    Phoronix: Beignet Is Now Friendly With LLVM/Clang 3.5

    I am confused, didn't Intel say they were disengaging from LLVM as a platform for OpenCL?

      Nope, they don't want it as a GLSL compiler.

        According to Ian Romanick answer on Steam Dev Days (at 39:03) team that working on OpenCL is completely unrelated to team that working on Mesa.

          And the next round of tests of OpenCL implementations with inclusion of free drivers will be made ...
          When?

              Hi Michael,
              The following statement is not fully accurate:
              "Intel's Beignet open-source OpenCL implementation for their Linux graphics driver now switches to LLVM/Clang 3.5 as its preferred version. "

              Till now, the preferred LLVM/Clang is still 3.3 not 3.5. As there is a important bug outstanding there in LLVM/Clang 3.5. After that bug get fixed,
              I will switch preferred version to 3.5.

              BTW, I just made a new release for beignet 0.8.0. You can get the release notes at:

                Pontostroy, can you see if cgminer runs on the Ivy?

                  I only have bfgminer

                  bfgminer --sharelog shares.txt --debuglog -o mining.eligius.st:3334 -O addrass --gpu-threads=1 -v1 -k phatk

                    Gentoo Overlay

                    I'm still maintaining a gentoo overlay with modified mesa ebuilds integrating beignet:

                      I'm not interested in plain bfgminer, does it work with --scrypt? radeonsi does not still work with scrypt (no litecoin mining).

                        Yeah, sorry, forgot to say with scrypt. Though good to know beignet already does sha.

                        (2.8 MH/s on the ivy gpu? That's worse than Via Padlock)

                          The beignet devs haven't really put any time into performance work as of yet, they've been working on ocl-1.1/1.2 coverage. However, quite likely the problem here is due to gpu lock-ups (which I get currently when running "pyrit benchmark"); it should certainly be much faster!
