But until this second=20 I believed AMD opened their specs for the community.

Apple, for instance,=20 develop their own stuff on the basis of OpenCL and LLVM, but they do not = publish back to the community, that's right.

Their hw sucks and= > their software is a joke.. (if you bought Evergreen I'm sorry..) Well, look at my first statement. Until now I believe and believed AMD=20 offered more than others of their 3D specs to the open source community, = to provide support to real open source GPU drivers. Obviously this isn't = true anymore. But why hasn't this been made public? AMD earns a lot of=20 money even from those people like me which remain in the strong=20 believing that they made their contribution to the open source OS communi= ty. But at the moment, looking at my hardware running FreeBSD, I realize=20 that I have more and better running hardware based on nVidia and their=20 BLOB than hardware based on AMD. But this is individual. > > There's no such thing as a complete open source GPGPU solution as of > today (to the best of my knowledge) Well, not completely open source, but there is an nVidia CUDA solution=20 even for 64 Bit Linux and none for FreeBSD!
