linux 实时调度策略 修改及测试
关于linux中的实时调度策略，主要包括FIFO两种，在文章http://4989715.blog.51cto.com/4979715/1416852中有介绍。RR实时调度策略针对优先级相同的实时进程，采用了平分时间片的做法，这对于需要赋予不同权重的进程而言是不足的，本文对linux3.5.4的内核代码做出修改，使得同一优先级的进程可以根据其不同的重要性分配权重，称为WRR调度策略，内核源码稍后上传，下面给出改进后的测试用例及测试结果。
1、测试环境

RR测试结果：
2、输出结果分析
在对输出结果分析之前，首先对输出结果中格式进行说明：
a：输出结果各列参数及其含义分别为：
time_off： 标志
t-time_offset：当前时间
prev_task_name:将要唤出的进程名称
prev_pid：将要唤出的进程号
prev_priotiry: 将要唤出的进程优先级
prev_state：将要唤出的进程状态
next_task_name：将要唤入的进程名称
next_pid：将要唤入的进程id
next_priority：将要唤入的进程优先级
next_state:将要唤入的进程状态
b:关于优先级的说明：
/kernel/sched/core.c prio = MAX_RT_PRIO-1 - p->rt_priority |
/include/linux/sched.h #define MAX_USER_RT_PRIO100 #define MAX_RT_PRIOMAX_USER_RT_PRIO |
所以t1.c，t2.c中设置的70的优先级，是指实时优先级，对应的内核态优先级为29
c：关于进程状态的说明：
/include/linux/sched.h ...... #define TASK_RUNNING0 #define TASK_INTERRUPTIBLE1 #define TASK_UNINTERRUPTIBLE2 #define __TASK_STOPPED4 #define __TASK_TRACED8 ...... |
分析结果一：
...... time_off ( 4458784) t1( 4073)(prio= 29)(state= 0)---> t2( 4072)(prio= 29)(state=0) time_off ( 4558785) t2( 4072)(prio= 29)(state= 0)---> t1( 4073)(prio= 29)(state=0) //通过分析上面两行得出t2的调度时间片为：4558785-4458784；约为100ms time_off ( 5058785) t1( 4073)(prio= 29)(state= 0)---> t2( 4072)(prio= 29)(state=0) time_off ( 5158784) t2( 4072)(prio= 29)(state= 0)---> t1( 4073)(prio= 29)(state=0) time_off ( 5658784) t1( 4073)(prio= 29)(state= 0)---> t2( 4072)(prio= 29)(state=0) //通过上面两行得出t1的调度时间片为：5658784-5185784；约为500ms ...... |
分析结果二：
//t1 进程开始时间 time_off ( 2059788) t1( 4073)(prio= 29)(state= 0)---> t2( 4072)(prio= 29)(state=0) //t1进程结束时间 time_off (23260904) t1( 4073)(prio= 29)(state= 64)---> t2( 4072)(prio= 29)(state=0) //t2进程开始时间 time_off ( 1961523) t2( 4072)(prio= 29)(state= 0)---> ms( 4073)(prio= 19)(state=0) //t2进程结束时间 time_off (37347534) t2( 4072)(prio= 29)(state= 64)---> kworker/0:2( 2384)(prio= 120)(state=0) |
从分析结果二中可以看出：
t1进程的执行周期约为：21s
t2进程的执行周期约为：36s
从而可以看出：通过修改权重，可以使得进程的执行周期明显缩短。
分析结果三:
...... time_off ( 8946304) t2( 4729)(prio= 29)(state= 0)---> t1( 4730)(prio= 29)(state=0) time_off ( 9046304) t1( 4730)(prio= 29)(state= 0)---> t2( 4729)(prio= 29)(state=0) //通过分析上面两行得出t2的调度时间为：100ms time_off ( 9146304) t2( 4729)(prio= 29)(state= 0)---> t1( 4730)(prio= 29)(state=0) time_off ( 9246304) t1( 4730)(prio= 29)(state= 0)---> t2( 4729)(prio= 29)(state=0) //通过分析上面两行得出t1的调度时间为：100ms time_off ( 9346306) t2( 4729)(prio= 29)(state= 0)---> t1( 4730)(prio= 29)(state=0) ...... |
分析结果四
//t2进程开始时间 time_off ( 8148181) t2( 4729)(prio= 29)(state= 0)---> ms( 4730)(prio= 19)(state=0) //t1进程开始时间 time_off ( 8247305) t1( 4730)(prio= 29)(state= 0)---> t2( 4729)(prio= 29)(state=0) //t2进程结束时间 time_off (42932701) t2( 4729)(prio= 29)(state= 64)---> t1( 4730)(prio= 29)(state=0) //t1进程结束时间 time_off (43125598) t1( 4730)(prio= 29)(state= 64)---> kworker/0:0( 2750)(prio= 120)(state=0) |
从分析结果二中可以看出：
t1进程的执行周期约为： 34s
t2进程的执行周期约为： 35s
从而可以看出：两个进程的执行周期大致相同
最终结论：
采用WRR调度策略，对于优先级相同的进程而言，可以使得不同进程每次轮转的时间不同，从而使得目标进程（用户想让优先完成的进程）每次轮转时得到更多的执行时间，从而缩短目标进程的执行周期。用户可以根据实际需求，对进程的时间片权重进行修改，从而获得比较理想的执行周期。
