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.
Nvidia and a partner, Avionic Design, were working on submitting Grate (free and open-source drivers for Tegra) upstream of the mainline Linux kernel in April 2012. [50] [51] The company's co-founder and CEO laid out the Tegra processor roadmap with Ubuntu Unity at the 2013 GPU Technology Conference. [52]
On September 3, 2008, Phoronix Test Suite 1.2 was released with support for the OpenSolaris operating system, [28] a module framework accompanied by tests focusing upon new areas, [29] and new test profiles. Phoronix Test Suite 1.8 includes a graphical user interface (GUI) using GTK+ written using the PHP-GTK bindings.
Gallium3D has been a part of Mesa since 2009 [156] and is currently used by the free and open-source graphics driver for Nvidia (nouveau project), [157] [158] for AMD's R300–R900, [159] [160] [161] Intel's 'Iris' driver for generation 8+ iGPUs [162] and for other free and open-source GPU device drivers.
GPUOpen HIP: A thin abstraction layer on top of CUDA and ROCm intended for AMD and Nvidia GPUs. Has a conversion tool for importing CUDA C++ source. Supports CUDA 4.0 plus C++11 and float16. ZLUDA is a drop-in replacement for CUDA on AMD GPUs and formerly Intel GPUs with near-native performance. [33]
The Direct Rendering Manager (DRM) is a subsystem of the Linux kernel responsible for interfacing with GPUs of modern video cards.DRM exposes an API that user-space programs can use to send commands and data to the GPU and perform operations such as configuring the mode setting of the display.
Video Acceleration API (VA-API) is an open source application programming interface that allows applications such as VLC media player or GStreamer to use hardware video acceleration capabilities, usually provided by the graphics processing unit (GPU).
GPU performance benchmarked on GPU supported features and may be a kernel to kernel performance comparison. For details on configuration used, view application website. Speedups as per Nvidia in-house testing or ISV's documentation. ‡ Q=Quadro GPU, T=Tesla GPU. Nvidia recommended GPUs for this application.
