+ bool "ACPI (Advanced Configuration and Power Interface) Support"
+ depends on !IA64_HP_SIM
+ depends on IA64 || X86
+ depends on PCI
+ select PNP
+ default y
+ help
+ 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, ACPI is used.
+
+ The project home page for the Linux ACPI subsystem is here:
+ <http://www.lesswatts.org/projects/acpi/>
+
+ Linux support for ACPI is based on Intel Corporation's ACPI
+ Component Architecture (ACPI CA). For more information on the
+ ACPI CA, see:
+ <http://acpica.org/>
+
+ ACPI is an open industry specification co-developed by
+ Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba.
+ The specification is available at:
+ <http://www.acpi.info>

+ bool
+ depends on SUSPEND || HIBERNATION
+ default y
+
+config ACPI_PROCFS
+ bool "Deprecated /proc/acpi files"
+ depends on PROC_FS
+ help
+ For backwards compatibility, this option allows
+ deprecated /proc/acpi/ files to exist, even when
+ they have been replaced by functions in /sys.
+
+ This option has no effect on /proc/acpi/ files
+ and functions which do not yet exist in /sys.
+
+ Say N to delete /proc/acpi/ files that have moved to /sys/
+
+config ACPI_PROCFS_POWER
+ bool "Deprecated power /proc/acpi directories"
+ depends on PROC_FS
+ help
+ For backwards compatibility, this option allows
+ deprecated power /proc/acpi/ directories to exist, even when
+ they have been replaced by functions in /sys.
+ The deprecated directories (and their replacements) include:
+ /proc/acpi/battery/* (/sys/class/power_supply/*)
+ /proc/acpi/ac_adapter/* (sys/class/power_supply/*)
+ This option has no effect on /proc/acpi/ directories
+ and functions, which do not yet exist in /sys
+ This option, together with the proc directories, will be
+ deleted in 2.6.39.
+
+ Say N to delete power /proc/acpi/ directories that have moved to /sys/
+
+config ACPI_EC_DEBUGFS
+ tristate "EC read/write access through /sys/kernel/debug/ec"
+ default n
+ help
+ Say N to disable Embedded Controller /sys/kernel/debug interface
+
+ Be aware that using this interface can confuse your Embedded
+ Controller in a way that a normal reboot is not enough. You then
+ have to power off your system, and remove the laptop battery for
+ some seconds.
+ An Embedded Controller typically is available on laptops and reads
+ sensor values like battery state and temperature.
+ The kernel accesses the EC through ACPI parsed code provided by BIOS
+ tables. This option allows to access the EC directly without ACPI
+ code being involved.
+ Thus this option is a debug option that helps to write ACPI drivers
+ and can be used to identify ACPI code or EC firmware bugs.
+
+config ACPI_PROC_EVENT
+ bool "Deprecated /proc/acpi/event support"
+ depends on PROC_FS
+ default y
+ help
+ A user-space daemon, acpid, typically reads /proc/acpi/event
+ and handles all ACPI-generated events.
+
+ These events are now delivered to user-space either
+ via the input layer or as netlink events.
+
+ This build option enables the old code for legacy
+ user-space implementation. After some time, this will
+ be moved under CONFIG_ACPI_PROCFS, and then deleted.
+
+ Say Y here to retain the old behaviour. Say N if your
+ user-space is newer than kernel 2.6.23 (September 2007).
+
+config ACPI_AC
+ tristate "AC Adapter"
+ depends on X86
+ select POWER_SUPPLY
+ default y
+ help
+ This driver supports the AC Adapter object, which indicates
+ whether a system is on AC or not. If you have a system that can
+ switch between A/C and battery, say Y.
+
+ To compile this driver as a module, choose M here:
+ the module will be called ac.
+
+config ACPI_BATTERY
+ tristate "Battery"
+ depends on X86
+ select POWER_SUPPLY
+ default y
+ help
+ This driver adds support for battery information through
+ /proc/acpi/battery. If you have a mobile system with a battery,
+ say Y.
