Linux 7.0.0-sky1 — Custom Kernel for Radxa Orion O6

A custom Linux kernel for the Radxa Orion O6 board, based on the CIX Sky1 SoC (ARM64).

This kernel is designed to work with edk2-cix-unlocked, an unlocked UEFI firmware for the Orion O6. This kernel boots with ACPI-only currently (no Device Tree support).

Building

Apply the default config

make defconfig sky1_defconfig

The defconfig is located at arch/arm64/configs/sky1_defconfig.

Build the kernel

make -j$(nproc) all

Build the DKMS drivers

The mali_kbase GPU, aipu NPU, VPU kernel modules is packaged separately as a DKMS package. See the releases for pre-built packages The installed packages will place dkms src code under /usr/src/ and can be built with for example:

sudo dkms build -m cix-gpu-kmd/1.0.0 -k 7.0.0-sky1

sudo dkms install -m cix-gpu-kmd/1.0.0 -k 7.0.0-sky1

Pre-built Packages

Pre-built packages are available under the Releases tab:

• .pkg.tar.zst packages — for Arch Linux installations with pacman
• Arch Linux image — a ready-to-use Arch Linux installation with the kernel and packages already installed, running xfce4 on Wayland can be found here: https://pixeldrain.com/u/2MLsD8ND

Hardware Support

Working

• GPU (Mali, integrated) — works under Wayland
• USB
• NVMe / Storage
• Networking (Ethernet)
• PCIe
• Display output (DisplayPort)
• CPU frequency scaling
• Audio (HDA)

Not Working

• Hardware cursor / overlay planes — causes GPU firmware crash; use WLR_NO_HARDWARE_CURSORS=1 and WLR_SCENE_DISABLE_DIRECT_SCANOUT=1 under wlroots-based compositors

Notes

• If you want to use a NVIDIA discrete GPU then first start up the installation without the GPU installed, install lightdm and a greeter, configure lightdm how you want it, then disable SDDM and enable lightdm with systemctl. This is the easiest way to get it working without issues. SDDM is configured to use wayland and will default to using the inegrated GPU which will crash nvidia-drm if a GPU is installed.
