The purpose of this change is to support bg color fill + studio range output. Now, studio range conversion will be done in the gamma block before bg color fill. That is for all studio range outputs adn SDR outputs we will be in NL before blend block. For full range HDR (full range PQ of FP16 only), we will be linear before blend block. - Added linear_0_1 gamma function - Consolidated x_scale and y_scale - Refactor Regam/Degam Funcs - Add y bias to regam and degam - Pull memory allocation for cm into a different function to make it more readable - Added logic to degamma/regamma to re-calculate instead of using table if the scale factors are not one and the bias is not zero. - Changing output gamma programming sequence in sw layer - Fixes in hw layer for interpolation error assocaites with studio range transformation in gamma. - Disabling ocsc - PQ studio will still be 'blended' in NL. But A check was added to reject the job if it is not opaque Reviewed-by: Roy Chan <Roy.Chan@amd.com> Acked-by: Alan Liu <haoping.liu@amd.com> Signed-off-by: Jesse Agate <Jesse.Agate@amd.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/26841> |

`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://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://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://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
