Simplifying First-boot Experience for Your Cloud VMs with Cloud-init - Ashish Sahu, Microsoft
Cloud-init may have started out as a way to customize the Amazon EC2 instance at first boot but it is now widely supported on every major Linux distribution and across many public and private clouds. With Cloud-init, you can perform any type or number of actions as it boots up on your favorite cloud - as it is designed to to run during the first boot, you don't really any additional steps or software to start utilizing it today. Join me in this demo-filled session to learn all about Cloud-init and how you can use it to customize/personalize your cloud VMs even before you log in to them for the first time!

Container Live Migration - Adrian Reber, Red Hat
One of the main reasons Checkpoint/Restore in User-Space (CRIU) exists is to enabled container live migration and although container live migration is always viewed as an outlier or corner case of containers, because containers are supposed to be stateless, CRIU continues to get better at container live migration. Maybe containers are supposed to be stateless, but CRIU still sees growing interest in its container migration features and especially the integration in container runtimes. In this talk I want to present details about CRIU and with which clever tricks it provides the ability to checkpoint and restore processes and whole containers. I also want to show how it is integrated in container runtimes like runc, crun, lxc/lxd, borg and Podman. I want to close the talk with a few demos showcasing CRIU's features in Podman as presented before to live migrate containers and how to use checkpoints to decrease the container startup time. The goal of this talk is to give a technical presentation how containers can be live migrated, that it is easily possible to live migrate containers and that the container migration technology has additional use cases.

Forging a New Open Source Hardware Contributor Model - Mark I. Himelstein, riscv.org
RISC-V International stands on the shoulders of giants. From Linux and Apache and Hadoop to OpenPower and OpenSparc and MipsOpen and more,we have benefited from all that came before us and from the astounding hi-tech renaissance of the last 20 years. The Open Source Software culture was hard fought and found its way to a contributor model where it attracts the best and the brightest contributors. The largest Open Source Hardware projects have largely been based on a volunteer model coupled with a pay-for-dev model. This talk intends to provide historical context of how the industry arrived at this Open Source Hardware model, why it has to change, and how we intend to begin that journey. All Open Source Hardware organizations and projects can benefit from this talk as we lay a framework of change and community that derives the best of what Open Software has brought us in a way that is sustainable and scalable. This will also be a call to action for all Open Source Hardware communities to take the steps to apply the lessons learned form the past and enable companies and individuals to achieve the same kind of product benefits and recognition we appreciate in Open Source Software.

Upstream First is Our Principle - Toward Super Long-Term Support - Masashi Kudo, Cybertrust Japan Co., Ltd. & Chris Paterson, Renesas Electronics Europe
CIP (Civil Infrastructure Platform) project aims to support industrial-grade systems by fulfilling the required level of reliability, sustainability, and security during their life cycles which are long, typically more than 10 years. CIP kernel and test teams are working to provide and maintain Linux kernel to sustain CIP activities overall. In order to sustain activities for such a long period, the teams adopt "Upstream First" as development principle. The “Upstream First” principle allows patch commits only if those patches are already in the upstream. Having both pros and cons, this principle turned out to be crucial and essential to continue releases and maintenance. The CIP kernel team works with Linux Kernel LTS and other open source projects to share its findings and contribute outputs. The CIP test team has strengthened automated testing systems for CIP by working with KernelCI and LAVA. This presentation updates activities of the CIP kernel and test teams which follow the "Upstream First" principle, and features collaborative works with Linux Kernel LTS, KernelCI and LAVA.

Evolution of Suspend-to-Idle Support in the Linux Kernel - Rafael Wysocki, Intel
Suspend-to-idle is a system-wide suspend variant which in principle does not rely on platform support. The suspend-to-idle control flow does not take non-boot CPUs offline and expects all CPUs to enter idle states through the idle loop, like in the working state of the system. However, it assumes that the scheduler tick will be stopped on all CPUs and the timekeeping will be suspended, which is a source of significant complications. It also expects system wakeup devices selected by user space to be functional and it needs to prevent all of the other interrupt sources from waking up the system. In some cases one interrupt source can signal both wakeup and non-wakeup events, so it is necessary to distinguish the former from the latter. All of that together causes the suspend-to-idle support code in the Linux kernel to be quite complex, especially on systems using ACPI, and that code has changed for multiple times in response to additional pieces of information on what is needed coming mostly from the users in the form of problem reports. I will describe the evolution of that code since its inception in 2013 and explain the reasons for making the changes in it.

Distributed Revision Control for Structured Data - Gavin Mendel-Gleason, TerminusDB
Revision control for source code - and especially Git - has caused a great leap forward in software development and delivery. A similar revolution has not yet taken place in data. This talk will discuss the various open source databases that are approaching this problem, the underlying architectures and challenges in building both a 'Git for data' and a 'GitHub for data'. It will posit that to be a truly collaboration and distributed system, it must be: 1) decentralized 2) offline-first: work offline and then resync when online again 3) reliable: conflicts are handled properly 4) private: end-to-end-encrypted, if desired 5) efficient: only changes (diffs) to the data set are transmitted between participants 6) collaborative: multiple people can work on the same data set Many applications choose the SaaS-route with one central database behind a web service and every frontend displays an instantaneous view of some part of the data set. This breaks most requirements. The database-as-a-service approach with a MVCC database & the flexibility to version schemas is a prerequisite for success. Finally the talk will look to the future and the dawn of CI/CD for data.

Tutorial: From an Idea to a Patch in the Linux Mainline - Marta Rybczynska, Various Projects
In the tutorial we're going to cover the basics of Linux kernel development, from the idea (or a bug found!) to the change integrated into the Linux mainline. We'll start from setting up the environment: the Linux kernel source, the compiler and debugger. Options like embedded debugger and using virtual machines in case of kernel crashes will be taken into account too. Then we'll cover the implementation of the patch, showing where to look for the information about APIs, how to correctly use the Linux coding style and write patch descriptions. The audience will also learn about the unit test mechanism and testing in the kernel in general. Then we're going to move to the process of getting the patch to the mainline: starting from where and how to send it. One of the scary points for new developers is the review process and we're going to demystify it. As a bonus, we'll show how to make maintainers happy and build a good opinion about you and your work. Pre-requirements: C coding, usage of Makefiles. No previous Linux kernel development experience necessary.

Confessions of a Late Bloomer: Overcoming Obstacles and Challenges as a Woman of Color - Jennifer Madriaga, Red Hat
Those of us who identify as members of underrepresented groups within the tech industry tend to enter this space via non-traditional routes. As a result, obstacles and challenges are not always immediately identifiable to those wanting to recruit and retain employees from underrepresented groups. Well-meaning allies can sometimes unintentionally undermine efforts related to diversity and inclusion because of their blind spots and unwillingness to own and deal with them. I'll share my story how I came to be in open source after years of not being in the work force, the fears and anxieties from imposter syndrome, the pitfalls that can happen when conversations on race and diversity become a new priority for teams and companies as well as address questions and potential strategies to address those pitfalls. The work around diversity and inclusion is one that requires commitment, honesty, and sometimes very painful acknowledgement and learning. While the work is difficult, it is very much necessary. We'll talk about guidelines around what can be done to move forward and how to set realistic expectations for change.

Cloud-Native App Development 101 - Avni Sharma, Red Hat
As the cloud becomes pervasive in IT, it then becomes increasingly important to adopt cloud-native technologies. For enterprises and vendors, building in the cloud is an opportunity to refresh applications and architectures in ways that make them more flexible, scalable and resilient.  Cloud Native technologies are used to develop applications built with services packaged in containers, deployed as microservices and managed on elastic infrastructure through agile DevOps processes and continuous delivery workflows. The session explains What is Cloud Native, Why, and How to adopt Cloud Native.  This session would shed light on Cloud Native technologies and containerization, moving from a monolithic based architecture to microservice architecture, and then implementing a demo where we build containers and also migrate it to a Kubernetes environment.

Sharing the Load Effectively: Roles and Responsibilities in Open Source Projects - Jeffrey Osier-Mixon, Linux Foundation
Success is almost always about setting & meeting expectations. This presentation details the standard roles within large-scale open source projects, and expectations associated with those roles. In addition, it covers best practices for community-led executive roles - board directors and officers, committee leaders, and others - as well as roles often contracted to foundations in order to stay neutral, such as executive director or program manager. Jefro will share experiences, revelations, and mistakes from over 10 years as an administrator and project leader, and as a technical contributor going back to the early days of open source. Open source projects are often a labor of love, and while it is tempting for many of us to step into gaps in order to fulfill the needs of a favorite project, it is possible to end up sprinting all the time. However, as the Zambian proverb says - When you run alone, you run fast; when you run together, you run far. It is more effective - and more in line with open source values - to share the load and go for the longer distance. (As a bonus, this also usually ends up being faster as well!)

Boot-Time Optimization for the Real World - Michael Olbrich, Pengutronix e.K.
There have been many talks about boot-time optimization in the past. For the most part, the only goal was a minimum boot-time. It's a good way to show the optimization techniques and gives a nice wow effect. But the end result is rarely usable in real world projects. So instead of looking for new ways to reduce the boot-time just a little bit more, this talk will look at boot-time optimization in a larger context. "The device needs to boot faster" is often stated but the actual requirements behind this are often more complex. We will look at typical requirements and possible solutions beyond general boot-time optimization. And while booting as fast as possible is nice, in most cases there are other more important requirements, which are often related to security or reliability. This talk will look at possible optimizations in this context. What are the consequences of an optimization and what trade-offs are possible? And last but not least, let's talk about the hardware. The choices made while designing a device can have a big impact on the boot-time. Therefore this talk will end with advices for hardware design criteria and component decisions to keep in mind to boot fast.

Do We Need an Industrial Grade Linux? - Lars Geyer-Blaumeiser, Bosch.IO
Bosch as well as many other industrial companies use GNU/Linux as an operating system for a large portion of the devices they produce in particular in the IoT context. While Linux distributions have done a great job to compile and maintain a consistent set of packages to provide the software stack for these devices it still requires huge extra efforts to fulfill the increasing requirements over the entire device life cycle that is currently done internally for each device class. As it is based on open source the question is if a significant part of this work could also be done in an open source way with all the positive effects that we can see in the community. There are first approaches already in the open, like Apertis (https://www.apertis.org/) or the CIP project (https://www.cip-project.org).

Solving the Twelve Year Old ftrace Time Stamp Puzzle - Steven Rostedt, VMware
Since 2008, the ftrace ring buffer inside the Linux kernel has been used to debug numerous issues. With recording events within nanoseconds, it's streamlined processing that keeps overhead very low, hard to debug areas of Linux can easily be traced. It works in all sorts of context including non-maskable-interrupts (NMIs), that makes it an ideal debugging tool. With its incorporated timestamp counter, it can show how long functions last, or time the latency between events.

But this timestamp had a flaw for all these years; It would not give time deltas for events recorded in a context that interrupted the recording of another event on the buffer. This issue has now been solved.

This talk will go over why it was so difficult to solve the nested event timestamp issue, and then a step by step dive into its solution. If you like to geek-out over hard to solve problems, and then see how they are eventually solved, you will enjoy watching this talk.

Distributed SQL vs Polyglot Persistence: Which Database Architecture for Cloud Native Microservices? - Karthik Ranganathan, Yugabyte Inc.
Microservices model and manage data with specific performance, availability and correctness needs. And they are increasingly deployed on Kubernetes-driven containerized infrastructure. There are two distinct architectural approaches for handling the database layer for such microservices. Polyglot persistence requires each data model to be powered by an independent database that is purpose-built for that model. Developers loved this approach because the traditional RDBMS lacked horizontal scalability and native resilience. End result was a proliferation of NoSQL databases. While developers had the best of intentions, operations became significantly complex with each database requiring its own operational runbook to be created prior to production rollout especially on newer environments managed by Kubernetes. Distributed SQL is an alternative approach where microservices exploit the native scalability, resilience and geo-distribution of a distributed RDBMS with SQL as the standard data modeling language. This session will explore the tradeoffs between the two approaches and highlight why distributed SQL is becoming a popular choice using an ecommerce application as an example.

Image Signal Processing (ISP) Drivers & How to Merge One Upstream - Helen Koike, Collabora
Image Signal Processing (ISP) units are hardware accelerators attached to camera sensors. Coming with more and more features, ISPs are essential nowadays for phones and tablet devices, capable of capturing pictures with high quality resolution and several image effects and filters.

The Media subsystem in the kernel offers a framework and defines APIs for ISP drivers to be upstreamed. There are different ways to model the hardware and expose its capabilities and features to userspace through a Media topology, which reflects the complexity of the hardware. Cameras are becoming more and more complex, making it necessary for drivers in userspace, and this is where the libcamera project comes into play.

In this talk, Helen will share a bit of her experience upstreaming the Rockchip ISP1 driver, going over the topics mentioned above, also comparing with other ISPs hardware/driver architectures and sharing tips and lessons learned along the way, to hopefully be useful for other willing to upstream another ISP driver.

