An Introduction to Asymmetric Multiprocessing: When this Architecture can be a Game Changer and How to Survive It - Nicola La Gloria & Laura Nao, Kynetics

Asymmetric multi-processing (AMP) systems fulfill the need for high performance and real-time by combining the responsiveness of a MCU with the processing power of an application processor which runs a full OS.

This talk will present a technical overview on asymmetric multiprocessing platforms focussing on motivations, use cases and how to handle interprocess communication between MCU and MPU in practice.

Tools and strategies on how to develop software on such platforms will be presented, as well as debugging techniques which take into account the diversity and complexity of such systems. A case of study based on AMP architecture is analyzed. Low-latency tasks such as high-rate reading/sampling can be handled more easily and efficiently by the MCU core running a RTOS while data visualization can displayed by the Master core running a full Linux operating system.

Tips for Writing Good Tests for Linux - Tim Bird, Sony

As maintainer of the Fuego test framework, I see lots of bad tests. The goal of this talk is to help you write tests that are more robust, easier to automate, and shareable with others in the Open Source community.

This talk will review and compare different test writing frameworks, including kselftest, LTP, and Fuego, and describe each one's strengths and weaknesses. A basic introduction to writing a test in each one will be given.

This talk will present tips for writing good individual tests, including which framework to use, what the test output should be, how to deal with test dependencies, how to make the test results more analyzable and usable, and other practical issues.

Following these tips should help you improve your own QA efforts. But my hidden agenda is to get you to write tests that I can use in my own Linux projects.

Apache Spark and Apache Ignite: Where Fast Data Meets the IoT - Akmal Chaudhri, GridGain Systems

It is not enough to build a mesh of sensors or embedded devices to obtain more insights about the surrounding environment and optimize your production systems. Usually, your IoT solution needs to be capable of transferring enormous amounts of data to storage or the cloud where the data have to be processed further. Quite often, the processing of the endless streams of data has to be done in real-time so that you can react on the IoT subsystem's state accordingly.

This session will show attendees how to build a Fast Data solution that will receive endless streams from the IoT side and will be capable of processing the streams in real-time using Apache Ignite's cluster resources.

In particular, attendees will learn about data streaming to an Apache Ignite cluster from embedded devices and real-time data processing with Apache Spark.

An Unbiased Look at the Energy Aware Scheduler (EAS) - Vitaly Wool, Interstate Labs

The big.LITTLE ARM SoCs have recently become a primary choice for many consumer electronic devices requiring high computing capacity and aiming for lower power consumption at the same time. As big.LITTLE is a heterogeneous architecture it puts special requirements on the OS scheduler for efficient operation, and Linux's completely fair scheduler (CFS) is not a good match.

To make matters worse, there happened to be several competing implementations of a scheduler for big.LITTLE, and none of them ideal. The Linaro version, called Energy Aware Scheduler, however, has taken the lead and is now used in most Linux/Android powered devices, with some funky modifications from hardware vendors.

This talk will provide a description of the EAS essentials and how it compares to the alternatives, briefly cover its vendor variations and then concentrate on what's good and what's not so good in it.

Introducing the “Lab in a Box” Concept - Patrick Titiano & Kevin Hilman, Baylibre

Continuous Integration (CI) has been a hot topic for long time. With the growing number of architectures and boards, it becomes impossible for maintainers to validate a patch on all configurations, making it harder and harder to keep the same quality level without leveraging CI and test automation. Recent initiatives like LAVA, KernelCI.org, Fuego, (…) started providing a first answer, however the learning curve remains high, and the HW setup part is not covered.

Baylibre, already involved in KernelCI.org, decided, as part of the AGL project, to go one step further in CI automation and has developed a turnkey solution for developers and companies willing to instantiate a LAVA lab; called “Lab in a Box", it aims at simplifying the configuration of a board farm (HW, SW).

Motivations, challenges, benefits and results will be discussed, with a demo of a first “Lab in a Box” instantiation.

