Explore hypervisor-less virtio for real-time and safety applications in this conference talk by Maarten Koning from Wind River. Delve into the evolution of fixed-function embedded systems into intelligent edge devices and their integration with backend systems. Examine the challenges posed by Moore's Law and the increasing complexity of software in multicore SoCs. Learn about partitioning as a solution and the growing trend of Linux in edge devices. Discover the use case of KVM with core isolation for Time Sensitive Networking (TSN) offload, and understand the hypervisor-less virtio shared memory layout and scenarios. Gain insights into the performance of virtio MMIO with MS in hypervisor environments and draw valuable conclusions for implementing these technologies in real-time and safety-critical systems.
Hypervisor-less Virtio for Real-time and Safety in Intelligent Edge Devices
Overview
Syllabus
Intro
FIXED-FUNCTION EMBEDDED SYSTEMS ARE NOW INTELLIGENT EDGE DEVICES
INTELLIGENT DEVICES INTEGRATE INTO BACKEND SYSTEMS -- ITIOT CONVERGENCE Infusion pumps are becoming medical service platforms
THE PROBLEM ....
THE SITUATION ...
Moore's Law + Moore's Gap = Multicore SoCs
COMPLEXITY DUE TO INCREASED SOFTWARE
THE REMEDY ... PARTITIONING
MEANWHILE, THE SW TRENDSCAPE...
EDGE DEVICES WILL INCREASINGLY CONTAIN LINUX
REALTIME AND SAFETY WORKLOADS WITH UNUX
USE CASE: KVM WITH CORE ISOLATION FOR TIME SENSITIVE NETWORKING (TSN) OFFLOAD
