We implement GLES3.0 instanced rendering with full support for instanced arrays (via instance divisors). To do so, we use the new invocation helpers to invoke a triplet of (1, vertex_count, instance_count), rather than simply (1, vertex_count, 1). We rewrite the attribute handling code into a new pan_instancing.c file which handles both the simple LINEAR case for non-instanced as well as each of the new instancing cases: MODULO (for per-vertex attributes), POT and NPOT divisors. As a side effect, we rework how vertex buffers are handled, duplicating them to be 1:1 with vertex descriptors to simplify instancing code paths dramatically. This might be a performance regression, but this remains to be seen; if so, we can always deduplicate later with some added logic in pan_instancing.c Signed-off-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.com>

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.
