During September 2025, Tom Sela focused on enhancing the correctness and stability of EFA kernel verbs in the amzn/amzn-drivers repository. He addressed a kernel-level bug by refining the initialization of Queue Pair (QP) send and receive queue depths, ensuring these values were aligned with device command queue depths rather than relying on raw work request values. This adjustment reduced the risk of misconfiguration and improved reliability for high-performance networking scenarios. Working primarily in C and leveraging expertise in device drivers, kernel development, and low-level programming, Tom’s contribution provided a deeper level of consistency and robustness to the EFA driver’s kernel support.
