Mastering the DMA and IOMMU APIs - Laurent Pinchart, Renesas

Sign up or log in to save this to your schedule and see who's attending!

The DMA and IOMMU APIs receive too little love. Developers usually expect DMA memory management to just work and are not aware of the crucial importance of handling all details correctly. This results in reliability, portability, maintainability and performance issues, especially in embedded systems. This talk will describe the problems that the DMA API addresses and explain how to solve them with practical examples. Cache management, device tree support, CMA and IOMMU integration will be explained, and tips to address performance issues will be presented. If the audience shows interest for the topic the shortcomings of the APIs will also be discussed and attendees' feedback be recorded to serve as a base to develop future enhancements.
