Worked on the geerlingguy/linux repository to refactor the iwlwifi driver, focusing on enhancing the modularity and configurability of the PCIe transport path. The approach involved moving the gen1_2 transport probe and related helpers into a dedicated source file, improving separation of concerns and maintainability. By externalizing txcmd_size and txcmd_align calculations from initialization routines, the refactor enabled more flexible hardware configurations and streamlined future optimizations. Utilizing C and leveraging expertise in driver development, embedded systems, and kernel development, the work reduced maintenance risk and laid a foundation for supporting future hardware generations without compromising stability or testability.
