Android OTA Updates - Andrew Boie, Intel
AOSP is distributed with the source code and tools for full (whole image) and incremental (binary patch) secure over-the-air (OTA) software updates, specifically an alternate boot target Recovery Console, the updater logic itself, and tools to create software updates. There is no publicly available documentation for how this mechanism is supposed to be integrated. This presentation will give a detailed end-to-end description of how software updates are created, digitally signed, and applied to the device. There will be a discussion on the plug-in architecture and Edify language which allows builders to customize the OTA updates with platform-specific features. This is an updated version of a talk presented at ABS in 2012, with details on new OTA features including block-level OTA updates in Lollipop.

Autonomous Navigation for an OMAP4 Nano-Drone - Grégoire Gentil, Always Innovating
This talk will introduce the problem of 3D positioning for a drone especially in GPS-denied environments. The talk will explain why usual odometry or any position algorithm based on standard consumer-level acceleration sensors can't really work. The talk will first focus on external sensors such as Kinect or UWB ulta-wide-band signal, which can be used to provide an accurate 3D position of a drone. The talk will then highlight computer-vision solutions that can be implemented on the drone itself: LKT optical flow, face and body tracking, SLAM algorithms. The limitations and implementation challenges will be highlighted and a brief overview of the hardware and software architecture will be presented. Last, a short demo of a flying nano-drone illustrating those solutions will be offered.

An Overview of the Kernel DMAEngine Subsystem - Maxime Ripard, Free Electrons
In the Linux kernel, DMA controllers are handled through a framework called DMAEngine, which provides an API for other device drivers to perform DMA transfers. While this framework is critical to some drivers and use cases, it is also fairly obscure and under-documented.

This talk aims at giving an overview of this kernel framework, using the knowledge gathered during the development of a DMAEngine driver for the Allwinner ARM processors and the writing kernel documentation for this subsystem. We will see the main aspects of it, the different features and the recent developments in this framework.

Tuning systemd for Embedded - Alison Chaiken, Mentor Graphics
Systemd is as big a disruption in userspace as device-trees were to the kernel. Newer kernels are tightly coupled with systemd via udev, cgroups and the coming kdbus, so projects that select recent kernels will need to learn how to optimize and configure systemd. Systemd's fully asynchronous initialization and complex dependencies are bewildering at first, but its modularity, plentiful tool suite and comprehensive documentation make the configuration tractable. Systemd provides simpler access to resource management via cgroups, and presents a convenient interface to control the kernel's capabilities privilege-granting system via its security features. Systemd-udev's deprecation of firmware loading and the recent removal of systemd-readahead will create a headache for some users, and are symptomatic of the embedded community's need to participate in systemd's development.

Build and Distributing SDK Add-Ons - Dave Smith, NewCircle
Building powerful device-specific features into your Android device is only half the battle. For application developers to easily take advantage of those features, they need to have them exposed through a custom SDK distribution. Google provides all the tools to do this within AOSP via the SDK add-on target. This target provides all the tools necessary to generate packages that you can distribute to Android application developers using the SDK Manager tools they are already familiar with to build and test their code.

In this session we will discuss some short background about how AOSP device targets are structure. Then you will learn how to take an existing AOSP device target, apply an SDK add-on build target, and techniques for distributing the result to application developers.

Fuzzing the Media Framework in Android - Alexandru Blanda, Intel
This presentation focuses on exposing a software testing tool developed with the purpose of fuzzing the media framework in the Android OS. Approaching this topic is of particular importance given the fact that currently there is little prior work done, that concerns the issue of fuzzing media content in the context of the Android OS. The main idea behind developing this fuzzing tool is to create corrupt but structurally valid media files, direct them to the appropriate components in Android to be decoded and monitor the system for potential security vulnerabilities. The main parts of the talk include: an introduction to fuzzing and the reasons that make media content an attractive target, an insight on the implementation of the tool and the testing campaign and a series of results obtained using this approach, including a number of CVE entries that were discovered during this process.

