Chapter 3 – UEFI Driver Model

Things should be made as simple as possible–but no simpler.

—Albert Einstein

The Unified Extensible Firmware Interface (UEFI) provides a driver model for support of devices that attach to today’s industry-standard buses, such as Peripheral Component Interconnect (PCI) and Universal Serial Bus (USB), and architectures of tomorrow. The UEFI Driver Model is intended to simplify the design and implementation of device drivers, and produce small executable image sizes. As a result, some complexity has been moved into bus drivers and to a greater extent into common firmware services. A device driver needs to produce a Driver Binding Protocol on the same image handle on which the driver was loaded. It then waits for the ...
