同时启动A和B,那么A和B进程是如何运行的?作者: topgun_007 时间: 2010-02-05 23:50
偶的理解:
对于实时进程,调度策略只是针对相同优先级的时候才会发挥作用。
如果有优先级高的实时进程,则总会执行它。
高优先级的所有实时进程都执行完成或者阻塞,低优先级的实时进程才有机会执行。作者: openspace 时间: 2010-02-08 21:58
《ULK3》
SCHED_FIFO
A First-In, First-Out real-time process. When the scheduler assigns the CPU to the process, it leaves the process descriptor in its current position in the runqueue list. If no other higher-priority real-time process is runnable, the process continues to use the CPU as long as it wishes, even if other real-time processes that have the same priority are runnable.
