Summary
🤩
Rockstar🎓
Top SchoolMaxime Ripard is a Senior Principal Software Engineer based in Toulouse with 17 years of experience designing and shipping embedded and Linux-based systems. He combines deep low-level expertise (Linux kernel, device trees, U-Boot, DRM) with higher-level skills in Python and system administration, and currently applies that breadth at Red Hat. A long-time open-source contributor, Maxime has made notable upstream contributions to the Linux kernel (vc4/BCM2712 DRM support) and to libfdt/device-tree tooling used across RTEMS and U-Boot, improving hardware configuration and overlay handling. He founded and led Cerno, taught and developed trainings at Bootlin, and brings both technical leadership and hands-on driver development to complex SoC and multimedia projects. Known for pragmatic problem solving, he often bridges kernel internals and boot-time/device-tree plumbing to enable real-world board support. His background uniquely pairs formal embedded engineering with practical ops experience across kernel, userspace and Android environments.

Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:22 commits in 1 year 4 months
Contributions summary:Maxime primarily contributed to the U-Boot project by adding and modifying code related to device tree overlays, focusing on applying them and adding functionalities such as retrieving maximum phandles and path offset operations. They implemented functions for modifying and retrieving properties of device tree blobs, including a new iterator for property traversal. This work enabled more flexible board configuration and expansion capabilities within the U-Boot environment.

Linux kernel source tree
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:52 commits in 1 month
Contributions summary:Maxime's contributions primarily focus on supporting the BCM2712 processor within the Linux kernel's DRM subsystem, particularly concerning the VideoCore IV (vc4) GPU. They added support for new hardware components and functionalities like the DISP clock, improved HDMI controller support, and incorporated BCM2712's updated writeback writeback controllers. This work included modifications to existing device tree bindings and data structures to deal with architectural and register-level differences for writeback controllers, PixelValve units, and HDMI controllers.
