This book cannot teach you about your device, but it gives you a handle on the background you need to make your device work. Presentations. For the two types of device drivers, the Linux kernel offers different APIs. Today, BIOS mainly runs some early diagnostics (power-on-self-test) and then transfers control to the bootloader. Driver samples for specific technologies. For creating and using block devices (disks), a specialized interface defined in linux/genhd.h is used.. Linux as Firmware Tired of reinventing the wheel by implementing drivers for firmware again and again? This short paper tries to introduce all potential driver authors to Linux APIs for PCI device drivers. Although they share a name, the version of dxgkrnl inside of the Linux kernel is a clean room implementation of a Linux GPU driver based on our GPU-PV protocol and doesn’t share anything else in common with its similarly named Windows counterpart.
