Open Source Summit Japan & Automotive Linux Summit 2021

The libcamera project set off in 2018 to forge the future of cameras on Linux. It would make complex cameras easy to use, and create a new world of cameras where open source and SoC vendors could live together in peace. The future has now started. This talk will start with a short view of the past of cameras on Linux, and what libcamera set out to reform. The audience will learn the importance of libcamera, and how it is the camera stack that users will want to use on Linux. libcamera has started to collaborate with more vendors and is continuing to get more on board, fostering collaboration between the world of open source and SoC vendors. This presentation will serve as a guide on how we can, together, create a bright future of cameras on Linux.

Advanced Display interface solutions are often critical to design due a mismatch between System On Chips(SoC) and it’s associated application-specific display devices. A display interface bridge prevents this mismatch by converting application-specific display interfaces from SoC display controllers. The type of display interface bridge depends on the display interface bus used between SoC display controller and application-specific displays. Most of the modern Embedded SoC's and application displays are choosing MIPI DSI as a standard display interface bridge due to its interface advantages, lack of long-term availability of discrete MIPI DSI panels. So, what are these MIPI DSI bridges? How are these used in SoC display controllers? How are these used in application displays? This talk will address all these information by considering real-time solutions from NXP i.MX8MM, Allwinner R16, and TI DLP Projectors. After that, this talk explains how to incorporate new MIPI DSI Host, Bridges, Panels drivers/API's into Linux DRM Subsystem by converting MIPI DSI to RGB/LVDS/HDMI and vice-versa.
