Simultaneously Leveraging Linux and Android in a GENIVI compliant IVI System – Andrew Patterson

It is widely accepted that Linux is the operating system of choice when building a complex, in-vehicle infotainment (IVI) system. The ability to support and quickly integrate device drivers for features such as CAN, MOST, graphics accelerators, networking interfaces, and Bluetooth can result in key differentiators for any GENIVI compliant IVI-based system. But what if Android was introduced as a second operating system? This session multiple implementations integrating both Android and Linux on multicore SoCs sharing audio and video resources across both domains while maintaining GENIVI compliance. Implementations with and without hypervisor technology will also be presented.

Technology Evolution

• 300,000 new cars and trucks would be sold in the United States this year with no CD player

• Expected to grow to 15.9 million in 2019.

• Large population of older people who don’t want to give up their CD players : Change takes time

The case for Linux in Infotainment

Page 13: Simultaneously Leveraging Linux and Android in a GENIVI compliant IVI System

Why Move to Linux ?

Proprietary 1st generation automotive IVI operating systems are getting expensive to maintain and scale up

Linux is an Industry standard Facebook, Amazon, Twitter all Linux servers Android has a Linux Kernel

Wide choice of hardware platforms (SoC) SoC vendors increasingly “do Linux first”

Several Automotive Linux options GENIVI well established AGL (Automotive Grade Linux) ?

Overview of LXC

• OS-level virtualization method• Used to run multiple isolated Linux systems

– Can be different distributions

• A single kernel is shared• LXC does not provide a virtual machine

– provides a virtual environment that has its own process and network space

• The LXC project is hosted on SourceForge– http://sourceforge.net/projects/lxc/

• Userspace control tools are provided for Linux containers• LXC has been integrated into Mentor ATP

Page 30: Simultaneously Leveraging Linux and Android in a GENIVI compliant IVI System

Overview of LXC (Cont…)

Linux cgroups provide:

• Resource limiting: groups can be set to not exceed a set memory limit

• Prioritization: some groups may get a larger share of CPU or disk I/O throughput

• Accounting: to measure how much resources certain systems use for e.g. billing purposes

• Isolation: separate namespaces for groups, so they don't see each other's processes, network connections or files

• Control: freezing groups or checkpointing and restarting

Features of a Hypervisor solution

■ SoC Hardware resources shared between two or more operating systems

■ Multi-core CPU, GPU, Audio, Network, USB■ Independent reboot / fast boot options

■ ADAS, system start-up■ Low Overhead ( 1-4 % CPU)■ Privileges Management / Security

Virtualization or Containers?

Hypervisor Virtualization Linux Container

For - Scalable to multiple domains on a single hardware platform

- Faster boot-up time

- Available as part of Mentor GENIVI Linux

- Lower Cost- HMI Integration easier to

manage- Solutions in place for Android

and AUTOSAR

Against - Cost / proprietary licensed software solution

- Substantial porting effort for device drivers

- Boot-up time : Need to wait for Linux host

- Less domain isolation
