Perfetto requires time in clock snaphots to be monotonic, otherwise the clock would be excluded. GPU timestamps start from zero after every suspend-resume cycle which makes them non-monotonic. As a solution on msm we check whether GPU was just resumed and remember previous highest timestamp to then add it to the next timestamps. If the functionality to get whether gpu is resumed is unavailable or doesn't work - we fallback to a check for a discontinuity in timestamps. For kgsl we always use fallback. Fixes renderstage timeline disappearing in AGI. Or you could avoid the issue altogether by preventing GPU from going to sleep by increasing auto suspend delay e.g.: echo 5000 > /sys/devices/platform/soc\@0/3d00000.gpu/power/autosuspend_delay_ms Signed-off-by: Danylo Piliaiev <dpiliaiev@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/14391> |

`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://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja 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://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
