Kernel Recipes 2013 - Make your own LED panel

•

1 gefällt mir•1,270 views

This document discusses making an LED panel using a Genesi EfikaMX smarttop board and two LED panels. It involves creating a GStreamer plugin to manage the LED panels with 32x16 pixels each using an RGB video stream. The plugin would take video input and overlay text to display on the LED panels. While the board was previously supported, the current kernel no longer supports it.

A video card is an expansion card which generates a feed of output images to a display device . Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics. At the core of both is the graphics processing unit (GPU), which is the main part that does the actual computations, but should not be confused with the video card as a whole, although "GPU" is often used to refer to video cards.

The IoT is becoming extremely popular keyword in the industries while there are many different interpretations or various definitions. However, one common requirement is that it requires many Sensor devices connected to Linux devices. The user space drivers for GPIO, I2C/SPI and UART sensors in the past were implemented separately from scratch delicately for each product. This will cause significant challenge of software engineering overhead while GPIO, I2C/SPI and UART sensors are dramatically increasing which have to be supported. The IoTDK is one of the library to provide portability of sensors' driver to solve the situation. The talk will includes guide of IoTDK and 96Boards and tutorial of programing I2C and GPIO devices. Targeted audiences are who are interested in IoT sensors or who would like to move from Arduino and Raspberry Pi to modern ARM CPU effectively. This presentation was delivered at LinuxCon Japan 2016 by Akira Tsukamoto.

Wanting to avoid the Android experience, Google developers always aimed to make their Chrome OS Linux kernels as close to mainline as possible. However, when Chromebooks were first created, Google was left with no choice, the mainline kernel, in some subsystems, still did not have all the functionalities needed by Chromebooks. Hence, similarly to Android, Chrome OS had to develop their own out-of-tree code for the kernel and maintain that for a few different kernel versions. Luckily, over the last few years a strong and consistent effort has been happening to bring Chromebook devices closer to mainline. It has led to significant improvements that now make it possible to run mainline on Chrome OS devices. And not only Chromebooks, as these significant strides are also improving Arm-based SOCs and other key components of the rich Chromebook hardware ecosystem. In this talk, we will look at how and why upstream support for Chromebooks improved, the current status of various models, and what we expect in the future. Enric Balletbò i Serra

As the name would suggest, a Non-Maskable Interrupt (NMI) is an interrupt-like feature that is unaffected by the disabling of classic interrupts. In Linux, NMIs are involved in some features such as performance event monitoring, hard-lockup detector, on demand state dumping, etc… Their potential to fire when least expected can fill the most seasoned kernel hackers with dread. AArch64 (aka arm64 in the Linux tree) does not provide architected NMIs, a consequence being that features benefiting from NMIs see their use limited on AArch64. However, the Arm Generic Interrupt Controller (GIC) supports interrupt prioritization and masking, which, among other things, provides a way to control whether or not a set of interrupts can be signaled to a CPU. This talk will cover how, using the GIC interrupt priorities, we provide a way to configure some interrupts to behave in an NMI-like manner on AArch64. We’ll discuss the implementation, some of the complications that ensued and also some of the benefits obtained from it. Julien Thierry

At a rate of almost 9 changes per hour (24/7), the Linux kernel is definitely a scary beast. Bugs are introduced on a daily basis and, through the use of multiple code analyzers, *some* of them are detected and fixed before they hit mainline. Over the course of the last few years, Gustavo has been fixing such bugs and many different issues in every corner of the Linux kernel. Recently, he was in charge of leading the efforts to globally enable -Wimplicit-fallthrough; which appears by default in Linux v5.3. This presentation is a report on all the stuff Gustavo has found and fixed in the kernel with the support of the Core Infrastructure Initiative. Gustavo A.R. Silva

The Linux kernel project includes a huge amount of documentation, but that information has seen little in the way of care over the years. The amount of care has increased significantly recently, though, and things are improving quickly. Listen as the kernel’s documentation maintainer discusses the current state of the kernel’s docs, how we got here, where we’re trying to go, and how you can help. Jonathan Corbet

Modern SoC designs incorporate technologies from numerous vendors, each with their own inconsistent, confusing, undocumented and even contradictory terminology. The result is a mess of acronyms and product names which have a surprising impact on the ability to develop reusable, modular code thanks to the nature of the underlying IP being obscured. This presentation will dive into some of the misnomers plaguing the Arm ecosystem, with the aim of explaining why things are like they are, how they fit together under the architectural umbrella and how you, as a developer, can decipher the baffling ingredients list of your next SoC design!

