Hybris (software)
Hybris or libhybris is a compatibility layer for computers running Linux distributions based on the GNU C library or Musl, intended for using software written for Bionic-based Linux systems, which mainly includes Android libraries and device drivers. History Hybris was initially written by Carsten Munk, a Mer developer, who released it on GitHub on 5 August 2012 and publicly announced the project later that month. Munk has since been hired by Jolla as their Chief Research Engineer. Hybris has also been picked up by the Open webOS community for WebOS Ports, by Canonical for Ubuntu Touch and by the AsteroidOS project. In April 2013, Munk announced that Hybris has been extended to allow Wayland compositors to use graphic device drivers written for Android. Weston has had support for libhybris since version 1.3, which was released on 11 October 2013. Features Hybris loads "Android libraries, and overrides some symbols from bionic with glibc" calls, making it possible to ...

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free And Open-source Graphics Device Driver
A free and open-source graphics device driver is a software stack which controls computer-graphics hardware and supports graphics-rendering application programming interfaces (APIs) and is released under a free and open-source software license. Graphics device drivers are written for specific hardware to work within a specific operating system kernel and to support a range of APIs used by applications to access the graphics hardware. They may also control output to the display if the display driver is part of the graphics hardware. Most free and open-source graphics device drivers are developed by the Mesa project. The driver is made up of a compiler, a rendering API, and software which manages access to the graphics hardware. Drivers without freely (and legally) -available source code are commonly known as ''binary drivers''. Binary drivers used in the context of operating systems that are prone to ongoing development and change (such as Linux) create problems for end users an ...

C Standard Library
The C standard library or libc is the standard library for the C programming language, as specified in the ISO C standard.ISO/IEC (2018). '' ISO/IEC 9899:2018(E): Programming Languages - C §7'' Starting from the original ANSI C standard, it was developed at the same time as the C library POSIX specification, which is a superset of it. Since ANSI C was adopted by the International Organization for Standardization, the C standard library is also called the ISO C library. The C standard library provides macros, type definitions and functions for tasks such as string handling, mathematical computations, input/output processing, memory management, and several other operating system services. Application programming interface Header files The application programming interface (API) of the C standard library is declared in a number of header files. Each header file contains one or more function declarations, data type definitions, and macros. After a long period of stabi ...

EGL (OpenGL)
EGL is an interface between Khronos rendering APIs (such as OpenGL, OpenGL ES or OpenVG) and the underlying native platform windowing system. EGL handles graphics context management, surface/buffer binding, rendering synchronization, and enables "high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs." EGL is managed by the non-profit technology consortium Khronos Group. The acronym ''EGL'' is an initialism, which starting from EGL version 1.2 refers to ''Khronos Native Platform Graphics Interface''. Prior to version 1.2, the name of the EGL specification was ''OpenGL ES Native Platform Graphics Interface''. X.Org development documentation glossary defines EGL as "Embedded-System Graphics Library". Adoption * The BlackBerry 10 and BlackBerry Tablet OS mobile device operating system uses EGL for 3D graphics rendering. Both support EGL version 1.4. * The Android mobile device operating system uses EGL for 3D graphics rendering. * The Wayland ...

Binary Blob
In the context of free and open-source software, proprietary software only available as a binary executable is referred to as a blob or binary blob. The term usually refers to a device driver module loaded into the kernel of an open-source operating system, and is sometimes also applied to code running outside the kernel, such as system firmware images, microcode updates, or userland programs. The term ''blob'' was first used in database management systems to describe a collection of binary data stored as a single entity. When computer hardware vendors provide complete technical documentation for their products, operating system developers are able to write hardware device drivers to be included in the operating system kernels. However, some vendors, such as Nvidia, do not provide complete documentation for some of their products and instead provide binary-only drivers. This practice is most common for accelerated graphics drivers, wireless networking devices, and hardwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glibc
The GNU C Library, commonly known as glibc, is the GNU Project's implementation of the C standard library. Despite its name, it now also directly supports C++ (and, indirectly, other programming languages). It was started in the 1980s by the Free Software Foundation (FSF) for the GNU operating system. Released under the GNU Lesser General Public License, glibc is free software. The GNU C Library project provides the core libraries for the GNU system, as well as many systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, exit and more. History The glibc project was initially written mostly by Roland McGrath, working for the Free Software Foundation (FSF) in the 1980s as a teenager. In February 1988, FSF described glibc as having nearly completed the func ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weston (software)
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a ''Wayland compositor'', because it additionally performs the task of a compositing window manager. Wayland is developed by a group of volunteers initially led by Kristian Høgsberg as a free and open-source community-driven project with the aim of replacing the X Window System with a modern, secure simpler windowing system in Linux and other Unix-like operating systems. The project's source code is published under the terms of the MIT License, a permissive free software licence. As part of its efforts, the Wayland project also develops a reference implementation of a Wayland compositor called ''Weston''. Overview The Wayland Display Server project was started by Red Hat developer Kristian Høgsberg in 2008. Beginning around 2010, Linux desktop graphics h ...

Ubuntu Touch
Ubuntu Touch is a mobile version of the Ubuntu operating system, being developed by the UBports community. Its user interface is written in Qt, and is designed primarily for touchscreen mobile devices such as smartphones and tablet computers, but the original goal of convergence was intended to bring Ubuntu Touch to laptops, desktops, IOT devices and TVs for a complete unified user experience. The project was started by Canonical Ltd. but Mark Shuttleworth announced that Canonical would terminate support due to lack of market interest on 5 April 2017. It was then adopted by UBports as a community project. The UBports project was seeded by Marius Gripsgard in 2015 and the source code was transferred to the UBports Foundation where it now resides. UBports' mission is to support the collaborative development of Ubuntu Touch and to promote its widespread use. History The Ubuntu Touch project was started in 2011.