Using Intel Edison to Fuse Embedded Linux With Existing Drone Flight Controllers - Mark F. Brown, Intel & Joel Rosenzweig, Intel
Current hobby-grade UAVs (unmanned aerial vehicles or drones) utilize lower-end onboard microcontrollers for flight control and sensor acquisition. These flight controllers are built upon a range of operating system software, some utilizing a full RTOS, while others use custom bare-metal environments. With higher end SoC (system-on-a-chip) designs such as Intel Edison you can leverage mobile phone grade computing platforms on the UAV itself in conjunction with an existing flight controller. This fusion allows Edison to integrate seamlessly into open source stacks like Dronecode and existing flight controllers like PX4 or ArduPilot. This project will demonstrate how to leverage Intel Edison on a multi-rotor drone.

Buildroot: Embedded Linux for Small Devices and Makefile Enthusiasts - Stephanie Lockwood-Childs, VCT Labs
With the impressive success of the Yocto Project in persuading board vendors to maintain BSP layers for the Yocto/OpenEmbedded build system, one might wonder whether other embedded Linux build systems are destined to fade away. Such is indeed the fate for certain build systems, such as the LTIB project (formerly maintained by Freescale)... but not so for Buildroot! Buildroot lives on, with as active a community as ever (5246 commits by 183 committers during 2014). This presentation will focus on a couple of niches where Buildroot is especially appealing: working with with low-cost MMU-less hardware, and projects short on time with developers lacking in bitbake experience. The latter point regarding a low learning curve will be illustrated with a full example of customizing Buildroot via normal configuration, adding skeleton files, and adding a new package.

The Device Tree as a Stable ABI: A Fairy Tale? - Thomas Petazzoni, Free Electrons
The Device Tree has been used for many years on PowerPC, and propagated to several other architectures since then, most notably the ARM architecture. Bringing a number of benefits such as a hardware representation clearly separated from the kernel code, it has also been introduced as a promise of ABI stability by its proponents.

With the Device Tree, a device manufacturer is supposed to be able to write a Device Tree to describe its platform only once, and be sure that any kernel version shipped *after* the kernel version that was originally used to test the platform will continue to work, using the same Device Tree blob.

In this talk, we would like to discuss this ABI stability requirement: does it actually work? what problems is this causing to kernel development? are Device Tree bindings sufficiently reviewed to guarantee such a stability? are SoC and board.. (too short limit)

Chaining HALs - Hunyue Yau, HY Research
HALs on Android are shared libraries with well defined names for entry points. Like all shared libraries, they can be chained. Chaining HALs can allow reuse or debugging of existing binary only HALs. Many Android systems are based customization of reference designs or even repurposing existing off the shelf designs. Chaining HALs provide addition customization options to existing Android systems. Chaining HALs can provide an alteranative vendor delays and hesitation with customizing or fixing binary only HALs.. Customization on a HAL level can have added benefits such as keeping existing security models intact futher up the Android stack.

Utilizing the Android Open Source Project to Support Controllers for Single-Use Devices. (X-Ray Guns! Pew Pew!) - Ben Friedberg, SDG Systems
When is a Nexus 5 phone more than a multi-use communication device? When it's controlling an X-Ray gun! SDG Systems was approached by Tribogenics Inc to retrofit Google's Nexus 5 phone to act as a controller for their prototype X-Ray Florescence Processing (XRFP) gun. SDG was to pare AOSP 4.4 down to a single application and then to act as the brains of the gun, communicating with the various elements and controller boards to create a cohesive and user-friendly unit.

Throughout the project SDG came up against a series of interesting problems which Ben will lay out along with the solutions that they came up with. Some of these issues include: Pre-5.1 'kiosk' mode, simultaneous USB Host mode and charging, external video, reusing Android settings, retrofitting the status bar and statically linking against NDK libraries within Android Studio. Attendees will likely not be irradiated.

Teaching More Fish to Fly - John Hawley, Intel
In 2013, at the Embedded Linux Conference in Europe in Edinburgh, there was a race between a dog and a blimp. It was said that despite the dogs win, that the blimp had participated in the miracle of flight. In 2014 we started showing how the MinnowBoard can be lofted and show useful. In 2015 we just want to give an update on where we are at and what interesting projects are being done both with the MinnowBoard and other platforms in the UAV space. The talk is mainly targeting taking an off the shelf embedded platform, Minnowboard Max, and it's use in UAVs, specifically quad-copters. With the ability to do real time computer vision, as well as various GPIO capabilities we'll explore the directions that significantly more autonomous UAVs can take with Linux and embedded platforms using, mostly, off the shelf components.

