/* 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, ... }) */ DefinitionBlock ("ssdt-proc.aml", "SSDT", 0x01, "BXPC", "BXSSDT", 0x1) /* v------------------ DO NOT EDIT ------------------v */ { Processor (CPAA, 0xAA, 0x0000b010, 0x06) { Name (ID, 0xAA) /* ^------------------ DO NOT EDIT ------------------^ * * The src/acpi.c code requires the above layout so that it can update * CPAA and 0xAA with the appropriate CPU id (see * SD_OFFSET_CPUHEX/CPUID1/CPUID2).
