Worked on the tenstorrent/tt-kmd repository to improve build stability and test reliability by addressing both CI/CD processes and kernel-level testing. Delivered a targeted bug fix in C++ that resolved an overflow and unsigned conversion issue in the dma_buf test, ensuring compatibility with GCC 11 and preventing build failures. Enhanced the continuous integration pipeline by introducing a dedicated GitHub Actions job written in YAML, which compiles tests independently to provide faster and more reliable feedback. These efforts reduced build noise, improved test isolation, and established a more deterministic development environment, supporting smoother releases and ongoing kernel development for the project.