Introduction to IEEE 1588 Precision Time Protocol (PTP) Using Embedded Linux Systems - Insop Song, Gainspeed
The IEEE 1588 Precision Time Protocol (PTP) is to synchronize the time between networked devices. PTP can help applications that are required tight time synchronizations, such as industrial automation and measurement systems, telecom and mobile network systems. There are few open source PTP implementations including linuxptp and ptpd. Also, Linux has an infrastructure for hardware supported timestamping that is critical to PTP implementation. In this presentation, Insop will first review IEEE 1588 PTP, Linux timestamping and network driver for hardware timestamping. He will then explain how to use linuxptp, one of PTP implementations, and share tips from his PTP experience.

Poky meets Debian: Understanding How to Make an Embedded Linux by Using an Existing Distribution's Source Code - Yoshitake Kobayashi, Toshiba
Poky has already become one of the most popular build system to make an embedded Linux environment. Poky refers to OpenEmbedded originally. However if you want to use other source code, how to do it? We have some experience we would like to share with you. For this study, We choose Debian source and already tried two ways to use it. The first try was probably an incorrect way and the second try may be a correct way.
In this talk, we will show both of them and also describe why we choose Debian. If you are interested in this implementation, you can download the source code from GitHub. There are some implementations available for development boards such as pandaboard, minnowboard and etc. Let's enjoy Bitbake!

Ready-Made Recipes to Add Security and Data - Dominig ar Foll, Intel
The Internet of Things (IoT) is growing fast and opens large opportunities to embedded Linux. Unfortunately traditional embedded Linux has been weak when it comes to security, private data protection and complex connectivities enabling. Importing Tizen security and connectivity models with Yocto layers enable to benefit from a long experience based on Mobiles, TV and Automotives. We will start by explaining what is Tizen architecture and how it provides Security and Connectivity facilities on top of a base Linux. We will then show how Yocto and Tizen-meta can be used to create embedded devices which benefit from several years of work done by the Tizen community. In particular we will review : - the mandatory access control enabling in an embedded device - the enforcement of good behavior by applications - resource access control - connectivity layers - Adding Apps after image creation.

Memory Management Internals - Karim Yaghmour, Opersys
The Android stack is fairly deep, with several key components impacting applications: the framework API, the system services, the virtual machine (be it Dalvik or ART), the native layer and the Linux kernel. Each of these components has an impact on the system's memory usage. Beside rules of thumb, there isn't much in terms of documentation on how the Android's internals manage and deal with memory.

This presentation will examine the Android OS' memory management, from the Linux kernel all the way up to the app layer. We'll discuss the features and limitations of every key component, how platform developers can navigate around those limitations and what to watch out for, and present the tools and methods available to understand each components' memory usage.

Automated Flashing and Testing for Continuous Integration - Igor Stoppa, Intel
Continuous Integration is a well understood and established practice for SW development, however it faces some fundamental problems, when applied to SW targeting many different platforms.

The only way to ensure support for each target platforms (both real HW and emulated) is to test it. And both deployment and testing of the SW must replicate closely what will happen in real life, barring gimmicks and workaround. Other important aspect is that the implementation must provide high scalability, so that developers can easily test their code prior to submitting it for continuous integration, on their local rigs, where possible, so that they can have direct access to the device under test.

The solution presented here uses off-the-shelf, inexpensive, HW components and confines platform-specific quirks to plugins that can be easily configured/extended, to support any platform.

Tizen: System-Wide Memory Defragmenter Without Killing Any Application - Pintu Kumar, Samsung
As we all know, physical memory gets fragmented over the period of time. With the smart phone era and the rich multimedia content, the problem seems to be more visible to the users. In the recent years there were many techniques and utilities developed that can either avoid or reduce the fragmentation or regain memory by killing the application and tuning some vm parameters. In this presentation I will showcase the techniques to quickly defragment entire system memory from user space without killing any application and bringing back the system memory to the initial state. I will also show how system responsiveness can be improved by using this techniques either from kernel space or user space.

