bool "ACPI Processor Enumeration for HT"
depends on (X86 && X86_LOCAL_APIC)
default y
---help---
ACPI enumerates both logical (a.k.a. Hyper-Threaded -- HT)
and physical processors. It is designed to obsolete several older
specifications, including the MultiProcessor Specification (MPS),
which supported only physical processors.
CONFIG_ACPI_HT includes the minimal ACPI boot-time code
necessary to enumerate logical processors and enable HT.
CONFIG_ACPI includes CONFIG_ACPI_HT, plus IO APIC enumeration,
and the hooks to run the ACPI AML interpreter for run-time events.
When CONFIG_ACPI is selected, the command-line option "acpi=ht"
is available to run just the ACPI boot-time code -- just as if
only CONFIG_ACPI_HT were selected.
Note that "acpi=off" can be used to disable all ACPI code in the kernel.

This option enables limited ACPI support -- just enough to
enumerate processors from the ACPI Multiple APIC Description
Table (MADT). Note that ACPI supports both logical (e.g. Hyper-
Threading) and physical processors, where the MultiProcessor
Specification (MPS) table only supports physical processors.
Full ACPI support (CONFIG_ACPI) is preferred. Use this option
only if you wish to limit ACPI's role to processor enumeration.
In this configuration, ACPI defaults to off. It must be enabled
on the command-line with the "acpismp=force" option.
