Explore an overview of ACPI support on the Radxa Orion O6 board in this 34-minute technical session. Learn about this mini-ITX motherboard built around the CIX CD8180 12-core Armv9 SoC and its fully functional Linux support including GPU, DPU, VPU, NPU, ISP, USB, PCIe, and all input/output capabilities. Discover how basic system infrastructure and power management features are implemented, including pin control, clock management, reset controllers, memory management, CPU power management, device power management, and suspend to RAM functionality. Understand the challenges faced due to incomplete support in the kernel Arm64 ACPI framework, particularly for standardized implementation in upstream frameworks like clock tree, pinctrl, devfreq, and thermal management. This session highlights the need for community collaboration to accelerate ACPI standardization on Arm-based Client PCs.