Impact of Platform Firmware on Linux Kernel - Megha Dey & Sai Praneeth Prakhya, Intel

The ubiquity of Linux coupled with the de-facto UEFI platform firmware calls for rigorous validation of their interaction. A bug in either the kernel's EFI subsystem or firmware itself might cause systems to crash or hang; for instance, memory regions belonging to the operating system being illegally accessed by firmware. In this presentation, we would like to discuss the specific instances of firmware bugs that have impacted the stability of the operating system and some potential solutions that could have eliminated these bugs altogether. Also, we would like to introduce LUV(Linux UEFI Validation); a unified framework of several open-source test-suites packaged into a cohesive and easy-to-use product that aims to help firmware developers uncover bugs in the implementation of UEFI firmware at critical levels of the software stack.

Flexible IoT Solutions Using Zephyr and JavaScript - Brian Jones, Intel

Due to their limited resources, IoT devices tend to be designed for a very focused purpose and can’t be used for much else. But what if you could have numerous modules, programs, testing tools, etc available on your IoT device? And the items you want to use could be loaded at run time rather than re-compiling? By storing these items in flash memory rather than precious ROM, JavaScript* Runtime for Zephyr* OS (ZJS) is able to run stored JavaScript at will. This allows you to do things like create distinct modes that the device can operate in. Or have it run entirely different programs based on your current needs and launch them on the fly. Run what you want, when you want, and only use only what you need.

In this session Brian will cover the core concepts, use cases, and provide demos to illustrate how it all works.

Easy, Reproducible, VM Building for Isolating Applications - Jonathan Creekmore, Star Lab

Embedded virtualization benefits IoT device manufacturers by providing strong isolation between application services; yet, creating VMs is harder than lumping all of your services into one environment, so virtualization tends to not be used. With the rise of Docker container technology, easily creating repeatable builds of isolated services can achieved. Docker also uses layering to minimize disk space usage for containers that are based on the same underlying layers. It would be nice to leverage a hypervisor's smaller attack surface to gain the stronger isolation guarantees that VMs provide. What if there were a way to create VMs as easily as building a Docker container while still minimizing the disk space required for multiple VMs that share a common base? Come find out how to convert your existing Docker containers into VM images that can be booted under the Xen hypervisor.

Drive your NAND within Linux - Miquèl Raynal, Bootlin (formerly Free Electrons)

NAND flash chips are almost everywhere, sometimes hidden in eMMCs, sometimes they are just parallel NAND chips under the orders of your favorite NAND controller. Each NAND vendor follows its own rules. Each SoC vendor creates his preferred abstraction for interacting with these chips.

Handling all of that requires some abstraction, and that is currently being enhanced in Linux! A new interface, called exec_op is showing up. It has been designed to match the most diverse situations. It should ease the support of advanced controllers as well as the implementation of vendor-specific NAND flash features.

This talk will start with some basics about NAND memories, especially their weaknesses and how we get rid of them. It will also show how the interaction between NAND chips and controllers has been standardized over the years and how it is planned to drive NAND controllers within Linux.

Embedded Linux Quality Assurance: How to Not Lie with Statistics - Wolfgang Mauerer, Siemens AG/OTH Regensburg

Embedded Linux drives an every-increasing number of appliances in many domains and applications, some even real-time and/or safety critical. Traditional quality assurance of such systems is based on testing and formal verification, but the huge amount of code and the rapid dynamics of the Linux ecosystem, as well as fundamental limitations of formal methods make these approaches unsatisfactory.

Statistical quality assurance for reliability, error rates, maximal latencies etc. is needed. We will discuss current best practises, how to design and run automated statistical tests that capture relevant information, and how to properly evaluate the resulting data. Practical real-world examples and recipes are played through using the open source R language. Most importantly, we identify common mistakes in (over-)interpreting statistical results and predictions that may eventually harm people.

