During December 2025, Firas Achkar focused on maintaining and improving the Xilinx/XRT repository by addressing kernel compatibility issues. He delivered a targeted bug fix in C that updated the Linux kernel version check, ensuring support for Linux 6.1.0 and resolving compile-time errors that previously blocked builds. His work involved careful Linux driver and kernel development, emphasizing code hygiene by removing trailing spaces and stabilizing the build process. Although the scope was limited to a single bug fix, Firas’s contribution improved the repository’s resilience to future kernel changes and reduced build failures, demonstrating depth in low-level systems and driver maintenance.