Waylandifying Chromium - From Downstream to Shipping - Maksim Sisov, Igalia
Wayland is a protocol for communication between compositor and clients that is intended to fix long standing flaws of the X11 model. Its lightweight nature results in a significantly better performance in environments that are limited in resources. Since the demand for adding Wayland support to the Chromium browser is high, Igalia is sponsored to design, implement, and upstream that to the Chromium mainstream repository and verify the smoothness of the implementation. Igalia is also driving the effort to make official distribution of the Chrome browser support Wayland for Linux platforms so that users can simply download the browser and enjoy exceptionally good performance of their favourite browsing engine natively on Wayland. This talk will provide a history of the project, explain the idea behind Ozone component in the Chromium project, explore how the Wayland client implementation is designed in the Chromium browser, talk about limitations and design solutions we have had to come up with, compare the performance of Chromium running on X11 and Wayland on the RPi 3 Model B+ board, and close the talk telling the audience what we are currently doing to ship Wayland in Chrome.

Tutorial: Debugging Embedded Devices using GDB - Chris Simmonds, 2net Ltd
Bugs happen. Identifying and fixing them is part of the development process. This tutorial demonstrates one of the key tools in the embedded Linux developer’s toolbox: the GNU Debugger, GDB. You will begin by using GDB to debug a program running on a target device. You will learn about debug symbols: how build them into programs and libraries, and the places that GDB will go looking for them. Next, you will perform basic debugging tasks, including setting breakpoints, stepping through code, examining variables and modifying variables. After that you will lean about GDB command files and how they can help you by automating certain tasks. You will receive a handy GDB cribsheet to help you with all of this. If time allows, we will discuss how to use GDB to analyse core dumps so that you can perform a post-mortem on a crashed program.

Keynote: Open Source: Show Me the Money? - Liz Rice, Vice President, Open Source Engineering, Aqua Security
There is a lot of debate about how to make a business based on open source software, but what if you're coming from the perspective of a company that already has commercially successful, proprietary offerings? How can you persuade your sales team, your commercial leaders, and your investors that it will be good for business to start giving source code away for free? Why should a company invest engineering resources in other people's open source projects, when there is plenty of work to be done on your own products? In this talk, Liz will share the approach that Aqua Security has taken to embrace open source and make it a fundamental pillar of its overall strategy. She will share practical steps and learnings that could help you unlock the open source potential for your own business.

Can I Build an Embedded Linux System with Clang - Khem Raj, Comcast
GCC has been primary C/C++ compiler for Linux in general and embedded Linux in particular for long however LLVM/Clang has been gaining support for many architectures prevalent in embedded designs e.g. RISCV, ARM, MIPS to name a few, however there are challanges in porting software from one compiler to another and clang has been inching steadily towards building many system components, this talk therefore will go in detail on where clang based toolchains stand in building embedded linux systems, and discuss challanges e.g. kernel and other key pieces e.g. system C libraries which are specialised pieces of software and how to port them effectively, It will also cover the additional tools coming with clang which makes it easy to develop software and provide additional tools to developers. Clang has become primary compiler for many major applications e.g. chromium browser etc. so it will also cover these areas too

Panel Discussion Follow-up: Do We Need an Industrial Grade Linux? - Lars Geyer-Blaumeiser, Bosch.IO; Kate Stewart, The Linux Foundation; Jan Kiszka, Siemens AG; Guy Lunardi, Collabora Limited, & Andre Barkowski, Robert Bosch GmbH
Bosch as well as many other industrial companies use GNU/Linux as an operating system for a large portion of the devices they produce in particular in the IoT context. While Linux distributions have done a great job to compile and maintain a consistent set of packages to provide the software stack for these devices it still requires huge extra efforts to fulfil the increasing requirements over the entire device life cycle that is currently done internally for each device. As it is based on open source the question is if a significant part of this work could also be done in an open source way with all the positive effects that we can see in the community. There are first approaches already in the open, like Apertis (https://www.apertis.org/) or the CIP project (https://www.cip-project.org). In this panel, we want to discuss with partners from the industry and service companies about the need and possibilities of this approach and raise the question to the audience about their experiences and potential needs in this area and how we can together improve the situation for us all.

Giving and Getting Technical Help in Open Source Without Being Scared! - Sonia Singla, CNCF
As a developer, it’s exciting and challenging to stay up to speed with the latest trends in technology.Every day, new languages, frameworks and devices capture our attention and spur conversations in meetups, forums and chats.However, our developer community is made of people, not tools, and it’s fascinating to explore its sociopolitical aspects. We are always beginners at some things and experts at others.Along the way from beginner to expert we ask a lot of questions, but it can be intimidating to ask for help.This talk will be split into two halves: giving and then getting technical help.This talk gives concrete tools to help you ask with confidence, and highlights common expert mistakes that inadvertently make people feel foolish.It's important to learn how to manage your contributors in open-source.Once you learn it, your project will succeed and more contributors will flock to you!

M.V.G. – Minimum Viable Governance - Stephen Walli & Sarah Novotny, Microsoft
There is a proliferation of open source related non-profits, each working to drive attention to a set of projects or technology spaces, each demanding attention or membership dollars for growth. One of the first discussions such non-profits encounter is the governance discussion. Then come the projects for the non-profit to support, and each of them too wants to have a discussion about governance. We will look at the history of open source non-profits, and their governance structures, and how it met their goals (and the goals of their projects). Then we will look at what’s changed and work to evolve the model that people can use to judge for themselves whether a non-profit solves for the problems that need to be solved. Understanding the underlying governance models and structures in a non-profit will allow project owners and non-profit members to better judge what is needed for growth, what growth might look like, and what it will cost in effort and money. Sarah and Stephen have worked in a number of different open source project and non-profit settings and can speak to the models, mistakes, and learnings.

Creating Debian-Based Embedded Systems in the Cloud Using Debos - Christopher Obbard, Collabora Ltd.
Debian has traditionally been thought of by many as a desktop operating system but over the past few years significant effort has gone into enabling Debian to run on embedded targets. The result of this is system designers have a solid set of over 51,000 verified packages to choose from in their embedded system. In this talk Chris will describe the process of creating an embedded system derived from Debian packages in a few lines of YAML markup using an open-source tool called Debos: Debian OS builder. Pairing Debos with GitLab Chris will describe how Collabora are enabling manufacturers to automatically and securely deploy their new operating systems and custom packages nightly to developers for their upcoming system. Chris will share the complete back-story and steps to begin creating your own images. No previous experience of Debian or YAML is required for this talk.

Embedded Linux Systems in Smart Agriculture - Ronald Kipkirui Mutai, Burphurm Enterprises LTD, Kenya
Advancement in technology is a huge improvement that may be a panacea to our global challenges relating to climate change. Embedded technology is the way to go in such fields since the growth of IoT is in an upward surge. In Africa there are countries that have started such ventures and their outcomes are to be envied and emulated. This proposal is aimed at enhancing the use of embedded Linux systems in both animal and crop farming. There are few and shallow but adequate technological uses on farming in terms of inputs and selling of the farm produce for example Digifarm championed by one of the mobile telephone service providers in Kenya, there are also other apps that are used to link farmers to consumers and farm inputs. With this proposal data can be collected, accumulated and stored on cloud infrastructure for research and development as well as management, pest control and marketing of the farm produce to other consumers who are interested in the produce.

Fuzzing Linux Drivers with Syzkaller - Ricardo Cañuelo Navarro, Collabora
Fuzzing is a very valuable tool for software developers and maintainers, as it fits in an important part of the field of Software Testing that is not easy or viable to tackle with manually-written tests. A good fuzzing framework can automatically uncover many bugs that may otherwise only surface at runtime in a real-world scenario, and they are also a nice addition to a CI system. Syzkaller is a coverage-guided fuzzer that is being successfully used to find bugs in the Linux kernel. This talk shows a way to target it to specific drivers in dedicated hardware, reducing the search space and allowing for a more complete and focused code coverage.

Monitoring Linux Systems Using Kernel Audit Subsystem - Vandana Salve, Prasme Systems
Monitoring allows us to collect, store, and analyze the detailed information on the system at any given time.
Using the audit subsystem for monitoring these activities raises the level of security in Linux systems.
Although it doesn't offer additional security, it provides a detailed insight across the various critical kernel subsystems. With the help of detailed information on system activities and violations, it can be used to implement additional targeted security measures. The audit subsystem works by listening to the events reported by the kernel and logging them to a log file. In this talk, we will be taking a deeper look at the audit kernel subsystem and its use.

MySQL Performance for DevOps - Sveta Smirnova, Percona
MySQL performance can be improved by tuning queries, server options, and hardware. Traditionally it was an area of responsibility of three different roles: Development, DBA and System Administrators. Now DevOps handle these all. But there is a gap. Knowledge, gained by MySQL DBAs after years or focus on the single product is hard to gain when you focus on more than one. This is why I am doing this session. I will show minimal, but the most effective, set of options which will improve MySQL performance.

Handbook for Successful Online Open Source Sprints - Tania Allard, Microsoft & Cheuk Ting Ho, TerminusDB
Contribution sprints provide an excellent opportunity for project maintainers, users and aspiring contributors to work on open source projects. A common trend is to organise such sprints around other events such as developer conferences (i.e. PyCon). With most OSS projects being developed in a distributed way, in-person events bring together developers, designers and project contributors. Project maintainers often use these events as an opportunity to discuss the project roadmap or work on complex features as a team. The current worldwide panorama has changed our in-person interactions. As a consequence, most conferences have moved online, and with them events like contribution sprints. In this talk, we will present the many challenges we have faced when moving mentored contribution sprints to online formats. We will discuss how you can organise virtual sprints while preserving and enhancing the mentor and contributor experience - from technical to organisational and logistic choices. Finally, we will present the Mentored Sprints community handbook: a community-developed and oriented project aimed to support organisers, mentors and attendees of online contribution sprints.

Programming Extensions for Kubernetes and kubectl in Go - Philippe Martin, SFEIR
Kubernetes and its CLI kubectl are essentially written in the Go language. If you want to extend them by creating Kubernetes operators or kubectl plugins, you will need some knowledge on the client-go library, the Kubernetes API and the tools to create and test your solutions. Philippe will introduce the client-go library with some simple development and testing. Next, Philippe will present the KubeBuilder framework, one of the tools used to create Kubernetes operators, by demonstrating the development of a simple operator making easy the deployment of a series of static websites. Finally, Philippe will present the development of a kubectl plugin and its insertion in the krew index (krew is the kubectl plugin manager).

From Remote First Towards Async First - Isabel Drost-Fromm, Europace AG
Remote first - with current developments this is the new normal for many office workers globally. Often though this means replacing in person meetings with video calls - all to often leading to meeting fatigue. In this talk we will explore how open source projects have established different communication patterns. What is it that makes mailing lists so special for Apache Software Foundation projects and which properties would alternative technologies need to have to be a replacement? In which aspects does the use of issue trackers differ from your average agile project and what does that have to do with spring remote first collaboration? While likely basic to seasoned Open Source participants, these aspects are important to understand why they exist and how they are achieved to successfully communicate what makes both, InnerSource and Open Source projects work.

FOSS Static Analysis Tools for Embedded Systems and How to Use Them - Jan-Simon Möller, The Linux Foundation
Static Analysis becomes an increasingly important topic when the project involves Functional Safety aspects. This is the case in Automotive and in Automation as well.

One requirement to fulfill for functional safety is to prove the robustness and quality of the code used. Static Analysis can provide evidence for this early in development. This talk will show ways to include static analysis tools in your Yocto Project / OpenEmbedded based distribution.

Key elements of the talk are to introduce meta-sca as well as CodeScanner and meta-codechecker. With these tools it is possible to evaluate the code quality and increase it.

This helps the ecosystem to expand into new areas within the automotive and automation industry.

Getting a Time of Flight Camera Working in Linux, the Full Story from Kernel to User Space - Bogdan Togorean, Analog Devices
Video for Linux (v4l) is a well-established infrastructure for interfacing with video cameras, providing a comprehensive API for camera control and data acquisition. With the advent of the Time of Flight (TOF) cameras, outputting synchronized depth and IR images, there are a few challenges when writing kernel v4l drivers as well as user space applications since these cameras have different controls, more operating modes and, in many cases, different MIPI data formats and more virtual channels than traditional RGB cameras. This session talks about the implementation of the v4l driver for the Analog Devices ADDI9036 ToF processor, with an emphasis on the additional features that had to be implemented to expose the ToF camera's full functionality and on the changes that had to be made to get the same driver, or platform specific variants of it, working on different computing platforms such as Raspberry Pi, NXP i.MX8, Nvidia Xavier AGX or the Rockchip RK3399. It also introduces the user space software stack required to interface with the ToF camera, providing the full picture of the software components that are required to get a ToF camera working on embedded platforms running Linux.

Full Stack Debugging: From CI to ISS - Alexey Brodkin, Synopsys
Sometimes you find yourself looking at something a tiny bit incorrect, like your CI machinery reports a couple of more failures than you expect (surely you want zero failures). So you decide to fix it. You try to reproduce it outside the CI and... everything just works. OK, then you know who's guilty, right? That simple. And you ask your DevOps people to go fix their scripts. But apparently nothing helps, tests still fail in CI. And one fine day you decide to scratch that itch for real and start a journey down the rabbit hole. In this talk we'll reconstruct one very real debugging session which started from Zephyr RTOS tests failing in Jenkins-based CI flow and ended deep in the guts of the instruction set simulator (ISS). One by one we'll be inspecting possible faulty components (Jenkins, Shell & Python scripts used for test execution, Zephyr RTOS tests themselves and finally the simulator) until we may explain all the peculiarities observed before.