Understanding Embedded Linux Benchmarking Using Kernel Trace Analysis - Alexis Martin, Inria
The increasing hardware and software complexity of embedded systems is a challenge for the design, debugging and optimization of applications. Benchmarking becomes a major technique in the validation of the correctness and in evaluating the performances of a system. However, as the number of benchmarking suites keeps increasing, it is a challenge to choose among benchmarks and fully understand the obtained results. For example, the Phoronix test suite contains about 200 test suites of which more than 70 test the CPU performance. A promising approach to understanding benchmark behavior is to use tracing. However, to provide useful information, developers need to choose what exactly to trace, choose a non intrusive tracing solution, manage big traces and succeed in analyzing the important quantity of captured data.

MLC/TLC NAND Support: (New?) Challenges for the MTD/NAND Subsystem - Boris Brezillon, Free Electrons
MLC and TLC NANDs are more and more common and almost inevitable for large capacity chips (> 2GB).
While this technology has been around for a couple of years now, it is only partially supported in the Linux kernel and is almost unusable in real products (for reliability concerns).
Supporting these chips implies not only reworking/extending the NAND framework (add scrambler support, implement read retry, ...), but also rework upper layers (UBI/UBIFS) to take MLC/TLC NANDs specificities into account (bitflip robustness, paired pages related issues, ...)

Through this talk, we would like to describe the MLC/TLC requirements, and talk about a few proposals to handle those requirements (these are either descriptions of existing submissions currently under review or recently merged, or just conceptual designs that would need further investigation).

Security Architecture in the IOT Age - Stephen Arnold, VCT Labs
Modern embedded Linux systems are now normally networked into a larger system, taking advantage of Linux's strength in networking. Unfortunately, embedded engineers all too often fail to spend enough time understanding and mitigating security risks faced by networked devices; recent CVE summaries for popular Linux home routers provide some glaring examples of insufficient attention to security. Today it is critical that embedded engineers increase their attention to security while developing products, rather than merely reacting to specific exploits discovered after release. A good starting point is to learn and apply security architecture best practices that have been documented over the years by system architects/engineers using a modern "system of systems" approach and the latest NIST standards, guidance, and risk management framework.

Platform-Level UI Customization - Karim Yaghmour, Opersys
In addition to being popular as a mobile OS, Android has increasingly been popular in the embedded world. Yet there's little to no information on how to customize one of Android's foremost features: its user interface. How can developers change the look and feel of the Status Bar or the Launcher (home screen)? How can they theme the OS? How can they create kiosk systems based on Android?

This presentation will walk embedded developers through how Android's user interface can be customized. We'll take each part of the user interface one by one, show how it's implemented, and demonstrate modifications to it. Examples will include the Status Bar, the Launcher, screen overlays, theming of the interface, theming the boot process, kiosk applications, etc.

The Syria Airlift Project: Open-Sourcing Humanitarian Airlift - Mark Jacobsen, U.S. Air Force
More than 240,000 civilians have faced siege tactics in Syria's civil war, and 4.5 million are considered hard-to-reach. Conventional airdrops are impossible because large aircraft are vulnerable to ground fire. The Syria Airlift Project is a grassroots effort to develop an alternative paradigm: swarming airlift, using large numbers of small UAVs to deliver low-mass/high-value goods like medical supplies. Our vision is to employ Syrian refugees in Turkey to assemble and operate these aircraft, in an uplifting, nonviolent effort to care for the countrymen they've left behind. In this presentation I will discuss our work thus far, how we are using open-source 3DR hardware and software for our unique missions requirements, and how we are bringing the principles of crowdsourcing to humanitarian airlift. I will also discuss the many challenges of preparing to operate in a conflict zone.

