Should be fixed now. 98ce1373e47d05d7150933c391fdeddbc897a3cd is the first bad commit commit 98ce1373e47d05d7150933c391fdeddbc897a3cd Author: Stéphane Marchesin <marcheu@chromium.org> Date: Wed Jun 22 16:51:02 2011 -0700 i915g: Add draw point sprites. It's not that much work; hopefully blend func separate also works and we get GL 2.0 for real. :040000 040000 ba49c082fa7ef28ea00f89675eb4e78abc471b35 6f6f68f2559303df0e7041dc1190cd1587557753 M src bisect run success mesa: 773556e0f537eba82d9d68d618e229140f413620 (master) piglit point-sprite passes on i915g. |
