Containers with systemd-nspawn

This Presentation contains information about os level virtualization and Containers internals. It has used other material on slide share which is referenced in Notes of PPT

U-Boot is an open source boot loader that initializes hardware and loads operating systems. It supports many CPUs and boards. The boot process involves a pre-relocation phase where U-Boot initializes hardware and copies itself to RAM, and a post-relocation phase where it finishes hardware initialization and loads the kernel or operating system. Debugging can be done before and after relocation by setting breakpoints and examining memory.

U-Boot project has evolved in the time span of over 17 years and so as its complexity and its uses. This has made it a daunting task in getting started with its development and uses. This talk will address all these issues start with overview, features, efforts created by community and future plans. The U-Boot project has evolved in the time span of over 17 years and so as its complexity and its uses. This has made it a daunting task in getting started with its development and uses. This talk will address all these issues and share development efforts created by the U-Boot community. In this talk Jagan Teki(Maintainer for Allwinner SoC, SPI, SPI FLASH Subsystems) will introduce U-Boot from scratch with a brief overview of U-Boot history, U-Boot Proper, SPL, TPL, Build process and Startup sequence. He will talk about other preliminaries such as Image booting, Falcon Mode, Secure Boot and U-Boot features like device tree, device overlays, driver model and DFU, etc. Once giving enough introduction, he will also talk about steps to port U-Boot to new hardware with a demo, along with U-Boot testing process. Finally, he will address and review ongoing development work, issues and future development regarding U-Boot.

The document describes hypervisors and their role in virtualization. It discusses how a hypervisor sits between virtual machines and hardware to provide an isolated environment for each VM. It also compares different types of hypervisors, including describing how early hypervisors used full virtualization through trap-and-emulate to virtualize privileged instructions. The document then discusses the design conditions for a hypervisor based on Popek and Goldberg's virtualization theorem, including how the hypervisor must provide equivalence, performance, and resource control for virtual machines.

ContainerD is a daemon that controls the runC runtime to execute and manage containers according to the OCI specification. It has a gRPC API and a low-level CLI (ctr) for debugging. ContainerD is designed to be embedded in larger systems rather than directly used by end-users. It focuses on container execution, images, storage, and networking.

Gives the introduction about Internet Small Computer System Interface, Its usage, working of iSCSI and how to discover Initiator and target for iSCSI.

This presentation gives introduction to kernel module programming with sample kernel module. It helps to start with kernel programming and how it can be used to develop various types of device drivers.

This document discusses the Peripheral Component Interconnect (PCI) driver subsystem in Linux. It covers PCI architecture basics, the kernel PCI subsystem, registering PCI drivers, probing PCI devices, accessing PCI configuration and I/O spaces, handling DMA, and provides code examples and APIs for writing PCI device drivers.

This document provides an overview of the steps to port the U-boot bootloader to a new SoC using the NDS32 architecture as an example. It describes the directory structure of U-boot and key files related to the architecture, board, configuration, and device drivers. The document outlines where to define SoC hardware addresses, initialize board-specific peripherals, configure options, and implement device drivers to support the new SoC and board.

This document discusses the key components and architecture of the Linux kernel. It begins by defining the kernel as the central module of an operating system that loads first and remains in memory, providing essential services. It then describes the major subsystems of Linux, including process management, memory management, virtual file systems, network stacks, and device drivers. It concludes that the modular design of the Linux kernel has supported its growth and success through independent and extensible development of these subsystems.

Docker allows deploying applications easily across various environments by packaging them along with their dependencies into standardized units called containers. It provides isolation and security while allowing higher density and lower overhead than virtual machines. Core OS and Mesos both integrate with Docker to deploy containers on clusters of machines for scalability and high availability.
