Replace the inline tile_alloc/TSDA sizing in v3dv_job_allocate_tile_state() with a call to the new v3d_tile_alloc_sizes() helper. This switches from 64B to 128B initial tile alloc blocks (avoiding overflow for simple draws) and from a flat 512KB headroom to a draw-proportional formula. Set tile_allocation_initial_block_size and tile_allocation_block_size in all TILE_BINNING_MODE_CFG emissions and update the TILE_LIST_INITIAL_BLOCK_SIZE packets to match. Benchmarked on RPi5 (V3D 7.1) with GfxBench Vulkan Aztec Ruins at 1920x1040. Average tile_alloc BO size dropped 75% (535 KB to 132 KB) with 20% fewer OOM events (521 to 417) and no FPS regression. This avoids exhausting GPU memory when multiple blit or fill jobs are batched in the same command buffer, with a huge reduction of the memory footprint avoiding the 512 KB of the tile_alloc per batched job.

`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>`_).
