We allocate them at the end of the register file and keep them separate from normal VGPRs. This is for two reasons: - Because we only ever move linear VGPRs into an empty space or a space previously occupied by a linear one, we never have to swap a normal VGPR and a linear one. This simplifies copy lowering. - As linear VGPR's live ranges only start and end on top-level blocks, we never have to move a linear VGPR in control flow. fossil-db (navi31): Totals from 5493 (6.93% of 79242) affected shaders: MaxWaves: 150365 -> 150343 (-0.01%) Instrs: 7974740 -> 7976073 (+0.02%); split: -0.06%, +0.08% CodeSize: 41296024 -> 41299024 (+0.01%); split: -0.06%, +0.06% VGPRs: 283192 -> 329560 (+16.37%) Latency: 64267936 -> 64268414 (+0.00%); split: -0.17%, +0.17% InvThroughput: 10954037 -> 10951735 (-0.02%); split: -0.09%, +0.07% VClause: 132792 -> 132956 (+0.12%); split: -0.06%, +0.18% SClause: 223854 -> 223841 (-0.01%); split: -0.01%, +0.01% Copies: 559574 -> 561395 (+0.33%); split: -0.24%, +0.56% Branches: 179630 -> 179636 (+0.00%); split: -0.02%, +0.02% VALU: 4572683 -> 4574487 (+0.04%); split: -0.03%, +0.07% SALU: 772076 -> 772111 (+0.00%); split: -0.01%, +0.01% VOPD: 1095 -> 1099 (+0.37%); split: +0.73%, -0.37% Signed-off-by: Rhys Perry <pendingchaos02@gmail.com> Reviewed-by: Daniel Schürmann <daniel@schuermann.dev> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27697> |

`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://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 `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://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
