Worked on improving the stability of the graphics subsystem by addressing a race condition in the nouveau driver within the geerlingguy/linux repository. Focused on kernel development and driver debugging, the contribution involved implementing memory barrier operations in C to ensure semaphore writes completed before kernel wake-ups, thereby preventing premature wake-ups and reducing the risk of kernel stalls under interrupt-heavy workloads. This targeted bug fix enhanced system reliability, particularly in memory- and interrupt-intensive environments. The work demonstrated a strong grasp of kernel synchronization primitives and memory barriers, delivering a well-documented patch ready for integration across dependent open-source environments.
