Hello! This patch series bumps the kernel requirement to 3.6 for Gen6+, meaning that we actually get to rely on hardware context support. That's a little painful, but even Debian ships 3.8 now, and this isn't going to make it into an actual release for several more months.
It then splits our query code into Gen4-5 and Gen6+ versions. The new Gen6+ version is a lot simpler since hardware contexts guarantee that our statistics registers don't get polluted with data from other programs running on the system. It should be more efficient, which may help games like Minecraft (though I haven't measured). Finally, it implements the GL_PRIMITIVES_GENERATED and GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN queries via hardware counters rather than manually counting on the CPU. This paves the way for geometry shader support (which can output multiple primitives, breaking our CPU-side tracking), and should allow us to enable hardware primitive restart in a few more cases once a few more things are tidied. The next step is to eliminate the use of SOL reset and save/restore the transform feedback offsets directly. Then we can turn on hardware primitive restart more aggressively and implement a few more transform feedback extensions. Thanks in advance for the review. --Ken _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
