Your kernel's Performance Events Subsystem does not support your processor type.Please use the opcontrol command instead of operf.解决方案：
下载源代码，安装 0.9.9的版本

/home/tomren/Downloads/oprofile-0.9.9/libutil++/bfd_support.cpp:638: undefined reference to `bfd_elf64_powerpc_vec'
/home/tomren/Downloads/oprofile-0.9.9/libutil++/bfd_support.cpp:638: undefined reference to `bfd_elf64_powerpcle_vec'解决方案：
下载 oprofile 的 1.1.0 版本，替换 libutil++bfd_support.cpp 中 bool bfd_info::get_sunth_sumbols() 函数。（只替换关于 "elf64_powerpc" 的判断即可）

遇到问题：无法正常启动
[tomren@localhost Test]$ sudo opcontrol --start
/bin/opcontrol: line 1263: echo: write error: Device or resource busy解决方案：
It seems that somehow oprofile has gotten into a weird state on your system. I suggest doing the following: 1. Reboot the system 2. rm /root/.oprofile/daemonrc 3. rm -rf /var/lib/oprofile 4. Setup and run oprofile again执行 2 可以解决
