These patches introduce a MESA API type of API_OPENGL_CORE,
which will not support legacy/non-CORE features. The intended
usage will be with contexts for Desktop GL>= 3.1.
The series will currently cause legacy/non-CORE functions
to generate a GL_INVALID_OPERATION error if an API_OPENGL_CORE
context is created.
Since MESA currently cannot create a context of API_OPENGL_CORE,
this series should not actually change the behaviour of MESA.
Future changesets will add the ability to create API_OPENGL_CORE
contexts.
This series also does not address deprecated enums usage for
CORE contexts.
v2:
* Decompose patches further
* Drop DRI changes
* Drop state_tracker changes
* Drop MESA_GL_API_OVERRIDE variable
v1:
* Add CORE API type
* Alter code paths to generate errors for legacy functions
* Add MESA_GL_API_OVERRIDE variable
Jordan Justen (7):
mesa: add API_OPENGL_CORE api
mesa: add api check macros
mesa: add support for using API_OPENGL_CORE
glsl: add support for using API_OPENGL_CORE
meta: add support for using API_OPENGL_CORE
intel: add support for using API_OPENGL_CORE
mesa: don't enable legacy GL functions when using API_OPENGL_CORE
I don't recall seeing the v1 series of these patches.
I reviewed them and gave Jordan some feedback before he sent them out to
the list.
I also don't recall any discussion about whether we should support core
profiles. But I'm glad to see this.
Initially the core profile infrastructure is for OpenGL 3.0
forward-compatible contexts. We'll eventually need it OpenGL 3.2. I'd
also like to piggyback some changes on this series to kill off the GLES
wrappers.
Some people will probably want to create core-profile GL apps and it's
difficult to know if you're really being core-profile-compliant if your
GL implementation only supports the full/legacy profile. It's easy to
accidently use a legacy feature and not realize it.
I have some comments on the patches themselves...
