My take on people's amazing judgmental power, the funny and the not so funny side.

This post explains how to create a userspace C program as a Buildroot package that tests an existing kernel module. It details steps including creating package directories and files, defining dependencies, and populating configuration files. The process includes setting installation commands and proper source code structure for successful compilation and deployment.

How to add/compile a kernel module as a new buildroot package

The content explains how to integrate an external kernel device driver as a new package in the Buildroot system, named "xyz." It involves creating a directory for the package and two essential files, Config.in and xyz.mk, which define package configuration and build instructions. The Config.in file sets up package options, while xyz.mk specifies module version, site, license, and build commands. Modifications are required in the main Buildroot Config.in file to include the new package, making it visible in the menuconfig. Finally, it outlines necessary adjustments in the source code's top-level Makefile for successful integration.

How to run an external program from a python script

This is a demonstration how a python script can be used to automate the running of an external program which takes data file as input. The data file can be spread over differnet folders in the machine. The script goes to the data file location, extracts the name of each file in the folder and then passes the data file to the external binary.

Efficient Source Code Management Using Vim and Cscope

The author emphasizes that Vim, especially when used with Cscope and Ctags, is invaluable for navigating large Linux codebases. A guide is provided with steps for effective setup, including database location, exclusion of unnecessary directories, and enabling Cscope navigation in Vim. The focus is on enhancing developer productivity and code management.
