  • Debugging Kernel Problems
    Debugging Kernel Problems by GregLehey Edition for AsiaBSDCon 2004 Taipei, 13 March 2004 Debugging Kernel Problems by GregLehey([email protected]) Copyright © 1995-2004 GregLehey 3Debugging Kernel Problems Preface Debugging kernel problems is a black art. Not manypeople do it, and documentation is rare, in- accurate and incomplete. This document is no exception: faced with the choice of accuracyand completeness, I chose to attempt the latter.Asusual, time was the limiting factor,and this draft is still in beta status. This is a typical situation for the whole topic of kernel debugging: building debug tools and documentation is expensive,and the people who write them are also the people who use them, so there'satendencytobuild as much of the tool as necessary to do the job at hand. If the tool is well-written, it will be reusable by the next person who looks at a particular area; if not, it might fall into disuse. Consider this book a starting point for your own develop- ment of debugging tools, and remember: more than anywhere else, this is an area with ``some as- sembly required''. Debugging Kernel Problems 4 1 Introduction Operating systems fail. All operating systems contain bugs, and theywill sometimes cause the system to behave incorrectly.The BSD kernels are no exception. Compared to most other oper- ating systems, both free and commercial, the BSD kernels offer a large number of debugging tools. This tutorial examines the options available both to the experienced end user and also to the developer. In this tutorial, we’ll look at the following topics: • Howand whykernels fail.

  • Fixing USB Autosuspend Serge Y
    Fixing USB Autosuspend Serge Y. Stroobandt Copyright 2015–2017, licensed under Creative Commons BY-NC-SA Problem The Linux kernel automatically suspends USB de- vices when there is driver support and the devices are not in use.1 This saves quite a bit of power. How- ever, some USB devices are not compatible with USB autosuspend and will misbehave at some point. Af- fected devices are most commonly USB mice and keyboards.2 Personally,I had only one Microsoft™ Wheel Mouse Optical affected, despitewning o other mod- els of the same brand. In essence, this is not really a USB hardware problem, but perhaps more a Lin- ux problem. The actual fault lies with a misinterpretation of the eXtensible Host Controller Interface (xHCI) specification. This issueviousl pre y did not exist with the older Enhanced Host Controller Interface (EHCI) specification. A «Sharp» explanation is available online.3 The Linux kernel patch for this problem will probably one day automatically trickle in downstream and onto my affectedubuntu X LTS 14.04 system. Nonetheless, with a crashing computer mouse at hand, things cannot wait. However, patching my current 3.13.0-35-generic x86_64 kernel is out of the question! We will rather grab this opportunity to learn a bit about writing rules for udev , the device manager for the Linux kernel. I am writing “for the Linux kernel”, because udev executes entirely in user space. Identify the device First, one needs to properly identify the affected USBvice de by its vendor and product ID. Run the following command and look for the device description.

  • Appendix B Development Tools
    Appendix B Development Tools Problem Statement Although more proprietary packages are available, there are abundant open source packages, giving its users unprecedented flexibility and freedom of choice, that most users can find an application that exactly meets their needs. However, it is also this pool of choices that drive individuals to share a wide range of preferences and biases. As a result, Linux/Open source packages (and softeware in general) is flooded with religious wars over programming languages, editors, licences, etc. Some are worthwhile debates, others are meaningless flamewars. Throughout Appendix B and next chapter, Appendix C, we intend to summarize a few essential tools (from our point of view) that may help readers to know the aspects and how-to of (1) development tools including programming, debugging, and maintaining, and (2) network experiment tools including name-addressing, perimeter probing, traffic-monitoring, benchmarking, simulating/emulating, and finally hacking. Section B.1 guides readers to begin the developing journey with programming tools. A good first step would be writing the first piece of codes using a Visual Improved (vim) text editor. Then compiling it to binary executables with GNU C compiler (gcc), and furthermore offloading some repetitive compiling steps to the make utility. The old 80/20 rule still works on programming where 80% of your codes come from 20% of your efforts leaving 80% of your efforts go buggy about your program. Therefore you would need some debugging tools as dicussed in Section 1.2. including source-level debugging, GNU Debugger (gdb), or a GUI fasion approach, Data Display Debugger (ddd), and debug the kernel itself using remote Kernel GNU Debugger (kgdb).
