isam.v is a version of isam that can load multiple components from IBOs. It uses some bits that are used for different purposes in other tex instructions: - bit 50 (.v): .s elsewhere - bit 53 (indicates whether an immediate offset is used): .p elsewhere - bit 18 (.1d when not set, has to be set for .v): 0 elsewhere For this reason, the bitset hierarchy for cat5 had to be reordered a bit. The immediate offset is encoded as an extra (immed) source register and an instruction flag (to be able to make the distinction between offset zero and no offset, although this might not be useful). This also adds a flag for the .1d field. Since this bit is active-low, this flag has inverted semantics: setting it will make .1d inactive. Note that some existing disassembler tests for isam had to be updated because the bit is never set and this is now disassembled as .1d. This matches the blob's disassembler.

`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://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.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 `OFTC's #dri-devel <irc://irc.oftc.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. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
