Worked on the geerlingguy/linux repository to address a targeted bug in the AMD-pstate kernel driver, focusing on CPPC.min_perf enforcement during governor transitions. The solution ensured that the minimum performance constraint is correctly applied in active mode, even when cached frequency values remain unchanged, thereby improving the reliability of performance and powersave switching. This work involved in-depth kernel development and driver tuning using C, with careful validation of kernel interactions to align with performance governor semantics. The fix enhanced the predictability and stability of power and performance transitions for systems relying on dynamic CPU frequency scaling, reflecting strong attention to detail.
