## Overview
Automotive Grade Linux (AGL) is a Linux Foundation Workgroup dedicated to creating open
source software solutions for automotive applications. Although the initial target for AGL
is InVehicle Infotainment(IVI) systems, additional use cases such as instrument clusters and and
telematics systems will eventually be supported. AGL has participants from the Automotive,
Communications, and Semiconductor Industries and welcomes contributions from individual
developers.
By leveraging the over \$10B of investment made in the Linux kernel and other open source
software projects, the AGL Workgroup:
Enables rapid software innovation for automotive suppliers to keep up with the demand
from consumers for better IVI experiences·
Utilizes the talents of thousands of open source software developers dedicated to
maintaining the core software in areas like the Linux kernel, networking, and
connectivity, used in systems across numerous industries
The goals of the Automotive Grade Linux Workgroup are to provide:
An automotive-focused core Linux operating system stack that meets common and
shared requirements of the automotive ecosystem with a broad community of
support that includes individual developers, academic organizations and companies.
A transparent, collaborative, and open environment for Automotive OEMs, Tier One
suppliers, and their semiconductor and software vendors to create amazing in-vehicle
software.
A collective voice for working with other open source projects and developing new open
source solutions.
An embedded Linux distribution that enables rapid prototyping for developers new to
Linux or teams with prior open source experience
This results in faster time to market by jump-starting product teams with reference applications
running on multiple hardware platforms.

## Document Scope
[comment]: May 28, 2015
The scope of this document is to define the architecture of the Automotive Grade Linux software
platform. The requirements are broken up into an overview of the Architecture and a description
of each of the layers in the architecture followed by the requirements for each module in the
various layers. The Architecture Diagram and the layout of the specification take into
consideration all of the components that would be needed for an IVI system; however the are
missing requirements for individual modules. As the spec continues to evolve those sections will
continue to be filled in.
The main goal of this document is to define the core software platform from which applications
can be built. As such, this document does not define application requirements except in a single
case (Home Screen). Application requirements will be developed by various projects that use the
AGL platform. Those application requirements can be used to drive new or revised
requirements into the platform.
At this time there is no plan to use this specification to create a compliance or certification
program. The specification is used as blueprint to guide the overall work of AGL and to derive
work packages for companies and individuals to complete in order to attain the goals of the AGL
Workgroup.
