During August 2025, Darcari contributed to the geerlingguy/linux repository by addressing a critical reliability issue in power-domain handling within the Linux kernel. Focusing on C programming and kernel development, Darcari implemented a targeted bug fix for TPMI Power Domain Package ID retrieval, replacing physical ID-based resolution with topology_logical_package_id(). This approach ensured correct mapping of package IDs, even in cases with non-contiguous identifiers, and prevented invalid memory references that could compromise system stability. The work demonstrated careful debugging and precise, risk-limited changes, resulting in a clean, reviewable patch that improved the correctness and robustness of platform/x86/intel power-domain code.
