UMA Acceleration Architecture
In computing, UMA Acceleration Architecture (UXA) is the reimplementation of the EXA graphics acceleration architecture of the X.Org Server developed by Intel. Its major difference with EXA is the use of GEM, replacing Translation Table Maps. In February 2009 it became clear that UXA would not be merged back into EXA. Intel is transitioning from UXA to SNA. Implementations In May 2009 it was announced that Ubuntu would migrate their graphics acceleration for the Ubuntu 9.10 release to UXA.

Linux Graphics Drivers 2D
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for servers may ...

The Linux Graphics Stack And Glamor
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and development of both hardware and software. Computing has scientific, engineering, mathematical, technological and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology and software engineering. The term "computing" is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathematical conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Direct Rendering Manager
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. DRM was first developed as the kernel-space component of the X Server Direct Rendering Infrastructure, but since then it has been used by other graphic stack alternatives such as Wayland. User-space programs can use the DRM API to command the GPU to do hardware-accelerated 3D rendering and video decoding, as well as GPGPU computing. Overview The Linux kernel already had an API called fbdev, used to manage the framebuffer of a graphics adapter, but it couldn't be used to handle the needs of modern 3D-accelerated GPU-based video hardware. These devices usually require setting and managing a command queue in their own memory to dispatch commands to the GPU and also require management ...

Ubuntu
Ubuntu ( ) is a Linux distribution based on Debian and composed mostly of free and open-source software. Ubuntu is officially released in three editions: ''Desktop'', ''Server'', and ''Core'' for Internet of things devices and robots. All the editions can run on the computer alone, or in a virtual machine. Ubuntu is a popular operating system for cloud computing, with support for OpenStack. Ubuntu's default desktop changed back from the in-house Unity to GNOME after nearly 6.5 years in 2017 upon the release of version 17.10. Ubuntu is released every six months, with long-term support (LTS) releases every two years. , the most-recent release is 22.10 ("Kinetic Kudu"), and the current long-term support release is 22.04 ("Jammy Jellyfish"). Ubuntu is developed by British company Canonical, and a community of other developers, under a meritocratic governance model. Canonical provides security updates and support for each Ubuntu release, starting from the release date and until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ubuntu Version History
Ubuntu releases are made semiannually by Canonical Ltd, the developers of the Ubuntu operating system, using the year and month of the release as a version number. The first Ubuntu release, for example, was Ubuntu 4.10 and was released on 20 October 2004. Consequently, version numbers for future versions are provisional; if the release is delayed until a different month (or even year) to that planned, the version number will change accordingly. Canonical schedules Ubuntu releases to occur approximately one month after GNOME releases, resulting in each Ubuntu release including a newer version of GNOME. Every fourth release, occurring in the second quarter of even-numbered years, has been designated as a long-term support (LTS) release. The desktop version of LTS releases for 10.04 and earlier were supported for three years, with server version support for five years. LTS releases 12.04 and newer are freely supported for five years. Through the ESM paid option, support can be exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Direct Rendering Infrastructure
The Direct Rendering Infrastructure (DRI) is the framework comprising the modern Linux graphics stack which allows unprivileged user-space programs to issue commands to graphics hardware without conflicting with other programs. The main use of DRI is to provide hardware acceleration for the Mesa implementation of OpenGL. DRI has also been adapted to provide OpenGL acceleration on a framebuffer console without a display server running. DRI implementation is scattered through the X Server and its associated client libraries, Mesa 3D and the Direct Rendering Manager kernel subsystem. All of its source code is free software. Overview In the classic X Window System architecture the X Server is the only process with exclusive access to the graphics hardware, and therefore the one which does the actual rendering on the framebuffer. All that X clients do is communicate with the X Server to dispatch rendering commands. Those commands are hardware independent, meaning that the ...

Mesa 3D
Mesa, also called Mesa3D and The Mesa 3D Graphics Library, is an open source implementation of OpenGL, Vulkan, and other graphics API specifications. Mesa translates these specifications to vendor-specific graphics hardware drivers. Its most important users are two graphics drivers mostly developed and funded by Intel and AMD for their respective hardware (AMD promotes their Mesa drivers Radeon and RadeonSI over the deprecated AMD Catalyst, and Intel has only supported the Mesa driver). Proprietary graphics drivers (e.g., Nvidia GeForce driver and Catalyst) replace all of Mesa, providing their own implementation of a graphics API. An open-source effort to write a Mesa Nvidia driver called Nouveau is mostly developed by the community. Besides 3D applications such as games, modern display servers ( X.org's Glamor or Wayland's Weston) use OpenGL/ EGL; therefore all graphics typically go through Mesa. Mesa is hosted by freedesktop.org and was initiated in August 1993 by Brian Paul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
