An operating system abstraction layer (OSAL) provides an application programming interface (API) to an abstract operating system making it easier and quicker to develop code for multiple software or hardware platforms. It can make an application less dependent on any one specific operating system.
DXVK was first developed by Philip Rebohle to support Direct3D 11 games only [13] as a result of poor compatibility and low performance of Wine's Direct3D 11 to OpenGL translation layer. In 2018, the developer was sponsored by Valve to work on the project full-time in order to advance compatibility of the Linux version of Steam with Windows ...
Proton is a compatibility layer that allows Windows software (primarily video games) to run on Linux-based operating systems. [1] Proton is developed by Valve in cooperation with developers from CodeWeavers. [2] It is a collection of software and libraries combined with a patched version of Wine to
DirectFB (Direct Frame Buffer), now continued as DirectFB2, is a software library with a small memory footprint that provides graphics acceleration, input device handling and abstraction layer, and integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer without requiring any kernel modifications.
Even on similar systems, the details of implementing a compatibility layer can be quite intricate and troublesome; a good example is the IRIX binary compatibility layer in the MIPS architecture version of NetBSD. [25] A compatibility layer requires the host system's CPU to be (upwardly) compatible to that of the foreign
SDL is a wrapper around the operating-system-specific functions that the game needs to access. The only purpose of SDL is to provide a common framework for accessing these functions for multiple operating systems (cross-platform). [30] SDL provides support for 2D pixel operations, sound, file access, event handling, timing and threading.
L4 is a family of second-generation microkernels, used to implement a variety of types of operating systems (OS), though mostly for Unix-like, Portable Operating System Interface compliant types. L4, like its predecessor microkernel L3 , was created by German computer scientist Jochen Liedtke as a response to the poor performance of earlier ...
The Embeddable Linux Kernel Subset (ELKS), formerly known as Linux-8086, is a Linux-like operating system kernel.It is a subset of the Linux kernel, intended for 16-bit computers with limited processor and memory resources such as machines powered by Intel 8086 and compatible microprocessors not supported by 32-bit Linux.
