Use this new instruction introduced in Gen12. The instruction itself is smaller, and it also allows us to emit a single instruction to all stages that have the same push constant buffers (e.g. when they don't have constant buffers). There's one restriction to use this instruction, though: the length field is only 5 bits long, so we need to check whether we can use it, and fallback to the old 3DSTATE_CONSTANT_XS if that field is >= 32. v2: - Rebased on top of the lasted changes from Jason. - Added review suggestions by Caio. - Removed struct push_bos and merged some code into anv_nir_compute_push_layout(). v3: - Remove code churn due to gen8+ workaround in anv_nir_compute_push_layout(). This code has been removed in an earlier commit, and implemented in cmd_buffer_emit_push_constant(). Reviewed-by: Caio Marcelo de Oliveira Filho <caio.oliveira@intel.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.
