When copying data between two surfaces, independently increase the size of each surface's format (bits-per-pixel) as alignment constraints allow. Adjust the other surface parameters and blorp_copy() parameters accordingly. This fixes copies between the 16bpp YCRCB formats and 32bpp formats: dEQP-VK.ycbcr.single_plane_copy.linear.linear.r8g8b8a8_to_g8b8g8r8_422 This new test failure was reported by Iván Briano. More generally, this increases the efficiency of our copies. As shown in the configuration pages of the PRMs, our sampler is able to fetch texels at a fixed rate of texels / clock regardless of the texel size (presumably our rendering hardware has similar behavior). By using the largest texel size possible, we can transfer more bits / clock. Improves the performance of a number of traces in the performance CI for BMG: * TotalWarWarhammer3 +2.24% * Payday3 +1.87% * BaldursGate3 +1.34% * Control +1.25% * TotalWarPharaoh +1.22% Four additional traces are helped between +0.44% and +0.96%.

`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.
