After the sorting of OpenCL format regitration, DES is the first one. I think I'll put those two last for now, or disable them altogether until Sayanyan fixes them. >> >> magnum > > The "first" fix attached. mscash 2 works.

The latter now uses a split kernel, but only asked for max workgroup size for one of the kernels. The good thing about my crappy CPU driver is it triggers such bugs. Unfortunately it also triggers it in DES and I can't find how/where to fix it: Benchmarking: Traditional DES [OpenCL]... OpenCL error (CL_INVALID_WORK_GROUP_SIZE) in file (opencl_DES_bs_b.c) at line (410) - (Enque Kernel Failed) The BF format works on CPU here though, so it apparently obeys that limit. magnum
