So some testing I made today with piglit and games. mesa-7.8.1-1455-g5acee66 : 95/174 mesa-7.8.1-1466-g3c0120d : 115/174 mesa-7.8.1-1468-g81bdeee : 114/174 The breakage between 3c0120d and 81bdeee is texturing/lodbias and is caused by the above commit : nvfx: rewrite render temporaries code, also affecting 2D and resource code This same commit also broke the following games : etracer, glest, neverball, foobillard (when using hwtnl, which is the default). The testing work Luca and I made trying to resolve this issue can be seen there : http://repo.or.cz/w/mesa/mesa-lb.git/shortlog/refs/heads/nvfx-next-6b-nv30 If anyone wants to rebase the whole nvfx-next-6b branch without temporaries on top of master, I will happily test that as well. Some interesting piglit changes between old master mesa-7.8.1-1455-g5acee66 and new master mesa-7.8.1-2941-g9ef6d34 : 1) polygonOffset fails polygonOffset: FAIL rgba8, db, z24, s8, win+pmap, id 33 Actual MRD is too large (may waste depth-buffer range) Ideal MRD at near plane is 5.82077e-11 (nominally 0 bits) Actual MRD at near plane is 5.96046e-08 (nominally 1 bit) Ideal MRD at infinity is 5.86733e-08 (nominally 1 bit) Actual MRD at infinity is 1.19209e-07 (nominally 2 bits) 2) fp-long-alu fails Testing: alu_depth = 3077 Probe at (16,16) Expected: 0.312500 0.000000 0.750000 0.000000 Observed: 0.000000 0.000000 0.000000 0.000000 3-4) texEnv and levelclamp pass _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
