VIM3/3L Enable Panfrost
For Ubuntu 24.04 only.
The default release images for VIM4/3/3L/1S with 5.15 kernel and Edge2 with 6.1 kernel are shipped with
close source code of Mali GPU userspace drivers, this documentation will guide you to enable the open source GPU driver of Panfrost.
Enable Panfrost
You need to enable the Panfrost via device tree overlay.
VIM4/3/3L/1S
Add panfrost to node fdt_overlays=:
fdt_overlays=panfrost
Edge2
Add panthor-gpu to node fdt_overlays=:
fdt_overlays=panthor-gpu
For Edge2, you need extra steps to upgrade mesa packages to support Panfrost:
$ cat <<-EOF | sudo tee /etc/apt/sources.list.d/kisaku-panfork-mesa-noble.list deb https://ppa.launchpadcontent.net/kisak/kisak-mesa/ubuntu noble main # deb-src deb https://ppa.launchpadcontent.net/kisak/kisak-mesa/ubuntu noble main EOF $ wget https://raw.githubusercontent.com/khadas/fenix/refs/heads/master/config/panfork-kisak.key $ cat panfork-kisak.key | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/panfork-kisak.gpg $ sudo apt update $ sudo apt -y upgrade $ sudo apt -y install libegl-mesa0 libgbm1 libglapi-mesa libglx-mesa0
Remove the close source GPU libraries
If you want to use the open source GPU driver you need to remove the close source GPU libraries.
sudo apt -y remove linux-gpu-mali-wayland sudo apt -y reinstall libegl1 libgles2 libegl1-mesa-dev libgles2-mesa-dev libglvnd-dev libgles1 libwayland-dev mesa-common-dev libgl-dev libegl-dev libgles-dev libgbm-dev libgbm1 libwayland-egl1 sync sudo reboot
