Tour of the Linux Kernel

This is a somewhat incomplete tour of the Linux Kernel, based on Linux 1.0.9 and the 1.1.x development series. Most of it is still relevant.

Device Drivers

The most common Linux kernel programming task is writing a new device driver. The great majority of the code in the kernel is new device drivers; between 1.2.13 and 2.0 the size of the source code more than doubled, and most of that was from adding device drivers.

Filesystems

Adding a filesystem to Linux doesn't have to involve magic...

Linux Memory Management

A few outdated documents, and one completely new one by David Miller on the Linux cache flush architecture.

How System Calls Work on Linux/i86

Although this was written while Linux 0.99.2 was current, it still applies. A few filenames may need updating. find is your friend--just respond with the changes and they will be added.

Other Sources of Information

The KHG is just one collection of information about the Linux kernel. There are others!
