This commit ports instruction latency information found in codegen emitter. Previously every instruction was delayed by 16 cycles even if it was not necessary. PixMark Piano is highly affected by instruction latencies and gets a 2.5x boost, other benchmarks still get better performance. The other two missing pieces to get feature parity with codegen are functional unit resource tracking and instruction dual-issue. Performance measures on a GT770 (with 0f pstate) Pixmark piano: 519 -> 14526 pts (has rendering issues in both!) Furmark: 3247 -> 5786 pts The talos principle (high settings): 30-33 -> 55-60 FPS Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/35821> |

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://docs.mesa3d.org/bugs.html>`_).
