1RTLA: Real-Time Linux Analysis tools
2
3The rtla meta-tool includes a set of commands that aims to analyze
4the real-time properties of Linux. Instead of testing Linux as a black box,
5rtla leverages kernel tracing capabilities to provide precise information
6about the properties and root causes of unexpected results.

8Installing RTLA
9
10RTLA depends on the following libraries and tools:
11
12 - libtracefs
13 - libtraceevent
14 - libcpupower (optional, for --deepest-idle-state)
15
16For BPF sample collection support, the following extra dependencies are
17required:
18
19 - libbpf 1.0.0 or later
20 - bpftool with skeleton support
21 - clang with BPF CO-RE support
22
23It also depends on python3-docutils to compile man pages.
24
25For development, we suggest the following steps for compiling rtla:
26
27  $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git
28  $ cd libtraceevent/
29  $ make
30  $ sudo make install
31  $ cd ..
32  $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git
33  $ cd libtracefs/
34  $ make
35  $ sudo make install
36  $ cd ..
37  $ cd $libcpupower_src
38  $ make
39  $ sudo make install
40  $ cd $rtla_src
41  $ make
42  $ sudo make install
