Hello, I'm using Mesa's software renderer for the purposes of regression testing in our graphics software. We render various scenes, save a screencap of the framebuffer for each scene, then compare those framebuffer captures to previously known-good captures.
Across runs of these tests on the same hardware, the results seem to be 100% identical. When running the same tests on a different machine, results are *slightly* different. It's very similar within a small tolerance, so this is still usable. However, I was hoping for fully deterministic behavior, even if the hardware is slightly different. Are there some compile time settings or some code that I can change to get Mesa's llvmpipe renderer/rasterizer to be fully deterministic in its output? I'm using llvmpipe, and these are the two different CPUs I'm using to run the tests: Intel(R) Xeon(R) CPU E3-1275 v3 Intel(R) Xeon(R) CPU X5650 Thanks, Andrew _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
