> The difference between ARM and x86 is that there's no standardized ARM interface between the motherboard and the CPU—no ARM equivalent to ACPI. Every integration of an ARM CPU into a board is bespoke. So you have to buy "a board with an ARM CPU on it", not just an ARM CPU and board separately. Not exactly true. ARM server chips do have ACPI. The trick is buying a CPU that is SBSA[1] and SBBR[2] compliant. Then most things work as expected.
