Advanced Configuration and Power Interface (ACPI) support for
|
|
|
|
|
Linux requires an ACPI compliant platform (hardware/firmware),
|
|
|
|
|
and assumes the presence of OS-directed configuration and power
|
|
|
|
|
management (OSPM) software. This option will enlarge your
|
|
|
|
|
kernel by about 70K.
|
|
|
|
|
|
|
|
|
|
Linux ACPI provides a robust functional replacement for several
|
|
|
|
|
legacy configuration and power management interfaces, including
|
|
|
|
|
the Plug-and-Play BIOS specification (PnP BIOS), the
|
|
|
|
|
MultiProcessor Specification (MPS), and the Advanced Power
|
|
|
|
|
Management (APM) specification. If both ACPI and APM support
|
|
|
|
|
are configured, whichever is loaded first shall be used.
|
|
|
|
|
|
|
|
|
|
The ACPI SourceForge project contains the latest source code,
|
|
|
|
|
documentation, tools, mailing list subscription, and other
|
|
|
|
|
information. This project is available at:

|
|
|
|
<http://sourceforge.net/projects/acpi>
|
|
|
|
|
|
|
|
|
|
Linux support for ACPI is based on Intel Corporation's ACPI
|
|
|
|
|
Component Architecture (ACPI CA). For more information see:

This option adds support for ACPI suspend states.
|
|
|
|
|
|
|
|
|
|
With this option, you will be able to put the system "to sleep".
|
|
|
|
|
Sleep states are low power states for the system and devices. All
|
|
|
|
|
of the system operating state is saved to either memory or disk
|
|
|
|
|
(depending on the state), to allow the system to resume operation
|
|
|
|
|
quickly at your request.
|
|
|
|
|
|
|
|
|
|
Although this option sounds really nifty, barely any of the device
|
|
|
|
|
drivers have been converted to the new driver model and hence few
|
|
|
|
|
have proper power management support.
|
|
|
|
|
|
|
|
|
|
This option is not recommended for anyone except those doing driver
|
|
|
|
|
power management development.

The Power Management Timer is available on all ACPI-capable,

|
|
|
|
in most cases even if ACPI is unusable or blacklisted.

This timing source is not affected by powermanagement features
|
|
|
|
|
like aggressive processor idling, throttling, frequency and/or
|
|
|
|
|
voltage scaling, unlike the commonly used Time Stamp Counter
|

(TSC) timing source.

You should nearly always say Y here because many modern
|
|
|
|
|
systems require this timer.

This can be useful, for example, on NUMA machines that support

ACPI based physical hotplug of nodes, or non-NUMA machines that

support physical cpu/memory hot-plug.

This driver adds supports for ACPI Memory Hotplug. This driver
|
|
|
|
|
provides support for fielding notifications on ACPI memory
|
|
|
|
|
devices (PNP0C80) which represent memory ranges that may be
|
|
|
|
|
onlined or offlined during runtime.
|
|
|
|
|
|
|
|
|
|
Enabling this driver assumes that your platform hardware
|
|
|
|
|
and firmware have support for hot-plugging physical memory. If
|
|
|
|
|
your system does not support physically adding or ripping out
|
|
|
|
|
memory DIMMs at some platfrom defined granularity (individually
|
|
|
|
|
or as a bank) at runtime, then you need not enable this driver.
|
|
|
|
|
|
|
|
|
|
If one selects "m," this driver can be loaded using the following
|
|
|
|
|
command:
|
|
|
|
|
$>modprobe acpi_memhotplug
|
|
|
|
|
endif # ACPI
