Revision af8f3f514d193eb353f9b6cea503c55d074e6153 authored by Hanjun Guo on 04 January 2015, 10:55:02 UTC, committed by Rafael J. Wysocki on 05 January 2015, 22:32:42 UTC
apic_id in MADT table is the CPU hardware id which identify it self in the system for x86 and ia64, OSPM will use it for SMP init to map APIC ID to logical cpu number in the early boot, when the DSDT/SSDT (ACPI namespace) is scanned later, the ACPI processor driver is probed and the driver will use acpi_id in DSDT to get the apic_id, then map to the logical cpu number which is needed by the processor driver. Before ACPI 5.0, only x86 and ia64 were supported in ACPI spec, so apic_id is used both in arch code and ACPI core which is pretty fine. Since ACPI 5.0, ARM is supported by ACPI and APIC is not available on ARM, this will confuse people when apic_id is both used by x86 and ARM in one function. So convert apic_id to phys_id (which is the original meaning) in ACPI processor dirver to make it arch agnostic, but leave the arch dependent code unchanged, no functional change.
