config ACPI_HT
bool "ACPI Processor Enumeration for HT"
depends on X86
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.

of the AC module.
