The kernel embeds device drivers for every peripheral in the computer system.Device drivers have seven times the bug rate of other kernel code.The display driver and the video decoder are inherent parts of the graphics card: hardware designed to assist in the calculations necessary for the decoding of video streams.As the market for PC hardware has dwindled, it seems unlikely that new competitors will enter this market and it is unclear how much more knowledge one company could gain by seeing the source code of other companies' drivers. The functional blocks (the application-specific integrated circuit display driver, 2- and 3D acceleration and video decoding and encoding) are separate semiconductor intellectual property (SIP) blocks on the chip, since hardware devices vary substantially; some portable media players require a display driver that accelerates video decoding, but do not require 3D acceleration.Solutions to bugs in the driver cannot be shared, significantly reducing the utility of such drivers in comparison to free and open-source drivers.
ADF has not been accepted into mainline, but a different set of solutions addressing the same problems (known as atomic mode setting) is under development.Additional problems are the Android-specific augmentations to the Linux kernel which have not been accepted in mainline, such as the Atomic Display Framework (ADF).ADF is a feature of 3.10 AOSP kernels which provides a dma-buf-centric framework between Android's hwcomposer HAL and the kernel driver.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.These problems, which affect system stability, security and performance, are the main reason for the independent development of free and open-source drivers.