Last One Out, Turn Off The Lights - Geert Uytterhoeven
Recently, power management has been moving from system-wide power states to more fine-grained power control, saving more power and providing snappier user experiences (QoS). Modern devices are almost never turned off, even if battery operated. They are lurking in (partial) low-power states, always ready to process external requests.
At the hardware SoC level, this is done by organizing the various SoC components in complex topologies, controlled by power and clock controllers. Inside the Linux kernel, PM domains and the Generic PM Domain provide abstractions for various types of power and clock domains.
In this presentation, Geert will talk about recent advancements in the areas of PM domains and runtime PM. He will explain how to handle SoC power and clock domains in Linux, how to model them in DT, and how to ensure that (existing) drivers play well in a system using PM domains.

Android Customization: From the Kernel to the Apps - Cédric Cabessa, Genymobile
On Linux, you probably know how to expand your OS with new drivers, new packages, new SDKs, etc and develop an app that uses all those features.
With Android, the “all in one package” approach makes it easy for beginner to start writing apps, but harder to add new features to the OS
In this presentation, we explore the best ways to customize an Android system to let your applications benefit from a change in the low level stack.
We will visit every layers of the Android system (kernel, hal, jni, services, aidl, ...) and see how we can integrate our work into Android’s APIs in order to make it available to application developers.

Freedreno Status Report: Upstream and FOSS Graphics on ARM/SoC Devices - Rob Clark, Red Hat
Much progress has been made on FOSS graphics for ARM/SoC based devices in the last few years. Before you could only choose between no graphics or blob graphics on these devices, if you even had that choice! Freedreno has been leading the charge with an upstream gallium and kernel drm/kms driver. The result is the software you have come to take for granted on x86 now also works on ARM based devices (composited DE's like gnome-shell, wayland, games, webgl, and so on). Yet, there is much left to do. In this presentation, we will go into more detail about freedreno and discuss how the community can get involved: how to use, how to debug, and the remaining tasks for gl3/gles3 support. We will also demonstrate the current capabilities of the freedreno drivers on several Snapdragon based boards, such as the Inforce 6410 and 6540.

Building a General Purpose Android Workstation - Ron Munitz
In this tutorial, you will have a hands-on journey of customizing, building, and using a General Purpose Desktop variant of the Android-X86 project (Android-X86.org). The tutorial assumes previous experience with building Android off the AOSP, Android-IA, CyanogenMod, or any other build system, and describes the special additions of Android-X86, such as a Kernel build system, general X86 hardware detection based HAL's/firmware and live cd/disk installer generation and more. Then, we will explore the Linux friendly busybox minimal image, and describe the way a fully fledged Android version can be spawned out of it (with similar techniques for any other Linux distribution with the Android patches!) using chroot, and provide a listing of the ultimate Android init process.
We will continue the discussion with day to day uses, and a joint brainstorming of Linux developer uses, and justify Android-X86 as yet another X-less Linux distribution - until the time we add X to it...
As a special bonus, we will address how to make any app run using a user-QEMU based ARM translator (although we sure hope non "APP_ABI:=all" are quickly fading away from this world!)

Creating Platform Development Tools - François-Denis Gonthier, Opersys
Android platform development is challenging, even for the initiated. Part of this is due to inherent system complexity but part of it is also due to lack of documentation and appropriate platform-level development tools. Indeed, while Google does a good job a polishing app-developer tools, its platform tools are mostly undocumented and very uneven.

This talk will explain the work we've done on creating open source platform development tools for Android. We'll describe, for instance, how the popular Node.js framework can be used to create web-based platform tools such as the open source Opersys Process Explorer.

Regulators: Learning To Play With Others - Mark Brown, Linaro
Traditionally embedded Linux systems have been built on the basis that idea that the processor running Linux has full control of the system and can directly manage the hardware at all times. This has never been true for all systems and with modern power sensitive systems very often have coprocessors managing the lowest power states while Linux is suspended or idling CPUs. This especially affects the regulator API which must coordinate with these coprocessors to provide functionality in low power states, this is the main current driving force for development in the API.

This talk will provide an introduction both the the regulator API and current systems, then discuss approaches to extending the regulator API to get the best from these systems.

