/* This file is the basis for the ssdt table generated in src/acpi.c.
* It defines the contents of the per-cpu Processor() object. At
* runtime, a dynamically generated SSDT will contain one copy of this
* AML snippet for every possible cpu in the system. The objects will
* be placed in the \_SB_ namespace.
*
* In addition to the aml code generated from this file, the
* src/acpi.c file creates a NTFY method with an entry for each cpu:
* Method(NTFY, 2) {
* If (LEqual(Arg0, 0x00)) { Notify(CP00, Arg1) }
* If (LEqual(Arg0, 0x01)) { Notify(CP01, Arg1) }
* ...
* }
* and a CPON array with the list of active and inactive cpus:
* Name(CPON, Package() { One, One, ..., Zero, Zero, ... })