Efficient Syscall Emulation on Linux - Gabriel Krisman Bertazi, Collabora
New DRM and Anti-cheating techniques used in modern Windows games proved to be a limitation for the emulated environment provided by the Wine layer. In particular, these techniques force games to issue syscalls directly without going through the Wine-implemented winAPI, which means that for Linux users, these games escape the Wine sandbox and invoke the kernel with a broken ABI. Current kernel mechanisms to intercept syscalls like ptrace and seccomp are inefficient to solve these problems, since there is no way for applications to filter these syscalls and dispatch efficiently. This talk will present the new Syscall User Dispatch mechanism arriving in Linux 5.9, which introduces a new design for very efficient syscall filtering based on a userspace accessible key switch.

Open Source Mindset to Mindflex - How Flexing Perceptions of OSS Can Change the World - Clare Dillon, Mosslabs.io - Ireland
Clare is not a developer and is a relative newbie to the open source world. She made her first PR earlier this year. She got involved because she believes that open source is a way to construct alternative systems of innovation and remove some of the friction that is plaguing current efforts of "digital transformation". She has learned open source can help build trust, promote openness and collaboration, and provide alternative pathways to get involved with technology. It can help ensure that technology is not something that is built for people but instead built with people to help us digitally transform to a world we all actually want to live in. This is particularly relevant in the context of citizen services. Clare will share stories from her journey to be an open source advocate and how we still need to flex some perceptions and institutional constructs to help open source change the world.

Panel Discussion: Start the Girls Off Right: How You Can Help Get Girls Interested in Technology - Misty Decker, IBM; Kaitlyn Lowe, Brighton High School; Chloe Allen-Ede, University Student; Lella Halloum, Student & Z Ambassador
It's true that we need more girls to get interested in learning about technology. But did you know the same tactics that appeal to boys don't always work with girls. Did you know girls are more motivated by the purpose than by the tech? Or that girls usually decide they're "not technical" in middle school? Or that only 22% of girls can name a woman in tech? Or that fathers have a bigger impact on a girl's decision to pursue technology than mothers? In this session, you will hear from three young girls who are actively engaged in bringing tech to their peers and how you can use these methods to get girls interested in technology at all ages. You'll walk away armed with the tools to personally help in ways small and large. We're scheduled to present at an upcoming mainframe conference in the US called SHARE. The general topics will be the same but the examples will be mainframe oriented versus Open Source oriented for OSS. For example, one of the topics is to help girls "Do something Big - And Make Sure Everyone Sees it". For SHARE, we'll talk about participating in Master the Mainframe. For OSS, we'll talk about contributing to Open Source.

Debian and Yocto Project: a Tale of Two Distros (One of Which is Not a Distro) - Chris Simmonds, 2net Ltd
This is the choice: off-the-peg or bespoke. A mainstream distro such Debian can give you an instant, ready-to run system, great if you are using off-the-shelf hardware such as Raspberry Pi, or one of the Beagle Boards. Yocto Project, on the other hand, is the build tool you need to create a fully custom distro from scratch (you see, Yocto Project is not a distro, it *creates* distros) Each option has its advantages and disadvantages. There are a lot of things to consider. How much time and effort will it take to get my board up and running? How much storage will I need? How much control do I want to have over the software packages I deploy. How much effort do I want to devote to maintenance and security patches. All of these have an impact on the choice you will eventually make. This presentation will give you a roadmap that will help you decide.

From the Camera Sensor to the User, the Journey of a Video Frame - Maxime Chevallier, Bootlin
Video cameras are ubiquitous devices nowadays, taking a wild range of forms, from tiny sensors in your smartphone to complex cameras requiring lots of analog circuitry and internal decoding. The V4L2 susbsystem handles all of these devices, with an architecture capable of representing complex interconnections of components : Sensors, encoders, decoders, controllers, and so on. In this talk, we'll see how all of these components are chained together, using examples from real-life devices, by following the path of a frame, from the sensor up to the final consumer of the frame, which can be a display, a file on a storage, or a network stream. We'll see the various physical protocols and standards used for video transmission typically found on embedded systems, how they are implemented in the kernel and how to interact with them as a driver developer or a simple user. We'll also follow the transformations that a frame can go through so that it can in the end be correctly processed by the consumer. This talk's main audience are people who want to discover the various technologies around video capture, and that want an introduction to the complex but fascinating world of Video4Linux.

Gadgets and Trinkets, The Upstream Linux Way - Geert Uytterhoeven, Glider bv
The Arduino movement has popularized using micro-controllers to control simple low-speed devices like sensors and actuators. Hitting platform limitations, many people are stepping up to Linux systems. Affordable development boards capable of running Linux like Raspberry Pi and BeagleBone Black changed the scene, and joined people with an electronics and micro-controller background, and people from a traditional PC background, into a common community. Simple devices are typically connected to the system using serial busses like I2C, SPI, or UART, or even directly to General Purpose I/O pins. While the hardware side may be straight-forward, the software side became increasingly complex, and it is not always clear how to model your devices for use with Linux. In this presentation, targeting both makers and industrial automation, Geert will discuss your options for accessing such devices. He will cover topics like user-space versus kernel-space access, explain the why and how of Device Trees, and the desire for DT overlays, and identify gaps in current Linux support. All of this will be accompanied by examples, so attendees will be ready to apply this to their own projects.

Mix Edge and Electric Vehicles to Get a Shot at Sustainability - Diana Atanasova & Tsvetomir Stoyanov, VMware
Electric Grid Modernization involves comprehending renewable sources of energy, storage systems, actively monitoring power use, anticipating demand, and possibly shifting demand to smooth usage peaks. The last particularly helps to decarbonize the grid through avoiding the need to bring online dirty sources of energy to meet demand peaks. Electric Vehicle charging lends itself well to demand shifting. Perhaps you are at home and can delay charging for several hours or at work with enough charge to get back home, or just opportunisticly charging while shopping. Our solution leverages the open source project EdgeX Foundry to monitor and control one or more ChargePoint (CP) Charge stations. We invite you to explore our open source project Kinney, which provides Go and Python clients for CP's SOAP API and both a replay and full simulator (Covid-19 lockdown accelerated) We share alternative curtailment algorithms that take into consideration location, time of day, amount of vehicle charge, and charging patterns. Towards grid modernization the capturing contextual importance of various loads will help developing trade-off algorithms. Learn, experiment, drive sustainability!

A New Mount API - Christian Brauner, Canonical
Almost since its inception Linux had a single syscall for creating and changing mounts. It had to cover mounting of real filesystems, bind mounts, remounting to change superblock options, remounting to change mount-specific options, mount propagation and other filesystem specific options. This caused the syscall to be overloaded. The old syscalls also lacked desirable properties such as being able to apply mount options to a whole mount tree instead of just a single mount. The new mount api splits the single mount syscall into multiple syscalls effectively allowing to create a mount context that can be configured and interacted with before even making the mount visible in the filesystem hierarchy. In this talk we will cover the layout of the new mount api, how it can be used to replace the old mount api, and specifically focus on new features such as detached mounts, or mount notifications and why it is desirable for userspace to start switching to it rather sooner than later. We will also take the time to look at future extensions such as supervised mounts.

Telecommunication Industry is adopting the cloud native principles in 5G Evolution. This involves complexity in terms of orchestration,security and management. Service Mesh resolves these challenges by providing various operational,development and security benefits which are otherwise a nightmare for any developer to adopt into his application.
Telecom Operators have to make a careful choice of their unique implementation based on their requirements.
This talk will address the service mesh patterns that can be adopted towards complex Telecommunications Industry and it assumes that you have some familiarity with kubernetes and Service Mesh(Istio).

Lightning Talk: A Weather Balloon Example to Authenticate Data - Nicolas Lopez, Telokanda Remote Sensing Company
To address climate change and regional data collection issues in West Africa, we have begun a project of building weather balloons that cost well below typical radiosonde costs in the United States. Launching a weather balloon would reward local residents digital currency for their efforts, if the balloon was proven to reach a certain height. While pursuing this goal, we encountered some challenges that come from operating a business remotely. One of our obstacles was the need to develop a 2-factor authentication to ensure the owner of the device was indeed the same person using the web application. This is usually straightforward, but our application and network servers are owned and operated by multiple separate companies. Here we explore an authentication solution using blockchain that allows projects like these to become platform agnostic and able to be implemented when different companies own different parts of the data pipeline infrastructure.

Panel Discussion: Tangible Actions to Achieve DEI (Diversity, Equity, and Inclusion) in Corporations and Communities - Lisa-Marie Namphy, Dev Advocate & Community Architect; Lauren Maffeo, Steampunk; Joseph Sandoval. Adobe; Dimeji Onafuwa, Microsoft; Josu
Diversity is often used as a euphemism. An organization, company, or community can be diverse without being inclusive or equitable. However, diversity efforts without equitable practices and intentional inclusion will always fall short. The “tangible actions” are found in the “E.” Equity is an approach that ensures everyone access to the same opportunities to grow, contribute, and develop. It’s not enough to simply recognize that advantages and barriers exist. Equity acknowledges that unequal starting place and commits to correcting the imbalance. To get beyond euphemisms and onto tangible action we must understand what we are trying to achieve with DEI, why we care, what to do, and how to do it. These are universal problems and we will discuss globally-relevant solutions. This panel has experts in unconscious bias in data (AI), closing wage gaps, authors on D&I, corporate execs focused on diverse workforces and “the future of work," and community architects running some of the largest open source user groups. We were born in 4 different countries, and have lived and studied all over the world, with backgrounds from Africa, the Carribean, England, Mexico, and Native American.

Community Transformation - Enable Scalable Onboarding through Data Driven Initiatve - Sriram Ramkrishna, ITRenew Inc.
The GNOME Project to those not aware is an old project - from the late 90s. It grew up with a primarily engineering focus, an outdated development model, and a lack of structure. Despite that, the technology it has incubated is in widespread today. Growth is a problem - the continuing desire for resources is a common lament in large open source projects today. But the problem is more than just throwing developers at the problem. Scalable onboarding is a problem in its own right and it requires a deft touch. This talk will walk through the challenges of growing a project composed of many engineering teams, a media team, a documentation team, and a translation team with a host of skill sets not mentioned and the continuing work on the solution in development for over 6 months - methodology and ultimately implementation using the data built from the CHAOSS project on community health and aligning across each team dynamics.

What Differs the Android Open Source Project from Other Linux Distributions? - Sergio Prado, Toradex
Have you ever wondered what is running inside your Android device? Well, you know that you have a version of the Linux kernel there. But what about user-space? It is really a "different beast". If you log into an Android device, you won't find directories like /usr and /lib, or common init systems like systemd or sysvinit. X11, Wayland, dbus, glibc, the Android Open Source Project doesn't use any of that. For several reasons, Google decided to take the project in a different direction. What is the reason behind using bionic over glibc/uclibc/musl? Or Binder instead of D-Bus? In this presentation, let's have a deep look at the AOSP from the inside out and understand how this Linux based operating system really works.

Writing Your Own Kernel Cryptographic Accelerator Driver - Tero Kristo, Texas Instruments
Linux kernel crypto API provides ways to encrypt/decrypt data and to provide authentication info for the same. Some basic algorithms for this are gone over; hash algorithms for SHA1, SHA256, SHA512 and some basic cipher algorithms like AES / DES. Second part of the speak covers details how to implement a new cryptographic driver for one or more of these algorithms. In typical case this would be a new hardware accelerator driver for either a hash or cipher algorithm core. Driver level APIs required for these both are covered, in addition to the testing facilities provided by both kernel and userspace. In third part we go over performance and throughput measurements (openssl, tcrypt, IPSec), and how to optimize the driver to reach best possible results with these. Hardware vs. software cryptography performance is compared also with some TI SoCs used as reference platforms.

BoF: KernelCI: Lessons Learned - Guillaume Tucker, Collabora
A lot has happened since KernelCI was announced as a new Linux Foundation project at ELC-E 2019 in Lyon. One year on, what have we learnt?

We are witnessing an increasing number of individuals and organisations who are getting involved with the project and make it grow in some new ways. We now have much more build power, a fast-expanding functional testing coverage and a new database design to collate results from other existing kernel test systems. But what makes it truly special is how it has the potential to be driven by the kernel community at the same scale as the Linux kernel itself.

The KernelCI project team's main role is essentially to facilitate this to happen, by providing some technical solutions as well as an open forum for catalyzing progress in kernel automated testing and development workflows. Join the discussion in this BoF to take part in shaping another exciting year ahead! Key topics to get started include a follow-up from the community survey we did in June, what subsystem maintainers need in order to make KernelCI part of their workflow, how to run automated kernel tests in an effective way...

We'll be using a shared document to gather KernelCI Community Notes from the BoF discussions:

Open source communities have grown beyond what we can comprehend without tool support. The complexity is still on the rise including cross-community collaboration of dependent projects. We can use metrics for observing community health. This comes with challenges including a choice for what is important enough to measure and where to get the data. The birds of a feather session will begin by addressing the challenges with insights from the Linux Foundation CHAOSS (Community Health Analytics Open Source Software) project, which is at the forefront of establishing best practices for community metrics. These insights include: establishing a baseline against which to measure community changes, building a metrics strategy for a community, observing cross-community collaboration when contributors work across open source projects, and tools available to begin the metrics journey. After sharing these insights, the second part of the session will be an open dialog about experiences, concerns, and specific use cases that participants bring forward. For a large group, we will split into smaller discussion groups and share highlights at the end.

