Mixed Up Devices, Sound/Network Cards Changing Order Each Boot - Udev - ArchWiki
udev is a userspace system that enables the operating system administrator to register userspace handlers for events. The events received by udev's daemon are mainly generated by the (Linux) kernel in response to physical events relating to peripheral devices. As such, udev's main purpose is to act upon peripheral detection and hot-plugging, including actions that return control to the kernel, e.g

Building a custom kernel - Fedora Project Wiki
dnf versus yum As of Fedora 22[1] dnf has replaced yum as the default package manager. In the event you are building a kernel for an older system you will either have to install dnf or substitute yum for dnf and/or yumdownloader from the yum-utils package. Building a Kernel from the Fedora source tree Make sure you have installed all dependencies $ fedpkg clone kernel you will likely need to check
Package Maintenance Guide
This page provides some basic instructions for day-to-day usage of the git-based package maintenance system for Fedora. It is intended primarily for new and current Fedora package maintainers, but does briefly cover anonymous read-only use of the system. It is not a guide to RPM packaging per se. Some pre-existing knowledge of git may be useful, but is not a pre-requisite. In fact, Fedora packagin
Saving power with Linux on Intel hardware
Home | PowerTOP | Download | Tips & Tricks | Success Stories | FAQ | Discuss Power usage is a hot topic for computer users everywhere. For some, it's a matter of how long a laptop lasts without being plugged in. For others, it's controlling the temperature of hundreds of systems within a datacenter. For all of us, it's about keeping the electricity bill under control and being kind to the environm

Receive packet steering [LWN.net]
Contemporary networking hardware can move a lot of packets, to the point that the host computer can have a hard time keeping up. In recent years, CPU speeds have stopped increasing, but the number of CPU cores is growing. The implication is clear: if the networking stack is to be able to keep up with the hardware, smarter processing (such as generic receive offload) will not be enough; the system

vflare: Linux kernel workflow with Git
You worked on some part of Linux kernel. It works great. Now, how to generate the patch series and send it out for review? For this, I always used to generate diffs, create a set of draft mails (one for each patch) in KMail or Thunderbird, and send all these mails one-by-one. This workflow quickly became a big headache. Then I learned Git (and some related tools) to do all this from command line a
