Upstreaming:
Open questions:
- The ASL IndexField does not cover all relevant registers, can it be extended somehow?
- Not all registers are exposed via ACPI methods, can they be accessed directly?
- Some registers are exposed via ACPI methods but are not reachable directly from the WMI dispatcher.
- Does ASL have some sort of reflection that could enable those methods?
- Is it possible to call those methods directly, bypassing WMI?
