Vulkan Sparse resources have their own set of rules, so here we try to make ISL aware of them through ISL_SURF_USAGE_SPARSE_BIT. The big deal here is when some image ends up not using Tile64 nor TileYs. Previously Ys was not supported on TGL at all, and Tile64 did not have support for 3D. Now we still have some formats that end up not being used with either Tile64 and Ys, but need to support Sparse on them (e.g., YUV on Tile64). In the future we may have new tiling formats or hardware restrictions that would force this case to happen again. So here we do some adjustments so we can make sparse work with other tiling formats, although with limited functionality (e.g., those formats may be restricted to opaque binds, and certainly don't support the standard block shapes). v2: before we had Ys support, we had defined TGL's block size as 4k. v3: move the size_B chunk to before nte notify_failure() checks (Ken).

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.
