Hardware abstraction layer - Wikipedia, the free encyclopedia
A hardware abstraction layer ( HAL ) is an abstraction layer, implemented in software, between the physical hardware of a computer and the software that runs on that computer. Its function is to h...

One tricky design decision is the amount of abstraction to aim for. Too little, and the system is not flexible enough; too much and HAL design is needlessly complicated for simple hardware. The present design tries to err on the side of too little abstraction. ... This SWI provides access to the hardware layer.

A hardware abstraction layer is a component of an operating system that functions something like an API. ... (In strict technical architecture, hardware abstraction layers reside at the device level, a layer below the standard API level.) It allows programmers to write applications and game titles with all the...

My proposal is that the hardware abstraction layer be a shared library API. The API would work in terms of Device objects. On Linux a Device object often maps to a kernel device, but may also map to some entirely userspace devices (printers are typically all userspace, and may even be network devices).
