Original patches wrote by Ella Stanforth.
Alejandro Piñeiro main changes (skipping the small fixes/typos):
* Reduced the list of supported formats to
VK_FORMAT_G8_B8_R8_3PLANE_420_UNORM and
VK_FORMAT_G8_B8R8_2PLANE_420_UNORM, that are the two only
mandatory by the spec.
* Fix format features exposed with YCbCr:
* Disallow some features not supported with YCbCr (like blitting)
* Disallow storage image support. Not clear if really useful. Even
if there are CTS tests, there is an ongoing discussion about the
possibility to remove them.
* Expose VK_FORMAT_FEATURE_COSITED_CHROMA_SAMPLES_BIT, that is
mandatory for the formats supported.
* Not expose VK_FORMAT_FEATURE_2_MIDPOINT_CHROMA_SAMPLES_BIT. Some
CTS tests are failing right now, and it is not mandatory. Likely
to be revisit later.
* We are keeping VK_FORMAT_FEATURE_2_DISJOINT_BIT and
VK_FORMAT_FEATURE_2_MIDPOINT_CHROMA_SAMPLES_BIT. Even if they
are optional, it is working with the two formats that we are
exposing. Likely that will need to be refined if we start to
expose more formats.
* create_image_view: don't use hardcoded 0x70, but instead doing an
explicit bit or of VK_IMAGE_ASPECT_PLANE_0/1/2_BIT
* image_format_plane_features: keep how supported aspects and
separate stencil check is done. Even if the change introduced was
correct (not sure about that though), that change is unrelated to
this work
* write_image_descriptor: add additional checks for descriptor type,
to compute properly the offset.
* Cosmetic changes (don't use // for comments, capital letters, etc)
* Main changes coming from the review:
* Not use image aliases. All the info is already on the image
planes, and some points of the code were confusing as it was
using always a hardcoded plane 0.
* Squashed the two original main patches. YCbCr conversion was
leaking on the multi-planar support, as some support needed
info coming from the ycbcr structs.
* Not expose the extension on Android, and explicitly assert that
we expect plane_count to be 1 always.
* For a full list of review changes see MR#19950

`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.