High Performance Node.js Powered by Rust and WebAssembly - Michael Yuan, Second State Inc
In the post Moore’s Law era, we need to squeeze more performance from existing hardware. Native code provides the best performance. However, the prevalence of native code on the server-side presents challenges to application safety and manageability. The advent of Rust and WebAssembly offers new ways for developers to write high performance yet safe Node.js applications. The Rust programming language is Stackoverflow’s most beloved programming language for the past 4 years. WebAssembly, on the other hand, provides a fast and lightweight virtual machine for running and managing Rust programs. Through open source bridges between Node.js and WebAssembly / Rust, we can now create JavaScript and Rust hybrid applications for Node.js, and shift computing loads to Rust functions. In this talk, I will go over the basics of Rust and WebAssembly, as well as their integration into Node.js. You will learn when and how to design a hybrid web application, how to code the high performance functions in Rust, and how to tie everything together in a Node.js JavaScript application.

Creating Community Messaging Strategy for Events and Beyond - Jennifer Madriaga, Red Hat
Are you part of an open source community, emerging or established, looking to participate in an event so you outreach to contributors and/or users, both current and net new? Are you struggling to find a voice or a balance with corporate stakeholders who want to prioritize product vs. technology messaging (to the detriment of community outreach)? Are you wondering how to create a messaging strategy that makes sense and benefits all stakeholders--community, the company, attendees? Events are a key part of strategy for open source communities as well as for many companies, trying to onboard contributors and users (including customers.) However open source communities must approach messaging with nuance and understanding, which can sometimes be a source of tension with those within corporate, product, and field marketing team, who may be several levels removed form daily open source participation. Learn how to navigate the maze of sometimes seemingly conflicting priorities and how to create a messaging strategy that can serve all interests, while respecting open source culture and communities.

Advanced Systemd for the Embedded Use-Case - Jeremy Rosen, Smile
When discussing systemd for embedded system, the discussion is usually limited to two aspects: * systemd boots faster * systemd is big. Though both points are valid, systemd brings much more to the table than an alternate method of booting and provides invaluable tools for the specific problems that embedded systems commonly face. This talk will list various features of systemd that deserve to be better known and that can greatly help embedded system development. Especially in the domains of security, reliability and reusability. Knowing the tools that systemd provide can greatly help the embedded engineer solve common integration problems and this talk's aim is to help embedded engineers know the tools that are available and the problems that have already been solved for them.

Graphical User Interface Using Flutter in Embedded Systems - Hidenori Matsubayashi, Sony
Sony has been researching open source Graphical User Interface (GUI) frameworks available for embedded products. There are many GUI frameworks in OSS, but there are some issues and trade-offs such as functionality, maintainability, compatibility with display manager (X11, Wayland), and software license. For example, in the case of consumer electronics products, higher designability is required. Furthermore, linking mobile apps and web apps and a development environment that facilitates development are required. Therefore, HTLM5/JavaScript using WebView (embedded browser) is often used. However, when using WebView, there are issues such as footprint and vulnerability countermeasure costs. Regarding Wayland, which is being mainly supported by Board Support Package (BSP) of SoC vendors, existing OSS sometimes lacks Wayland's support. And using it as is may cause stability problems. To solve above issues, we have adopted Flutter, which is a GUI framework for mobile and desktop in OSS, and developed to support Wayland protocol, application manager and development environment suitable for embedded systems. In this talk, we will talk about our challenge and exhibit demo applications.

ACRN Security: A Journey into Fuzzing and Hardening Edge Hypervisors - Mostafa Elsaid & Steffen Schulz, Intel
With the rise of data-centric IoT and Edge Compute, hypervisors have become a key component for real-time assurance, workload consolidation, and management. Unlike traditional cloud infrastructure, hypervisors at the Edge face an extended threat model with a broader set of threats and requirements (e.g. determinism, data privacy, etc..). As a result, ensuring the security and functional correctness of critical elements in the Trusted Computing Base (TCB) is crucial for the overall edge node security and dependability. Dynamic security validation methods like "Fuzzing" have been highly successful in uncovering novel bugs with runtime impact. However, as of now, there are no effective tools for covering the complex and diverse nature of components in the modern virtualization software stack. In this presentation, we discuss state-of-art fuzzing approaches that fit into the virtualized edge ecosystem. In addition, we share a set of Best Known Methods (BKMs) and techniques to execute a comprehensive fuzzing campaign for components scattered across different software layers; starting from the hypervisor, kernel service modules, and up to the Device Model (DM) in userspace.

BPF Tales, or Why Did I Recompile the Kernel to Average Some Numbers? - Giulia Frascaria, Vrije Universiteit Amsterdam
“eBPF should stand for something meaningful, like Virtual Kernel Instruction Set”, says Brendan Gregg. Well we took that statement seriously, and had to put it to the test! Looking at current use cases we saw that eBPF can be used to filter and modify in-flight data for the networking stack, so we thought “why not storage?”, given the whole literature of work trying to reduce the size of data transfers. You know, end of Moore’s Law, blazing-fast new storage that outperforms CPU throughput, Big Data all over the place… Wouldn’t it be great if we could filter it with eBPF? Yes. Is it easy? Join the talk to find out (spoiler, not yet). In this talk we’ll stress-test eBPF, and see how it is tamed by the (very unforgiving) verifier, making it hard to even average a few numbers. Expect to hear about some kernel headaches.

The ELISA Project: Enabling Linux in Safety Applications - Lukas Bulwahn, BMW
There is a current industry trend to build fully autonomous systems. To reach this goal, industry must manage complex software systems with high performance, safety and security requirements. The operating system is non-differentiating in these systems and it is intended to be used multiple times over the whole product portfolio for a long time span. These conditions make it appealing to use Linux as a robust open-source operating system. Based on the results of the SIL2LinuxMP project, the Linux Foundation has initiated the ELISA (Enabling Linux In Safety Applications) Project in the beginning of 2019. The talk shall sketch goals of this collaboration, the first identified challenges of addressing safety aspects in the Linux kernel and the plan how to tackle them. Now, one and half years in movement, we can report our first steps and discussion results, go much more into the detailed problems we face and share our insights based on our recent retrospective. These pointers on challenges are generally insightful for any open-source project that wants to argue its quality and management of quality, as well as for companies that would like to develop their products with these insig

From the Ground Up: How We Built the Nanos Unikernel - Will Jhun, NanoVMs, Inc.
A concept that has been kicking around in systems research for a few decades, the unikernel presents a compelling foundation for services in a modern context, both within the cloud and at the edge. Unikernels promise sub-second boot times, small footprints, small attack surfaces and a huge number of VMs per host, all highly desirable attributes for single application deployments in a virtualized environment. This talk will present Nanos, a new, open-source unikernel that runs a wide array of real-world applications. Nanos is lightweight (~1/2 MB kernel text and data), runs Linux ELF binaries (typically without patching or modification) and employs standard protections such as split kernel / user memory, page protections and ASLR. The talk will open with a practical walk-through, presenting the process of staging a Nanos unikernel, running it on a local hypervisor and deploying it on a cloud platform. The second part of the talk will discuss the development process and techniques atypical in a kernel environment, including type introspection, a tuple data store for configuration and metadata, and the use of closures (in C) to compose concurrent, asynchronous operations.

How Non-Violent Communication Can Help Keep the Peace on Your Team - Casie Siekman, Prime Digital Academy
Non-violent communication will help you communicate with your coworkers in a manner that enables productivity and helps you understand how their unmet needs might lead to negative interactions. Successful communication is a huge part of a project’s success – everyone on the team can benefit from NVC. Non-violent Communication is based on the idea that all human beings have the capacity for compassion and only resort to violence or behavior that harms others when they don’t recognize more effective strategies for meeting their needs. Especially in our technological industry, there are many chances for miscommunication which can lead to all parties feeling dissatisfied. Unspoken expectations, ignored feelings, and accusatory or aggressive language can bring an otherwise productive team to a halt. This presentation will show you how to be aware of yourself, how your actions affect others, and how to deal with and understand others that may be negatively affecting you. I have given this talk before, and it evolves every single time based on feedback, and the lessons I continually learned while applying these concepts to my work and personal life.

LoRa/LoRaWAN in Zephyr - Manivannan Sadhasivam, Linaro
The Eclipse IoT Developer Survey 2019 showed that Zephyr had approximately 3% of the RTOS market share for IoT. And so the number should've increased by now. Zephyr is becoming the de facto Opensource RTOS for the IoT market due to its scalable and yet feature-rich nature. Zephyr already supports multiple SoC architectures and communication protocols. But for Zephyr to become an RTOS for Industrial and Smart city applications, it needs to support a communication technology that can transmit data at longer distances in a less congested spectrum. This is where LoRa (Long Range) communication technology by Semtech perfectly fits in. The basic LoRa support in Zephyr was added back in December 2019 and since then there has been a huge interest among the community to extend the support for it. More recently, the LoRaWAN support is also added to Zephyr. This will provide true networking support to Zephyr over LoRa. This talk will briefly go over the current LoRa/LoRaWAN support in Zephyr, the motivation, future plans, etc...

Getting to Know Spectre & Meltdown Checker - Agata Gruza, Intel & Stéphane Lesimple, OVHcloud
Spectre & Meltdown Checker is a widely used open source hardware vulnerability checker tool. This simple to use application evaluates your system’s exposure to speculative execution side channel issues and detects the presence of security mitigations on your system. It is compatible with BSD and all Linux* flavors and distributions, and can be used on-premises, in virtual environments, and in containers.

In this session we'll take a trip back to early 2018, when Spectre & Meltdown changed the landscape of the IT security for years to come, which made this Spectre & Meltdown Checker a necessity. You will learn the process of contributing to Spectre & Meltdown Checker (what needs to be done between discovering a CVE vulnerability and pushing a patch to address the CVE to the public main repo). We will go over CVE nomenclature for new CPU vulnerabilities, creating a list of unaffected processors, new hardware capabilities, and the patch itself. From there Agata will cover steps on how to install the checker script, and then how to review and read the output from the tool. She will wrap up with what to do if you discover a vulnerability in your system.

Virtualization for Real-time Power Grid Substation Automation - Lucian Balea & Aurelien Watare, RTE
Energy Transition drives change in power transmission and distribution grids. Grid control architectures should adapt swiftly to manage more distributed renewable infeed and greater dynamics in power flows. In this context, grid operators require a new generation of digital automation system for power substations, enabling higher flexibility, scalability, cross-industry innovation while ensuring time and cost-efficiency. Following the path of other sectors such as telecommunication networks, open source and virtualization will be the mainstays of this new systems. In the first half of 2020, a Design Team was formed under LF Energy umbrella to draft the roadmap of an open source project aiming at developing a “reference design” and “industrial grade” platform that can run virtualized real-time automation applications. This group gathered several technology vendors and end-users. This session will present the works of the Design Team, touching upon the system architecture and technology stack implemented in the project (Yocto, KVM, OvS, DPDK, Docker, Kubernetes). It will also outline the specific requirements of the power grid industry and the next challenges of the project.

Challenges of Using V4L2 to Capture and Process Video Sensor Images - Eugen Hristev, Microchip Technology, Inc.
The Video4Linux2(v4l2) is a complex subsystem in Linux that offers great capabilities for configuring a complete video capture pipeline. This presentation focuses on the challenges of taking a photo with a digital sensor, that in most cases is not adapted to the ambient scenery, and how dedicated hardware and software can help the simple photographer to take the best quality photo that they can. A hardware and software pipeline starts from the basic raw pixel data that comes from the sensor, and it goes through several processing stages, from interpolation of raw BAYER matrix and color space conversion to RGB space, color correction, brightness and contrast adjustment, white balance algorithms to adjust to ambient light, and in the end converting to a user friendly image format type. The presentation allows a non-experienced photographer, or a photographer used to classic cameras, to understand the difficulties of digital photography, and how Linux, and especially v4l2, can control, adjust, and automatically perform tasks that will help anyone take photos easy, with minimum amount of effort. The end goal is to understand the functionality of an Embedded Linux Camera.

Since first introduction of linux/clk.h in 2006 from Russel King, clock management was progressively part of the needed system management and resource handling in drivers. Then, in 2012, Mike Turquette introduced the "Common Clock Framework" he co-maintained with Steven Boyd, becoming a central "Framework" handling clocks over the system to provide controls by the device drivers. However, what are these clocks? What are they in physical terms? How are they modeled in Hardware? Why do we need them to control internal&external devices?

Microservices 1.0 was an organizational breakthrough that led to higher velocity and easier scaling for development teams. It caused negative side-effects of service dependencies and data sprawl, which damage SLO performance and make data features complex to build and maintain.  Microservices 2.0 uses a service mesh and a data mesh to retain the positive velocity and scaling attributes of microservices while constraining the negative side-effects.  These meshes enable creation of data economies, where there is a free and open market for microservices that shape the data.  Data scientists, developers, and product owners can find and share the microservices that work best for them, while all access common data.

Building Embedded Debian and Ubuntu Systems with ELBE - Köry Maincent, Bootlin
One of the traditional approach to build custom Linux systems for embedded devices is to use build systems such as Yocto/OpenEmbedded or Buildroot. In some cases, using a more conventional binary distribution such as Debian or Ubuntu has interesting benefits: powerful package management system, a wide selection of available packages, no need to learn a new build system, excellent security updates, and more. However, Debian or Ubuntu themselves don't really come with appropriate tooling to easily generate ready-to-use filesystem images. This talk will therefore present ELBE, an open-source tool that generates, based on a description file, a complete Debian or Ubuntu filesystem image, cross-compiles additional packages if needed, adjust the filesystem contents, etc. We will start by comparing the different approaches to build an embedded Linux system, what is the approach taken by ELBE, how it can be used to generate systems for ARM and ARM64 targets, but also how we extended it to support generating Ubuntu-based systems in addition to Debian ones.

