Creating the Mesa Intel Linux driver asset (which supports Vulkan)
|
||
|
|
============================================================
|
||
|
|
|
||
|
|
Using the automated asset python scripts requires that Docker be installed.
|
||
|
|
|
||
|
|
mesa_intel_driver_linux$ python create_and_upload.py
|
||
|
|
|
||
|
|
See below for steps on just building the driver.
|
||
|
|
|
||
|
|
Using Docker
|
||
|
|
------------
|
||
|
|
It is easiest to just use the pre-built docker image.
|
||
|
|
|
||
|
|
docker run -v /tmp/out:/OUT -e MESA_VERSION=18.1.7 gcr.io/skia-public/mesa-driver-builder:latest /opt/build_mesa.sh
|
||
|
|
|
||
|
|
You may change `/tmp/out` to be the desired output directory and `18.1.7` to be the desired
|
||
|
|
version of the mesa driver.
|
||
|
|
|
||
|
|
Finally, use `/tmp/out` as the input directory to the upload script.
|
||
|
|
|
||
|
|
Building it manually
|
||
|
|
--------------------
|
||
|
|
If Docker is not installed, these steps may be used to build the driver.
|
||
|
|
This is known to work on Ubuntu 18.04, but is stale since we use the Docker container
|
||
|
|
for day-to-day builds.
|
||
|
|
|
||
|
|
Install all deps
|
||
|
|
|
||
|
|
sudo apt-get install autoconf libtool scons flex bison llvm-dev libpthread-stubs0-dev x11proto-gl-dev libdrm-dev libdrm2 x11proto-dri2-dev x11proto-dri3-dev x11proto-present-dev libxcb1-dev libxcb-dri3-dev libxcb-present-dev libxshmfence-dev xserver-xorg-core xserver-xorg-dev x11proto-xext-dev libxext-dev libxdamage-dev libx11-xcb-dev libxcb-glx0-dev libxcb-dri2-0-dev libva-dev libomxil-bellagio-dev
|
||
|
|
|
||
|
|
sudo pip install mako
|
||
|
|
|
||
|
|
The following steps are also represented in `mesa-driver-builder/build_mesa.sh`
|
||
|
|
|
||
|
|
Get the source from ftp.freedesktop.org/pub/mesa/
|
||
|
|
|
||
|
|
MESA_VERSION=18.1.7
|
||
|
|
wget ftp://ftp.freedesktop.org/pub/mesa/mesa-$MESA_VERSION.tar.gz
|
||
|
|
gunzip mesa-$MESA_VERSION.tar.gz
|
||
|
|
tar --extract -f mesa-$MESA_VERSION.tar
|
||
|
|
mv mesa-$MESA_VERSION/ mesa
|
||
|
|
cd mesa
|
||
|
|
|
||
|
|
|
||
|
|
Build the driver
|
||
|
|
|
||
|
|
# For the debug resource, use --enable-debug
|
||
|
|
mesa$ ./autogen.sh --disable-radeon --with-gallium-drivers=i915 --with-vulkan-drivers=intel
|
||
|
|
mesa$ make -j 50
|
||
|
|
|
||
|
|
|
||
|
|
Tweak icd.json file and output dir (mesa/lib)
|
||
|
|
|
||
|
|
mesa$ cp src/intel/vulkan/intel_icd.x86_64.json lib/
|
||
|
|
# modify the pathname in the intel_icd.x86_64.json file to be ./libvulkan_intel.so
|
||
|
|
mesa$ rm -rf lib/gallium # We don't need this
|
||
|
|
mesa$ rm lib/nouveau_vieux_dri.so lib/r200_dri.so lib/radeon_dri.so # We don't need these
|
||
|
|
|
||
|
|
Finally, use mesa/lib as the input directory to the upload script.
|
||
|
|
|
||
|
|
|
||
|
|
Docker Image Maintanence
|
||
|
|
------------------------
|
||
|
|
The docker image `mesa-driver-builder` is an Ubuntu container with many build
|
||
|
|
tools installed (including Clang 6). It is designed specifically to build the mesa driver.
|
||
|
|
|
||
|
|
The image only needs to be re-built when the dependencies change or the build_mesa.sh is updated.
|
||
|
|
|
||
|
|
docker build -t mesa-driver-builder ./mesa-driver-builder/
|
||
|
|
# use v1, v2, v3, etc to handle changes/updates to the image.
|
||
|
|
docker tag mesa-driver-builder gcr.io/skia-public/mesa-driver-builder:v1
|
||
|
|
docker push gcr.io/skia-public/mesa-driver-builder:v1
|
