PROFILE
Carlos Caballero
During a two-month period, Carl Scab built foundational ETM trace decoding and performance analysis features for the google/perfetto repository. He developed a PerfTracker class to centralize performance tracking and introduced a memory-content-to-time mapping table, enabling detailed correlation of process timings with memory states. Carl established an ETM importer pipeline, implementing binary file parsing and memory mapping support in C++ and Python, and designed a decoder infrastructure for ETM data analysis integrated with the SQL engine. His work included comprehensive documentation and build system improvements, resulting in a robust, maintainable workflow for ingesting, decoding, and analyzing embedded trace data.