Keynote: Operationalizing a Global, Circular IT Industry is Both Our Opportunity and Imperative - Ali Fenn, President, ITRenew
The global IT industry is responsible for 4% of global emissions and on track to double by 2025.  In the data center world, we are collectively doing a decent job driving advances in operational energy efficiency.  But this is only part of the puzzle, one-third of the puzzle in fact.  To truly assess and address the environmental impact of data center equipment, it is imperative to include both pre-use (embodied) and post-EOL costs of the massive scaling of our collective infrastructure.  In this session, we will explore the true total cost of equipment, and the opportunity represented by circular data centers to redefine lifetimes, and maximize both financial value and sustainability.  Operationalizing circular data centers means enabling a global, circular IT hardware industry, and to do so catalyzes both financial and environmental opportunity, and democratized access to growth.   We’ll talk about what this entails, the role of open hardware, what’s happening now, and what is at stake.

Why the GPL is Great for Business - Frank Karlitschek, Nextcloud
In the last few years we saw a lot of discussion in the open source and free software startup space around licenses. Several companies stepped forward and claimed that it’s not possible to build a working company on top of a free software product. Some changed the license of their product to proprietary license like the Commons Clause or the Business Source License. They claim that this is needed to ‘save’ free software. This talk describes why this is fundamentally wrong. It’s possible to build a working startup and company on top of a free software product. This talk discusses how companies like Red Hat, SUSE and Nextcloud manages to have a 100% free software product including a big contributor community but is still able to pay developers and grow.

Linux on RISC-V with Open Hardware - Drew Fustini, BeagleBoard.org Foundation
Want to run Linux on open hardware? This talk will explore how the RISC-V, an open instruction set (ISA), and open source FPGA tools can be leveraged to achieve that goal. I will explain how myself and others at Hackaday Supercon teamed up to get Linux running on a RISC-V soft-core in the ECP5 FPGA on the conference badge. I will introduce Migen, LiteX and Vexriscv, and explain how they enabled us to quickly implement an SoC in the FPGA capable of running Linux. I will also explore other Linux-capable open source RISC-V implementations, and how some are being used in industry. I will highlight that OpenHW Group has adopted the PULP Ariane from ETH Zurich for its Core-V CVA64 implementation. Finally, I will look at what Linux-capable "hard" RISC-V SoC's currently exist, and what is on the horizon for 2020 and 2021. This talk is should be relevant to people who are interested in building open hardware systems capable of running Linux. It should also be useful to people who are curious about RISC-V. Software engineers may find it exciting to learn how Python can be used to for chip-level design with Migen and LiteX, and simplify building a System-on-Chip (SoC) for an FPGA.

Using the TPM - It's Not Rocket Science (Anymore) - Johannes Holland & Peter Huewe, Infineon Technologies AG
Nowadays, virtually all consumer PCs/laptops contain a TPM2.0 security chip, the Trusted Platform Module. Moreover, the TPM finds its way into more and more modern embedded devices. But what is the TPM and how can we use it on Linux? The TPM has the potential to enhance security in a variety of use cases ranging from SSH, VPN, disk encryption, and more. Since it is so powerful, it may be hard to use at times. But do not fret - the tpm2-software project, especially its new TPM Software Stack (TSS) Feature API (FAPI) library, enables anyone to use the TPM. This talk gives an introduction on how to use the TPM the easy way, using recent contributions to the TPM ecosystem like the TSS FAPI. After a brief overview of the involved hard- and software, this talk will dive into how to get started with the TPM and show how it can be used to perform fundamental security tasks. Afterwards, recent additions like the TPM PKCS11 middleware and the OpenSSL engine will be presented - enabling TPM integration, perhaps without writing a single line of code. In the end, the TPM open source ecosystem will be discussed, and how to become part of it. Want to start hacking? We got you.

Rootless Containers from Scratch - Liz Rice, Aqua Security
Containers have taken off as one of the foundational technologies that enabled cloud native application development and deployment. But despite their widespread adoption through Docker, Kubernetes and other tools, there has been a significant security risk: users have effectively needed root privileges in order to run containers on a host. Recently there have been significant advances to enable “rootless containers” - containers that can be run without requiring root privileges. This talk will use live-coding in Go to illustrate how rootless containers are created, exploring why root was originally required and what has changed to enable rootless operation. This talk assumes that you have some familiarity with how containers are built using namespaces, cgroups and chroot.

Demystifying Open Source Crash Reporter: An In-depth Security Analysis - Seong-Joong Kim, National Security Research Institute
Software vendors provide crash reporter to automatically collect crash reports from users to facilitate efficient handling of crash of their products. The crash reporter should be secure and reliable due to the fact that it handles sensitive information, such as core dump that captures the CPU context and memory contents of the crashed program, and helps to address the issue of crashed program. Unfortunately, several security flaws have been reported to the various crashing reporter for Windows, Mac OS X, Linux, Mozilla, etc. In this talk, Seong-Joong Kim will address security problems that reside in popular open source project for crash reporter. After auditing the source code, he found several flaws in the project, caused by unrestricted file upload vulnerability. When it allows the upload of an arbitrary crash report and the attacker may overflow a buffer on heap-memory, unhandled exception or cause resource exhaustion, which may lead to dreadful consequences. He will demonstrate those attacks and share the steps for improving security of the crash reporter.

Tutorial: Firewalls with NFtables - John Hawley, VMware
Linux networking has gone through many changes over the years, and the ip filtering subsystem is no different. From ipchains, to iptables, and now to nftables, which is quickly becoming the defacto standard for network filtering on Linux. This talk is intended to get users who have a basic understanding of networking an overview of nftables, why it's a major step forward, why it's taken so long, and to get attendees the basics (including examples) they can take to deploy their own network filtering using nftables. This is primarily targeted as a teaching and 101 level discussion, and to give attendees a starting point to go further from.

Tutorial: Running Your Own VM & Container Cluster at Home - Stephane Graber & Christian Brauner, Canonical Ltd.
LXD is an easy to use system container and virtual machine manager. On top of letting you create and run containers and virtual machines on a wide selection of storage and network options as well as featuring a modern REST API for remote management, it can also be very easily clustered. In this tutorial, we'll go over setting up LXD from scratch on 3 Raspberry Pi 4 and then configure it to allow remote systems to create and manage containers and virtual machines on those. Such a setup can be interacted with easily from the built-in command line tool available for Linux, macOS and Windows and can be shared with multiple users by using independent "projects" on that cluster. We'll also go over the most common web interface option to make it even easier to manage from any system on the network. This kind of setup can easily be replicated in the cloud or on any spare physical hardware and on the majority of hardware architectures. The Raspberry Pi 4 used in this case allows for someone to set such a redundant cluster for themselves at a very reasonable cost, making it a perfect way to experiment.

Lightning Talk: From PaaS to FaaS : Managing Serverless on Kubernetes - Suman Chakraborty, SAP Labs, India
Call it “serverless,” call it “event-driven compute” or call it “functions as a service (FaaS),” the idea is the same, allocate memory dynamically to event-driven functions to built microservices. Serverless computing platform allow developers to focus in building the application logic while abstracting away the infrastructure requirements and management details.

Many serverless offering from cloud-managed providers restrict the behavior of app logic that they run, sometimes making certain classes of applications impractical. Kubernetes has been the de-facto open source management platform for running applications in containers through a well-orchestrated tooling mechanism, taking care of the scalability, rolling updates, self-healing and load-balancing processes.
In this context, Suman Chakraborty will explain the major advantages Kubernetes provides in running serverless frameworks, the major open source projects that brings serverless functionality in Kubernetes and the challenges that has been reported by consumers in adopting Serverless frameworks in recent times.

Prometheus Enabled AI Deep Observability Based on eBPF - Ivy He, Huawei Technologies Co, LTD
AI training process is complex and invisible, when running the task, there are some monitoring blind spots by using the traditional tracing tools, which brings many difficulties to the developers to debug and tuning. For this reason, we choose eBPF to analyze the changes what we want to know in the real-time, such as: to understand whether a specific kernel function is called, short-lifetime processes, etc. With the data collected dynamically by eBPF, we choose the Prometheus to monitor and show them to the developers. In this topic, I will share the practice of eBPF in the observability of AI kernel. While running the AI training and reasoning tasks, we can dynamically inject the eBPF code into the kernel function to collect data, and report the data to the Prometheus in a unified format for visual management. The practice of the observability is currently in the experimental stage.

Knative: A Kubernetes Framework to Manage Serverless Workloads - Nikhil Barthwal, Google
Knative is a Kubernetes-based platform to build, deploy, and manage modern serverless workloads. It provides a set of middleware components that are essential to build modern, source-centric, and container-based applications that can run anywhere: on-premises, in the cloud, or even in a third-party data center. Knative components are built on Kubernetes and codify the best practices shared by successful real-world Kubernetes-based frameworks. Knative components focus on solving many mundane but difficult tasks such as deploying a container, orchestrating source-to-URL workflows on Kubernetes, routing and managing traffic with blue/green deployment, automatic scaling and sizing workloads based on demand, and binding running services to eventing ecosystems. This talk explains how Knative enables you to focus just on writing interesting code without worrying about the boring but difficult parts of building, deploying, and managing an application. It shows how developers can even use familiar idioms, languages, and frameworks to deploy any workload: functions, applications, or containers.

VM Forking & Hypervisor-Based Fuzzing with Xen - Tamas K Lengyel, Intel Corporation
In this talk we'll discuss Xen's new VM forking feature and the memory sharing subsystem it uses to achieve lightning-speed VM deployment. Forking a VM lends itself for use-cases where short-lived but identical VMs are useful, such as fuzzing. Using a hypervisor for fuzzing allows us to poke at code-locations that normally would be difficult or slow to fuzz, like the operating system itself. Without having to reboot the VM to recover it after a crash, fuzzing of the kernel and kernel modules can be achieved at great speed. We'll walk through the integration and harnessing required to start fuzzing a Linux kernel module using AFL on Xen. We'll further discuss other potential applications that are now achievable by combining Xen's VMI capability with VM forks. The presentation has been previously given at Xen Project Developer Summit 2020. This version of the talk will focus less on the hypervisor implementation details and more on the application of the system to fuzz various targets, such as system calls, kernel internal interfaces and even user-space applications.

Board Farm APIs for Automated Testing of Embedded Linux - Tim Bird, Sony & Harish Bansal, Timesys
For years, designers of automated testing systems have used ad-hoc designs for the interfaces between a test, the test framework and board farm software, and the device under test. This has resulted in a situation where hardware tests cannot be reused from one lab to another. This talk presents a proposal for a standard API between automated tests and board farm management software. The idea is to allow a test to query the farm about available bus connections, attached hardware and monitors, and other test installation infrastructure. The test can then allocate and use that hardware, in a lab-independent fashion. The proposal calls for a dual REST/command-line API, with support for discovery, control and operation - of hardware and network resources. It is hoped that establishing a standard in this area will allow for the creation of an ecosystem of shareable hardware tests and board farm software.

Using Raspberry Pi With Connected Analog as Lab Instrumentation - Mark Thoren & Brandon Bushey, Analog Devices
Laboratory instrumentation - voltmeters, oscilloscopes or GHz network analyzers - have evolved from purely analog boxes (1970s), to incorporating digital control with rudimentary connectivity (1980s), to embedded systems (1990s), and finally, to fully connected machines running desktop operating systems, greatly simplifying automation tasks, and the (finally) simple task of getting a data file onto another machine for deeper data analysis. In this session, we will review how a number common tools like the Raspberrry Pi and the Linux kernel’s Industrial Input Output (IIO) framework can be leveraged with directly connected Analog I/O to speed up the development process, whether the end goal is performing a one-off experiment, inclusion in production automated test equipment, or prototyping designs for standalone benchtop instruments. Examples to be covered include: 1. A DC to 6GHz, low-distortion, RF signal source 2. A 24-bit, ultra-precise DC measurement system 3. A precision voltage source with 1 part per million linearity.

OP-TEE is Ready: Let's Use It! - Rouven Czerwinski, Pengutronix e.K.
OP-TEE for i.MX6 SoCs is production ready, so we finally have a fully mainline way to use TrustZone on a widely available platform. So what are the scenarios where we it can increase security or allow new features? This talk will present the current state of OP-TEE from an upstream perspective on i.MX6 SoCs and show two different Trusted Applications (TAs) which provide secure data storage or TPM functionality. One of the presented applications will be the PKCS#11 TA which is currently being upstreamed into the mainline OP-TEE project. In conjunction with the OpenSSL PKCS#11 engine, it can be used to store client certificate data which can not be extracted from the device. The other application will be the Microsoft firmware TPM, which is provided as an out-of-tree TA with an upstream Linux kernel driver. It is meant as a replacement for conventional hardware TPMs and provides a tighter coupling to the chosen SoC. Furthermore this talk will highlight the necessary steps to actually secure OP-TEE on your chosen SoC, using the i.MX6 platform as an example.

