Xe2 has 2 requirements for preferred SLM size: - this value needs to be >= then SLM size - this value must be less than shared SLM/L1$ RAM in the sub-slice of platform Also Xe2 don't have the special '0' encode that sets preferred SLM allocation size to the maximum supported. So here setting a value that is equal or larger than SLM size. It was always setting SLM_ENCODES_128K for LNL A0 stepping probably because of Wa_16018610683 but this restriction applies to all Xe2 platforms, also because of the first restriction mentioned here this workaround is not being properly implemented, will fix that in the next patch. We should have a formula to calculate a preferred SLM allocation size for gfx125 and Xe2 platfoms but until that this is enough to fix at least the applications and tests below on LNL: - GFXBench Aztec Ruins VK - GravityMark VK - Wildlife Extreme VK - 5 crucible tests Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/28910> |

`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 $ 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://docs.mesa3d.org/bugs.html>`_).
