This contains a PKGBUILD and prebuilt versions of mesa for Arch Linux ARM on the PineNote, modified to support the rockchip_ebc eink driver for panfrost GPU acceleration.
The origin of the PKGBUILD is the Arch Linux for ARM PKGBUILD Repository
You need to enable the GPU in the kernel device tree first. Here is information on how to do that. No u-boot modifications were necessary in my case.
For pre-built packages check the releases page.
From mesa release 22.1.6-1 on the supported ebc driver is smaeul's rockchip-ebc instead of pgwipeout's rockchip_ebc. To restore support for rockchip_ebc just link /usr/lib/dri/rockchip_ebc_dri.so to the new /usr/lib/dri/rockchip-ebc_dri.so.
Koreader does not provide an Archlinux-build, so I used debtap to convert the latest .deb to an Archlinux-package.
My sway config, mostly customizations on window representation, grayscale compatibility and touch functionality using waybar.
Files in sway/config belong in ~/.config and files in sway/local belong in ~/.local.
To automatically start sway I used autologin, but because I had issues with missing environment I used commit ba01e1630742c08d81a8d8a6dd961080c90bc63b. For some reason sourcing the environment was removed afterwards.
Install the required programs with:
sudo pacman -S sway swayidle polkit-gnome network-manager-applet alacritty ttf-dejavu ttf-font-awesome light imv wtype
and the AUR programs:
swaylock-fancy squeekboard ulauncher waybar-git
(waybar-git until my battery-compatibility patch arrives in the community package)
I use imv for the fullscreen image and light for backlight control.
Put before_sleep.sh and after_resume.sh in .local/bin, set executable flag and use something like the following swayidle command:
swayidle timeout 600 "systemctl suspend" before-sleep "~/.local/bin/before_sleep.sh" after-resume "~/.local/bin/after_resume.sh"
Change the image path to an existing picture on your device. To give my user account access to the backlight I created udev rules backlight.rules and added my user to the video group.
Firefox disables hardware acceleration by default on aarch64, to enable it set MOZ_ENABLE_WAYLAND=1 in your environment to run Firefox in native Wayland mode, then set gfx.webrender.all to true in about:config. about:support should now show WebRender under Compositing, instead of WebRender (Software).
