Handling mixed criticality on embedded multi-core systems

This talk illustrates how to use the Jailhouse hypervisor for running Linux alongside an RTOS on modern ARM multi-core SoCs, aiming at building smarter devices for the automotive market.

Recently, the industry has shown a growing interest for executing activities with different levels of criticality on the same multi-core SoC. These could consist, for example, of non-critical activities (e.g., monitoring, logging, human-machine intefaces) together with safety-critical tasks. The rationale behind this interest is the continuous need for reducing the time-to-market as well as the design and hardware costs. This is particularly suitable for the automotive market, where new infotainment functionalities might be coupled with traditional safety-critical tasks (e.g. engine/brake control). In this talk, we will present our experience (grown through the HERCULES EU project) in using the Jailhouse hypervisor for executing the Linux general-purpose OS alongside an automotive RTOS on modern ARM multi-core platforms. Besides providing useful instructions for using Jailhouse, we will illustrate a library designed for easing the communication between the two OSs as well as some mechanism for limiting the interference on shared hardware resources. Finally, a short video of a simple demo will show the effectiveness of the proposed approach.

What is LinuxLab?

LinuxLab - Building smarter devices - is the conference on Linux, kernel, embedded, build systems, security, virtualization technologies and open source. LinuxLab is organized by Develer, the company who launched events like Better Software, Better Embedded, QtDay, PyCon and EuroPython.
