	  - page_owner_sort: userspace helper to sort the output of
	  /sys/kernel/debug/page_owner, which helps to know who
	  allocates the page from kernel context

	  - slabinfo: the tool which gets reports about slabs, for
	  example show empty slabs, modify of slab debug options at
	  runtime, display all information about a slabcache

	  - page-types: a handy tool for querying page flags

	  These tools are available only from kernel version 3.4.

	  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.

	  These tracers allow performing latency analysis, for which the
	  rtla tool provides wrapper commands to visualize and extract
	  latency traces and reports.

	  rtla includes three tracers, which have been introduced in
	  different kernel versions:
	    - Linux 5.19 introduced the osnoise and timerlat tracers,
	    - Linux 6.3 introduced the hwnoise tracer

	  osnoise and timerlat are always installed, while hwnoise is
	  installed if your kernel is recent enough.

	  Note: rtla in kernels before 5.19 had additional dependencies,
	  not available in Buildroot, so only rtla in kernels 5.19
	  onwards is actually supported in Buildroot.

	  Use of this option implies you know the process of using and
	  compiling the kernel selftests. The Makefile to build and
