It > needs to be reported to them, and they need to fix it. Period. I reported the bugs to SPEC a few weeks ago. Their website's "contact us" person forwarded my email which detailed the problems (and an offer to write a patch to correct things) to a technical person (supposedly) but I haven't received a reply yet. I could ping them again. If you'd take a look at Viewperf 11's checkExtensions() function you'd probably crap your pants. It looks like someone made a half-hearted attempt at querying some OpenGL features then just gave up. It's pretty bad. A few viewperf tests use Cg-generated shaders that apparently were simply captured on an NVIDIA host and baked into the test. Of course, you can't expect an arbitrary Cg-generated shader to work on a different host. For example, the catia test uses GL_NV_fragment_program2 in one place (an IF/ELSE/ENDIF) and GL_NV_vertex_program3 in a few others (but the shaders only have some "label:" lines with no actual branches to them). Then, there's some use of GL_NV_primitive_restart which is predicated on whether glXGetProcAddress() returns non-null. Ugh. As Jose mentioned, we have a fairly small patch that lets the ARB vp/fp compiler accept these shaders. In general, I don't like adding work-arounds like this into Mesa any more than anyone else. But it's always a trade-off. The upside of doing a "hack" is that people can run their apps/games/benchmarks/etc and get on with things. The alternative is to get error reports like the above and general hear-say of "things don't run with Mesa". I'd bet all the commercial OpenGL vendors have some number of hacks added just so that important applications run to satisfy their users. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
