During July 2025, Harry Cutts developed an end-to-end kernel input event tracing enhancement for the google/perfetto repository, focusing on expanding trace data coverage and improving kernel-level observability. He introduced a Protocol Buffer definition for Linux evdev input events, enabling accurate recording and tracing of these events within the system. By integrating the new proto into both build configurations and the trace packet definition, Harry ensured seamless capture of kernel input events from source to trace output. His work leveraged C++ and proto, drawing on expertise in build systems and embedded systems, and provided a robust foundation for deeper kernel event analysis.
