I wrote a small shell script™ to automate building new Linux Kernels. I use this to build new kernels on my Debian systems:
#!/usr/bin/env bash
WORKSPACE='/home/gd/workspace'
LINUX="${WORKSPACE}/linux"
find "${WORKSPACE}" -type f \( -name 'linux-*deb' -o -name 'linux-upstream*' \) -mtime -3 -exec rm {} \;
Debug a Linux Kernel in QEMU
Here's a how-to for building a recent Linux kernel on your Debian GNU/Linux box: You will need to do all this as root. It's serious business building new Linux kernels :) su - The dash after the su command makes it behave as if you had logged in as root directly, a full login environment is applied. Make sure you have the required tools and libraries installed: apt install build-essential initramfs-tools procps libncurses5-dev fakeroot git-core screen zlib1g-dev flex bison bc libelf-dev:native libssl-dev:native Use git to clone Linus' latest git repo: cd /usr/src git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git This will take a long time: Cloning into 'linux'... remote: Counting objects: 2725713, done. remote: Compressing objects: 100% (412816/412816), done. remote: Total 2725713 (delta 2286272), reused 2725359 (delta 2285962) Receiving objects: 100% (2725713/2725713), 559.28 MiB | 3.30 MiB/s, done.

Every day I see new Linux Kernel hackers fail at their first patch submission. I'm not an expert, but I've learned how the process works and most importantly I've learned how to avoid irritating Linux Kernel maintainers. The "maintainers" are the gate keepers to the Linux Kernel. If you piss them off you will never land any patches into the Linux Kernel. All Linux Kernel development takes place in the open and hundreds (thousands?) of Linux Kernel developers will see and possibly read your patch submissions. You will want to make every effort to submit the best possible patch you can. That's where I come in. If you follow my guide there's a better than average chance you will actually land your patch into the Linux Kernel. For a beginner I recommend working on the drivers/staging tree maintained by Greg Kroah-Hartman. Clone Greg KH's staging tree: > git clone git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git This will take a while. After that you need to checkou
I don't play the lottery but I find random number generators and the Linux Kernel interesting so I wrote a simple Linux Kernel module that does a PowerballTM "quick pick". You can download it from GitHub: https://github.com/gdonald/linux-kernel-powerball-module
