The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.
Linux时间子系统之六：高精度定时器（HRTIMER）的原理和实现
WebHowever, we found two issues in the current version of the Linux kernel: the CPU affinity of some kernel threads cannot be speci fied; and the use of timer cascading (use of multiple hardware timers to count time) increases the worst -case response time of real -time tasks.

Webhrtimer Time Source – Hardware clock event – All timer events are One shot events – Recent expired timer will be triggered e.g. Tick with hrtimer support – tick_sched_timer – Periodic timer event by one shot hrtimer event – Current tick … Web30 mrt. 2010 · The hrtimer framework is implemented differently from the traditional timer API. Instead of buckets and timer cascading, hrtimers maintain a time-ordered data … Web10 dec. 2013 · Tried disabling hyperthreading in kernel options with noht which found out is just a boot and not run-time option. Using maxcpus=1 kernel option managed to lower interrupt requests from " : hrtimer_start_range_ns (tick_sched_timer)" from ~60 to ~30 on idle, but with no discernible improvement in power consumption. garage churchfields salisbury
