It's an alternative approach to 1) [PATCH hack dontapply v2 0/7] Dynamic _CST generation which instead of dynamic AML loading uses static AML with dynamic values. It allows us to keep firmware blob static and to avoid split firmware issue (1) in case of cross version migration.
ABI in this case is confined to cpu hotplug IO registers (i.e. do it old school way, like we used to do so far). This way we don't have to add yet another ABI to keep dynamic AML code under control (1). Tested with: XPsp3 - ws2106 guests. CC: "Michael S.
