Kernel Development

Note

TL;DR

• Articles on mainline Linux kernel development — writing and porting device drivers, bringing up hardware subsystems, and the debugging method that gets a driver from “it probes” to “it produces correct output”.

• Focused on the parts that are not in the documentation: how a failure actually presents itself, and what it turned out to mean.

Contents:

• Porting a Stateless H.264 Encoder: Rockchip VEPU2 and v4l2-h264-enc
