+/* 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, ... })
