About Intel® Linux* Graphics

Linux* graphics is an ongoing field of interest at Intel’s Open Source
Technology Center (OTC). Community contributions range from driver
development and refinement to widespread project involvement, with a
particular focus on advancing standards for Open Source graphics.
Current OTC graphics work covers a broad range of efforts and projects,
such as: :

    Kernel driver is the core of the Intel Linux Graphics project, being 
responsible for all interactions with the hardware, driving different video 
outputs, mode setting, and converting bits into on-screen visible pixels.
    Mesa is the library responsible for 3D rendering, OpenGL compatibility, 
GLES and all the 3d-related components of Graphics on Linux and Unix systems
    XF86-Video-Intel, also known as DDX is the driver responsible for the 2D 
rendering within the X window system
    LibDRM is the middleware responsible for conversations between user 
applications and kernel driver itself
    Cairo Graphics is the 2D rendering and acceleration library
    VA API is the part of the stack responsible for hardware-accelerated video 
rendering, pre- and post-processing and output
    Wayland is the ongoing research project on next generation of window 
systems and composers
