JIRA: https://issues.redhat.com/browse/RHEL-86051 commit a86150f310d7c986bb27c3633520336b67388afe Author: Tomas Glozar <tglozar@redhat.com> Date: Thu Mar 20 10:25:00 2025 +0100 rtla/tests: Test setting default options Add function to test engine to test with pre-set osnoise options, and use it to test whether osnoise period (as an example) is set correctly. The test works by pre-setting a high period of 10 minutes and stop on threshold. Thus, it is easy to check whether rtla is properly resetting the period to default: if it is, the test will complete on time, since the first sample will overflow the threshold. If not, it will time out.

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) 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.
