running queues.
提出在快速自愈路由协议与试验系统中使用的嵌入式实时操作系统的设计方案是采用修改内核的方法,将低延迟方案与抢占方案结合共同提高Linux内核抢占性能,并对调度进行了改进,将原Linux系统中只有一个可运行队列的方式改为对每一个实时优先级给出一个可运行进程队列,每一个运行队列有一个标志,表明该队列是否为空,系统中还有一个变量,变量的值为当前可运行进程的最高优先级,进程调度时,取优先级最高的可运行队列。
