根据http://lbrandy.com/blog/2008/11/oprofile-profiling-in-linux-for-fun-and-profit/教程,我正在尝试使用以下命令查看 oprofile 的结果:
.opreport
我也试过:
.opreport -lt1
我得到的只是这个:
Using //oprofile_data/samples/ for samples directory.
um zero is not used
um one is not used
um x41 is not used
um x4f is not used
有谁知道这些奇怪消息的原因是什么?