GNU poke is a new interactive editor for binary data. Not limited to editing basic ntities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them. Once a user has defined a structure for binary data (usually matching some file format) she can search, inspect, create, shuffle and modify abstract entities such as ELF relocations, MP3 tags, DWARF expressions, partition table entries, and so on, with primitives resembling simple editing of bits and bytes. The program comes with a library of already written descriptions (or “pickles” in poke parlance) for many binary formats. GNU poke is useful in many domains. It is very well suited to aid in the development of programs that operate on binary files, such as assemblers and linkers. This was in fact the primary inspiration that brought me to write it: easily injecting flaws into ELF files in order to reproduce toolchain bugs. Also, due to its flexibility, poke is also very useful for reverse engineering, where the real structure of the data being edited is discovered by experiment, interactively. It is also good for the fast development of prototypes for programs like linkers, compressors or filters, and it provides a convenient foundation to write other utilities such as diff and patch tools for binary files. This talk (unlike Gaul) is divided into four parts. First I will introduce the program and show what it does: from simple bits/bytes editing to user-defined structures. Then I will show some of the internals, and how poke is implemented. The third block will cover the way of using Poke to describe user data, which is to say the art of writing “pickles”. The presentation ends with a status of the project, a call for hackers, and a hint at future works. Jose E. Marchesi

Operating system distributors often face challenges that are somewhat different from that of upstream kernel developers. For instance, some kernel updates often need to stay at least binary compatible with modules that might be “out of tree” for some time. In that context, being able to automatically detect and analyze changes to the binary interface exposed by the kernel to its module does have some noticeable value. The Libabigail framework is capable of analyzing ELF binaries along with their accompanying debug info in the DWARF format, detect and report changes in types, functions, variables and ELF symbols. It has historically supported that for user space shared libraries and application so we worked to make it understand the Linux kernel binaries. In this presentation, we are going to present the current support of ABI analysis for Linux Kernel binaries, the challenges we face, how we address them and the plans we have for the future.

Different upgrade and update strategies exist when it comes to embedded Linux system. If at development time none of these strategies have been chosen, adding them afterwards can be tedious task. Even harder it gets when the system is already deployed in the field and only accessible via a 3G connection. This talk is a developer experience of putting in place exactly that. Giving a return of experience on one way of doing it on a system running Barebox and a Yocto-based distribution. Patrick Boettcher

Traditionally graphics drivers were one of the last hold-outs of proprietary software in an embedded Linux system. This situation is changing with open-source graphics drivers showing up for almost all of the graphics acceleration peripherals on the market right now. This talk will show how open-source graphics drivers are making embedded systems less special, as well as trying to provide an overview of the Linux graphics stack, de-mystifying what is often seen as black magic GPU stuff from outside observers.

The I2C subsystem is not the shiniest part of the Linux Kernel. For embedded devices, though, it is one of the many puzzle pieces which just have to work. Wolfram Sang has the experience of maintaining this subsystem for nearly 7 years now. This talk gives a short overview of how maintaining works in general and specifically in this subsystem. But mainly, it will highlight noteworthy points in the timeline and lessons learnt from that. It will present trends, not so much regarding I2C but more the Linux Kernel and the embedded ecosystem in general. And of course, there will be plenty of anecdotes and bits from behind the scenes for your entertainment. Wolfram Sang

ITRenew is selling recertified OCP servers under the Sesame brand, those servers come either with their original UEFI BIOS or with LinuxBoot. The LinuxBoot project is pushing the Linux kernel inside bios flash and using userland programs as bootloader. To achieve quality on our software stack, as any project, we need to test it. Traditional BIOS are tested by hand, this is 2019 we need to do it automatically! We already presented the hardware setup behind the LinuxBoot CI, this talk will focus on the software. We use u-root for our userland bootloader; this software is written in Go so we naturally choose to use Go for our testing too. We will present how we are using and extending the Go native test framework `go test` for testing embedded systems (serial console) and improving the report format for integration to a CI.