Keynote: Connecting the Dots on All Things Great and Small - Kate Stewart, Sr. Director of Strategic Programs and Philip DesAutels, Sr. Director of IoT, The Linux Foundation; Chris Aniszczyk, COO, Cloud Native Computing Foundation

The complexity of architectures across all domains of the Internet of Things has grown with the increasing richness of the underlying connected products and services. The basic models of device and cloud have given way to new models that integrate device, edge, network, and cloud. Various open source projects have formed to fill the gaps in the story and as a result, we are starting to see the emergence of a cohesive system of interconnected open source components needed for this to happen. In this session, Kate and Philip will take you through the Linux Foundation's open IoT strategy to help you understand how it all fits together.

Measuring and Summarizing Latencies using the Trace Event Subsystem - Tom Zanussi, Intel

The RT-devel kernel has recently merged a patchset designed to replace the RT kernel's latency histogram feature with a new version built on top of a more generic 'inter-event' facility. This new 'inter-event' capability in turn builds on the general-purpose Trace Event subsystem, and is expected to be merged into the mainstream kernel at some point.

This presentation will describe the new capabilities from a set of real-world examples all the way down to the 'bare metal' of the event subsystem. It will also discuss how these new inter-event capabilities can be used with other tracing facilities, and will cover possible future tasks that can/should be done to up-level and in turn build further on this work.

Update My Board! - Mirza Krak, Endian Technologies AB

There are now well established open-source solutions to do software updates on your embedded Linux device that have been "battle tested", that we can collaborate on to make the complexity of software updates manageable. These projects usually come with an reference implementation using a popular community board (BBB or raspberrypi) which can be used for initial testing.

In this talk Mirza will present how to integrate a number of open-source software update solution to a custom board and go trough the steps necessary for each project, because in the end the hardship/easiness of integrating the project with your custom board could be the deciding factor when deciding which project to use.

The projects that Mirza will cover are:

- SWupdate
- Mender
- aktualizr (libostree)

Graphics Performance Analysis with FrameRetrace: A Responsive UI for ApiTrace - Mark Janes, Intel

FrameRetrace is the first fully open-source graphics performance analysis tool for OpenGL on Linux platforms. This talk will describe the current state of FrameRetrace, and why it is a compelling tool for OpenGL application and driver developers. A demo of FrameRetrace will illustrate and fix a performance problem in the mesa driver.

The following live experiments allow a developer to alter the frame and immediately see the impact on both performance and rendering:

shader editing and recompilation
changes to GL state settings
changes to uniforms values

Because FrameRetrace is built on top of ApiTrace, it can analyze most OpenGL applications. It can also provide parallel analysis of the same frame on Windows and Linux platforms, to highlight driver differences.

PREEMPT_RT, also known as "the rt patch" is a patchset ontop of the vanilla Linux kernel which helps provide bound timing guarantees for user task execution, a required property for any real-time application.

The rt patch has a long history out of mainline. What used to be a slow trickle of patches moving from the rt patch to mainline has now accelerated with the formation of the Real Time Linux LF project, which is actively funding the engineering work necessary to bring merge the patch into mainline.

However, long after the core PREEMPT_RT changes land in mainline, we'll still be stuck dealing with a long tail of problems in Linux's thousands of device drivers. The intent of this presentation is to describe the classes of problems in drivers which have detrimental impact to RT, why they cause issues on RT, and how they might be resolved."

A Solution to High Latencies Caused by I/O - Paolo Valente, Linaro

The BFQ I/O scheduler has made its way into the Linux kernel, bringing high responsiveness, low latency for time-sensitive applications, and strong fairness. These improvements are particularly beneficial for embedded systems, given the slower speed and the higher latency of the storage devices of these systems. Yet, some year may pass before major OSes for embedded systems, notably Android, will run recent-enough versions of the Linux kernel to enjoy these improvements. In this presentation, we show the benefits to come (or already available in systems running recent kernels), and compare them with the current latency and unfairness problems of Linux-based embedded systems. In particular, we show these facts through demos and numbers for real hardware.

