Pushed the series to pixman git (with the second revision of the first patch with more comments). As a bonus, here are also the cairo-perf-trace results with the trimmed traces on Cortex-A9 1.7GHz (unfortunately not Tegra2, where this test would have been more relevant). I understand that Cortex-A9 was not the primary target for this patchset, but it's still good to know that we also get improvements there. === old armv6 === [ # ] backend test min(s) median(s) stddev. count [ # ] image: pixman 0.29.1 [ 0] image t-firefox-planet-gnome 2.860 2.865 0.24% 7/8 [ 1] image t-chromium-tabs 0.881 0.882 0.21% 7/8 [ 2] image t-gvim 4.949 4.959 0.26% 8/8 [ 3] image t-gnome-system-monitor 6.028 6.042 0.52% 7/8 [ 4] image t-firefox-canvas-alpha 3.962 3.983 0.31% 8/8 [ 5] image t-firefox-scrolling 6.981 6.987 0.06% 8/8 [ 6] image t-firefox-chalkboard 8.459 8.462 0.02% 8/8 [ 7] image t-swfdec-youtube 2.306 2.310 0.11% 8/8 [ 8] image t-firefox-particles 5.505 5.510 0.10% 8/8 [ 9] image t-firefox-fishbowl 5.684 5.697 0.11% 8/8 [ 10] image t-firefox-fishtank 4.816 4.819 0.02% 8/8 [ 11] image t-xfce4-terminal-a1 5.559 5.728 1.88% 8/8 [ 12] image t-poppler-reseau 3.178 3.244 0.75% 7/8 [ 13] image t-grads-heat-map 0.559 0.560 0.09% 8/8 [ 14] image t-firefox-talos-gfx 5.021 5.030 0.10% 7/8 [ 15] image t-firefox-asteroids 4.272 4.277 0.05% 7/8 [ 16] image t-midori-zoomed 2.087 2.088 0.06% 7/8 [ 17] image t-swfdec-giant-steps 3.788 3.791 0.04% 7/8 [ 18] image t-firefox-talos-svg 4.067 4.074 0.06% 8/8 [ 19] image t-poppler 2.735 2.743 0.25% 8/8 [ 20] image t-firefox-canvas 4.025 4.026 0.02% 7/8 [ 21] image t-evolution 4.428 4.619 2.19% 7/8 [ 22] image t-firefox-paintball 5.292 5.298 0.06% 8/8 [ 23] image t-gnome-terminal-vim 2.790 2.817 0.58% 7/8 === new armv6 === [ # ] backend test min(s) median(s) stddev. count [ # ] image: pixman 0.29.1 [ 0] image t-firefox-planet-gnome 2.798 2.806 0.23% 7/8 [ 1] image t-chromium-tabs 0.784 0.786 0.23% 7/8 [ 2] image t-gvim 4.944 4.972 0.42% 7/8 [ 3] image t-gnome-system-monitor 5.639 5.661 0.28% 7/8 [ 4] image t-firefox-canvas-alpha 3.768 3.773 0.12% 7/8 [ 5] image t-firefox-scrolling 6.890 6.897 0.11% 7/8 [ 6] image t-firefox-chalkboard 8.392 8.404 0.10% 8/8 [ 7] image t-swfdec-youtube 2.264 2.267 0.08% 7/8 [ 8] image t-firefox-particles 5.339 5.345 0.08% 7/8 [ 9] image t-firefox-fishbowl 5.178 5.189 0.13% 7/8 [ 10] image t-firefox-fishtank 4.414 4.415 0.02% 7/8 [ 11] image t-xfce4-terminal-a1 5.321 5.533 2.25% 8/8 [ 12] image t-poppler-reseau 3.208 3.248 0.64% 7/8 [ 13] image t-grads-heat-map 0.555 0.555 0.03% 6/8 [ 14] image t-firefox-talos-gfx 4.800 4.812 0.23% 7/8 [ 15] image t-firefox-asteroids 3.804 3.808 0.38% 7/8 [ 16] image t-midori-zoomed 1.952 1.953 0.11% 7/8 [ 17] image t-swfdec-giant-steps 3.622 3.629 0.08% 7/8 [ 18] image t-firefox-talos-svg 4.011 4.014 0.07% 7/8 [ 19] image t-poppler 2.712 2.717 0.20% 7/8 [ 20] image t-firefox-canvas 3.847 3.849 0.14% 7/8 [ 21] image t-evolution 4.034 4.064 0.32% 7/8 [ 22] image t-firefox-paintball 4.529 4.534 0.31% 7/8 [ 23] image t-gnome-terminal-vim 2.767 2.801 0.63% 7/8 Speedups ======== image t-firefox-paintball 5291.78 -> 4528.96 : 1.17x speedup image t-chromium-tabs 881.20 -> 783.62 : 1.12x speedup image t-firefox-asteroids 4272.31 -> 3804.48 : 1.12x speedup image t-evolution 4428.02 -> 4033.76 : 1.10x speedup image t-firefox-fishbowl 5683.86 -> 5177.92 : 1.10x speedup image t-firefox-fishtank 4816.44 -> 4413.95 : 1.09x speedup image t-gnome-system-monitor 6027.70 -> 5638.57 : 1.07x speedup image t-midori-zoomed 2086.73 -> 1952.16 : 1.07x speedup image t-firefox-canvas-alpha 3961.64 -> 3767.66 : 1.05x speedup -- Best regards, Siarhei Siamashka _______________________________________________ Pixman mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pixman
