Valkan (lavapipe) for WSL

This repo (https://github.com/gnsmrky/wsl-vulkan-mesa) is based on mesa 20.3 repo, the 1st official release includes lavapipe. lavapipe is the Vulkan frontend in mesa that uses llvmpipe as software renderer.

The original lavapipe does not support Windows Subsystem for Linux (WSL) in Windows 10. This repo adds workarounds to allow lavapipe to work in WSL and display via VcXsrv.

Prerequisite

1. WSL Ubuntu 18.04.5 or 20.04.1
2. VcXsrv for Windows - Windows X Sever
   This repo uses VcXsrv as Windows X Server on Windows 10. Haven't tested with other X Server alternatives. Pls leave your feedbacks in issues if you reccommend others.
   • Download and install VcXsrv from https://sourceforge.net/projects/vcxsrv/.

Pre-built releases

1. Install required packages

   sudo apt update
   sudo apt install llvm libxcb-randr0 libxcb-shm0 libxcb-xfixes0
   

2. Download tarball binaries from Releases.
3. Extract to ~/mesa-local folder
   • Ubuntu 18.04

     mkdir ~/mesa-local
     tar xzvf wsl-ubuntu1804-vulkan-mesa20.3-20201220.tar.gz -C ~/mesa-local
     

   • Ubuntu 20.04

     mkdir ~/mesa-local
     tar xzvf wsl-ubuntu2004-vulkan-mesa20.3-20201220.tar.gz -C ~/mesa-local
     

4. Follow Instsall mesa and run vulkan tools to install and run vulkan

Build mesa for WSL Ubuntu 18.04 or 20.04

Open WSL with Ubuntu 18.04 or 20.04.

1. Update and install needed packages for development.

   sudo apt update
   
   sudo apt install build-essential git python3-pip pkg-config llvm \
   valgrind vainfo bison flex llvm libdrm-dev libxdamage-dev libx11-dev \
   libx11-xcb-dev libxext-dev libxcb-glx0-dev libxcb-dri2-0-dev \
   libxcb-dri3-dev libxcb-present-dev libxcb-shm0-dev libxshmfence-dev \
   libxxf86vm-dev x11-xserver-utils libxrandr-dev
   

2. Setup python

   • Environment vars

     alias python=python3 &&
     alias pip=pip3 &&
     export PATH=~/.local/bin:$PATH
     

   • Install python3 packages.
     pip install meson ninja cmake mako

3. Get this repo and prepare for build env

   • Get this repo
     git clone https://github.com/gnsmrky/wsl-vulkan-mesa
   • Change directory to the repo and create & change to build folder.

     cd wsl-vulkan-mesa
     mkdir build
     cd build
     

4. In build folder, config & build mesa.

   • This sets the target folder at /usr.

     meson -Dprefix=/usr -Ddri-drivers= -Dglx=dri -Dllvm=enabled \
     -Ddri-driver-path=/usr/local/lib/x86_64-linux-gnu/dri \
     -Dgallium-drivers="swrast" -Dplatforms=x11 -Dosmesa=gallium \
     -Dvulkan-drivers=swrast ..
     

   • Build mesa
     ninja

   • Install mesa to target folder ~/mesa-local.
     DESTDIR=~/mesa-local ninja install

Install mesa and run vulkan tools.

1. Config VcXsrv for vulkan (also applies to OpenGL).

   • Launch VcXsrv on Windows 10. Upon launching, set the following:
     • Select Multiple window.
     • Set Display number to 1.
     • Select Start no client (should be default setting).
     • Disable Native opengl.
   • In WSL, set DISPLAY envar to 1.
     export DISPLAY=:1

2. In WSL, copy mesa build files from ~/mesa-local to /usr folder.
   Warning: This will replace mesa library files in WSL (mesa will be udpated from v20.0.8 to v20.3.0)!
   sudo cp -R ~/mesa-local/usr/* /usr

   • Check the mesa versio after copying files.
     glxinfo -B | grep -i 'version string' | grep Mesa

3. Validate and run Vulkan tools.

   • On WSL Ubuntu 18.04, install vulkan-utils and run vulkaninfo

     sudo apt install vulkan-utils
     vulkaninfo | grep -i deviceName
     

     Returns the following:

     WARNING: lavapipe is not a conformant vulkan implementation, testing use only.
     deviceName     = llvmpipe (LLVM 6.0.0, 256 bits)
     

     • Run vulkan-smoketest.
       

   • On WSL Ubuntu 20.04, install vulkan-tools and run vkcube.

     sudo apt install vulkan-tools
     vulkaninfo | grep -i deviceName
     

     Returns the following:

     error: XDG_RUNTIME_DIR not set in the environment.
     WARNING: lavapipe is not a conformant vulkan implementation, testing use only.
     deviceName     = llvmpipe (LLVM 10.0.0, 256 bits)
     

     • Run vkcube
