    Phoronix: Mesa 9.0 Officially Released, Supports OpenGL 3.1

    After facing some delays, Mesa 9.0 was released on Monday afternoon as the latest bi-annual feature release of this important open-source OpenGL driver stack. This is also the first release that supports OpenGL 3.1, albeit the hardware support is currently limited to the Intel DRI driver...

    "
    The VDPAU state tracker is also considered "complete" now for Gallium3D support of NVIDIA's Video Decode and Presentation API for Unix, except this means of shader-based video acceleration is currently limited to MPEG1 and MPEG2 formats."

    Could somebody please clarify this? Does this mean that drivers such as r300g are now working with VDPAU acceleration? If so, I'd say that's pretty big news. I saw that VDPAU was still listed as "TODO" for r300g, so some clarification would be great.

      My guess is that means that the front-end code is done and works on a reference implementation (softpipe or llvmpipe). Probably a bit more work needs to be done to make sure all the back-ends support it.

        What is the state of radeonsi? When it is planned to be ready?

          I hpe that would mean that MPEG4 and its variations would follow soon just in time that users still would be happy to have it as next gen codecs probably are on the way. I read not long ago that H.265 standard promissing even greater compresion was already ratified...

          PS On the side note Libva 1.1.0 reappeareed couple days ago

            Do not expectate much from VDPAU

            If codecs are patented than they will not land in MESA.

            Maybe as 3rd party library? But not in mainland mesa.

            Mesa 10 will bring OpenGL 3.2/3.3 and OpenGL ES 3.0 right?

              Not sure about OpenGL ES 3.0, but I'd be quite surprised if it didn't. To pick up a slightly pedantic point, it won't be Mesa 10 unless it supports a new major version of OpenGL. The work for OpenGL 3.3 is done, it's just OpenGL 3.2 features that are missing (multisample textures, geometry shaders and GLSL 1.5).

                OpenGL 3.1 were released on March 24, 2009.
                So we are still more than 3 years behind in terms of technology.

                However, we may soon get OpenGL 3.2 and 3.3 support since some of it is partially implemented.

                OpenGL 4 is probably going to be a tough one though.

                  Intel is strongly interested in OpenGL ES 3.0. They will also probably certyfy it. As they did with OpenGL ES 2.0. So for now MESA is officially OpenGL ES 2.0 implementation

                  PS Folks at Intel think that OpenGL 3.2 and ES 3.0 are closly related, so maybe they will wait for OGL that will be slower to implement cause it will not take long if any.

                    It will be unless some crayzy student come along But 4.1 / 4.2 / 4.3 / (eventuall) 4.4 will be a bit easier as they just "refine" OGL.

                      How do you explain mpeg2 being there? It's also patented.

                      This isn't about patents, it's about one simple thing: GPUs aren't actually suitable for video decoding. A lot of effort required for not much gain. See this post for example, there's also a bit more discussion later in the thread.

                        I do think that Xvid or x264 efforts are patented. Besides I would rather disagree there is not much to gain with hardware decoding. There is pleanty of devices which cope with decoding of Full HD material only if done by the graphics driver example of which would be many low powered devices including AMD E-350 which I am happy owner of.

                        IMHO it would be great gain for Linux in general if one could use device like that to it full extend therefore I believe that mesa should extend its vdpau implementation or add a way to use external vaapi that is done so great by Intel guys

                          OpenGL 3.1 yes, but not for Radeons

                          The title says it all. If a multimillion company can't make a decent driver, then I guess I'll buy a NVIDIA card next time. Yes, their driver is closed source, but at least it works and is environment friendly.

                            so what would i need to start playing with openCL and clover? I guess i'd need a newer card than a HD3650. is clover complete enough to compile GEGL and have an openCL enabled GIMP?

                              End the F.U.D.

                              FGLRX supports OGL 3.1. FGLRX supports up into the OGL 4.x ranges. You're getting things mixed which shouldn't be mixed.

                              We're talking about the open source drivers here, in which AMD has in a lot of ways started over. Who knows when, but the OSS driver will eventually reach feature-parity with AMD's closed driver.
