Microkernel Mechanisms for Improving the Trustworthiness of Commodity Hardware
Microkernel Mechanisms for Improving the Trustworthiness of Commodity Hardware Yanyan Shen Submitted in fulﬁlment of the requirements for the degree of Doctor of Philosophy School of Computer Science and Engineering Faculty of Engineering March 2019 Thesis/Dissertation Sheet Surname/Family Name : Shen Given Name/s : Yanyan Abbreviation for degree as give in the University calendar : PhD Faculty : Faculty of Engineering School : School of Computer Science and Engineering Microkernel Mechanisms for Improving the Trustworthiness of Commodity Thesis Title : Hardware Abstract 350 words maximum: (PLEASE TYPE) The thesis presents microkernel-based software-implemented mechanisms for improving the trustworthiness of computer systems based on commercial off-the-shelf (COTS) hardware that can malfunction when the hardware is impacted by transient hardware faults. The hardware anomalies, if undetected, can cause data corruptions, system crashes, and security vulnerabilities, significantly undermining system dependability. Specifically, we adopt the single event upset (SEU) fault model and address transient CPU or memory faults. We take advantage of the functional correctness and isolation guarantee provided by the formally verified seL4 microkernel and hardware redundancy provided by multicore processors, design the redundant co-execution (RCoE) architecture that replicates a whole software system (including the microkernel) onto different CPU cores, and implement two variants, loosely-coupled redundant co-execution (LC-RCoE) and closely-coupled redundant co-execution (CC-RCoE), for the ARM and x86 architectures. RCoE treats each replica of the software system as a state machine and ensures that the replicas start from the same initial state, observe consistent inputs, perform equivalent state transitions, and thus produce consistent outputs during error-free executions.

Chapter 1: Linux Operating System
CHAPTER 1: LINUX OPERATING SYSTEM A bit of history What is Linux? A short answer to this question is "a computer operating system based on Linux kernel and GNU tools and libraries". In order to understand what Linux is, first we need to know different concepts such as Linux, kernel, and GNU. Formally, Linux is not an operating system. It's just a software component working as a bridge between applications and the data processing done by the hardware. Because of this fact, the kernel is the core component of an operating system. First Linux kernel was written by Linus Torvalds in 1991. Usually, the term Linux is used to refer to a whole operating system based on the kernel. However, an operating system needs more components to be complete. At this point, there are a number of operating system based on Linux kernel, plus a set of tools provided by the GNU open source project. What are GNU tools? Well, first of all we should learn about the GNU project. Basically, this is an open source project started by Richard Stallman with the goal of building a set of software components and tools to avoid the use of any software that is not free. Now that we've learned about Linux, kernel, and GNU, we can define a distribution as a composition of Linux kernel and GNU tools and other useful software. We've just mentioned a new concept—distribution. Have you heard about Linux mascot: Tux the penguin Ubuntu, Fedora, or Debian? These three are examples of Linux distributions.

Popcorn Linux: Enabling Efficient Inter-Core Communication in a Linux-Based Multikernel Operating System
Popcorn Linux: enabling efficient inter-core communication in a Linux-based multikernel operating system Benjamin H. Shelton Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in Computer Engineering Binoy Ravindran Christopher Jules White Paul E. Plassman May 2, 2013 Blacksburg, Virginia Keywords: Operating systems, multikernel, high-performance computing, heterogeneous computing, multicore, scalability, message passing Copyright 2013, Benjamin H. Shelton Popcorn Linux: enabling efficient inter-core communication in a Linux-based multikernel operating system Benjamin H. Shelton (ABSTRACT) As manufacturers introduce new machines with more cores, more NUMA-like architectures, and more tightly integrated heterogeneous processors, the traditional abstraction of a mono- lithic OS running on a SMP system is encountering new challenges. One proposed path forward is the multikernel operating system. Previous efforts have shown promising results both in scalability and in support for heterogeneity. However, one effort’s source code is not freely available (FOS), and the other effort is not self-hosting and does not support a majority of existing applications (Barrelfish). In this thesis, we present Popcorn, a Linux-based multikernel operating system. While Popcorn was a group effort, the boot layer code and the memory partitioning code are the authors work, and we present them in detail here. To our knowledge, we are the first to support multiple instances of the Linux kernel on a 64-bit x86 machine and to support more than 4 kernels running simultaneously. We demonstrate that existing subsystems within Linux can be leveraged to meet the design goals of a multikernel OS.

You can install Ubuntu Mate on your old laptop and keep at the same time Windows XP too, if you like XP. Or you can buy a tiny new laptop about 200-300 €/$ and change Windows 10 to Ubuntu. It works! I have made both about three years ago, and I haven't used Windows since then. My own laptop is cheap HP Stream 4 MB/32 GB. When I was studying Ubuntu, I noticed that simple beginner's guide books were not available. So, I did a guide book. I also created a website and named it www.ubuntutor.com. It currently includes Ubuntu 16.04 and 18.04 tutorials. And this guide is third one.
