L3 configurations with an ALL partition of 128 ways per bank or more cannot be represented with the normal L3ALLOC partitioning mechanism since the "All L3 client pool" field would overflow, instead the L3FullWayAllocationEnable bit has to be set, which causes the whole L3 to be used in a unified cache configuration. That's precisely the configuration we're currently using on recent platforms, but previously we were relying on the L3 config tables being empty and the selected L3 configuration being a NULL pointer to detect this condition. This is about change, the L3 configuration structure will be defined for gfx12.5+ platforms since they provide useful information about the cache hierarchy to the drivers. Instead of checking whether the pointer is NULL in order to apply a unified L3 cache configuration, use it when there is a single ALL partition larger than can be represented via L3ALLOC.

`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.
