kernel: hrtimer: interrupt took 412880 ns? Nov 4 04:15:30 sdw04-1 kernel: hrtimer: interrupt took 412880 ns 昨日我们的GP系统的一个节点出现了网络丢失,导致一个实例异常,翻看日志,有这么一条信息。从监控上看当时主机和网卡均有活动信息,欢迎大佬解惑。 环境信息:redhat6.5 回答 邀答 关注2 评论 参...
__hrtimer_start_range_ns-->HRTIMER_SOFTIRQ-->run_hrtimer_softirq-->hrtimer_peek_ahead_timers-->__hrtimer_peek_ahead_timers-->hrtimer_interrupt hrtimer_interrupt函数的前半部分和低精度模式下的hrtimer_run_queues函数完成相同的事情:它用一个for循环遍历各个时间基准系统,查询每个hrtimer_clock_base对应红黑...
expires_next = ktime_add_ns(now, 100 * NSEC_PER_MSEC); else expires_next = ktime_add(now, delta); /* 强制对定时事件设备进程重新编程,否则收不到arch_timer中断了 */ tick_program_event(expires_next, 1); pr_warn_once("hrtimer: interrupt took %llu ns\n", ktime_to_ns(delta)); } ...
pr_warn_once("hrtimer: interrupt took %llu ns\n", ktime_to_ns(delta)); } 高精度模式下中断处理程序也是通过直接调用__hrtimer_run_queues函数处理所有“硬”定时器的,并且也是通过激活HRTIMER_SOFTIRQ软中断来处理所有“软”定时器的。不同的是,在高精度模式下,底层的定时事件设备一定是工作在单次触发模式...

楼主把这虚拟机的内存扩大到1G试试吧，默认的是256M，我情况和你一样，调大了就可以了，哈哈……

printk_once(KERN_WARNING"hrtimer: interrupt took %llu ns\n", ktime_to_ns(delta)); } 3. 切换到高精度模式 上面提到,尽管内核配置成支持高精度定时器,但并不是一开始就工作于高精度模式,系统在启动的开始阶段,还是按照传统的模式在运行:tick_device按HZ频率定期地产生tick事件,这时的hrtimer工作在低分辨率...
