Perfetto's GpuCounterDescriptor exposes a per-counter "groups" field that classifies a counter into well-known buckets (VERTICES, FRAGMENTS, COMPUTE, MEMORY, PRIMITIVES, RAY_TRACING). Tools such as Android CTS' CtsGpuProfilingDataTest#testProfilingDataProducersAvailable iterate the counter specs and union their group lists to determine the set of "supported" GPU counter groups. Until now PPS never populated this field, so all Mesa-backed producers exposed counters with an empty groups list. Add a virtual Driver::classify_counter_groups() hook so each driver can map its own counter naming conventions onto the Perfetto categories without having to include Perfetto headers, then call it from add_descriptors() to emit the per-spec groups field. A neutral CounterGroupType enum is introduced in pps_driver.h and mirrors the values of perfetto::protos::pbzero::GpuCounterDescriptor:: CounterGroup so driver implementations stay decoupled from the Perfetto SDK headers. The default implementation does nothing, leaving counters unclassified for drivers that have not opted in yet. Signed-off-by: Nemallapudi, Jaikrishna <nemallapudi.jaikrishna@intel.com> |

`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.
