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. 7 8Installing RTLA 9 10RTLA depends on the following libraries and tools: 11 12 - libtracefs 13 - libtraceevent 14 - libcpupower (optional, for --deepest-idle-state) 15 - libcheck (optional, for unit tests) 16 17For BPF sample collection support, the following extra dependencies are 18required: 19 20 - libbpf 1.0.0 or later 21 - bpftool with skeleton support 22 - clang with BPF CO-RE support 23 24It also depends on python3-docutils to compile man pages. 25 26For development, we suggest the following steps for compiling rtla: 27 28 $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git 29 $ cd libtraceevent/ 30 $ make 31 $ sudo make install 32 $ cd .. 33 $ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git 34 $ cd libtracefs/ 35 $ make 36 $ sudo make install 37 $ cd .. 38 $ cd $libcpupower_src 39 $ make 40 $ sudo make install 41 $ cd $rtla_src 42 $ make 43 $ sudo make install 44 45For further information, please refer to the rtla man page. 46
