Worked on the amzn/amzn-drivers repository to enhance the correctness and stability of EFA kernel verbs, focusing on kernel-level reliability for high-performance networking. Addressed a critical bug by aligning Queue Pair send and receive queue depths with device command values rather than relying on raw work request values, ensuring accurate initialization and reducing the risk of misconfiguration. This fix resolved a key discrepancy in the EFA driver’s kernel verbs support, improving consistency between requested and actual queue depths. The work involved low-level programming and kernel development using C, with a strong emphasis on device driver reliability and robust networking infrastructure.
