There are some tools in side the kernel,

<kernel source root directory>/tools

perf is one of them.

In ubuntu I think the tools inside this folder is available as package linux-tools

How can I compile it form source and install it and run it?

    make 0=/path/to/build/dir -C <kernel source root directory>/tools/perf – limovala Oct 1 '13 at 4:48
  • That builds the tools and allows me to use those but how to build a similar package as official linux-tools deb? – Mikko Rantalainen Sep 11 '18 at 6:53
  • @MikkoRantalainen the build-instructions for all official deb packages are available online – umläute Sep 11 '18 at 11:10

    @umläute I mean, is it possible to build linux-tools deb package from vanilla kernel sources without applying extra patches or copying debian directories around similar to using distribution supported make-kpkg command to build vanilla kernel sources? – Mikko Rantalainen Sep 13 '18 at 7:52

Nowdays: make -C tools/ perf_install prefix=/usr/

I wanted to compile for a different architecture and this seems to work. I had hosttools from buildroot in the output/host/bin directory. Most people will have it there if using buildroot. I had to specify the LD and CC flag. So substitute with appropriate path and is the prefix for toolchain name.

make CC=<buildroot-dir>/output/host/bin/<arch>-gcc LD=<buildroot-dir>/output/host/bin/<arch>-ld -C tools/gpio/