Tock, The Operating System for a Programmable IoT - Amit Levy, Stanford University

Tock is an open-source operating system for low-power ARM Cortex-M microcontrollers that enables radically different kinds of embedded and IoT products.

In typical embedded systems, every line of code is fully trusted because embedded operating systems lack traditional isolation mechanisms like processes. Unfortunately, this makes developing secure products difficult, and running third-party applications virtually impossible.

Tock uses a language sandbox in the kernel and a process-like hardware enforced mechanism in userspace to isolate third-party and other untrusted code in the system.

In this presentation I'll introduce Tock's vision for IoT and how its isolation mechanisms work. Then, I'll use examples of deployed systems and products using Tock to show how developers can use it to build more secure and extensible IoT systems today.

Not Really, but Kind of Real Time Linux - Sandra Capri, Ambient Sensors

The problem: can a Linux system be constrained to deterministically control a task within some real-time-ish constraints? Sandra was tasked to use a Linux SBC to generate a pulse by asserting and deasserting a GPIO, accurate to within a fraction of a millisecond. Is it possible to control a task/thread/unit of control consistently on a standard Linux system without resorting to the Real Time patches?

There are thousands of modifications/configuration changes that one can do to a standard embedded Linux kernel, but determining which ones to modify to to give some semblance of real time control can be confusing.

This talk will illustrate what kernel configurations worked, and how kernel space code compared to user space code. Additionally, there may be other ways to skin this real time cat.

Results will be reported from work done on a Raspberry Pi as well as a BeagleBone Black.

The Salmon Diet: Up-Streaming Drivers as a Form of Optimization - Gilad Ben-Yossef, Arm

As Linux developers we know that up-streaming device drivers is a good idea for many reasons: maintainability, ease of customer access and even just doing the right thing.

There is however one more benefit less talked about: up-streaming makes your code better.

Since February 2017 my team has worked on up-streaming the than out-of-tree CryptoCell REE device driver, which existed and has been in active use and development for several years.

As part of this effort, we diligently followed the instructions of the community and mentors to bring the code to the desired quality and style and noticed a surprising pattern: almost each set of changes reduced the code line count, and yet the functionality stayed the same while the bug count decreased and we ended up with 30% less lines of code doing the same thing, yet better.

This is the story of this project and what can be learned from it.

Zephyr and MCUBoot as Foundations for Secure IOT Products - Marti Bolivar, Open Source Foundries

The Zephyr RTOS and its MCUBoot bootloader port are both active, fast-moving open source projects with the potential to bring a Linux kernel style development model and community to IoT.

However, while the components are well-documented, there's a lack of information on how to combine them to build complete, secure, updatable products with clearly stated threat models. This presentation aims to close that gap, by describing a concrete, open source IoT application based on Zephyr, MCUBoot, and LWM2M, as well as the developer tooling and security model underlying it.

The emphasis is on practical application of these tools, rather than an abstract discussion of the components themselves. Previous experience with Zephyr or MCUBoot is helpful, but not required.

Mixed Critical IoT Edge Systems Through Virtualization - Jérémy Fanguède, Virtual Open Systems

Not all the IoT objects are the same. Some of them treat sensitive data or impact the functionality of medical, safety and security devices in hospitals, cars, banks, etc. The growth of the IoT ecosystem and the achievement its objectives depends on the support of such devices and on their integration with the other objects.

During this presentation Jeremy Fanguède will present an architecture for the IoT edge, capable of supporting both high criticality (with real time and safety requirements) and low criticality devices through virtualization. More in particular, it will be shown how the co-execution of Linux, an RTOS (FreeRTOS) and a set of trusted APIs (OPTEE) is able to match the requirements of the next generation of IoT networks.

