As embedded Linux devices get more complex, many questions arise about the process of constructing these systems and how it can be improved. Can these complex systems be built more efficiently to reduce development time? How can developers be assured that these systems can be built reproducibly to ensure software supply chain integrity? Joshua will highlight two new features in the latest release of the Yocto project specifically designed to address these questions.
In today’s computer systems the level of complexity has risen such that when a task or response to an event takes longer than expected, it is not easy knowing what the culprit is. The Linux operating system contains several utilities that allows a user to see where things may be held up. This talk will cover many of these utilities and briefly explain how to use them. From the hardware latency detector to the latency tracers.
While it has been under development for years, the support for video CODEC accelerators has gain a lot of traction in past year. A formal specification has now been merge into Linux Media subsystem and staging control APIs and drivers now exist. This allow for blob free HW accelerated decoding on popular SoC like Allwinner, i.MX8 and Rockchip.
In this talk, Nicolas will give an overview of the decoding process using such hardware accelerators along with an overview of the user space API and how it’s used within multimedia frameworks.
Robot Operating System (ROS) 2 - How Open Source Software and Linux is Powering the Next Generation of Robotics Katherine Scott, Open Robotics Robot Operating System (ROS) is a set of mature free and open source software packages used by the robotics community to program robots. Recently ROS had its first major version upgrade in a decade to ROS 2. This new version introduces a number of changes and new features, many of which simplify the development process and allow users to build virtual robots without ever touching a piece of hardware.
Using MIPI DSI as Main Display Interface Marcel Ziswiler, Toradex AG The MIPI Display Serial Interface (DSI) is the de-facto standard display interface featured by modern higher-end SoCs. Lacking the long-term availability of discrete MIPI DSI display panels most embedded systems rely on bridge chips converting to more common display interfaces like parallel RGB, LVDS, (e)DP or HDMI. Our generic system concept relies on DSI adapter boards integrating various such bridge chips.
