    Default Intel Mesa Driver Now Has GL 3.2 Multisample Textures

    Phoronix: Intel Mesa Driver Now Has GL 3.2 Multisample Textures

    The Intel Mesa DRI driver now supports GL_ARB_texture_multisample. The OpenGL multi-sample textures support is mandated by OpenGL 3.2...

    Seen talk about appropriating those intel patches for r600g on mesa mailing list (G-Truc do nice OpenGL comparisions, but Linux+Intell got omited due to lack of this very extension)

    PS Anyone know if Mesa can be forced to support arbitrary GLSL language (so I can see what exactly is not working?)

    We've had multisample textures in r600g since Mesa 9.0. Only the core Mesa bits were missing, which is being tackled now.

    Could you explain a little about how that works? Were applications able to use the multisample textures in r600g? What mesa code needed to be added/what did it do?

    Multisample textures were required to implement glBlitFramebuffer with MSAA renderbuffers for R600. Gallium and TGSI support was in place too. No, applications couldn't use it in any other way. Only the GL and GLSL functions from GL_ARB_texture_multisample were missing.
