Embedded Linux Conference 2014
San Jose, Ca
Laurent Pinchart
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, DMA 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.