BoFs: Applying Linux to the Social Infrastructure Systems - Noriaki Fukuyasu, Linux Foundation
Linux has become one of the most important software to run the social infrastructure systems (SI system) such as power plants, water distribution and traffic control. From computer system viewpoint, the controllers require a very high level of real-time performance, reliability and security to avoid serious failure. To overcome the issues to apply Linux on SI systems, as the first step, we need to gather the actual requirements. Past few months, some companies who are interested in this area actually got together and discussed to put those requirements together. The requirements arose, for example, include the recovery time for redundant systems (less than a few milliseconds) etc.
In this talk, I would like to share the current status of this requirement discussion and our future collaboration plan.

Android Based Penetration Testing Framework - Ron Munitz
"Pentest" (Penetration Testing) is the somewhat Sisyphean art of finding the weakest link in the chain of end to end products such as Clients (Web, Mobile, others), DB, Servers, and a bunch of other software and hardware components. It only takes a single weakness to take down an entire project, and it's better be done in-house, then by some hostile adversary.

As the mobile apps have become the dominant way to consume data for many services, their nature, given the fully available "client" side via the different App stores can serve to simulate real load scenarios, with arbitrary client side scaling. In this presentation we will present an Android based Pentest framework that not only exhausts the server exposed control/REST APIs , but also the behavioral and data path in a fast, reliable, easy and scalable way, using customized distributed Android instances.

As opposed to solutions aiming to test the client side, this framework aims to test a real system under real loads.The audience is anyone interested in a general Purpose Android Operating System, in Linux, in ROM cooking, Android Build Systems and the likes.

Filesystem Considerations for Embedded Devices - Tristan Lelong, Adeneo Embedded
The goal of this presentation is to answer a question asked by several customers this year: which filesystem should you use within your embedded design's eMMC/SDCard? These storage devices use a standard block interface, compatible with traditional filesystems, but constraints are not those of desktop PC environments. EXT2/3/4, BTRFS, F2FS are the first of many solutions which come to mind, but how do they all compare? Typical queries include performance, longevity, tools availability, support, and power loss robustness. This presentation will not dive into implementation details but will instead summarize provided answers with the help of various figures and meaningful test results.

Digital TV Kernel Pipelines via Media Controller API - Mauro Carvalho Chehab, Samsung
The media controller API provides a way for the userspace to view and control the hardware pipelines used by media hardware. Initially developed for the Video4Linux subsystem, the media controller API is generic enough to be used by any Kernel subsystem that needs to allow seeing or controlling of the pipelines used for media streaming. On a customer's hardware there's only one possible pipeline, however, embedded hardware generally uses complex pipelines that require changes at runtime. Mauro will discuss the improvements planned for Kernel 3.20 to extend media controller support to the Digital TV subsystem.

Introduction to Kernel Power Management - Kevin Hilman, Linaro
In order to keep up with the complexities of SoCs, the Linux kernel
has an ever-growing set of features for power management. For the
uninitiated, it can be confusing how each of these features work and
even more confusing how they should work together. This talk will be
a high-level introduction and overview of each of the various
features, as well as discuss how all they fit together and interact.

Some of the features/subsystems covered: suspend/resume, CPUidle,
CPUfreq, clocks, regulators, runtime PM, generic power domains, PM

Transactional Device Tree & Overlays: Making Reconfigurable Hardware Work - Pantelis Antoniou, Konsulko Group
Device tree has been decreed as the modern way to describe a board's hardware, but falls flat when faced with the problem of hardware that it-self is reconfigurable. While this is more prevalent on systems employing FPGAs, it is actually a problem for low-end boards like the Beaglebone & any other device that exhibits flexibility in configuration its interfaces. Limitation of in-kernel DT support make it hard to apply batches of changes and revert in need be. The new Transaction Device Tree + Overlays patch-sets overcome these problems and are already part of the Linux kernel since 3.19. Pantelis Antoniou will review the extensive changes and will discuss the major changes coming in the DT support of the kernel.

Embedded Android Workshop - Karim Yaghmour, Opersys
While Android has been created for mobile devices -- phones first and now tablets -- it can, nonetheless, be used as the basis of any touch-screen system, whether it be mobile or not. Essentially, Android is a custom-built embedded Linux distribution with a very elaborate and rich set of user-space abstractions, APIs, services and virtual machine. This one-day workshop is aimed at embedded developers wanting to build embedded systems using Android. It will cover Android from the ground up, enabling developers to get a firm hold on the components that make up Android and how they need to be adapted to an embedded system. Specifically, we will start by introducing Android's overall architecture and then proceed to peel Android's layer one-by-one.

