furkanonder 98bf83f0e4 tools/rtla: Enhance argument parsing in timerlat_load.py [ Upstream commit `bd26818343` ] The enhancements made to timerlat_load.py are aimed at improving the clarity of argument parsing. Summary of Changes: - The cpu argument is now specified as an integer type in the argument parser to enforce input validation, and the construction of affinity_mask has been simplified to directly use the integer value of args.cpu. - The prio argument is similarly updated to be of integer type for consistency and validation, eliminating the need for the conversion of args.prio to an integer, as this is now handled by the argument parser.

RTLA: Real-Time Linux Analysis tools

The rtla meta-tool includes a set of commands that aims to analyze
the real-time properties of Linux. Instead of testing Linux as a black box,
rtla leverages kernel tracing capabilities to provide precise information
about the properties and root causes of unexpected results.

Installing RTLA

RTLA depends on the following libraries and tools:

 - libtracefs
 - libtraceevent

It also depends on python3-docutils to compile man pages.

For development, we suggest the following steps for compiling rtla:

  $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git
  $ cd libtraceevent/
  $ make
  $ sudo make install
  $ cd ..
  $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git
  $ cd libtracefs/
  $ make
  $ sudo make install
  $ cd ..
  $ cd $rtla_src
  $ make
  $ sudo make install

For further information, please refer to the rtla man page.
