Adds build instructions and workarounds documentation. Workarounds documentation only has the biggest offenders and there are probably way more in code that need yet to be documented.

KosmicKrisp
|
|
###########
|
|
|
|
KosmicKrisp is a Vulkan conformant implementation for macOS on Apple Silicon
|
|
hardware. It is implemented on top of Metal 4, which requires macOS 26 and up.
|
|
|
|
No iOS support is present as of now. However, iOS was taken into consideration
|
|
during development to support A14 Bionic GPUs and upwards.

|
Building
|
|
********
|
|
|
|
The following build instructions assume Homebrew as the package manager to
|
|
install dependencies. Homebrew homepage https://brew.sh/
|
|
Homebrew install command line:
|
|
|
|
.. code-block:: sh
|
|
|
|
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
|
|
|
|
Terminal restart is recommended after Homebrew installation.
|
|
|
|
Requirements
|
|
============
|
|
|
|
- Xcode and Xcode command line tools
|
|
- Homebrew packages
|
|
- meson (1.9.1+, can also be installed as a Python package)
|
|
- cmake
|
|
- pkg-config
|
|
- libclc
|
|
- llvm
|
|
- spirv-llvm-translator
|
|
|
|
Due to potential conflicts, Homebrew will not add `llvm` to the path. To add
|
|
`llvm` to future terminal instances:
|
|
|
|
.. code-block:: sh
|
|
|
|
echo 'export PATH="/opt/homebrew/opt/llvm/bin:$PATH"' >> ~/.zshrc
|
|
|
|
To add `llvm` to current terminal instance:
|
|
|
|
.. code-block:: sh
|
|
|
|
export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
|
|
|
|
- Python
|
|
- Python packages
|
|
- mako
|
|
- packaging
|
|
- pyyaml
|
|
- meson (1.9.1+, if not installed through Homebrew)
|
|
|
|
Since Homebrew manages the Python environment, it is encouraged to create a
|
|
Python virtual environment and install all packages in that environment. To
|
|
create a Python virtual environment (e.g. ``$HOME/venv_mesa``):
|
|
|
|
.. code-block:: sh
|
|
|
|
python3 -m venv $HOME/venv_mesa
|
|
|
|
To enable a Python virtual environment:
|
|
|
|
.. code-block:: sh
|
|
|
|
source $HOME/venv_mesa/bin/activate
|
|
|
|
Build instructions
|
|
==================
|
|
|
|
Out of tree build directory is recommended.
|
|
|
|
Once all requirements have been installed, the following command line can be
|
|
used to create a debug build:
|
|
|
|
.. code-block:: sh
|
|
|
|
meson setup <path/to/mesa> --buildtype=debug -Dplatforms=macos -Dvulkan-drivers=kosmickrisp -Dgallium-drivers= -Dopengl=false -Dzstd=disabled
|
|
|
|
Metal workarounds
|
|
*****************
|
|
|
|
Different workarounds are applied throughout the project to avoid issues such
|
|
as:
|
|
|
|
- Metal API and Vulkan API discrepancies
|
|
- Metal bugs
|
|
- MSL compiler bugs
|
|
- MSL compiler crashes
|
|
|
|
These workarounds can be found in:
