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.

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.

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.

In this session we will look at how the chaining can be done along with the pitfalls with chaining a HAL. A simple chained implementation will be discussed to illustrate this.

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.

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.

However, optimizing and customing Linux to fit Cortex-M series comes with large engineering efforts, and in this session, we would like to share the experience about eliminating the general application and kernel footprint by means of modern techniques like Thumb2 tweaks, link time optimization, and automatic feedback directed optimizer.

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. We'll also describe how to create Java-based command line tools and package them as APKs by showing how the open source Opersys Reverse AIDL tool works.

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.
Please join us to improve Linux together and make the world better place!

BoFs: Kernel Wish List - John Stultz

For the last few years, its become a tradition for Linux desktop developers to present a Linux kernel wishlist, at the Linux Plumbers conference, which basically summarizes some of the features those developers see as needed. See examples here:

https://lwn.net/Articles/462076/

https://lwn.net/Articles/618333/

See I hope to present a similar wish list this year at Plumbers, but instead focusing on the needs of Android/mobile use cases.

Thus this informal BoF will try to pull together a number of Android builders, OEMs, and component vendors to collect feature requests, and find pain points with getting device support working with the Linux kernel. What things are folks having trouble getting upstream? What infrastructure is missing to more easily support what you're doing? Are there new hardware classes that are being ignored upstream? So come with your issues and lets add them to the list!"

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.

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.

Overcoming Obstacles to Contributing to Linux - Tim Bird, Sony Mobile

Many companies struggle with contributing to Open Source projects. This talk will identify key difficulties that many large companies face in making contributions, and provide tips and lessons learned for overcoming these obstacles. Some of the difficulties discussed will be: version gap, expertise problems (an example of which is the "proxy problem", wrongly-abstracted code, process mismatch, and social and attitudinal barriers.

This will not be yet another talk on CodingStyle, but a more high-level look at structural problems inside companies and the industry that prevent meaningful engagement within the open source community.

The goal of this talk is to help individual developers and companies identify and implement practices that will accelerate their participation in open source, so that they can enjoy more of the value of open source besides just the open code base.
