Exporting Virtual Memory as DMAbuf - Challenges and Solutions

Explore the challenges and solutions for integrating legacy drivers and RTOS applications with Linux in this 50-minute conference talk by Nikhil Devshatwar from Texas Instruments. Delve into the concept of exporting virtual memory as dmabuf, a method for sharing buffers across different drivers. Learn about the implementation, advantages, and security concerns associated with this approach. Gain insights into various kernel frameworks, including device tree, I2C, V4L2, and DRM, as well as the integration of RTOS automotive vision applications with Linux. Discover how this proposed solution addresses issues in embedded systems and automotive chip support.
