This repository takes care of two things:

• Re-building oibaf's graphics-drivers ppa (nightly mesa from git) with extra patches applied.

  The patches are meant for running Ubuntu 24.04 and 24.10 within a proot environment using Termux on your Android device.

  This should allow for accelated Vulkan and OpenGL (using Zink).

  It will push the patched mesa version to my pesonal ppa: https://launchpad.net/~mastag/+archive/ubuntu/mesa-turnip-kgsl

  Quick steps to get this working, assuming you already have Ubuntu 24.04 with xfce4 setup inside your proot env:

  1. Use this sample script to enter your proot distribution:

     #!/bin/sh
     
     export XDG_RUNTIME_DIR=${TMPDIR}
     
     # Kill open X11 processes
     kill -9 $(pgrep -f "termux.x11") 2>/dev/null
     
     # Enable PulseAudio over Network
     pulseaudio --verbose --start --exit-idle-time=-1 --load="module-native-protocol-tcp auth-ip-acl=127.0.0.1 auth-anonymous=1"
     
     # Prepare termux-x11 session
     termux-x11 :0 -ac -extension MIT-SHM &
     
     # Wait a bit until termux-x11 gets started.
     sleep 2
     
     # Login in PRoot Environment.
     proot-distro login ubuntu --shared-tmp --user username
     

  2. Once logged into your proot distribution, add the ppa and install the updated drivers:

     sudo apt update
     sudo apt install software-properties-common
     sudo add-apt-repository ppa:mastag/mesa-turnip-kgsl
     sudo apt update
     sudo apt dist-upgrade
     

  3. Add the following variables to /etc/environment:

     MESA_LOADER_DRIVER_OVERRIDE=zink
     VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/freedreno_icd.aarch64.json:/usr/share/vulkan/icd.d/freedreno_icd.armv7l.json
     TU_DEBUG=noconform
     

  4. Use this script to start xfce4:

     sudo /etc/init.d/dbus start
     export DISPLAY=:0
     taskset -c 4-7 startxfce4
     

  5. Edit your ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml file and change: vblank_mode from auto to off.

• Building nightly turnip driver releases for use with Android emulators such as Yuzu, Strato, Flycast etc. (big shoutout to @Weab-chan for doing all the work for me). It basicallly builds a vanilla and patched release.

You can find the patches in the: turnip-patches directory. However I also occasionally apply open merge requests, see the following arrays for more information: For the mesa ppa:
