When developers make changes to core CPython, a set of scripts which builds the core Python code and runs tests on Linux, Windows, FreeBSD, and other platforms happens. These scripts run under a framework called Buildbot ( https://buildbot.net ). For quite some time, Python was using an older version of Buildbot which only ran under Python 2. This talk will cover my efforts to port the Buildbot to Python 3, and how I worked with the Python Buildbot team to help them upgrade their buildbot cluster at ( http://buildbot.python.org/all/ ) so that they use Buildbot running under Python 3.

Presented at: Config Management Camp, Ghent, 2020-02 Kubernetes provides a declarative API, so you can describe the desired state of the system. And then it is the role of the control plane to operate the cluster (make the actual state match the desired state). But we still need config mgmt for API objects to the point when they are applied to the cluster. Helm helps to organize these configs into charts, template them, and manage releases. And GitOps lets you use a git repo as a single source of truth for the desired state of the whole system. Then all changes to this state are delivered as git commits instead of using kubectl apply or helm upgrade. In this talk I will introduce the GitOps model for operating cloud native environments and give a short demo. In this talk I show two CNCF projects: - Flux CD: https://fluxcd.io/ - Helm: https://helm.sh/

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.

The Web engine is the most important component of a Web Browser, enabling developers to harness the power of the Web Platform to build their applications. However, Web Browsers are not the only type of applications that can be built with Web Engines, which can also be used to develop other types of applications using the same Web-based technologies, but for a different type of use cases other than "browsing the Web". These use cases can cover a wide range of situations outside of the traditional desktop or mobile environments, such as the ones embedded systems are usually used for (e.g. set-top-boxes, smart home appliances, GPS navigation devices, or in-car/in-flight infotainment systems, to name a few). And in those situations it is very common to be running on boards with SoCs and a particular set of HW capabilities that make it crucial for the Web Engine to be able to tightly integrate with them. In this session we will focus on how WPE, a fully Open Source port of the WebKit Web engine for Linux-based embedded devices, can be used to adapt to the different challenges that embedded devices pose to develop end-user applications, using the power of the Web Platform underneath.

The Raspberry Pi 5 was announced on October 2023. This new version of the popular embedded device comes with a new iteration of Broadcom’s VideoCore GPU platform, and was released with a fully open source driver stack, developed by Igalia. The presentation will discuss some of the major changes required to support this new Video Core iteration, the challenges we faced in the process and the solutions we provided in order to deliver conformant OpenGL ES and Vulkan drivers. The talk will also cover the next steps for the open source Raspberry Pi 5 graphics stack.

Every day, embedded devices are becoming more powerful and capable of running more elaborate applications. Among these applications are Web-based ones, enabling to leverage features from the Web APIs to the embedded context, either through a generic browser running a traditional Web application or through a customized Web engine tightly integrated within the system. But such capabilities usually bring new challenges, like testing user interactions with the application using the embedded device's specific I/O methods, such as gestures, or inspecting Web application internals with JavaScript. In this context, using a browser automation framework such as WebDriver, which is a W3C standard supported by WebKit Web engine, allows testing Web-based applications on such devices as if the user were actually using it, alongside running custom JS code. In this session, we will cover why we need browser automation for testing on certain types of embedded devices, with a focus on WebDriver as the proposed tool to achieve that goal. We will also discuss WebDriver's main features and limitations, as well as other possible approaches and frameworks that could be considered for this kind of task.

Embedded devices have become powerful enough to run Web content a decade ago, and any modern SoC that can run Linux and includes a GPU is a potential candidate to hide a Web engine under the surface. How did it made it there? Does it only show Web content? What else can it do? The talk will cover bring-up tips to build and get WPE WebKit working on your custom embedded device and make your own simple Web browser, as well as the best practices for keeping the system up to date. No less important is integration with the rest of the system: this session will detail the possibilities that WebKit brings to the table, including how to add new JavaScript APIs which call into native code to provide tight, performant access to platform functionality.

This talk dives into how the scheduler impacts your gameplay on Linux and unveils our journey to smoother gameplay. How does task scheduling impact Linux gaming? Suboptimal task scheduling can cause stuttering while playing games on the Steam Deck game console. First, we nail down the enemy. What exactly is "stuttering," and how can we measure its impact on your gameplay? Next, we extensively analyzed the characteristics of game tasks from the scheduler’s point of view. Characterizing task behavior in Linux gaming helps to understand why some schedulers create much stuttering and others create less and to unveil the secrets behind smooth vs. choppy performance. Lastly, we will share our progress on the optimized scheduler for reducing the stuttering problems in Linux gaming, especially Steam Deck. We implemented the scheduling policy based on sched_ext, a BPF-based extensible scheduling framework.

So, we are adding a backend for the SpiderMonkey’s codegen to enable JIT support for JavaScript running through Wasm. Sounds a bit cryptic so let’s divide it into parts. SpiderMonkey is a JavaScript engine which is used for running JavaScript inside the Firefox browser. SpiderMonkey is written in C++ and supports compilation into the Wasm module, see live demo - https://mozilla-spidermonkey.github.io/sm-wasi-demo/. However, SpiderMonkey compiled into the Wasm module supports execution of JavaScript only in the interpreter-only mode and it doesn’t support just-in-time compilation because there is no Wasm backend for that. There are backends for Arm, X86, X64 etc but there is none for Wasm. Why do we want to add support for JIT? Well, because we want speed. Right now there is no solution to run JS scripts via Wasm fast, there are only interpreters. Why does JIT improve performance? The reasons are the same for why an interpreter is slower than a compiler - because it eliminates the interpreter loop, uses a more efficient ABI and, more importantly, it can specialize polymorphic operations in JavaScript. So, we not only enable the JIT tier in SpiderMonkey for Wasm but we also provide support for inline caches. Inline caches is a mechanism for specializing the behavior of particular operations like plus or a call to specific arguments provided at runtime. With all that we can generate Wasm modules on the fly, instantiate them, and link them to provide from ~2x to ~11x speedup over the interpreter. In the talks we will cover how the whole scheme works with SpiderMonkey: 1. How to link modules on the fly into SpiderMonkey.wasm 2. How to add an exotic Wasm backend into SpiderMonkey’s supported backend line - X64, X86, Arm, Wasm 3. How to use the whole solution in the cloud instead of QuickJS 4. How to get a speedup of your JS over wasm with test data. Wasm I/O 2024 14 - 15 Mar, 2024 Barcelona https://2024.wasmio.tech/

What could be possibly worse that an almost unbeatable boss in a game or a tough maze that consume hours of gameplay with not much progress? How about a Linux kernel crash that makes you lose all the game progress with no apparent reason or feedback? Though rare, it is a real possibility that would make gamers quite annoyed, given that Linux is used more and more as a platform for playing games. Some technologies are available to collect logs and feedback the user in case such disastrous events happen, mostly related with kernel crashes handling mechanisms. The main ones available are kdump and pstore, but still there are work to be done in this area... In this talk we're going to present the basics about kernel crash handling, like how a kernel panic might happen, how to deal with that (with an overall discussion about kdump and pstore techs) and the kdumpst tool, developed specially to deal with this situation on Steam Deck (and generically on Arch Linux); also we're gonna discuss some missing pieces / ideas to make it even less likely gamers need to complain that their device just got hang for no reason!

Chimera Linux is a novel Linux distribution built around FreeBSD core tools and the LLVM toolchain. Since its initial launch in 2021, it has made a lot of progress and is now in alpha stage. The system can be deployed on a wide array of hardware and many people are using it as their desktop system; it works on x86_64, AArch64, POWER (little and big endian) as well as RISC-V and by now comes with thousands of packages. While trying to be practical, Chimera is also highly hardened, partly thanks to the LLVM toolchain, rendering it immune to various security issues other distros are vulnerable to. It has transparent and robust infrastructure, ensuring smooth deployment of packages. We are also developing various new tooling that the whole ecosystem can benefit from, including the Turnstile session tracker. Service management is based around Dinit, a modern, supervising system; we maintain and create a variety of tooling around it, trying to break the existing status quo with systemd, while abandoning legacy approaches. 2023 has seen several major milestones, so I will focus on these, while also giving a short overview so that people unfamiliar with the system don't feel lost. I will also explain how our work benefits the entire Linux ecosystem, as well as beyond.

For the last 3 years, I've been building a complete Linux distribution, Chimera Linux (https://chimera-linux.org) using solely LLVM as its system toolchain - that means Clang, compiler-rt, and libc++, alongside its other tooling. Right now, it is a complete desktop system that is already used by many, with a familiar GNOME interface and thousands of packages, targeting 5 CPU architectures. In this talk I would like to focus on my experiences using the toolchain, what obstacles got in the way, how I dealt with them, the issues that are still left and I would like to see addressed, the many benefits using LLVM gave the project, and overall give the audience an insight into practical deployment of LLVM in a project where it isn't simply a drop-in alternative to GCC.

This talk will show the efforts done in the Open-Source graphics stack for supporting Raspberry Pi devices. Although the talk will focus on the recently launched new Raspberry Pi 5, we will show the improvements done for previous generations of the Raspberry Pi hardware. Raspberry Pi 5 has available FLOSS GPU drivers on product launch, exposing OpenGL-ES 3.1 and Vulkan 1.2. We'll go through the changes needed to enable desktop OpenGL 3.1 on RPi4/5. We will also review the changes done to the kernel driver to expose the RPi5 capabilities and the new GPU stats support for RPi4/5. Finally, we will show the work done to use Wayfire as the default Wayland compositor on the Raspberry Pi OS. - https://www.mesa3d.org/ - https://www.raspberrypi.com/ - https://wayfire.org/ (c) FOSDEM 2024 3 & 4 February 2024 https://fosdem.org/2024/schedule/event/fosdem-2024-2841-graphics-stack-updates-for-raspberry-pi-devices/

This talk will discuss the problems with the traditional vertex processing pipeline and present how mesh shading solves these problems. Instead of processing a fixed set of input vertices, mesh shaders can create an arbitrary topology of vertices and primitives. Mesh shading also includes a new solution for geometry amplification: task shaders. The talk should be scheduled before Timur's talk about implementing mesh shaders in the RADV Mesa driver.

Let's talk about developing AMD display drivers in the DRM subsystem as an external contributor. Part of this work is a trail of breadcrumbs to build documentation. What are those breadcrumbs? How do they help to review, fix, improve and enable features of AMD drivers? How would both sides benefit if those pieces of information were already documented? We are gathering information from anywhere and also bothering experts for input. Ultimately, this presentation focuses on AMD driver development but may fit DRM drivers of any GPU vendors.

There has been a lot of activity in V3DV, the Vulkan driver for Raspberry Pi 4, over the last year: we have significantly reworked our synchronization code, obtained Vulkan 1.1 conformance, implemented Vulkan 1.2 support, continued to work on compiler optimizations and more. In this talk I would like to go through the main development milestones and changes we implemented in the driver as well as discussing some limitations of the underlying hardware platform that have discouraged us from implementing features such as scalar block layout or fp16.

With more memory available, system performance of three Dell devices increased, which can translate to a better user experience Conclusion When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.
