You should be able to poke fw_cfg in the _STA method. The machine file could search its bus on init (or on machine create notify) and populate a fw_cfg variable to indicate whether it found an applesmc.
I don't think we should access fw_cfg from the AML code. AML code is already too fragile and I think accessing fw_cfg is just going to make it worse.
One can poke at the applesmc directly for detection ...
We should return 0x0B on success, not 0x0F, though.
Method(_STA, 0) {Store(0x10, CMDP) // APPLESMC_READ_CMDStore(CMDP, Local0)If (LEqual(Local0, 0x0c)) {
Also, once you've tickled the CMDP, the SMC internal state is no longer what OS X expects, so it gets all hung up on that later during the boot process. I guess I'll put "gain thorough understanding of the qemu applesmc state machine" on my ToDo list :)
