The Embedded Linux Conference (ELC 2012) will take place on February 15 – 15, 2012 at Hotel Sofitel in San Francisco. ELC consists of 3 days of presentations, tutorials and sessions. There will be over 50 sessions during those 3 days. I’ll highlight a few sessions that I find particularly interesting. February 15 10:30 – 11: 30 – Profiling and Performance Measurement Techniques Using Linux Kernel Tools by Govindraj Raja, Software Engineer at Texas Instruments and Partha S Basak, Technical Manager at Texas Instruments. With ever growing features and functionality of Linux kernel, one needs methods to trace and profile parts of Linux kernel for various reasons like performance analysis, debugging etc. This presentation aims at providing an insight into few of these tools and their salient features. Supporting use case data as captured on open source OMAP4 pandaboard is also provided. 14:00 – 15:00 – The Yocto Project Overview […]

Grant Likely, owner at Secret Lab Technology, describe the current status of device tree (used to resolve ARM “hodgepodge” issue) and provides an example at Embedded Linux Conference Europe 2011. Abstract: In recent years, Linux has enjoyed immense success in the embedded market, and we’ve seen an explosion in the number of devices supported by the mainline Linux kernel. Traditionally, however, adding support for another embedded machine typically involved adding yet another board.c file to the kernel which more often than not was simply cut and paste from a similar board. As a result, board support code contains a huge amount of duplication and has become so huge that it is becoming unmaintainable. To move away from individual board files, several architectures have adopted the Device Tree method of encoding the hardware details into a data structure which can be parsed by generic initialization code and device drivers. This session […]
