Install `meson` (version 52.0 or later):
+ apt-get update -y
apt-get install -y -t buster-backports meson
Then install the necessary packages by running the following commands as root:
apt-get build-dep -y libdrm
apt-get build-dep -y mesa
-Now we are going to build and install `drm` from source as the debian apt versions are not recent enough to build mesa. Run all of these command as a regular user, *DO NOT RUN AS ROOT* it is not necessary.
+Now we are going to build and install `drm` from source as the debian apt versions are not recent enough to build mesa. Run all of these command as a regular user, **DO NOT RUN AS ROOT** it is not necessary.
First, create our working directory `opt` in our user directory. In order to not mess with system `drm` and `mesa` libraries, also create a sub-directory `lsoc_mesa` to hold our header files and libraries. After creating the `opt` directory, cd into it to make it our active, current working directory.
export PKG_CONFIG_PATH=~/opt/lsoc_mesa/lib/x86_64-linux-gnu/pkgconfig/
+These following `vulkan`-specific environment variables are necessary to build our branch of mesa successfully:
+
+ export VK_ICD_FILENAMES=/home/$USER/opt/lsoc_mesa/share/vulkan/icd.d/libresoc_icd.x86_64.json
+ export VK_LOADER_DEBUG=warn
+ export LIBRESOC_TRACE=1
+
Now change back to the base `~/opt` directory and clone the `mesa` git repo from the `mesa` gitlab instance. Change to the `mesa` directory. Create a build directory and cd into it.
cd ~/opt
- git clone https://gitlab.freedesktop.org/mesa/mesa.git
+ git clone https://git.libre-soc.org/git/mesa.git
+ git pull --rebase origin libresoc_dev
+ git checkout -b libresoc_dev
cd mesa
mkdir build && cd build
In order to configure `mesa` for building and installation run the following command. Again, it is *very* important to specify `prefix=/home/$USER/opt/lsoc_mesa` because as mentioned above we need these files for development purposes, but we do not want to corrupt or interfere with our *system* `mesa` libraries.
- meson -Dbuildtype=debug -Dprefix=/home/$USER/opt/lsoc_mesa
+ meson -Dbuildtype=debug -Dprefix=/home/$USER/opt/lsoc_mesa \
+ -Dvulkan-drivers=libre-soc ..
After configuration has completed, run ninja to build and install the `mesa` libraries.
# From here on is solely Vivek's instructions
-I also have script to set few environment variables like
-
- export VK_ICD_FILENAMES=/home/vivek/install/share/vulkan/icd.d/libresoc_icd.x86_64.json
- export VK_LOADER_DEBUG=warn
- export LIBRESOC_TRACE=1
-
To test the code I am sing simple tests built by
+
https://github.com/GameTechDev/IntroductionToVulkan
I am also using debug build for vulkan loader if any one interested in that
previously it was on master so it will cause me problems working on master
branch.
-Also note slight change in meson configure command
-meson -Dbuildtype=debug -Dprefix=/home/vivek/install
--Dvulkan-drivers=libre-soc ..

-instead of libresoc it is libre-soc for vulkan-drivers option.