Optimizing and Developing Non-CPU Device Power Management by DEVFREQ - Chanwoo Choi, Samsung Electronics
Power Management is necessary for embedded devices because of the limited power capacity. Kernel provides DEVFREQ (Device Frequency) framework to optimize the power management for Non-CPU devices such as GPU, memory bus, storage and so on. The market requires high-quality image generated by GPU and data transfer via memory bus quickly and low latency for accessing the storage. In result, the power is more used than before. The power management for Non-CPU device is mandatory on embedded device. DEVFREQ provides the multiple governors for supporting DVFS and allows user to add their own governor instead of using default governors. But, DVFS feature is not enough to meet the performance demands. It supports PM_QOS interface to set the min/max requirements by user and collaborates with interconnect framework in order to guarantee the min/max bus bandwidth. Also, it is connected with thermal subsystem to protect overheat of device. Like this, DEVFREQ provides the power-management mechanism and the extensible flexibility to user. In this session, explain how to optimize the power management with DEVFREQ and how to develop DEVFREQ driver.

The Fall of the Legacy - Vaibhav Gupta, Open Source Contributor
Power Management has always been a focal point in Linux, and along with PCI, it is like talking about fascinating powers subtle to handle. Among many ingredients of the magical PCI PM, PCI Core is a special one. The legacy framework provided good interaction between the Core and drivers, but a few years back, we came up with a generic approach that gave more control to the Core and made it possible for drivers to support PM without PCI helper functions. Vaibhav will discuss the simplification achieved after those unnecessary helper functions and the legacy support got removed as part of his project under the Linux Kernel Mentorship Program. He will talk about how this shift to the adoption of generic PM affects the performance and stability of PCI core functioning underneath. He will also discuss and share the work involved in converting drivers from legacy while balancing performance and stability along with changes to individual PCI drivers. You will come away with good knowledge of PCI PM and great respect for the community which has made it as performant as ever.

When You Come to a Fork in the Road, Take It: Finding Configuration Constraints from Kconfig, Kbuild, and the C Preprocessor - Paul Gazzillo, University of Central Florida
The Linux kernel source has thousands of compile-time configurations that allow for an enormous number of variations of the kernel binary. This extreme configurability enables the same codebase to be used for everything from refrigerators to cars to supercomputers. But such configurability also brings unique challenges to development and maintenance. Unexpected combinations of configuration options can expose unknown security holes, the sheer number of kernel variations makes testing all impossible, and the languages used to implement configurability hinder source-code tools such as IDEs, bug-finders, and refactoring tools. This talk will go over the challenges of scaling to Linux's massive configuration system and my research on using program analysis techniques and automated tools to extract configuration constraints from Kconfig, Kbuild, and the C preprocessor. I will demonstrate a free and open-source tool, klocalizer, resulting from this research. Given source files, klocalizer generates valid Kconfig kernel configurations that include the given source. Finally, I will go over future work and potential applications to testing, bug-finding, and security.

Unsolved Problems in Open Source Security - Rhys Arkins, WhiteSource
Very few people today doubt the principles and benefits of Open Source, but you can definitely be forgiven for having concerns about its security. Some of the ways we rely on Open Source today are fundamentally flawed, yet almost never discussed - from registries hosting unsigned artifacts of unreproducible source to package managers which propagate new versions of dependencies at the earliest opportunity. It's time to identify these unsolved - and mostly undiscussed - risks, evaluate their potential impact, and determine what can be done in the Open Source community to address them. This presentation will discuss why we need reproducible builds in open source, verified artifacts, and why the majority of package managers may need a substantial change, while one in particular got it right. It will also provide some recommendations on defensive use of open source particularly for products and industries at the highest risk of software supply chain attacks.

Tutorial: How to Ansible - John Hawley, VMware
Gone are the days when an administrator could, realistically, count the number of machines they were responsible for, and the days of very large scale deployments are here. This also means gone are the days when an admin could reasonably log into all of those machines to do the configuration by hand. Today it's best to rely on an automation framework to do this on a larger, more replicable, scale. Ansible is one such automation framework and this is a intended to walk folks through the very basics of Ansible, getting it set up, up and running, passing data, fetching information and generally getting comfortable with the basics of what configuration management is.

Tutorial: Understanding What Happens Inside Kubernetes Clusters Using BPF Tools - Alban Crequy & Margarita Manterola Rivero, Kinvolk
Kubernetes provides a high-level abstraction layer that makes it easy to deploy distributed computing resources without knowing what’s happening in the kernel and applications. This is great when things work as expected, but when trying to root cause an issue, Kubernetes does not provide any help in inspecting these low-level details.

During this tutorial, we’ll look into how using tools based on eBPF functionality can help us better understand what’s going on inside our cluster. We’ll check out two tools that were specifically designed to run inside Kubernetes:
* Inspektor Gadget, which includes a few innovative gadgets as well as easy-to-use wrappers around BPF Compiler Collection (BCC)
* kubectl-trace, which allows to use the power of bpftrace on Kubernetes clusters

Using these tools, DevOps teams can answer debugging questions such as:
* What were the last system calls executed before the crash?
* What network policies do I need to apply in my cluster?
* What executables are being run on my cluster?
* What processes are reading to or writing to disk?

This is an interactive tutorial. To follow along, you'll need access to a test Kubernetes cluster. For simplicity, we recommend running a specific Minikube version, but other options are possible. Please check out the instructions at https://github.com/kinvolk/cloud-native-bpf-workshop in advance. This will help you make the most out of the workshop.

Building Trustworthy AI: Lessons from Open Source - Abigail Cabunoc Mayes, Mozilla
Algorithms influence our lives: they decide what videos we watch next, and whether someone is eligible for parole. Yet every day, we hear new stories on how AI discriminates and amplifies bias. How can we build AI that is worthy of our trust? The free software movement was founded on principles protecting user rights (to use, modify, and distribute software). Through mechanisms like open source licenses, transparency, and collaboration, open source thrived and transformed our digital world. AI is at a similar crossroad – staged to change the digital landscape, but limited by questions of ethics and user rights. We have an opportunity to take lessons from open source to protect our rights while innovating towards an AI revolution. --- This session has not been presented before, however I will be presenting a version at COSCUP 2020 (Taiwan, Aug 2020).

Enabling Dissent for Better Open Decision Making - Sim Zacks, Red Hat
The open decision making process is so successful by empowering everyone involved to participate, provide feedback and influence the decisions. This is critical for understanding issues, gaining additional perspectives and making sure that the decision makers see all sides of the issue. However, for this to be successful, you also need to hear dissenting viewpoints. Enabling dissent is a very challenging aspect as not everyone with an opinion wants to be part of a debate. An open discussion does not always ensure that all voices are heard, and does not necessarily give the appropriate weight to a differing opinion. Attendees will learn about: * using open decision making and why dissent is such an important aspect * some of the reasons that dissent is often not heard * how to encourage and enable participants to voice dissent * structuring the decision making process so that there is more opportunity for dissenting *

Precision Time Protocol (PTP) and Packet Timestamping in Linux - Antoine Tenart, Bootlin
Time synchronization is important when dealing with transactions, transmissions, logging, etc. on multiple machines and high accuracy can be required. The precision time protocol (IEEE 1588) aims at providing a clock synchronization protocol with an accuracy down to the sub-microsecond range. In this talk we'll see how the protocol works, what are its modes of operations (1-step, 2-step, grand master, etc.) and see what capabilities of the kernel are used, such as packet timestamping. We will also cover how and why timestamping can be offloaded to hardware devices (MAC, PHY, switches), in particular for PTP packets.

RunX: Deploy RTOSes and Baremetal Apps as Containers - Stefano Stabellini & Bruce Ashfield, Xilinx
Containers are incredibly convenient to package applications and deploy them quickly across the data center. This talk will introduce RunX, a new project under LF Edge that aims at bringing containers to the edge with extra benefits. At the core, RunX is an OCI-compatible containers runtime to run software packaged as containers as Xen micro-VMs. RunX allows traditional containers to be executed with minimal overhead as virtual machines, providing additional isolation and real-time support. It also introduces new types of containers designed with edge and embedded deployments in mind. RunX enables RTOSes, and baremetal apps to be packaged as containers, delivered to the target using the powerful containers infrastructure, and deployed at runtime as Xen micro-VMs. Physical resources can be dynamically assigned to them, such as accelerators and FPGA blocks. This presentation will go through the architecture of RunX and the new deployment scenarios it enables. It will provide an overview of the integration with Yocto Project via the meta-virtualization layer and describe how to build a complete system with Xen and RunX.

State of Linux Gaming - Gabriel Krisman Bertazi, Collabora
For too long, Windows has been the de facto platform for any serious gaming on computers. In fact, there is still much resistance by game studios from supporting multiple platforms, which can be explained in part by the specific challenges of porting them. Computer games are prime examples of complex applications who need to squeeze every bit of processing performance possible out of the system, usually making use of very specialized engines who exploit very specific features of the platforms they were designed for. Instead of waiting for studios to port their games, Wine, and the more recent Proton effort, attempt to fully emulate the original environment these games rely on. Much of this work, though, can only be done efficiently with specialized support by the kernel. In this talk, we will review the recent efforts to improve Linux support for emulation, always with the goal of enabling and speeding up recently released games on Linux. In addition, we will discuss specific pain points for emulation on Linux that we plan to solve in the near future.

Deploying Linux in Safety Critical Applications - Three Key Challenges - Christopher Temple, Arm Germany GmbH
The next wave of highly automated and highly dependable automotive and industrial systems are driving a strong desire to deploy Linux in such systems. While dependability attributes like availability, safety and maintainability have already received attention in existing application domains like cloud computing the safety aspect is new. The safety aspect for Linux revolves around three key challenges. Firstly, the OS needs to provide specific services with sufficient safety properties to the safety application. Secondly, the OS needs to show intrinsic safety in a way that the OS itself does not become a source of hazardous operation. Thirdly, the OS needs to be able to interface adequately to underlying safety hardware such that safety properties provided by the hardware are enabled and maintained, and no new uncovered safety issues are introduced. The presentation will discuss issues and ideas around identifying sufficient safety properties, the challenges and potential solutions around intrinsic safety, and the state-of-the-art around safety enabled hardware and related integration needs in light of different application classes.

Ready to Switch to Open Hardware GNU/Linux PowerPC Laptop? - Roberto Innocenti, Not Profit Power Progress Community
Why today is possible to switch to a Open Hardware GNU/Linux PowerPC Laptop? As not profit association based only on volunteers I share the steps of our experience on design the eletrical schematics and the PCB of the Open Hardware PowerPC Notebook. Why we have choose the CERN Source Hardware License, and why we are ready for the OSHWA Certification process. How we have solved the problem to have the body of the laptop even for a small production in a non standardized and non-modular world of Notebook Chassis. Why thanks to FOSS its possible ( but not necessary simple) to have an OS and applications run in a today less Common Architecture in Consumer market, like Power Architecture ( PPC64) Big Endian. Good practice of writing open source codes not Endian Dependent its important to run GNU/Linux applications on every CPU Architecture. Our experience finding code written only for little-endian that we need that run on big-endian CPU.

Lightning Talk: Give Open Source the Weight it Deserves in Public Policy - Sivan Pätsch & Paula Grzegorzewska, OpenForum Europe
When the last study on Open Source in Europe was concluded in 2006, the Open Source revolution had not yet taken over the world. Today Open Source Software is ubiquitous in business and Open Source Hardware could trigger the next revolution. Yet policymakers don’t have the data they need to treat Open Source as the innovation machine it has become. What is the value of Open Source for the economy? How many jobs does it support? How can innovation through Open Source be measured? Is Open Source as beneficial for innovation as we think? What do governments need to do, or not do, to support a flourishing Open Source ecosystem? Since the beginning of 2020, Fraunhofer ISI and OpenForum Europe, working with over 100 researchers around the world, have been tasked by the European Commission to research the value of Open Source Software and Hardware. During this presentation we will share some preliminary takeaways and tell you why we need your input to make a pro-open source policy a reality.

Linux Tracing with BPF, BCC and More - Mauricio Vásquez Bernal & Alban Crequy, Kinvolk
BPF is a virtual machine inside the Linux kernel that allows to load user defined programs that are attached to different kernel hooks (kprobes, tracepoints, uprobes, etc). One BPF’s application is to perform tracing at the kernel level as BPF programs can capture information about different kernel events. BCC (BPF Compiler Collection) is a set of libraries for different languages such as Python, C++, Lua and many ready-to-use tracing tools.  This talk will give a quick introduction of BPF. It’ll present an introduction to the BCC project and its features. A demo of the more popular BCC tools will be done. It’ll also show how to create (or customize) your own tools. Finally, it’ll show how BCC is integrated with other projects to perform tracing in cloud environments like Kubernetes.

Comprehensive Observability of your Microservices Using Deep Linked Metrics and Traces - Ryan Allen, Chronosphere Inc.
Metrics are the perfect tool for setting up alerts and being notified when something goes wrong. Once you get notified, if the root cause of the issue is not obvious, it’s great to have other tools such as Distributed Tracing to get more details. It’s already hard enough to get from the metrics behind your alerts to the exact underlying problematic traces, but even when you get there, you often want to compare a problematic trace with a non-problematic one to determine the differentiators and help root cause the issue. This talk will demonstrate how you can link and jump straight from an alert notification to an underlying problematic trace along with how you can make use of the associations in the metrics space to get to a comparison with a non-problematic trace. This is accomplished with a combination of open source tools such as Prometheus, Jaeger, Grafana and M3. The audience will learn how recent advances in the community can enable them to reduce their time-to-mitigation by providing the relevant context of a good vs bad request directly from an alert notification. The talk will go over different scenarios and techniques from the one being presented at Kubecon EU.

Development "Interrupt Storm Detection" Feature - Kento Kobayashi, Sony Corporation
While developing an embedded device, a developer may have to diagnose and fix an interrupt storm. An interrupt storm is when a continuous stream of interrupts occur due to hardware or device driver failures. Interrupt storms can hang the system and make debugging very difficult. Two ways to analyze interrupt storms are using a JTAG and using CONFIG_PSTORE_FTRACE functions. However, with these methods, it is required to prepare the JTAG hardware and JTAG settings file, analyze the acquired information, and so forth.  It also requires the user to specify the interrupt number related to the interrupt storm. To make debugging interrupt storms easier, we have developed an "interrupt storm detection" feature. This feature works by checking whether the number of interrupts within a certain period is over a threshold and then notifying the user. The Linux kernel already has an interrupt storm detection feature for spurious interrupts. However, this new feature detects storms for interrupts other than spurious interrupts and gives the developer control over the storm detection parameters.

Simplify and Reuse Your Driver's Code with Regmaps - Ioan Adrian Ratiu, Collabora Ltd
Regmaps allow you to abstract register-access by mapping memory regions to registers. At a first glance, one may not see the benefit of using regmap instead of directly calling the standard readl/writel functions. However, regmaps, as a register layout abstraction, bring more flexibility to the table: with regmaps you don't hold on to the specific details of your hardware register layout, opening the door to get your code to use slightly different variations of the same hardware platform just by setting the right register mapping at the driver's init phase. In this talk we will discuss this advantage and few others while looking at real examples where regmaps were used in mainline in the MIPI-DSI and Hantro media accelerator drivers.

Virtual Topology for Virtual Machines: Friend or Foe? - Dario Faggioli, SUSE
Being able to craft a detailed virtual topology for a VM may be crucial for achieving good performance. But it is also risky, as interfaces become more complex, and an inconsistent configuration may be selected, causing more harm than good.

E.g., it would be good to be able to specify the size of caches, for cases when some software (e.g., glibc) inside the VM checks it and decides whether or not to enable some optimizations depending right on that.

On the other hand, even just defining the vCPUs topology (threads, cores, NUMA nodes, etc) may lead to less stable or outright worse performance, if the vCPUs and the memory of the VM are not properly pinned at the host level.

In this talk, we will show some first-hand examples, we will outline what is currently there in Linux, libvirt and QEMU and we will discuss if it is possible to improve things even further.

A Faster Hibernation/Resume Using Opportunistic Memory Reclaim - Andrea Righi, Canonical
Hibernation is usually considered as an obsolete feature for laptops, but it can still provide significant benefits in many different scenarios, if it can be made to work reliably and efficiently. The main bottleneck of hibernation is the cost of I/O, both at hibernation and resume time, but it is possible to reduce this cost using opportunistic memory reclaiming techniques. Canonical has been actively experimenting hibernation in cloud computing and virtualized environments. In the process we had the opportunity to experiment some improvements and learn surprising lessons. This session shares some technical details of the solutions that we developed, the lessons learned and the results that we found.

Syscall Supervision - Christian Brauner, Canonical
Unprivileged programs such as containers employing user namespaces are severely restricted by the kernel to protect the host from malicious workloads. This means that certain syscalls are completely off-limits for critical workloads even when a privileged, supervising process such as the container manager can vouch for the safety. To solve this problem in a generic way we extended the Linux kernel to allow for syscall supervision. This means a process such as the container manager can receive notifications about the syscalls of a process running inside the container which remains blocked until the container manager allows it to proceed. In this talk we will look at how syscall supervision works in the kernel and how a container manager can use it to allow unprivileged containers to mount filesystems and create devices it would otherwise not be able to. We will also look at new features built on top of this enabling a container manager to inject and receive file descriptors from another process allowing to open() files for the container it would otherwise not be able to open.

The Importance of Non-code Contributions to Code-centric Open Source Projects - Marcel Kurzmann, Bosch
Handling Open Source Software in a compliant way requires a good Open Source Management that keeps you busy already. On the technical side, the component often can be downloaded, integrated and functionally tested within minutes. But what about the so called non-functional requirements.

For some Open Source Components, the necessary information as input for the Open Source Management is hard to find or even completely missing. Thus technically you can download and run the stuff, but from a legal perspective it might be, that you are not allowed to. Not because the Open Source Project wanted to actively avoid it, but the necessary "non-functional" requirements were not fulfilled yet.

This talk will show some examples for non-functional requirements, the experiences we have made at Bosch.IO with missing information and potential work-arounds. As the problem needs to be resolved at the root, the talk will highlight some community activities running that address these issues like clearlydefined.io, reuse.software, sharing-creates-value and sw360.

Federated Monitoring Leveraging Open Source Technologies - Sanchit Sandeep Pathak & Akhil John, Platform9 Systems, Inc.
Since the advent of containerized infrastructure, one can’t simply extend the monitoring strategy that worked for VMs and expect it to work for containers. Due to container portability and the rise of Kubernetes, the need to adopt multi-cloud strategies has added even more complexity to application monitoring. The main reason is that Kubernetes adds another multi-component layer to software environments that must be monitored. One has to keep track of the health of the cluster, pods, containers, storage, and networking components within the cluster along with monitoring the applications and the underlying infrastructure itself. The application as a whole, Kubernetes itself, and the infrastructure can have issues under the unforeseen circumstances. To stay ahead of these issues, there is a need to have a comprehensive monitoring regime that addresses all the layers of a containerized, Kubernetes based environment. This proposal talks about taking a three-tiered approach to Kubernetes monitoring by identifying key pillars to adopt in order to monitor workloads most effectively with the use of open-source tools like Grafana, Prometheus, ELK and Cortex.

How Open Source is Helping to Save the World - Kara de la Marck, CloudBees
The Internet is a driving force that is democratizing the world. Now more than ever, innovation needs to spread as fast as information. It is impossible for one governing body, one company, or one human to come up with the innovative solution to address global challenges surrounding legal issues, security, environmental issues, diversity issues, and more. These challenges are shared by all humans and it takes a concerted effort by all to help shape the solutions today for the problems of tomorrow. It is important that we maintain the principles and practices for creating diversity and inclusion to enable ways for everyone to participate in a project or a cause. In this talk, we will challenge everyone to consider how we can take a software solution and apply that to a humanitarian problem. In this talk, Kara will explore how open source brings people together to share data, best practices, and how to work as a global community. She will highlight frameworks and patterns for transparency and interoperability so that a community can learn about what’s working, what isn’t, and how to get away from fragmentation in ecosystems where nobody knows what’s what.

The Common Challenges of Secure VMs - Janosch Frank, IBM
Secure VM technology on multiple architectures has been introduced in the last few years and is slowly gaining ground. The goal of protecting VMs against accesses and manipulation from the hypervisor can be achieved in many ways. However the challenges to get a secure VM up and running are mostly the same no matter the architecture and secure VM technology.  Let's have a look at the goals that secure VMs want to achieve, the challenges that need to be overcome to run them and how the architectures solved them. Also let's try to have a look into the future which will bring us secure VM migration, dumping and more device support and try to anticipate the challenges that are still waiting.  If we take a step back and have a look at the problems that are common to all architectures we might be able to find a common solution.

Real-time Linux: What is Next? - Daniel Bristot de Oliveira, Red Hat
With the PREEMPT_RT mainlining, is the real-time Linux development ended? - No! It is the beginning of a new era. The low latency provided by the nowadays communication channels and the need for a software stack for AI/ML present on Linux is enabling a new class of cyber-physical systems that depends on real-time kernel. But, is the real-time kernel ready to be used in such scenarios? This presentation is a discussion about the current state of Real-time Linux. It will talk about the kind of determinism that is possible to obtain with Linux and the type of determinism that is still not possible to achieve. The main goal is to point to the next opportunities in the development that can enable Linux for a class of systems that requires more robust evidence of correctness, including the formal verification of the kernel and the mathematical analysis of the timing properties of the kernel.

The Compact C Type (CTF) Debugging Format in the GNU Toolchain: Progress Report - Elena Zannoni & Nicholas Alcock, Oracle
The Compact C Type Format (CTF) is a reduced form of debug information describing the type of C entities such as structures, unions, etc. It has been ported to Linux (from Solaris) and used to reduce the size of the debugging information for the Linux kernel and DTrace. It was extended to remove limits and add support for additional parts of the C type system. Last year, we integrated it into GCC and GNU binutils and added support for dumping CTF data in ELF objects and some support for linking CTF data into a final executable (and presented at this conference). This linking support was preliminary: it was slow and the CTF was large. Since last year, the libctf library and ld in binutils have gained the ability to properly deduplicate CTF with little performance hit: output CTF in linked ELF objects is now often smaller than the CTF in any input .o file. The libctf API has also improved, with support for new features, better error reporting, and a much-improved CTF iterator. This talk will provide an overview of CTF, the novel type deduplication algorithm used to reduce CTF size and discuss the other contributions of CTF to the toolchain, such as compiler and debugger support.

The State of Open Source Licensing Clarity (or the lack thereof) - Philippe Ombredanne, AboutCode.org and nexB Inc.
In an ideal world, the provenance and open source license of third-party software would be available as easy-to-discover structured data. 

We are not there yet!

We will review a detailed study on the clarity of licenses documentation practices in 5,000 popular open source software packages and infer the state of licensing clarity globally gained from the insights and statistics from the analysis of millions of package with ScanCode toolkit in the ClearlyDefined project.

And we will discuss what can be done to improve the situation. I will present the state of the license documentation clarity in the open source community at large through the lens of:

1. the introduction to the license clarity metrics we designed for ClearlyDefined and the ScanCode toolkit
2. the presentation of a study of the license clarity of 5000 popular open source projects across multiple programming languages and ecosystems
3. an overview of the statistics on license clarity across 10M packages

The take away for the participants will be a better understanding of where we stand in terms of license clarity globally, the discovery surprising and non-intuitive insights from our large study, and what can be done to improve the situation.

Collaborative Leadership: Governance Beyond Company Affiliation - Dawn Foster, VMware
The unbridled success of Kubernetes can be attributed in part to being in the CNCF. Putting Kubernetes under a neutral foundation provided a level playing field where each of us could contribute, collaborate, and innovate as equals to create a widely adopted solution that we can all use. Open source projects that are controlled by a single company are at a greater risk of changes that are not aligned with community interests, whereas projects that are under neutral foundations have a lower risk both for end users and software vendors. With advantages that include community building, innovation, and wider adoption, we should consider contributing more of our open source projects to neutral foundations, like the CNCF.

This talk will cover:
  • Challenges of giving up control and why it might be worth it.
  • Selecting a foundation and how to determine neutrality.
  • Creating a fair and neutral governance structure and processes for your project.
  • Tips for contributing and maintaining your project. 

The audience will get practical advice about whether they should contribute their projects to neutral foundations along with how and when to do it.

Fast Execution for Function Compositions in Serverless Computing - Ruichuan Chen & Istemi Ekin Akkus, Nokia Bell Labs
Serverless computing has rapidly gained traction with its promise of continuous scaling and low costs without the hassle of managing servers. Though it was originally aimed for running single functions, developers have embraced it to compose scalable applications with multiple interacting functions. However, many platforms map individual functions of an application into their own containers and require them to be stateless. This creates the biggest downside of serverless computing: serverless applications suffer high performance penalties from long invocation delays among functions and slow access to externalized application state. In this presentation, Ruichuan and Ekin revisit these design choices and propose an alternative with KNIX: grouping an application’s functions in the same container as separate processes while isolating different applications in different containers. Coupled with process forking and locality mechanisms, this design allows function executions to start and interact about an order of magnitude faster compared to current serverless platforms. In addition, it examines the use of stateful, addressable function executions for fast access to application state.

Keep Your Project Healthy: Grow Your Contributors - Kendall Nelson, OpenStack Foundation & Guinevere Saenger, GitHub
Open Source is a difficult concept to teach people because there isn’t anything in life that is truly ‘free’. Even more difficult than explaining what open source is in the first place, is teaching ways to openly collaborate and work together with people from other companies and places in the world. When you consider that some open source projects literally span the globe, and are worked on by thousands of contributors, this job gets even more difficult. In this talk, you will hear about the best practices Guinevere and Kendall have discovered through their work on the Kubernetes New Contributor Workshop and the OpenStack Upstream Institute trainings that teach attendees how to contribute to these projects. The struggles they have faced and overcome are applicable to all open source projects developing training on getting new contributors started.

Supporting Hardware-Accelerated Video Encoding with Mainline - Paul Kocialkowski, Bootlin
The media subsystem and the V4L2 API have recently been extended to support hardware-accelerated video decoding for stateless implementations, with drivers such as cedrus and hantro supporting embedded platforms like Allwinner and Rockchip. While the stateless decoding work is being finalized, the next order of business is stateless video encoding. This talk will present the research and first implementation attempts to support H.264 encoding, using the Hantro H1 hardware. It will start with an introduction to H.264 encoding and rate-control approaches, one of the key aspects of encoding. It will follow with details about the hardware and provide an overview of the implementation challenges, choices that were made and their limitations for a common interface that can apply to any kind of stateless H.264 encoder. With that, a general picture of what a generic stateless encoding API for V4L2 would look like will be drawn.

The International Effort to Establish Open Source Base Layer of Cyber Security for IACS - Kento Yoshida, Renesas Electronics Corporation
The targets of cyber-attacks are changing from information assets to Industrial Automation and Control System (IACS). In order to deal with evolving cyber-attacks, IACS must be kept secure. IEC-62443 series is the international standards of cyber security for IACS and recently have received great attention from around the globe. The Civil Infrastructure Platform (CIP) project that intends to create Open Source Base Layer (OSBL) also places importance on IEC-62443 series. The CIP security working group launched by the members from Germany, India, Taiwan and Japan leads activities to make the CIP software development process compliant with IEC-62443-4-1, and create the core package set to meet security requirements in IEC-62443-4-2. The primary objective of this group is to dramatically reduce certification cost for end product as well as help suppliers to efficiently utilize our artifacts. Suppliers would need to meet only few IEC-62443-4-x requirements by harnessing certified CIP platform for IEC-62443-4-1 and 4-2.

The Yocto Project on Windows - Alejandro Enedino Hernandez Samaniego, Microsoft
The Yocto Project and OpenEmbedded are widely used across the world for their great capability for building customized Linux distributions and applications for embedded products. However, due to inherent characteristics of the compilation process and toolchain, the build required being executed on a native Linux host, this is sometimes a limitation since Windows is used by most companies employees and in this case can't be used as a development system. The previous statement is no longer true, the Yocto Project can be used under Windows, allowing developers to have easy access to a development system increasing productivity and efficiency. This presentation will guide the audience through the process of creating Linux operating systems and applications on Windows, introducing them to the Windows Subsystem for Linux (WSLv2), compare usability, performance and include personal experience while performing this task, performing a demonstration of its usage interactively.

Virtualization for the Masses: Exposing KVM on Android - Will Deacon, Google
Despite virtualisation hardware being implemented in all arm64 Android devices, it is seldom available to KVM and instead tends to run bespoke payloads targeting security and data isolation.

The Android-KVM project at Google aims to extend upstream arm64 KVM to cater for the requirements of mobile guest payloads. Of critical importance is the notion that the host cannot access guest memory without the explicit permission of that guest. This requires a split between the KVM code at EL2 and the host kernel at EL1, along with standardised communication between the host and its guests for mutually controlled shared memory instantiation and a degree of portability between hypervisor implementations.

This presentation will offer a quick tour of the arm64 virtualisation architecture before diving into some of the challenges and open problems that we have faced while enabling KVM for Android.

The QEMU generic machine emulator and virtualizer includes a wide range of emulated devices. These devices can be very useful for debugging a software stack and for prototyping new features that is yet to be available in hardware and firmware. In this technical talk we focus on "prototyping new features" in the emulated NVMe device. We will go through the core event loop of the upstream device and explore how the recently ratified Namespace Types and Zoned Namespaces NVMe Technical Proposals can be implemented. Finally, we will design a custom (non-spec) command and go through a prototype implementation. We will then discuss how such a QEMU prototype implementation helps when developing the associated software stack and see how the feature can be tested and verified from a Linux host.

Lightning Talk: Open Source Software-Defined Storage for All-Flash Array Management - Vicki Chu, Industrial Technology Research Institute
All-Flash Array is replacing traditional hard disk drive to become the main data storage medium for enterprises and cloud data centers. However, flash memory has the inherent drawbacks of low performance for random write access and lifespan. In this talk, Vicki will introduce the open source All-Flash Array software-defined storage system, SOFA (Software Orchestrated Flash Array), developed by ITRI to free the flash memory from these two constraints with intelligent algorithm and system optimization. SOFA is to build a system software running on a storage server equipped with a flash memory disk array. Its main advantages are to provide high data protection while also achieving high random access. The system provides a block device for users to read and write data, and data will be stored distributedly across all SSDs by RAID5 protection. The technology breaks through the performance barrier, as exhibited by conventional approach of hardware or software based RAID5, and simultaneously doubles the lifespan of disk array by proprietary Global Wear Leveling mechanism.

Being Fluentd with Logs - Phil Wilkins, Capgemini UK
Understanding what is happening with applications, particularly in a distributed solution (microservice or scaled monolith) can be challenging. Whilst the solution space for monitoring and application log management is mature, there is a tendency for organizations to end up with multiple tools which overlap in this space to meet different needs, or one tool not meeting all needs. Many of these tools work by bulk central analysis rather than enabling events of interest to be spotted as they’re logged. Fluentd presents us with a means to achieve a monitoring capability allows us to choose the log analytics tool(s) that meet our needs. We can create the chance to become more reactive or even proactive. Ease the complexity of hyper-distribution with microservice and serverless solutions. In this session we’ll explore the challenges of modern log management. We’ll look at how Fluentd works and what it can bring to making both development and ops activities easier. To do this we’ll explore and demo some examples of Fluentd and how it makes life easier & more effective.

Burnout - When Your Mind is Tired - Jan Altenberg, Continental Automotive GmbH
Over the past few years burnout has become an increasingly serious topic for companies and for Open-Source communities. High demands in our working environments and constant availability by email, phone and social media are only a few of the factors that can increase our stress level drastically. People working on Open-Source are usually highly skilled and passioned for what they are doing. Bringing all these facts together the risk of suffering a burnout can be extremely high. Therefor it is essential for all of us to get a better understanding for this topic: As a company, as a community and as a developer. Based on personal experience Jan Altenberg will give some insights about the phenomenon of burnout, how to spot symptoms early and how to deal with it as an affected person, as a co-worker and as a team leader. Furthermore, this presentation wants to raise awareness for this subject which still seems to be a “taboo topic” in many companies and communities.

Let’s Test with KernelCI - Khouloud Touil, Baylibre
A growing number of Linux developers want to use KernelCI to run their test suites, but there’s a bit of a learning curve for how to make test suites work with KernelCI.  “Let’s Test with KernelCI” will give an overview of the ways to integrate test suites and/or test results into the KernelCI modular pipeline. One option discussed will be having the kernelci.org service run the test suites for you and collect the results. But many developers and companies have existing test and automation infrastructure already running, so we will also discuss how to leverage existing infrastructure. Another option is to take advantage of already running test infrastructure and submit test results to KernelCI.

The State of PTXdist - Roland Hieber, Pengutronix
PTXdist has been around as a build tool for Embedded Linux systems for more than 16 years now. During its monthly release cycle, besides the usual maintenance tasks, useful features are continuously being added. In the last years, these included support for kconfig deltas and layered BSPs, infrastructure for cryptographic code signing and license compliance, support for reproducible builds, and online reference documentation. With its configuration menu for selecting the software packages for your target system, and a template wizard for creating new packaging rules, PTXdist makes it possible to get a booting BSP in almost no time. Advanced users will feel familiar with PTXdist's makefiles, and can profit from fast edit-compile-run cycles by using nfsroot and cross-gdb integration. This talk gives an overview over the core concepts and the current feature set of PTXdist, and is intended for new as well as old users. This talk is based on a submission from FOSDEM 2020, and will also include the developments in the last six months, as well as set its focus more on the usability features.

Optimizing for NVMe Drives: The 10 Microsecond Challenge - Stefan Hajnoczi, Red Hat
Solid-state storage devices with request latencies of less than 10 microseconds pose challenges for virtualization. Even small overheads result in a visible reduction of I/O performance. Solving this requires changes to the I/O stack.

This talk covers recommended tuning and current work on improving I/O performance for QEMU guests with NVMe drives.

The first part to achieving good I/O performance is to ensure that the guest is taking advantage of multicore and NUMA effectively. This involves both manual tuning and recently added optimizations for getting the most out of the hardware.

The second part is efficient I/O request submission and completion. Traditionally this involved vmexits and eventfds, but improvements to QEMU's AioContext polling can eliminate them and achieve much higher performance.

Come find out how close to bare metal performance QEMU gets!

Customized Trace Data Visualization with KernelShark - How to Write User Plugins. - Yordan Karadzhov, VMware
KernelShark is a front-end reader of tracing data and its data visualization capabilities have been proven very useful. Nevertheless, there are cases when the user has specific needs, that go beyond what is provided by the built-in visualization model. Although, the user customization was one of the key features incorporated in the design of KernelShark v1, the possibility to write plugins was not taken advantage by the KernelShark users. We believe that this will change with the release of KernelShark 2.0. The new version includes a substantial improvement to the infrastructure for plugins. The plugin development process was greatly simplified, while at the same time the user has more ways to customize. This talk will be a brief overview of how to create your own plugins and will demo some of the new key features in KernelShark 2.0, that are implemented in the form of plugins.

Public Money? Public Code! – What Role does Free Software Play after the Corona Crisis? - Alexander Sander, Free Software Foundation Europe
In a time when humanity needs to work together to find solutions for a crisis, we cannot afford to reinvent the wheel again and again for software that helps us tackle the spread of COVID-19. Global problems need global solutions! It is Free Software that enables global cooperation for code development. During the crisis we have seen a lot of Free Software and projects trying to tackle the crisis like tracing apps, hackathons or solutions for remote working - but what will happen after the crisis?

Already before this crisis hundreds of organizations and tens of thousands of people demanded that publicly financed software developed for the public sector must be made publicly available under Free Software licenses.

In this talk, you will learn about the advantages of using Free Software in the public sector, about the learnings from the corona crisis and why it is now even more important to use Free Software than ever before.

Lightning Talk: Unravelling the Linux Kernel Using BPF Raw Tracepoints - Abhijit Singh, Uber
This talk aims at presenting the potential of BPF raw tracepoints. In a static tracepoints present in the Linux kernel, a dynamic tracer like ftrace or kprobe+bpf, might not get desired information about arguments passed in the tracepoint(e.g. many fields related to the task_switch struct aren't accessible such as nvcsw and nivcsw in the sched_switch tracepoint). With the introduction of BPF raw tracepoints, we can create a BPF program which can investigate each argument being passed to the tracepoint upon its invocation. The talk will commence with the rationale to introduce a raw BPF tracepoint. It would then present the signature of the BPF_RAW_TRACEPOINT api. It would also present a couple of example BPF programs which use raw tracepoints. 1) a program which prints the arguments being passed to the openat system call 2) a program which calculates total involuntary context switches, voluntary context switches over time for a system The talk would also highlight the low performance overhead of raw tracepoint as compared to other tracing infrastructure like kprobe+bpf.

Are You Wise in the Ways of Open Source Compliance? Taxonomy and the Tools of Open Source Compliance - Gergely Csatari, Nokia & Yann Jorelle, Nokia/Aalto University
Different organizations do open source compliance differently. The approach, the level of automation and the compliance practices vary. In addition different open source communities have created a selection of tools for the compliance verification. Some tools fit some approaches better than other. But how does my organization’s approach compare to another organization’s? What tools could be useful for me? Are the tools any good? In order to compare approaches, tools and see what fits and what doesn't, the industry needs a common way to name and address the different steps in the open source compliance process. This presentation dissects the open source compliance checking steps, names and describes them (Sir Bedevere, wood, and a duck. Or was it lead?). It also describes the different approaches different companies take to executing these steps, particularly describing the Nokia approach. As a practical step, the presentation shows the results of our study to investigate how the current open source compliance tools perform the different steps of open source compliance. We might also relieve if the tools weigh the same as a duck…

Flies Like an Arrow: Open Source Compliance with Scale in Telco Environment - Ingrid Viitanen & Jonne Soininen, Nokia
Nokia is one of the leading players in the telecommunications industry. Nokia has multiple business groups with hundreds of products and tens of thousands of engineers. Nokia's product portfolio ranges from highly embedded products working on specialized hardware to cloud native applications. Naturally, many of these products use open source of some kind. Needless to say, Nokia operates at scale. This requires a scalable and adaptable open source process that ensures open source compliance while enabling the product creation with minimal interference. This presentation will describe how this was done. How Nokia build a flexible open source process that enables Nokia's product creation taking also into account the need for the product groups to contribute to open source while working in the upstream first and how the Open Source Program Office (OSPO) was organized to take into account the legal, open source and patenting aspects.

Inference on (the) KubeEdge - Adrian Gonzalez-Martin, Seldon
Machine learning models usually make predictions based on data coming from a wide range of IoT devices. If we think of images, audio recordings or brain waves we can see that they are all measured using hardware sensors. After being read, this data is usually sent to remote clusters where inference is performed. Wouldn’t it be great if we could expand these devices to also make predictions? Edge computing can help to address the privacy, latency and data ownership concerns by bringing this computation to the “edge”. In this talk we will discuss these concerns and we will introduce KubeEdge as a solution to treat our edge devices as Kubernetes nodes, which will enable us to use existing Kubernetes tools to deploy machine learning models and perform real-time inference.

Monitoring at Global Scale with M3 and Prometheus - Gibbs Cullen, Chronosphere
For the past few years Prometheus has solved the monitoring needs of many and it is exceptional at what it does. Prometheus has exploded in popularity and now many wish to store more metrics, at longer retention and establish a single pane of glass on top of Prometheus for their monitoring needs across regions.

 M3 is an open source metrics platform that you can deploy and run using Kubernetes and Helm that integrates with Prometheus. It can store petabytes of metrics data with replication for high availability in a cost efficient manner, with compaction averse time series storage and index that can efficiently index and run dimension based regexp queries on billions of metrics.

 Using a real world example we will cover in this talk how to deploy M3Coordinator and M3DB using the M3 Kubernetes operator and connect your Prometheus instances together into a single global monitoring system.
