GENIVI Status and Next Steps

►GENIVI 1.0• Specification approved January 2010• Single implementation on Intel® Atom™ processor and based on the Moblin

Linux distribution.• Many requirements are not met in this implementation.

►GENIVI 1.X and GENIVI 2.0• In definition and discussion within consortium


Implementation options

Note: Android is not part of GenIVI


Preparing for ARM supportUbuntu

►The GENIVI 1.0 specification identifies the major packages used for the reference implementation.

• Total Packages: 324• Supported on ARM distributions: Ubuntu 297, Debian 3• Not supported on ARM: 24


Preparing for ARM SupportNew Kid on the Block - MeeGo

► MeeGo = Best of Moblin (Intel) and best of Maemo (Nokia)

► Both Moblin and Maemo will be replaced by MeeGo

► Single unified distribution supporting both Intel and ARM architectures

► First Code release: March 31, 2010 – Known as ‘Day 1’

► After Day1, Meego ‘reference user experiences’ for netbooks, handsets, Connected TV and In-Vehicle will be added

Freescale i.MX Processor Linux Approach

► A layered approach with the right selection of components to provide a common Linux stack that enables customers to easily migrate across i.MXSoCs and penetrate the markets that they want to engage in.

► Common board support packages (BSP) consisting of kernel optimizations, hardware drivers and unit tests; Customizations for specific target segments.

► Extensive portfolio of optimized multimedia codecs (ARM and Video processing unit accelerated).

► Common middleware with reuse from open source frameworks that enable integration of proprietary components also - multimedia framework plugins, power management, security/DRM, graphics (OpenVG/OpenGL-ES), connectivity.

► Leverage Chrome™, Ubuntu, Android and GNOME Mobile solutions

Freescale Multimedia Automotive Reference Sofware (MARS) Key Features

►Auto grade Linux• Boot Time Reduction• Boot Time Critical Services Architecture (BTCS)• Power Management

►Small Footprint Embedded GUI (Demo purposes – FB based)

►Media and Connectivity Features

►Status: Done on i.MX25

31


Boot Time Reduction

►Requirement: Splash screen within 1 sec.; User space execution 3-12 sec.

►Problem: Linux typically takes 10-20 sec. to boot into a GUI

►Solution: Speeding up system boot duration by• Optimizing bootloader

enable cacheslimited environment variables block sizeskip network and IDE detection

• Optimizing kernellimit kernel to minimum needscompile drivers used at a later point as modules

• Optimizing filesystemre-order driver, services and GUI initialization

Boot Time Critical Services Architecture

►A “Boot Time Critical Service” (BTCS) is setup very early during the boot process.

►The BTCS code and data is located at a reserved memory area not to conflict with bootloader and kernel.

►The BTCS is implemented as callback function that can be invoked from either the bootloader or the kernel.

►The BTCS can signal the bootloader or the kernel trough a “back-callback” (ossignal) function.

Freescale Automotive Reference Design Components

►Reference Hardware Board• i.MX51/53 EVK• Auto specific Reference design for MX53

►Ubuntu• Very popular and supported distribution• The MX51-EVK is supported in the Ubuntu 9.10/10.04 release. This makes the

MX51-EVK a very good candidate for initial porting of the 24 packages to ARM architecture.

►Freescale’s Automotive Grade Linux• Kernel specific features that provide:

Fast bootBoot time critical services to allow <60ms response time for incoming CAN messages

►Multimedia Automotive Reference Software (MARS)
