The intent is to provide an easy way to measure the impact of an
optimization, not by measuring the whole workload completion time
but also by measuring certain chunks of the workload like command
buffers, renderpasses, or even separate draws.
A moderate perf win in a rare case may not translate into statistically
signifacant overall result. An optimization also may hurt perf in some
cases and help in other which is also hard to judge from overall perf.
For best results pin cpu/gpu frequencies and disable gpu suspend.
Exclude all unnecessary tracepoints via TU_GPU_TRACEPOINT.
Usage:
u_trace_gather.py gather_all \
--loops 1 --launcher "renderdoccmd replay --loops 12" \
--traces-list /path/to/traces.txt \
--traces-dir /path/to/dir/with/traces/ \
--results /path/to/results/ \
--alias new-shiny-opt
u_trace_compare.py compare \
--results /path/to/results/ \
--loops-merged true \
--alias-a default \
--alias-b new-shiny-opt \
--event-start start_render_pass \
--event-end end_render_pass \
--filter "int(params['drawCount']) > 10"
u_trace_compare.py details \
--results /path/to/results/ \
--trace-name test.rdc \
--alias default \
--event-start start_render_pass \
--event-end end_render_pass

`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>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
