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.
AMDgpu is an open source device driver for the Linux operating system developed by AMD to support its Radeon lineup of graphics cards (GPUs). It was announced in 2014 as the successor to the previous radeon device driver as part of AMD's new "unified" driver strategy, [3] and was released on April 20, 2015.
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.
When it was first introduced, the name was an acronym for Compute Unified Device Architecture, [3] but Nvidia later dropped the common use of the acronym and now rarely expands it. [4] CUDA is a software layer that gives direct access to the GPU's virtual instruction set and parallel computational elements for the execution of compute kernels. [5]
[17] [18] In May 2007, ATI included Steam in the ATI Catalyst GPU driver as well as offering a free Steam copy of Half-Life 2: Lost Coast and Half-Life 2: Deathmatch to ATI Radeon owners. [19] In January 2008, Nvidia promoted Steam in the GeForce GPU driver, as well as offering a free Steam copy of Portal: The First Slice to Nvidia hardware ...
The Hybrid CrossFireX is a technology allowing the IGP, or Integrated Graphics Processor, and the discrete GPU, or Graphics Processing Unit, to form a CrossFire setup to enhance the system capability to render 3D scenes, while the Hybrid CrossFire X technology is present on the 790GX and 890G chipsets, with two supplied physical PCI-E x16 slots at x8 bandwidth, [12] can form a Hybrid CrossFire ...
they are meant to work on top of additionally existent kernel mode graphics device drivers, that are e.g. available as part of the Linux kernel found in the source code under /drivers/gpu/drm/ Each UMD communicates with its kernel mode counterpart with the help of a specific library, name libdrm_specific and a generic one, named libdrm. This ...
General-purpose computing on graphics processing units (GPGPU, or less often GPGP) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU).
