Add a tool that programs the hardware the minimum amount to be
able to execute compute shaders and then executes a script that
can perform data manipulation and dispatch execution of the shaders
(written in Xe assembly).
The goal is to have a tool to experiment directly with certain
assembly instructions and the shared units without having to
instrument the drivers.
To make more convenient to write assembly, a few macros (indicated by
the @-symbol) will be processed into the full instruction.
For example, the script
```
local r = execute {
data={ [42] = 0x100 },
src=[[
@mov g1 42
@read g2 g1
@id g3
add(8) g4<1>UD g2<8,8,1>UD g3<8,8,1>UD { align1 @1 1Q };
@write g3 g4
@eot
]]
}
dump(r, 4)
```
produces
```
[0x00000000] 0x00000100 0x00000101 0x00000102 0x00000103
```
There's a help message inside the code that describes the script
environment and the macros for assembly sources.

`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 $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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.
