Asymmetric Multiprocessing and Embedded Linux
Explore the intricacies of Asymmetric Multiprocessing (AMP) in Embedded Linux systems through this informative 46-minute conference talk presented by Marek Novak and Dušan Červenka from NXP Semiconductor. Delve into the perspective method of handling multiple dedicated CPUs in a System on Chip (SoC) and learn about Remote Processor Messaging (RPMsg), a thin layer built on top of the VirtIO component that facilitates communication between different CPU cores. Discover the current state of RPMsg in the Linux kernel and its counterpart implementation for cores running RTOS or bare-metal (RPMsg-Lite). Gain insights into user-space "access" layers for AMP, with a focus on the open-source Embedded Remote Procedure Call (eRPC) library. Benefit from Marek Novak's expertise as an NXP Semiconductor professional working on RPMsg and Remoteproc components, and learn from his experience as the author of erpc-imx-demos and rpmsg-lite repositories on Github.
