Worked on the intel/pti-gpu repository over two months, focusing on both reliability improvements and build system enhancements for Intel graphics metrics streaming. Addressed test flakiness by refining file I/O handling in C++ and improving diagnostics for hardware-path specific scenarios, particularly on BMG Panther Lake and XE drivers. Enhanced test infrastructure by clarifying error reporting and removing dead code, which increased determinism in validation workflows. Delivered features to standardize tooling, including updating the PTI SDK version and consolidating the metrics library into the core library using CMake. These changes reduced maintenance overhead and streamlined downstream integration for C++-based driver development.
