    Phoronix: OpenCL Support Atop Gallium3D Is Here, Sort Of

    OpenCL is present in NVIDIA's Linux driver as well as the just-released Mac OS X 10.6, but there is support for the Open Computing Language coming forward in the open-source world through the Gallium3D driver infrastructure.Back in February we heard a goal of having OpenCL in Gallium3D by this summer and then in May we heard that it was hopefully soon along with an OpenGL 3.1 state tracker. Well, it's just about September and the summer is nearing an end, but we now have OpenCL support in the works.Over on the FreeDesktop.org Git server is now a mesa/clover repository...

    Is there any card/driver that you can test Gallium3d and its features (ie opencl) NOW????

      i dont know about linux but afaik both the ati and nvidia beta windows drivers support it.

        He was asking about Gallium3D and not about OpenCL
        Nothing's really stable right now AFAIK, but the intel and radeon drivers do have little support in some branch I think.

              I suspect Intel might be best bet still. radeon and Nouveau are just still getting there.

                From a while ago...

                T 1249065383 18<idr> I guess that will depend on what VMware's priorities are. We (Intel) aren't using Gallium, so I'm almost completely out of the loop there.
                T 1249065429 18<idr> The GL_ARB_geometry_shader spec was updated with 3.2 interactions.
                T 1249065534 31<michaellarabel>30 Intel will not be switching to Gallium3D once it has matured?
                T 1249065578 18<idr> I don't know, The problem is, and always has been, that we'd have to completely re-write our driver.
                T 1249065682 31<michaellarabel>30 Do you have any plans to bring OGL 3.x to classic Mesa?
                T 1249065813 18<idr> Since we just wrapped up our Q2 release, we're still formulating our future plans.
                T 1249065948 31<michaellarabel>30 Okay.

                  Actually, I think that Nouveau on nv40 cards used to be the most complete of the Gallium drivers for real 3D hardware. It might still be, actually.

                    TG/VMWare was also working on a driver for Cell processors IIRC.

                      what for?

                      i somehow get lost in what are the priorities for open source

                      it can have application in PCI cell cards for computations (or whatever) but that kind of hardware is somehow targeted to a very small part of the market

                      (except if someone is paying them as i suspect)

                        Actually Toshiba is already developing openCL support for their SpursEngine chips and don't forget the buttload of PS3's out there. (At least the older ones that could still run linux).

                          one reason for a cell driver is that the onboard nvidia chip is locked down when running Linux on the PS3 so one of the SPUs can be sacrificed for some 3d accel

                            again not many people use their PS3 as regular PCs

                            its pointless (flash sucks and you cannot browse your favorite porn site)



                            after the post about the SpursEngine i thought they might want to do something with TVs and stuff but a TV its not the place for computations...

                            anyway

                            once AMD finishes the work with classic mesa they will be able to port the code in gallium quite quickly (i think bridgman made a comment about it in the past)

                              Where it is going to be useful is when it comes down to real time capture and encoding of HD video, and that is a growing market. Not to mention the potential use in items like gimp and such.
