Perf profiling cannot be used if CONFIG_PERF_EVENTS is not enabled in the kernel configuration. Similar to other tools, like ktap, we can enable the right options automatically.

perf (sometimes "Perf Events" or perf tools, originally
|
|
"Performance Counters for Linux") - is a performance
|
|
analyzing tool in Linux, available from kernel version
|
|
2.6.31. User-space controlling utility, called 'perf' has
|
|
git-like interface with subcommands. It is capable of
|
|
statistical profiling of entire system (both kernel and user
|
|
code), single CPU or severals threads.
|
|
|
|
This will build and install the userspace 'perf'
|
|
command.
|
|
|
|
Your kernel must have CONFIG_PERF_EVENTS enabled to use perf
|
|
profiling. Buildroot automatically enables this in the kernel
|
|
configuration.

Use of this option implies you know the process of using and

compiling the kernel selftests. The Makefile to build and

install these is very noisy and may appear to cause your

build to fail for strange reasons.

This is very much a use at your risk option and may not work
|

for every setup or every architecture.
