top是比较经典的CPU计算方法,top的代码在androidm/system/core/toolbox/top.c下面,输出process的cpu使用率在print_procs里面,CPU的计算是proc->delta_time * 100 / total_delta_time 先看total_delta_time由: total_delta_time = (new_cpu.utime + new_cpu.ntime + new_cpu.stime + new_cpu.itime + ...

dump cpuinfo是Android特有的命令,dump cpuinfo命令的实现在androidm/frameworks/base/core/java/com/android/internal/os/ProcessCpuTracker.java类里面,方法是printCurrentState: 而printProcessCPU输出process CPU的使用情况: private void printProcessCPU(PrintWriter pw, String prefix, int pid, String label, ...
结论:进程的总Cpu时间processCpuTime = utime + stime + cutime + cstime,该值包括其所有线程的cpu时间。 参考代码(python2.7): class CpuProfiler(BaseProfiler): def __init__(self, pid, adb, loghd): BaseProfiler.__init__(self, adb)
