Display Sharing in Heterogeneous Systems Using Linux as High Level Operating System
Explore display sharing in heterogeneous systems using Linux as a high-level operating system in this 42-minute conference talk by Devarsh Thakkar and Soumya Tripathy from Texas Instruments. Delve into the challenges and solutions for implementing display sharing in automotive, industrial, and medical industries, where safety-critical information must coexist with non-safety elements. Learn how to communicate display sharing information to the Linux display framework, provide flexible interfaces for partitioning display resources, and ensure safety between Linux and real-time operating systems. Examine a practical demonstration using TI's Linux display driver, focusing on device-tree based static resource partitioning and Linux display driver updates for mapping shared and owned resources with Linux DRM entities. Discover how to handle display sharing complexity within the display driver while maintaining compatibility with existing display servers and applications.
