This toolset was designed to facilitate the testing, monitoring, and
tracing of various things with virtual memory, pages, and slab objects.
It is an invaluable resource for identifying and analyzing
memory-related issues, such as leaks and bottlenecks, and can greatly
enhance one's understanding of memory utilization within a system.
The mm toolset includes:
- 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

[yann.morin.1998@free.fr:
- don't depend on linux, already a patch dependency
- don't set CC: default is based on CROSS_COMPILE
- no need to fully recheck at install time
- move the option for alphabetical ordering
- fix check-package

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.
