Explicit GL (XGL) Ecosystem Components

Version 0.2, 31 Oct 2014

This project provides open source components for the XGL Ecosystem.

The components here are being shared with the Khronos community to provide early insights into the specification of XGL and to assists those doing prototyping at this point.

The following components are available:

• Proposed Reference ICD Loader (including Layer Management)
• Proposed Reference Validation Layers
  • Object Tracker
  • Draw State
• GLAVE Debugger (API Dump only)
• Sample Driver
  • Common Infrastructure
  • Implementation for Intel GPUs

This version of the components are written based on the following preliminary specs and proposals:

• XGL Programers Reference, 1 Jul 2014
• BIL, version 1.0, revision 18
• IMG's Fixed Function Proposal, 28 Oct 2014
• Valve's Loader Proposal, 7 Oct 2014

This work is intended to be released as open source under a BSD-style license once the XGL specification is public. Until that time, this work is covered by the Khronos NDA governing the details of the XGL API.

While this project is being developed by LunarG, Inc; there are many other companies and individuals making this possible: Valve Software, funding project development; Intel Corporation, providing full hardware specifications and valuable technical feedback; AMD, providing XGL spec editor contributions; ARM, contributing a Chairman for this working group within Khronos; Nvidia, providing an initial co-editor for the spec; Qualcomm for picking up the co-editor's chair; and Khronos, for providing hosting within GitHub.

If you have questions or comments about this driver, please post those to gl_common@khronos.org; or if you prefer, directly to LunarG via XGL@LunarG.com