About 60% of the Linux kernel source tree is devoted to drivers for a large variety of supported hardware components. Especially in the embedded world, the number of different SoC families, versions, and revisions, integrating a myriad of “IP cores”, keeps on growing. In this presentation, Geert will explain how to match drivers against hardware, and how to support a wide variety of (dis)similar devices, without turning platform and driver code into an entangled bowl of spaghetti.tra Starting with a brief history of driver matching in Linux, he will fast-forward to device-tree based matching. He will discuss ways to handle slight variations of the same hardware devices, and different SoC revisions, each with their own quirks and bugs. Finally, Geert will show best practices for evolving device drivers in a maintainable way, based on his experiences as an embedded Linux kernel developer and maintainer. Geert Uytterhoeven

Buildroot is a popular and easy to use embedded Linux build system. It generates, in few minutes, lightweight and customized Linux systems, including the cross-compilation toolchain, kernel and bootloader images, as well as a wide variety of userspace libraries and programs. This talk is about the integration of LLVM/clang into Buildroot. In 2018, Valentin Korenblit, supervised by Romain Naour, worked on this topic during his internship at Smile ECS. After a short introduction about llvm/clang and Buildroot, this talk will go through the numerous issues discovered while adding llvm/clang componants and how these issues were fixed. Romain will also detail the work in progress and the work to be done based on llvm/clang libraries (OpenCL, Compiler-rt, BCC. Chromium, ldd). Romain Naour

This talk introduces JTAG debugging capabilities, both for debugging hardware and software. Marek first explains what the JTAG stands for and explains the operation of the JTAG state machine. This is followed by an introduction to free software JTAG tools, OpenOCD and urJTAG. Marek shortly explains how to debug software using those tools and how that ties into the JTAG state machine. However, JTAG was designed for testing hardware. Marek explains what boundary scan testing (BST) is, what are BSDL files and their format, and practically demonstrates how to blink an LED using BST and only free software tools. Marek Vasut

PipeWire is an open source project that aims to greatly improve audio and video handling under Linux. Utilising a fresh design, it bridges use cases that have been previously addressed by different tools – or not addressed at all -, providing ground for building complex, yet secure and efficient, multimedia systems. In this talk, Julien is going to present the PipeWire project and the concepts that make up its design. In addition, he is going to give an update of the current and future work going on around PipeWire, both upstream and in Automotive Grade Linux, an early adopter that Julien is actively working on.

Ftrace’s most powerful feature is the function tracer (and function graph tracer which is built from it). But to have this enabled on production systems, it had to have its overhead be negligible when disabled. As the function tracer uses gcc’s profiling mechanism, which adds a call to “mcount” (or more recently fentry, don’t worry if you don’t know what this is, it will all be explained) at the start of almost all functions, it had to do something about the overhead that causes. The solution was to turn those calls into “nops” (an instruction that the CPU simply ignores). But this was no easy feat. It took a lot to come up with a solution (and also turning a few network cards into bricks). This talk will explain the history of how ftrace came about implementing the function tracer, and brought with it the possibility of static branches and soon static calls! Steven Rostedt

Suricata is a network threat detection engine using network packets capture to reconstruct the traffic till the application layer and find threats on the network using rules that define behavior to detect. This task is really CPU intensive and discarding non interesting traffic is a solution to enable a scaling of Suricata to 40gbps and other. This talk will present the latest evolution of Suricata that knows uses eBPF and XDP to bypass traffic. Suricata 5.0 is supporting the hardware XDP to provide ypass with network card such as Netronome. It also takes advantage of pinned maps to get persistance of the bypassed flows. This talk will cover the different usage of XDP and eBPF in Suricata and shows how it impact performance and usability. If development time permit, the talk will also cover AF_XDP and the impact on this new capture method on Suricata. Eric Leblond

System memory configuration is a transparent operation nowadays, something that we all came to expect to just work out of the box. Still, it does happen behind the scenes every single time we boot our computers. This requires the cooperation of hardware components on the mainboard and on memory modules themselves, as well as firmware code to drive these. While it is possible to just let it happen, having a deeper understanding of how it works makes it possible to access valuable information from the operating system at run-time. I will take you through the history of system memory configuration from the mid 70s to now. We will explore the different types of memory modules, how their configuration data is stored and how the firmware can access them. We will see which problems had to be solved along the way and how they were solved. Lastly we will see how Linux supports reading the memory configuration information and what you can do with that information. Jean Delvare
