Linaro Update

www.linaro.org Slide 2

Why Linaro?

Increasing need for shared ARMv7/v8 software engineering Without working together fragmentation and duplication result

Standards for ARM implementations in different segments

(server, networking etc.) for Linux are often absent

SoC vendors seek to supply “OEM and distribution ready”

software stacks

In the last 2 years, Linaro has become the place for ARM

licensees to safely work together on new open source

technology development Very strong engineering team established

Significant pieces of upstream plumbing merged

Roadmap of technology development published

http://www.linaro.org/


Linaro Overview

Linaro is a not for profit engineering company that delivers

core Linux technology for the benefit of members

Our key goals:

Use shared investment to provide high ROI to members

Accelerate time to market for member products

Reduce fragmentation and resulting costs

Work closely with ARM to deliver Linux software and tools

for new ARM technology – big.LITTLE, server, ARMv8

Make ARM a leading architecture in open source



What does Linaro do?

Linux kernel on ARM SoC Focus on Consolidation &

Optimization

Latest ARM SoCs, Cortex-A series

ARM GCC toolchain: best in class Monthly builds

New ARM technology: big.LITTLE, 64-bit,…

Delivers upstream

LAVA, Test, Validation Continuous Integration framework

for Linux & Android

Focus on member SoCs Linux, Android & Ubuntu

Advance work on next Android kernel

Upstream Projects

Linaro Open Source Testing & Validation

Open Source Software traditionally has limited testing SoCs have commercial level software quality requirements

LAVA – Linaro Automated Validation Architecture An open source software test & validation platform

Populated only by Linaro members hardware

Provides Members Continuous Integration for daily build & testing

Smoke, System and Regression testing

Web dashboard for results and trends

Measures distribution quality & trends

Framework is open source

Linaro maintaining large and expanding farm of latest

Member SoC boards

Linaro Enterprise Group (LEG)

Members deliver optimized open-

source software for ARM servers

Reduces costs, eliminates fragmentation,

accelerates product time to market

Enables ARM Server vendors to

focus on innovation and

differentiated value-add



Engineering: Steering & Management

Member-directed engineering Technical Steering Committee (TSC) provides high-level direction

through requirements creation and review

LEG Steering Committee representative on TSC to help coordinate

work between LEG and core engineering

Members choose what teams their engineers are assigned to: aligned

with skills and strategic interests

Linaro engineering managers oversee day-to-day work

Engineers assigned to Linaro join a broad talent pool,

gaining technical and upstream interaction experience Knowledge diffused back into the member organization, enabling more

effective upstream interaction

Linaro continuously monitors engineering activities to ensure

work is valuable and directly useful to members



Engineering: Platform Group

The most direct short-term value Linaro provides: directly

runnable, fully-enabled builds for member platforms

Done to ensure Linaro engineering is highly effective, putting

everybody on the same platform, and exercising code in

production-like situations Test and benchmark WG impact on member hardware

Keep track of what's happening in the wider upstream world

At member's option, can be used to empower and support a

community build for a specific platform Monthly builds of tip Android and Linux

Hosting for binaries with conditional redistribution

Example: ST-Ericsson Snowball-focused Igloo Community website

http://igloocommunity.org



Linaro Member Management Partnership

TSC meets every 2 weeks, monthly members’ report, Linaro

Connect 3x and members’ meeting 2x per year

Linaro provides Android and Ubuntu images every month Images generated by Linaro infrastructure can be delivered

automatically to member sites (or member’s community sites)

Package update distribution available

Kernel and toolchain provided as required Latest stable kernel for boards, tested and validated in LAVA

Cross-linking between Linaro and member sites

Bug tracking and project management

Escalation route(s) for kernel and toolchain issues that

member sites cannot address (IRC, mail lists,…)



Key Benefits of Linaro Membership

Focus engineers on your differentiation, not on common

infrastructure

ROI from Linaro’s 100+ expert open source engineering team,

including kernel and other maintainers

Direct Linaro engineering priorities & activities via the Linaro TSC

Dedicated Linaro Landing Team to work on maintaining your SoC

BSP support at the Linux tip

Access to new ARM technology including Linaro’s Linux kernel

software for big.LITTLE product deployment (only for members at

present)

Your products used in Linaro and supported with Continuous

Integration and testing in the LAVA test & validation framework

Maintenance and support for gcc toolchain

Kernel, Linux and Android distribution builds for your SoC(s)
