This patch superseds http://patchwork.ozlabs.org/patch/150161/, but does it in a different way. Since we don't have a way of selecting the thread implementation for external toolchains, and it sounds a bit too heavy to add new config options just for the sake of rt-tests, we instead simply add some help text to the rt-tests package explaining that NPTL thread implementation is needed.

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).
