Allocating larger buffers allows KMD/HW to enable optimizations that makes access to memory faster, also because of minimum alignment required in some cases we allocate 4k or 64k long buffers for usages that only needs a few bytes, wasting a lot of memory. Memory pool takes care of both of those things and here I'm adding the base infrastruture to implement this feature. The next patch will implement the functions in anv_slab_bo.c, spliting it in two to make review easier. The idea here is take the same approach as Iris and use pb_slab.h. In 99% of the places it will be transparent that anv_bo is actually a slab of a larger and real anv_bo, the remaning 1% of the places are handled here.

`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.
