This command allows programming custom pixel hashing tables controlling the balancing of load across pixel pipes. Rather confusingly 3DSTATE_SLICE_TABLE_STATE_POINTERS was serving the same purpose on Gen11: A pixel is mapped to the pixel pipe with index specified by the entry in the table corresponding to the LSBs of the pixel coordinates [Yes you read right the entries are neither subslice nor slice indices!]. Either a 2-way or a 3-way table can be programmed based on whether the platform has two or three pixel pipes per slice. In addition the 16x8 tables defined below can hold two separate 8x8 tables when in DUAL_TABLE mode (which AFAIA is only useful for platforms with multiple asymmetric slices -- I.e. no production platforms as of today to my knowledge).

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.
