blorp_copy() will soon start changing the format in a way which drivers cannot rely on to do things like manage the texture cache (see iris). Narrow down the scope of blorp_copy_get_formats() and blorp_copy_get_color_format() such that the returned value can only be trusted if compression would be enabled on each image. By doing this (and adapting iris to reflect this), we'll get the required flushes on the platforms which need WaSamplerCacheFlushBetweenRedescribedSurfaceReads: * On the platforms which need the workaround for all formats, blorp_copy() will stick with the queried format on compressed surfaces. * On the platforms which need the workaround when switching from ASTC and non-ASTC formats, blorp_copy() may actually change the queried format on compressed surfaces. This is not a problem, because surfaces which may be read with ASTC formats are not compressible. Prevents gfx9 from failing tests under: * KHR-GL46.copy_image.functional_src_target_texture_2d_array_src_format_r3_g3_b2* * KHR-GL46.copy_image.functional_src_target_texture_2d_array_src_format_rgb5* * KHR-GL46.copy_image.functional_src_target_texture_2d_array_src_format_rgba2* * KHR-GL46.copy_image.functional_src_target_texture_2d_array_src_format_rgba4* Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/39974> |

`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.
