License and Copyright¶
Disclaimer¶
Mesa implements various APIs, including OpenGL, OpenGL ES, Vulkan and OpenCL. Even though Mesa implements these APIs, the implementation isn’t formally conformant on all combinations of drivers and hardware. Khronos maintains lists of conformant implementations for each of their APIs, as well as trademark details.
Please do not refer to the library as MesaGL (for legal reasons). It’s just Mesa or The Mesa 3-D graphics library.
License / Copyright Information¶
The Mesa distribution consists of several components. Different copyrights and licenses apply to different components. For example, the GLX client code uses the SGI Free Software License B, and some of the Mesa device drivers are copyrighted by their authors. See below for a list of Mesa’s main components and the license for each.
The core Mesa library is licensed according to the terms of the MIT license. This allows integration with the XFree86, X.Org and DRI projects.
