With mesa, a driver that only supports GL 3.1 will still be recognized as a core context. It has to jump through hoops on, say, NVIDIA though, since that returns a context that has ARB_compatibility exposed and so it goes back and requests a GL3.2 core context. At least one piece of hardware I semi-care about (Adreno A3XX) will likely have GL 3.1, but never get GL 3.2 due to lack of GS. -ilia _______________________________________________ Piglit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/piglit
