This introduces a representation of the cache coherency status of the GPU at any point in the batch. This is done by defining a matrix C of synchronization sequence numbers such that at any point of batch construction, a memory operation from domain i introduced into the batch is guaranteed to be ordered after any memory operation from domain j in a previous batch section with seqno n if the following condition holds: C_i_j >= n This allows us to efficiently determine whether additional flushing and/or invalidation is required in order to access a buffer object from some arbitrary domain. Except for batch buffer reset which requires clearing the whole matrix, all operations on the matrix are either O(n) or O(1) on the number of caching domains (which is basically constant).

`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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <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.
