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
- libcpupower (optional, for --deepest-idle-state)

For BPF sample collection support, the following extra dependencies are
required:

- libbpf 1.0.0 or later
- bpftool with skeleton support
- clang with BPF CO-RE support

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 $libcpupower_src
$ make
$ sudo make install
$ cd $rtla_src
$ make
$ sudo make install

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