There are two reasons: 1. Because atoms get reused all the time across generations, it is just easier to use the _mesa_geomety_* functions in any batch buffer builder that is concerned about the geometry of the render target. It keeps the code consistent and much easier than checking what functions and atoms are directly or indirectly used by different Gens. However, blorp, blitting and a few others are left untouched since they want to talk about the buffer, not really 3D pipeline rasterization things. 2. At first I was going to support pre Gen7 hardware with the series. However, I do not have hardware on which to test it. In truth I want this to also run on pre-Gen7, but without testing on device, I cannot vouch for the patches. I believe it should just work for pre Gen7 (by just tweaking the last patch to enable it on pre Gen7), but I would rather be careful than in this case. I also confess, it is a silly extension for pre Gen7 anyways... -Kevin _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
