Summary
👤
Senior🎓
Top SchoolDaniel Lezcano is a Senior Staff Engineer with 26 years of systems and kernel expertise, currently focused on power and thermal management for ARM platforms at Qualcomm and Linaro. He originated and maintains LXC, contributed namespace-based resource virtualization upstream at IBM, and continues to shepherd CPU idle, timer drivers and the thermal framework in the Linux kernel. His early work in life‑safety air traffic and satellite distributed systems instilled rigorous fault-tolerant and real‑time design practices that inform his kernel-level engineering. Notably, he implemented user-space thermal threshold notifications and refactored core kernel components for clearer maintainability, blending deep systems programming with a pragmatic focus on upstreamable solutions. Based in Toulouse, France, he is a steady open-source maintainer who specializes in consolidating fragmented power-management code into robust, generic frameworks.

Role in this project:Back-end Developer
Back-end DeveloperContributions:41 commits in 4 months
Contributions summary:Daniel's primary contributions center around extending the Linux kernel's thermal management framework. They implemented user-space threshold support, enabling notifications when temperature limits are crossed. This work involved modifying core thermal management components, including files related to thermal thresholds and the overall thermal core, along with corresponding netlink commands and events. The user also refactored code to correctly handle threshold boundaries and notifications, ensuring accurate temperature monitoring.
