   1 # Status of OpenGL extensions in Mesa
   2
   3 Here's how to read this file:
   4
   5 all DONE: <driver>, ...
   6     All the extensions are done for the given list of drivers.
   7
   8 DONE
   9     The extension is done for Mesa and no implementation is necessary on the
  10     driver-side.
  11
  12 DONE ()
  13     The extension is done for Mesa and all the drivers in the "all DONE" list.
  14
  15 DONE (<driver>, ...)
  16     The extension is done for Mesa, all the drivers in the "all DONE" list, and
  17     all the drivers in the brackets.
  18
  19 in progress
  20     The extension is started but not finished yet.
  21
  22 not started
  23     The extension isn't started yet.

  25 # OpenGL Core and Compatibility context support
  26
  27 OpenGL 3.1 and later versions are only supported with the Core profile.
  28 There are no plans to support GL_ARB_compatibility. The last supported OpenGL
  29 version with all deprecated features is 3.0. Some of the later GL features
  30 are exposed in the 3.0 context as extensions.
