It's a bit hard to exactly map our implementation to the limits described by Vulkan. The bindless surface handle in the extended message descriptors is 20 bits and it's an index into the table of RENDER_SURFACE_STATE structs that starts at bindless surface base address. This means that we can have at must 1M surface states allocated at any given time. Since most image views take two descriptors, this means we have a limit of about 500K image views. However, since we allocate surface states at vkCreateImageView time, this means our limit is actually something on the order of 500K image views allocated at any time. The actual limit describe by Vulkan, on the other hand, is a limit of how many you can have in a descriptor set. Assuming anyone using 1M descriptors will be using the same image view twice a bunch of times (or a bunch of null descriptors), we can safely advertise a larger limit. 1M is what's required by D3D12, so let's advertise that.

`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 `Freenode's #dri-devel <irc://chat.freenode.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.
