Hi devs, The first attached patch fixes the calculation of mipmapped 3D texture sizes in the CS checker, the 3rd dimension (depth) should be minified too. This should probably go to 2.6.34. The second patch adds 2 new regs: - VAP_ALT_NUM_VERTICES, along with an update to the CS checker. - VAP_INDEX_OFFSET, I don't think this one needs to be tracked, because we have min/max vertex index clamping, but I might be wrong. Both probably need a DRM version bump so that I can detect them in userspace. Please review. -Marek
