PROFILE
Krzysztof Czurylo
Worked on the torvalds/linux repository to deliver GEN3 RDMA enhancements focused on improving performance and observability in the RDMA/irdma subsystem. Developed GEN3 Control QP support with deferred completions, reducing head-of-line blocking and enabling more efficient asynchronous operation handling. Added GEN3 hardware statistics support by implementing a hardware statistics map and updating reporting functions to expose new performance counters. These features enhanced throughput and latency for GEN3-enabled systems while providing richer metrics for performance tuning. The work demonstrated depth in C programming, kernel driver development, and hardware interfacing, with an emphasis on networking and performance optimization in a production environment.
