Set of utilities for testing the real-time behaviour of a
Linux system.
All tools are simple C programs with no dependencies, except
the hwlatdetect utility, which is a Python script and
therefore requires the Python interpreter. It will only be
installed if a Python interpreter has been selected in the
Buildroot configuration.
Note that this package requires a toolchain built with the
NPTL implementation of the pthread API (this is always the
case with glibc/eglibc toolchains, but may not necessarily
be the case with uClibc toolchains, since the thread
implementation is configurable).
