    Phoronix: Intel "Crocus" Driver For Old iGPUs Bumps OpenGL Compatibility Profile Support

    The Intel Crocus Mesa driver providing open-source Gallium3D support for older i965 through Haswell era graphics hardware is now offers much better OpenGL compatibility profile support...

    My Dell D630 just keeps kickin’! Core 2 Extreme CPU upgrade, 8GB RAM, Blu-Ray Burner, 1TB SSD, and now: those 965/X3100/Crestline graphics just keep things working smoothly.

    …. Now just need beignet to support OpenCL on elderly GPUs 😂

      Or for Mesa OpenCL to mature.

        So does Crocus support Ivy? Nice!

          Typo: It should be "now offers" or "is now offering".

            Maybe I'm wrong but as far as I know there is no Intel implementation in Mesa OpenCL, also Mesa OpenCL is hardware-specific (like with OpenGL where there is iris, crocus, r600, radeonsi, nouveau…) so getting one platform working would not mean other platforms would be working.

              It appears that restriction was a Crockus-shit.

                Well, I think it's a case of "both-and". Bth Mesa OpenCL needs to mature AND the Crocus driver needs to implement support for the particular features. Still, it should be a lot less work than implementing OpenCL for Crocus from scratch.

                BTW, what's the story behind the name Crocus?

                  Correct me if I am wrong, but I believe the Mesa driver (or wherever it comes from) for the newer Intel graphics is called Iris, which is a flower. Crocus is also a flower! In fact, per below, it is part of the Iris family of flowers! There you have it

                    To my understanding this change is important for wine to run. I suffer the issue below and it seems this change would fix the issue on Crocus :-)
