| /* 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, ... }) |
