docs: zh_CN: get rid of basic_profiling.txt
Changeset5700d19748
("docs: Get rid of the "basic profiling" guide") removed an old basic-profiling.txt file that was not updated over the last 11 years and won't reflect the post-perf era. It makes no sense to keep its translation, so get rid of it too. Fixes:5700d19748

|
|
||||||
|
|
||||||
<test> 用于表示要测量的目标
|
|
||||||
请先确保您已经有正确的System.map / vmlinux配置!
|
|
||||||
|
|
||||||
对于linux系统来说,配置vmlinuz最容易的方法可能就是使用“make install”,然后修改
|
|
||||||
/sbin/installkernel将vmlinux拷贝到/boot目录,而System.map通常是默认安装好的
|
|
||||||
|
|
||||||
Readprofile
|
|
||||||
-----------
|
|
||||||
2.6系列内核需要版本相对较新的readprofile,比如util-linux 2.12a中包含的,可以从:
|
|
||||||
|
|
||||||
http://www.kernel.org/pub/linux/utils/util-linux/ 下载
|
|
||||||
|
|
||||||
大部分linux发行版已经包含了.
|
|
||||||
|
|
||||||
启用readprofile需要在kernel启动命令行增加”profile=2“
|
|
||||||
|
|
||||||
clear readprofile -r
|
|
||||||
<test>
|
|
||||||
dump output readprofile -m /boot/System.map > captured_profile
|
|
||||||
|
|
||||||
Oprofile
|
|
||||||
--------
|
|
||||||
|
|
||||||
从http://oprofile.sourceforge.net/获取源代码(请参考Changes以获取匹配的版本)
|
|
||||||
在kernel启动命令行增加“idle=poll”
|
|
||||||
|
|
||||||
配置CONFIG_PROFILING=y和CONFIG_OPROFILE=y然后重启进入新kernel
|
|
||||||
|
|
||||||
./configure --with-kernel-support
|
|
||||||
make install
|
|
||||||
|
|
||||||
想得到好的测量结果,请确保启用了本地APIC特性。如果opreport显示有0Hz CPU,
|
|
||||||
说明APIC特性没有开启。另外注意idle=poll选项可能有损性能。
|
|
||||||
|
|
||||||
One time setup:
|
|
||||||
opcontrol --setup --vmlinux=/boot/vmlinux
|
|
||||||
|
|
||||||
clear opcontrol --reset
|
|
||||||
start opcontrol --start
|
|
||||||
<test>
|
|
||||||
stop opcontrol --stop
|
|
||||||
dump output opreport > output_file
|
|
||||||
|
|
||||||
如果只看kernel相关的报告结果,请运行命令 opreport -l /boot/vmlinux > output_file
|
|
||||||
|
|
||||||
通过reset选项可以清理过期统计数据,相当于重启的效果。
