  • The Linux 2.4 Kernel's Startup Procedure

    The Linux 2.4 Kernel's Startup Procedure

    The Linux 2.4 Kernel’s Startup Procedure William Gatliff 1. Overview This paper describes the Linux 2.4 kernel’s startup process, from the moment the kernel gets control of the host hardware until the kernel is ready to run user processes. Along the way, it covers the programming environment Linux expects at boot time, how peripherals are initialized, and how Linux knows what to do next. 2. The Big Picture Figure 1 is a function call diagram that describes the kernel’s startup procedure. As it shows, kernel initialization proceeds through a number of distinct phases, starting with basic hardware initialization and ending with the kernel’s launching of /bin/init and other user programs. The dashed line in the figure shows that init() is invoked as a kernel thread, not as a function call. Figure 1. The kernel’s startup procedure. Figure 2 is a flowchart that provides an even more generalized picture of the boot process, starting with the bootloader extracting and running the kernel image, and ending with running user programs. Figure 2. The kernel’s startup procedure, in less detail. The following sections describe each of these function calls, including examples taken from the Hitachi SH7750/Sega Dreamcast version of the kernel. 3. In The Beginning... The Linux boot process begins with the kernel’s _stext function, located in arch/<host>/kernel/head.S. This function is called _start in some versions. Interrupts are disabled at this point, and only minimal memory accesses may be possible depending on the capabilities of the host hardware.

    Collabkit – a Multi-User Multicast Collaboration System Based on VNC

    Humboldt-Universität zu Berlin Institut für Informatik Lehrstuhl für Rechnerorganisation und Kommunikation Diplomarbeit CollabKit – A Multi-User Multicast Collaboration System based on VNC Christian Beier 19. April 2011 Gutachter Prof. Dr. Miroslaw Malek Prof. Dr. Jens-Peter Redlich Betreuer Peter Ibach <[email protected]> Abstract Computer-supported real-time collaboration systems offer functionality to let two or more users work together at the same time, allowing them to jointly create, modify and exchange electronic documents, use applications, and share information location-independently and in real-time. For these reasons, such collaboration systems are often used in professional and academic contexts by teams of knowledge workers located in different places. But also when used as computer-supported learning environments – electronic classrooms – these systems prove useful by offering interactive multi-media teaching possibilities and allowing for location-independent collaborative learning. Commonly, computer-supported real-time collaboration systems are realised using remote desktop technology or are implemented as web applications. However, none of the examined existing commercial and academic solutions were found to support concurrent multi-user interaction in an application-independent manner. When used in low-throughput shared-medium computer networks such as WLANs or cellular networks, most of the investigated systems furthermore do not scale well with an increasing number of users, making them unsuitable for multi-user collaboration of a high number of participants in such environments. For these reasons this work focuses on the design of a collaboration system that supports concurrent multi-user interaction with standard desktop applications and is able to serve a high number of users on low-throughput shared-medium computer networks by making use of multicast data transmission.
  • The Linux Startup Process

    The Linux Startup Process

    The Linux startup process Jerry Feldman <[email protected]> The Linux Expertise Center Hewlett-Packard Company Document produced via OpenOffice.org Overview ● The Linux boot process – GRUB. This is the default for X86/Linux – LILO – Other boot loaders ● The Linux Operating modes – Single-user mode – Multi-user mode. ● Run Levels – What are run levels – What are the Linux standard run levels – How Linux manages run levels 2 The Linux Boot process ● The PC boot process is a 3-stage boot process that begins with the BIOS executing a short program that is stored in the Master Boot Record (MBR) of the first physical drive. Since this stage 1 boot loader needs to fit in the MBR, it is limited to 512 bytes and is normally written in assembly language. There are a number of boot loaders that can load Linux. ● GRUB and LILO are the most commonly used ones on X86 hardware. ® ® ● EFI is used on the Intel Itanium family. 3 The GRand Unified Bootloader The GRand Unified Bootloader (GRUB) is default boot loader on most distributions today. It has the capability to load a number of different operating systems. 1.The stage 1 boot resides in the MBR and contains the sector number of the stage 2 boot that is usually located in the /boot/grub directory on Linux. 2.The stage 2 boot loader presents a boot menu to the user based on /boot/grub/grub.conf or menu.lst. This contains a boot script. It is the stage2 loader actually loads the Linux kernel or 4 other OS.

    Implementing Full Device Cloning on the NVIDIA Jetson Platform March 2, 2018 Calvin Chen Linh Hoang Connor Smith Advisor: Professor Mark Claypool Sponsor - Mentor : NVIDIA - Jimmy Zhang Abstract NVIDIA’s Linux For Tegra development team provides support for many tools which exist on the Jetson-TX2 embedded AI computing device. While tools to clone the user partitions of the Jetson-TX2 exist, no tool exists to fully backup and restore all of the partitions and configurations of these boards. The goal of this project was to develop a tool that allows a user to create a complete clone of the Jetson-TX2 board’s partitions and their contents. We developed a series of bash scripts that fully backup the partitions and configurations of one Jetson-TX2 board and restore them onto another board of the same type. 1 Table of Contents Abstract 1 Table of Contents 2 1 Introduction 3 2 Background 5 2.1 Preliminary Research 5 2.1.1 UEFI Booting and Flashing 5 2.1.2 Tegra Linux Driver Package 8 2.1.3 Network File System 8 2.1.4 Jetson TX2 Bootloader 10 2.2 Linux Terminology, RCM boot and Initial ramdisk 12 2.2.1 Linux Terminology 12 2.2.2 USB Recovery Mode (RCM) Boot 13 2.2.3 Initial Ramdisk 14 2.3 Associated Technologies 15 2.3.1 Linux tools 15 2.3.2 Serial Console 16 3 Methodology 17 4 Product 20 4.1 Backup Script 20 4.2 Restore Script 22 4.3 Initial ramdisk (initrd) 24 4.4 Script Development Guidelines 26 4.4.1 Use Case 26 4.4.2 Integrity 26 4.4.3 Performance 27 5 Future Work 29 6 Conclusions 30 7 Bibliography 31 2 1 Introduction The Jetson-TX2 is a low power, high performance embedded artificial intelligence supercomputer utilized in many modern technologies.

    Best of a decade on Opensource.com 2010–2019 In celebration of our 10-year anniversary Opensource.com/yearbook FROM THE EDITOR ............................. FROM THE EDITOR ............................. Dear reader, As we celebrate 10 years of publishing, our focus is on the people from all over the globe, in various roles, from diverse backgrounds, who have helped us explore the multitude of ways in which open source can improve our lives—from technology and programming to farming and design, and so much more. We are celebrating you because we’ve learned that growing this unique storytelling site demands that we do one thing better than all the rest: listen to and talk with our readers and writers. Over the years, we’ve gotten better at it. We regularly hold meetings where we review how articles performed with readers from the week before and discuss why we think that’s so. We brainstorm and pitch new and exciting article ideas to our writer community on a weekly basis. And we build and nurture close relationships with many writers who publish articles for us every month. As an editor, I never would have imagined my biggest responsibility would be community management and relationship building over copy editing and calendar planning. I’m so grateful for this because it’s made being a part of Opensource.com a deeply rewarding experience. In December, we closed out a decade of publishing by reaching a new, all-time record of over 2 million reads and over 1 million readers. For us, this validates and affirms the value we’ve learned to place on relationships with people in a world swirling with metrics and trends.
