Webb至于simpleperf的原理，简单来说，现代CPU一般都带有一个叫做性能监视单元（PMU）的组件，这个硬件能够记录诸如cpu周期数、执行的指令数、缓存失效次数等等关键信息；Linux内核对这个硬件做了一层封装，通过 `perf_event_open` 系统调用把接口暴露给用户空间；这就是simpleperf工具的由来。 Webb2 mars 2016 · Kernel has a utility named perf to view CPU PMU event statistics. Perf supports raw event id or named event. Due to the difference architecture of CPUs, only a few events are common defined in kernel. All other events related to specific CPU architecture can only be accessed by using raw event id.