Debian for Embedded Systems: Best Practices - Vagrant Cascadian, Aikidev, LLC

Debian is one of the oldest Linux based operating systems in widespread use.

As embedded hardware becomes more capable, Debian becomes an attractive OS for projects. Debian provides clear licensing, a solid technical foundation, and over twenty-five thousand software projects already available within Debian.

Unfortunately, embedded system projects may make changes to a customized Debian OS in ways that make it difficult to apply security updates or system upgrades. This can lead to an unmaintained fork of Debian with long-standing security vulnerabilities unfixed in the hands of end-users. Nobody likes bit-rot.

Many of these common pitfalls can be mitigated or avoided entirely by understanding Debian's culture, infrastructure, technical norms, and contribution processes. These understandings will improve embedded systems using Debian over the long-term.

OSS License Compliance for Software Developers, NOT for Legal Experts - Satoru Ueda, Sony Corporation

Dealing appropriately with the OSS License is an essential issue using open source software. In this session, we would like to consider the most important things which are always forgotten especially for actual software developers. To be consulted by attorney or legal department staff? Of course it is important. However we mustn’t forget the existence of the engineers who are not supported by those legal experts. And there are some pitfalls which legal experts are always fall into. The role of the software developers who to use OSS are enormously important. Don’t be afraid! It is not so difficult for the software developers to perform the role.

Hyperscalable Unified IoT Platform - Drasko Draskovic & Janko Isidorovic, Mainflux

IoT middleware platforms have become necessary building blocks of every complex vertical IoT solution. Traditionally, the platforms have been built to run in the cloud; wide availability and rich capabilities have driven the first wave of IoT adoption. As the scale and complexity of IoT projects has grown, however, the need to provide solutions that move processing to the network edge has also grown. Down-scaling cloud capabilities is complex in part because of the more modest capabilities of edge computing in typical deployment models. As a result, there are few open solutions that address this need.

We introduce Mainflux (https://github.com/Mainflux/mainflux) - a IoT Platform for cloud and edge that can simultaneously scale-out to hundreds of nodes in the cloud, but can also scale down to a modest RaspberryPi computer without changing a single line of code. This scalability is achieved thanks to careful architecture, the effectiveness of Go programming language, and technology choices used in the implementation.

We will discuss the platform, its use and application, and our work to bring core concepts from it to various open source projects including EdgeX.

Making a Very Tiny and Efficient Library - Thiago Macieira, Intel

With the rise of IoT, came the resurgence of constrained devices: some restrictions have not been seen since the 1980s. There has been a lot of work done on Linux and other OSes small, but we will fall short of footprint requirements if we keep designing libraries like we have been for PCs and mobile phones. This session will review the motivations for having TinyCBOR in the first place and why use of a protocol designed for constrained systems is superior to more traditional solutions like JSON. Then it will talk about the design of the library itself and how the author achieved a modular and yet space-efficient approach. Topics will include parsing without memory allocation, zero-copy data access and coding for space. Most of the session will be dedicated to that last topic and will deep-dive into iterating the design, tools and even what to look for in assembly listings.

Using Fedora with OSTree for IoT and Other Embedded Platforms - Peter Robinson, Red Hat

OSTree is a distribution agnostic project to provide transactional system upgrades and rollbacks, as well as replicating content incrementally. This makes it perfect for embedded and IoT systems by enabling easy distribution of updates also makes it very hard to end up with an non-bootable system post upgrade.

OSTree on Fedora can handle multiple architectures providing for an architecture independant IoT and embedded platform that works in the same way and provides the same content across multiple architectures such as x86_64, ARMv7 and aarch64.

This talk will provide an overview of OSTree on Fedora in an IoT/embedded context and then a demo of a aarch64 SBC, such as a Raspberry Pi running Fedora IoT Atomic with a selection of IoT based applications running in docker containers. There will be a general demo with atomic updates to the OS and how updates/rollbacks work as well as a Q&A.
