Timeline For Embedded Linux - Chris Simmonds, Consultant, 2net Limited

Today, Linux is woven into the fabric of our technology. Things such as printers, routers, TVs and phones all have their own "Inner Penguin". Yet it was never originally intended to be used beyond desktop and server PCs. A lot of things had to happen before Linux could break out of the PC
environment and make its way in the world as a jobbing jack-of-all-trades. Since the early beginnings of embedded Linux in the late 1990's many people have contributed time and know-how that has resulted in today's Linux based embedded operating systems. This talk describes some of the key milestones and the events and people behind them.

LTSI: Long Term Stable Kernel and it's Testing - Tsugikazu Shibata, NEC & Hisao Munakata, Renesas

LTSI is kept providing Linux Kernel for Embedded Industry with long term support. Many of industry people involved with the activities and some companies using LTSI for real products. There were a number of discussion in LTSI about rack of testing because testing is a mandatory requirement for industry usage. As the next step of LTSI, we are trying to discuss with industry people how we will be able to improve the framework to share the testing. In the presentation, we will update this years LTSI version and also how we will be able to share testing among the industry and the community.

Small Business BoFs - Michael Opdenacker, Free Electrons

Conferences like ELC and ELCE are excellent opportunities for small embedded Linux companies to meet, exchange experience and know each other better. This makes it possible to cooperate on customer projects which are too big for a single company, and to take advantage of the specific skills of each partner. We invite small business owners and employees to join this Birds of a Feather session. Rather than having sequential company presentations which can cause unbounded latencies, participants will first be invited to open an Etherpad and share their company name, location and their core area of expertise. The BoF will continue with discussions sharing experience and solutions for dealing with customers, building the business and its reputation, managing projects and engineering resources, all this without having to sell one's sould to the Devil.

Fighting Latency: How to Optimize Your System Using Perf - Mischa Jonker, Synopsys

With increasing CPU speeds, other bottlenecks arise; e.g. branch prediction and memory latency. In this talk we’ll explore how to identify performance issues using perf, and how to take these bottlenecks away. We’ll discuss prefetching (both hardware and software), conditional execution, and how we can use the compiler to help us. Finally, we'll do an analysis of the resulting improvements using both simulations and actual RTL.

Linux From Sensors to Servers- When is Linux not Linux? - Jonathan Austin, ARM, Ltd.

It's possible to build Linux for tiny devices without MMUs through to enormous multi-core servers. But is there anything remotely similar about the resulting systems? Is it sane to run Linux on a micro-controller? This talk will compare the anatomy of a uClinux/noMMU system to 'normal' ones, specifically looking at the difference between Linux running on Cortex A, R and M-class cores (M-class support has recently arrived in mainline!). Areas covered will include: notable missing kernel features (eg fork()!), binary format support, shared libraries, multitasking and security, as well as some of the implications to userspace of these differences. It will also cover some of the possible improvements to the way Linux uses features of R/M class cores, hopefully provoking some discussion on, for example, how to make better use of the Memory Protection Unit (supported in 3.11).

LLVMLinux: The Linux Kernel with Dragon Wings - Behan Webster, Converse in Code Inc.

The LLVM project is an extensive compiler technology suite which is becoming commonplace in many industries. Technology built with LLVM is already shipped in millions of Linux devices as a part of Android/Renderscript. Increasingly it is becoming a big part of the development process for embedded projects, all the way up through to high performance computing clusters. This session will provide an update on the status of the LLVMLinux project; a project which is cooperating with both the Linux kernel and LLVM communities to build the Linux kernel with Clang/LLVM. This talk is for developers and system integrators who are interested in LLVM technologies and using clang to build the Linux Kernel.

Keynote - Embedded Build Systems Panel - Tim Bird, Sony Mobile; Ross Burton, Intel; Thomas Petazzoni, Free Electrons; Karim Yaghmour, Opersys; Jeff Osier-Mixon, Intel (Moderator)

Embedded Linux isn't like "normal" Linux, which is available in tidy little distros where someone else makes all the tough decisions about what gets included. In the embedded world, the developer decides everything from the system content to the method for building that
content into a cohesive package, and very often that same developer also makes decisions about the hardware. This is one busy developer. So in that context, the question of "which embedded Linux is best?" takes on many facets. Which kernel, which packages, and which drivers? Which build system is best, and under which circumstances? Should I start with Buildroot, use a pre-designed solution like Android, follow emerging standards like the Yocto Project, or just DIY - which even some large corporations do? This panel brings together a team of four seasoned embedded engineers to discuss how they make decisions and solve problems.

Panelists:
DIY: Tim Bird
Android: Karim Yaghmour
Buildroot: Thomas Petazzoni
Yocto Project: Ross Burton

Android on Non-Mobile Embedded Systems - Arnout Vandecappelle, Essensium

We've gotten used to building embedded systems based on Linux, but now Android is the new hype and now managers are asking why we're not using it. One good reason to use Android is to be able to reuse part of the GUI for a smartphone app. In this talk, Arnout Vandecappelle will describe such a project and the difficulties encountered to make it a true embedded system, including upgrades, watchdog, etc. The talk also shows another project where we chose to stay with a more traditional Linux/Qt system and the reasons for doing so.

Optimize DMA Configuration in Encryption Use Case - Guillene Ribiere, BayLibre SAS

This presentation describes how hardware instrumentation IPs embedded into the OMAP4 interconnect were used in order to debug and improve the performance of the system DMA. This system DMA was involved into a data encryption pipeline which was under performing in comparison to theoretical expectations prior to this analysis. Usual tools were first used: Tracing, Systemtap. However in such a use case where several hardware accelerators are first configured and then used in the data path in a data pipe lining fashion, such tools could not help to pinpoint the exact performance gap. In order to get visibility into what was happening, hardware tools called OCP watchpoint were activated and used. They allowed to identify issues in the system DMA configuration and to quantify the latency budget among the different contributors.

Using and Understanding the Real-Time Cyclictest Benchmark - Frank Rowand, Sony

Cyclictest results are the most frequently cited real-time Linux metric. The core concept of Cyclictest is very simple. However the test options are very extensive. The meaning of Cyclictest results appear simple but are actually quite complex. This talk will explore and explain the complexities of Cyclictest. At the end of the talk, the audience will understand how Cyclictest results describe the potential real-time performance of a system.

This presentation will be useful and understandable for persons of all levels of technical expertise.

(BoFs) Hardware Trace in the Kernel - Pawel Moll, ARM

Most "embedded architectures" (TM) provide non-intrusive means of obtaining diagnostic and performance data about the processor and the system. Known under many names like processor or hardware tracing, it used to be a domain of of very expensive, proprietrary software and hardware solutions (aka probes, trace boxes etc). It is about time to change this situation and provide means of accesing all these feature from the system itself. There were more or less (mostly less) successful attempts to implement "trace frameworks" in the past. The presentation will summarize those and describe the approach I am taking while implementing the framework and drivers for ARM CoreSight trace infrastructure. I want to highlight the opportunity we have to improve our visibility of the system and I am hoping for feedback regarding user expectations and desired interface.

Speakers
