When no technical documentation is available, an understanding of the underlying hardware is often gained by clean-room reverse engineering. These problems, which affect system stability, security and performance, are the main reason for the independent development of free and open-source drivers. Binary drivers used in the context of operating systems that are prone to ongoing development and change (such as Linux) create problems for end users and package maintainers. The driver is made up of a compiler, a rendering API, and software which manages access to the graphics hardware.ĭrivers without freely (and legally) -available source code are commonly known as binary drivers. Most free and open-source graphics device drivers are developed by the Mesa project. They may also control output to the display if the display driver is part of the graphics hardware. Graphics device drivers are written for specific hardware to work within a specific operating system kernel and to support a range of APIs used by applications to access the graphics hardware. The rendered results are stored in a framebuffer, whose content is scanned by the display controller and sent to the screen.Ī free and open-source graphics device driver is a software stack which controls computer-graphics hardware and supports graphics-rendering application programming interfaces (APIs) and is released under a free and open-source software license. Data and instructions are sent to the GPU for processing.
