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.
VA-API video decode/encode interface is platform and window system independent but is primarily targeted at Direct Rendering Infrastructure (DRI) in X Window System on Unix-like operating systems (including Linux, FreeBSD, Solaris), and Android, however it can potentially also be used with direct framebuffer and graphics sub-systems for video ...
Free and open-source drivers are primarily developed on and for Linux by Linux kernel developers, third-party programming enthusiasts and employees of companies such as Advanced Micro Devices. Each driver has five parts: A Linux kernel component DRM; A Linux kernel component KMS driver (the display controller driver)
TechPowerUp GPU-Z (or just GPU-Z) is a lightweight utility designed to provide information about video cards and GPUs. [2] The program displays the specifications of Graphics Processing Unit (often shortened to GPU) and its memory; also displays temperature, core frequency, memory frequency, GPU load and fan speeds.
The Skia Graphics Engine or Skia is an open-source 2D graphics library written in C++.Skia abstracts away platform-specific graphics APIs (which differ from one to another). [1]
Geekbench began as a benchmark for Mac OS X and Windows, [3] and is now a cross-platform benchmark that supports macOS, Windows, Linux, Android and iOS. [4] In version 4, Geekbench started measuring GPU performance in areas such as image processing and computer vision. [5] In version 5, Geekbench dropped support for IA-32. [6]
In the Linux systems, a patch named vga_switcheroo [13] has been added to the Linux kernel since version 2.6.34 in order to deal with multiple GPUs. Here, the switch requires a restart of the X Window System to be taken into account. Ubuntu Control Center allows the user to access vga_switcheroo functionality through a GUI.