Status Report for IEEE 802.15.4 and 6LoWPAN in Linux (Stefan Schmidt, Samsung OSG) - This talk will put the spotlight on the linux-wpan project which brings IEEE 802.15.4 and 6LoWPAN support to the Linux Kernel. Designed for low power devices these protocols are ideal for the use of smart Things.

Over the last years IEEE 802.15.4 support has slowly found its way into the mainline kernel. The 6LoWPAN code is now shared with the Bluetooth stack and a new netlink interface has been merged together with new drivers. The matching wpan-tools userspace utility will be used to setup 6LoWPAN on your Linux system.

The ARM's big.LITTLE technology implements a smart idea of combining high-performance cores are with low power ones to deliver peak-performance capacity at a lower average power cost. However, as big.LITTLE effectively is an asymmetrical MP, mainline SMP-oriented kernel "fair" scheduler can't take advantage of it. This talk will show what should be changed in the mainline scheduler to fit big.LITTLE architecture.

Multiple attempts were carried out to come up with the improvements implementing these changes, with the most notable coming from Codeaurora and Linaro/ARM.

Improving the Embedded Linux Development Workflow - Paul Eggleton, Intel
The Yocto Project provides a standard way for embedded systems developers to build a customised Linux-based OS from sources, as well as being able to produce an accompanying SDK for application developers to use. However, up to this point there have been divisions between the worlds of the different types of developers working on the same project. With the increasing numbers of places Linux is going, such as drones and the wider Internet of Things, time to market is key and for that, interaction between the different types of developers is increasingly important. In this presentation, Paul Eggleton will describe some of the new tools and enhancements being developed within the Yocto Project to try to bridge the divide between the developer's environment and the OS image that ends up on the embedded device.

Shrinking C Code - Rob Landley
Professionally developed code can often be shrunk to less than half its original size with a few simple techniques. For example, when the toybox "ifconfig" command was submitted (written by a professional team of experienced developers), the code was 1504 lines (44268 bytes) in 38 functions. After cleanup, the same code was 521 lines (15963 bytes) in 4 functions.

This is a walkthrough of each of the 26 commits applied to shrink that code to 1/3 of its original size, explaining why each change was made and the underlying principles of code simplification.

Fixing the y2038 Bug - Arnd Bergmann, Linaro
It is widely understood that all existing 32-bit Linux systems will stop working 23 years from now in 2038, when time_t wraps around. A small group of kernel hackers is now working on fixing this problem and this presentation gives an overview of what the overall strategy is, which changes have been implemented already and what the main remaining problems are faced in the kernel and in user space. Going into more detail, Arnd Bergmann will explain his plans for addressing some of the harder problems inside of the kernel.

This is a must-see presentation for people working on embedded systems with an expected life of 20 years or more, such as automotive or medical equipment. A secondary audience is anyone interested in core kernel development and API design along with developers of toolchains and distributions that are going to be affected by the necessary changes we are doing.

The focus of this talk will be on early system bringup, but the tools and techniques used are applicableto all phases of system operation. Measurement of early system bringup has to  deal with a number of unique issues as compared to normal system profiling, due to the nature of the process and the lack of infrastructure in the early stages. Techniques will be demonstrated for optimizing the four main stages of system bringup, namely bootloader, kernel, init, and critical applications.

Community Involvement: Looking Forward and Looking Back - Deepak Saxena, Noted Linux Kernel Developer
 Linux has grown by leaps and bounds in the last decade, finding its way into billions of mobile devices and also into the core of cloud based services that we rely on for business, entertainment, and increasingly, security. With this explosion of devices, we have seen more companies get involved with the kernel community, some successfully, and some struggling. In this talk, we will look at some of the challenges that the industry and the community continue to face in working with each other and also more importantly think about what is next? The adoption of Linux will continue to increase throughout all market segments, bringing in numerous new organizations and new developers. How do we move forward and what changes need to happen within the industry and community cultures to work better together?
