(BoFs) Hardware Trace in the Kernel - Pawel Moll, ARM

Sign up or log in to save this to your schedule and see who's attending!

Most "embedded architectures" (TM) provide non-intrusive means of obtaining diagnostic and performance data about the processor and the system. Known under many names like processor or hardware tracing, it used to be a domain of of very expensive, proprietrary software and hardware solutions (aka probes, trace boxes etc). It is about time to change this situation and provide means of accesing all these feature from the system itself. There were more or less (mostly less) successful attempts to implement "trace frameworks" in the past. The presentation will summarize those and describe the approach I am taking while implementing the framework and drivers for ARM CoreSight trace infrastructure. I want to highlight the opportunity we have to improve our visibility of the system and I am hoping for feedback regarding user expectations and desired interface.

Pawel Moll

Principal Engineer, ARM
I've worked with so called "embedded Linux" for more then ten years now, currently for ARM in Cambridge, UK as a Principal Engineer, with main focus on Linux developer tools, in all possible form and shape. My recent interest include performance analysis and optimisation. Every now and then I also act as a trainer on ARM software courses, write developer articles and give technical talks (including many LinuxCon Europe and ELC-E conferences).
