性能启用拆解调用图

我在Ubuntu
15.10上遇到了相同的问题，并且在这里找到了解决方案：https

更新：也适用于Ubuntu 18.10

步骤如下：

sudo apt-get install libiberty-dev binutils-devmkdir ~/installcd ~/install# If the following apt-get doesn't work on your system,# uncomment deb-src lines in your /etc/apt/sources.list,# as suggested by @ctitze# or you can download it manually from packages.ubuntu.com# as @aleixrocks suggested in the comment belowapt-get source linux-tools-`uname -r`sudo apt-get build-dep linux-tools-`uname -r`cd linux-`uname -r | sed 's/-.*//'`/tools/perfmake# now you should see the new "perf" executable here./perf

还应该有一些方法来创建一个新的linux-tools-common软件包，以将其真正集成到您的系统中。现在，用您的新性能替代正式性能，只需设置PATH：

export PATH=~/install/linux-`uname -r | sed 's/-.*//'`/tools/perf:$PATH
