Windows 8 policy dictates whether we can use the AML code or not. IMHO, ACPI code is in the best position to figure this out and quirk as necessary. It's the part that knows about Windows 8, not i915. > But I have no way of determining that, whereas you work for a company > that produces a Windows 8 video driver… Here I do see the logic. However see signature; I'm not in the best of positions to figure out things about Windows 8 video drivers. ;) But I'll see what I can do.
