Understanding PREEMPT_RT (The Real-Time Patch) – ELCE 2012

Steven Rostedt, working at Red Hat, talks about Real-Time Linux at the Embedded Linux Conference Europe, in Spain on November 6, 2012. Abstract: The real-time patch (which provides CONFIG_PREEMPT_RT), has been around since 2005. Started by Ingo Molnar and maintained by Thomas Gleixner and several others, it has grown from a hobby RTOS into a very serious contender. Several distributions (Red Hat, SuSE, Debian, Ubuntu) supply a kernel version that includes this patch. The embedded world has started adding the -rt patch to their own devices that they ship. But do the embedded developers understand what the -rt patch supplies? Programming for real time, and especially when writing kernel code requires special knowledge to avoid real time traps. This talk will explain what the real time patch provides and special programming tips that will ensure embedded developers will get the best from their devices. He goes through the following key […]

Beaglebone: The Perfect Telemetry Platform? – ELCE 2012

Matt Ranostay, technical staff at Ranostay Industries, gives a presentation about a telemetry system based on Beaglebone at the Embedded Linux Conference Europe on November 5, 2012. Abstract: The author will discuss his ongoing and other team members efforts to develop hardware and software that reports sensor data to the community. This talk will be split into several parts a) types of useful sensors b) hardware design of Beaglebone capes c) and telemetry reports to Pachube/Cosm. Demonstrating that in the new world of cheap prototyping boards with I2C, GPIO, and SPI that anyone can setup a decent monitoring system for home security, automation, and weather reporting. There will be a live demo of prototype geiger counter + weather station. The audience targeted is the professional hobbyist who likes to hack on microcontrollers in their spare time. It will take little to medium knowledge of electrical engineering to follow this talk. […]

LinuxCon North America 2012 Schedule

LinuxCon (North America) 2012 will take place on August 29 – 31, 2012 at Sheraton Hotel & Marina, in San Diego, California. The event will be co-located with the Linux Kernel Summit, the Linux Plumbers Conference, and CloudOpen 2012. LinuxCon consists of 3 days of keynotes, business and developers related sessions as well as tutorials. There will be over 80 sessions and keynotes during those 3 days. I’ll highlight a few sessions that I find particularly interesting and related to embedded Linux, software development and ARM. August 29 10:45 – 11:30 – Life After BerkeleyDB: OpenLDAP’s Memory-Mapped Database by Howard Chu, Symas Abstract: OpenLDAP’s new MDB library is a highly optimized B+tree implementation that is orders of magnitude faster and more efficient than everything else in the software world. Reads scale perfectly linearly across arbitrarily many CPUs with no bottlenecks, and data is returned with zero memcpy’s. Writes are on […]
