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. + + + + + +Device Drivers +-------------- + +Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on +the device driver. For example, if the driver enables all the ARB +extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION) +will return "1.3". Otherwise, it'll return "1.2". + +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: + + +Driver Status +---------------------- --------------------- +XMesa (Xlib) implements OpenGL 1.5 +OSMesa (off-screen) implements OpenGL 1.5 +FX (3dfx Voodoo1/2) implements OpenGL 1.3 +SVGA implements OpenGL 1.3 +Wind River UGL implements OpenGL 1.3 +Windows/Win32 implements OpenGL 1.5 +DJGPP implements OpenGL 1.5 +GGI implements OpenGL 1.3 +BeOS implements OpenGL 1.5 +Allegro needs updating +D3D needs updating + + + + +Other Changes +------------- + +See the VERSIONS file for more details about bug fixes, etc. in Mesa 6.0. + + +---------------------------------------------------------------------- +$Id: RELNOTES-6.1,v 3.1 2004/01/20 02:54:51 brianp Exp $ -- cgit v1.2.3
