Rockstar🎓
Top SchoolJonathan Lemon is a seasoned kernel engineer and systems architect with three decades of experience building and shipping low-level software for UNIX, FreeBSD, Linux and networking platforms. He invented the kqueue event notification facility used across *BSD systems, has multiple patents and papers, and has driven kernel and timing-driver development at companies from Cisco and F5 to Meta, Aviatrix and now NVIDIA. Jonathan’s work spans TCP/IP, virtual platforms, precision time synchronization (including an OCP timecard kernel driver), and computer architecture, blending research-grade rigor from a PhD with pragmatic production delivery. Based in Bremerton, WA, he brings rare expertise at the intersection of OS internals and timing/telemetry hardware that few engineers possess.

Contributions summary:Jonathan primarily focused on developing a kernel driver for an Open Compute Project (OCP) timecard. Their initial contribution involved creating the foundational code for the driver, including defining PCI device IDs and registers. The user added support for accessing and managing serial ports for GNSS and atomic clock data, and integrated features related to I2C communication for IMU and oscillator bus support. Furthermore, the user implemented a debug file for reading TOD status and added the ability to set a clock offset.
