Introduction
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
Mesa uses an even/odd version number scheme like the Linux kernel.
|
|
|
|
|
Odd numbered versions (such as 6.1) designate new developmental releases.
|
|
|
|
|
Even numbered versions (such as 6.0) designate stable releases.

Driver / context changes
|
|
|
|
|
------------------------
|
|
|
|
|
|
|
|
|
|
The _mesa_create_context() and _mesa_initialize_context() function
|
|
|
|
|
parameters have changed. They now take a pointer to a struct
|
|
|
|
|
dd_function_table. Drivers can initialize this table by calling
|
|
|
|
|
_mesa_init_driver_functions(). Drivers should then plug in the special
|
|
|
|
|
functions they implement. In particular, the ctx->Driver.NewTextureObject
|
|
|
|
|
pointer _must_ be set so that the default texture objects created in
|
|
|
|
|
_mesa_create/initialize_context() are correctly built.
|
|
|
|
|
|
|
|
|
|
The _mesa_init_driver_functions() function allows a lot of redundant code
|
|
|
|
|
to be removed from the device drivers (such as initializing
|
|
|
|
|
ctx->Driver.Accum to point to _swrast_Accum). Adding new functions to
|
|
|
|
|
the dd_function_table can be done with less hassle since the pointer can
|
|
|
|
|
be initialized in _mesa_init_driver_functions() rather than in _all_ the
|
|
|
|
|
drivers.

Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5
|
|
|
|
|
depending on the device driver's capabilities. For example, if the
|
|
|
|
|
driver enables all the ARB extensions which are part of OpenGL 1.5
|
|
|
|
|
then glGetString(GL_VERSION) will return "1.5". Otherwise, it'll
|
|
|
|
|
return "1.4" or the next lower version that implements all required
|
|
|
|
|
functionality.

|

|
A number of Mesa's software drivers haven't been actively maintained for
|
|
|
|
|
some time. We rely on volunteers to maintain many of the drivers.
|
|
|
|
|
Here's the current status of all included drivers:
