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

47 * also updating the C code.
