The osnoise and timerlat tracers landed up in 5.14.
In addition to the tracing aspects, these two tracers also report performance metrics relevant to real-time. However, it is not easy to manually parse these metrics.
The rtla (real-time linux analysis) is a user-space interface for these tracers. It works by using the libtracefs to set up a tracing section and to collect data and trace information. It has an intuitive interface, and will also serve as the basis for the other real-time related tracers.
The idea is to present and discuss this new tool in this MC topic.
