Garrett: ACPI, kernels and contracts with firmware

Matthew Garrett writes about the challenges faced by the developers working on ACPI-based ARM systems. "Somebody is going to need to take responsibility for tracking ACPI behaviour and incrementing the exported interface whenever it changes, and we need to know who that's going to be before any of these systems start shipping. The alternative is a sea of ARM devices that only run specific kernel versions, which is exactly the scenario that ACPI was supposed to be fixing."
