oprofile 0.9.8在Ubuntu 12.10下与Pentium D故障
问题描述:
我想在运行Pentium D处理器(Dell OptiPlex-GX620桌面)的Ubuntu 12.10下使用oprofile 0.9.8。当我尝试像“operf LS”简单的东西,我得到oprofile 0.9.8在Ubuntu 12.10下与Pentium D故障
perf_event_open failed with Invalid argument
Caught runtime_error: Internal Error. Perf event setup failed.
Error running profiler
我有成功使用opcontrol下sudo的命令用定时器= 1(见下文)安装模块运行在传统模式下oprofile的。
似乎操作者在这种配置中不高兴 - 这是新的首选方法。
我已验证所有依赖包已加载。
在oprofile网站上,他们没有将pentium D作为单独的构架调用,因此不确定它是否使用普通的Pentium架构。
我到处搜索并找不到像这样报告的任何内容。在这里找出问题时,任何帮助都会受到赞赏。
P.S.当我使用opcontrol与传统模式下运行,我有一些成功:

不知道这是主要的问题,但该错误消息说 -
"Error: counter 0 not available nmi_watchdog using this resource. Try: opcontrol --deinit echo 0 > /proc/sys/kernel/nmi_watchdog".
为了摆脱这个你有禁用NMI看门狗内核参数。在Ubuntu上它通过grub
做 -
编辑
/etc/default/grub
并添加“nmi_watchdog=0”
到GRUB_CMDLINE_LINUX
。然后运行
sudo update-grub
并检查值与cat /proc/sys/kernel/nmi_watchdog
(应该是“0”)。如果需要,重新安装新的配置。
