+/* This file is the basis for the ssdt_proc[] variable 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.
+ *
+ * To generate a new ssdt_proc[], run the commands:
+ * cpp -P src/ssdt-proc.dsl > out/ssdt-proc.dsl.i
+ * iasl -ta -p out/ssdt-proc out/ssdt-proc.dsl.i
+ * tail -c +37 < out/ssdt-proc.aml | hexdump -e '" " 8/1 "0x%02x," "\n"'
+ * and then cut-and-paste the output into the src/acpi.c ssdt_proc[]
+ * array.
+ *
+ * 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, ... })
