In the middle: the FOSS stack, composed out of DRM & KMS driver, libDRM and Mesa 3D.Right side: Proprietary drivers: Kernel BLOB and User-space components. nouveau (/ n uː ˈ v oʊ /) is a free and open-source graphics device driver for Nvidia video cards and the Tegra family of SoCs written by independent software engineers, with minor help from Nvidia employees.
Device Dependent X (DDX), another 2D graphics device driver for X.Org Server; The DRM is kernel-specific. A VESA driver is generally available for any operating system. The VESA driver supports most graphics cards without acceleration and at display resolutions limited to a set programmed in the Video BIOS by the manufacturer. [15]
Each GPU detected by DRM is referred to as a DRM device, and a device file /dev/dri/cardX (where X is a sequential number) is created to interface with it. [8] [9] User-space programs that want to talk to the GPU must open this file and use ioctl calls to communicate with DRM. Different ioctls correspond to different functions of the DRM API.
Display Diagnostics, with Kernel mode device driver interface changes to allow the driver for a display controller to report diagnostic events to the operating system. Shared graphics power components , allowing non-graphics drivers to participate in the power management of a graphics device.
The GeForce 6 series (codename NV40) is the sixth generation of Nvidia's GeForce line of graphics processing units.Launched on April 14, 2004, the GeForce 6 family introduced PureVideo post-processing for video, SLI technology, and Shader Model 3.0 support (compliant with Microsoft DirectX 9.0c specification and OpenGL 2.0).
www.nvidia.com /en-us /drivers /nvidia-system-tools-6 _08-driver / NVIDIA System Tools (previously called nTune ) is a discontinued collection of utilities for accessing, monitoring, and adjusting system components, including temperature and voltages with a graphical user interface within Windows, rather than through the BIOS .
Nvidia Optimus is a computer GPU switching technology created by Nvidia which, depending on the resource load generated by client software applications, will seamlessly switch between two graphics adapters within a computer system in order to provide either maximum performance or minimum power draw from the system's graphics rendering hardware.
NVIDIA's PureVideo HD video rendering technology is an improved version of the original PureVideo introduced with GeForce 6. It now includes GPU-based hardware acceleration for decoding HD movie formats, post-processing of HD video for enhanced images, and optional High-bandwidth Digital Content Protection (HDCP) support at the card level.
