32 ### 3.3、hrtimer34 > TODO: hrtimer 目前还是使用优先级链表的方式进行管理，在遇到任务的大规模并发时还是存在部分性能问题，待内核有一个统一的红黑树组件后，再进行优化36 hrtimer 为高精度定时器，需要重写其 weak 函数（需要对接到硬件定时器，否则默认走的是软件定时器，分辨率只有 os tick 的值）才能正常使用，其主要使用方法：40 hrtimer 的延时并不是 while(1)式死等，它会将一个线程挂起，睡眠多少时间后通过硬件定时器将其唤醒（注：延时 ns 并不是真的能准确的延时这么多，而是在保证性能的情况下尽可能的延时）49 hrtimer 还提供了一套 rt_timer 风格的 api
