This option enables the use of ACPI tables for obtaining various This option enables limited ACPI support -- just enough to

Threading) and physical processors, where the MultiProcessor
ACPI tables supercede legacy BIOS interfaces. For example, the Specification (MPS) table only supports physical processors.
Multiple APIC Description Table (MADT) defined by the ACPI
Specification is a replacement for the MP Configuration Table
defined by the MultiProcessor Specification (MPS).
You can disable this feature on IA32 systems by adding "acpi_boot=off"
to your kernel command line. (Try "man bootparam" or see the
documentation of your boot loader about how to pass options to the
kernel at boot time.)
IA64 systems do not support legacy BIOS interfaces and thus rely
on ACPI tables to boot the system. No kernel command line options
are supported.
CONFIG_ACPI_INTERPRETER
The ACPI Interpreter (a.k.a. ACPI Core Subsystem) provides the
fundamental services required to parse the ACPI namespace, evaluate
control methods, and manage ACPI hardware and events. This
subsystem exposes kernel interfaces allowing higher level software
to manipulate ACPI defined hardware and software interfaces.
Add "acpi=off" to the kernel command line to disable this feature.
(Try "man bootparam" or see the documentation of your boot loader
about how to pass options to the kernel at boot time.)
Note that this option will enlarge your kernel by about 100K. Full ACPI support (CONFIG_ACPI) is preferred. Use this option
only if you wish to limit ACPI's role to processor enumeration.
CONFIG_ACPI_BUS There is no command-line option to disable this, but the kernel