+
+ To compile this driver as a module, choose M here:
+ the module will be called battery.
+
+config ACPI_BUTTON
+ tristate "Button"
+ depends on INPUT
+ default y
+ help
+ This driver handles events on the power, sleep, and lid buttons.
+ A daemon reads /proc/acpi/event and perform user-defined actions
+ such as shutting down the system. This is necessary for
+ software-controlled poweroff.
+
+ To compile this driver as a module, choose M here:
+ the module will be called button.
+
+config ACPI_VIDEO
+ tristate "Video"
+ depends on X86 && BACKLIGHT_CLASS_DEVICE && VIDEO_OUTPUT_CONTROL
+ depends on INPUT
+ select THERMAL
+ help
+ This driver implements the ACPI Extensions For Display Adapters
+ for integrated graphics devices on motherboard, as specified in
+ ACPI 2.0 Specification, Appendix B. This supports basic operations
+ such as defining the video POST device, retrieving EDID information,
+ and setting up a video output.
+
+ To compile this driver as a module, choose M here:
+ the module will be called video.
+
+config ACPI_FAN
+ tristate "Fan"
+ select THERMAL
+ default y
+ help
+ This driver supports ACPI fan devices, allowing user-mode
+ applications to perform basic fan control (on, off, status).
+
+ To compile this driver as a module, choose M here:
+ the module will be called fan.
+
+config ACPI_DOCK
+ bool "Dock"
+ depends on EXPERIMENTAL
+ help
+ This driver supports ACPI-controlled docking stations and removable
+ drive bays such as the IBM Ultrabay and the Dell Module Bay.
+
+config ACPI_PROCESSOR
+ tristate "Processor"
+ select THERMAL
+ select CPU_IDLE
+ default y
+ help
+ This driver installs ACPI as the idle handler for Linux and uses
+ ACPI C2 and C3 processor states to save power on systems that
+ support it. It is required by several flavors of cpufreq
+ performance-state drivers.
+
+ To compile this driver as a module, choose M here:
+ the module will be called processor.
+config ACPI_IPMI
+ tristate "IPMI"
+ depends on EXPERIMENTAL && IPMI_SI && IPMI_HANDLER
+ default n
+ help
+ This driver enables the ACPI to access the BMC controller. And it
+ uses the IPMI request/response message to communicate with BMC
+ controller, which can be found on on the server.
+
+ To compile this driver as a module, choose M here:
+ the module will be called as acpi_ipmi.
+
+config ACPI_HOTPLUG_CPU
+ bool
+ depends on ACPI_PROCESSOR && HOTPLUG_CPU
+ select ACPI_CONTAINER
+ default y
+
+config ACPI_PROCESSOR_AGGREGATOR
+ tristate "Processor Aggregator"
+ depends on ACPI_PROCESSOR
+ depends on EXPERIMENTAL
+ depends on X86
+ help
+ ACPI 4.0 defines processor Aggregator, which enables OS to perform
+ specific processor configuration and control that applies to all
+ processors in the platform. Currently only logical processor idling
+ is defined, which is to reduce power consumption. This driver
+ supports the new device.
+
+config ACPI_THERMAL
+ tristate "Thermal Zone"
+ depends on ACPI_PROCESSOR
+ select THERMAL
+ default y
+ help
+ This driver supports ACPI thermal zones. Most mobile and
+ some desktop systems support ACPI thermal zones. It is HIGHLY
+ recommended that this option be enabled, as your processor(s)
+ may be damaged without it.
+
+ To compile this driver as a module, choose M here:
+ the module will be called thermal.
+
+config ACPI_NUMA
+ bool "NUMA support"
+ depends on NUMA
+ depends on (X86 || IA64)

+
+config ACPI_CUSTOM_DSDT_FILE
+ string "Custom DSDT Table file to include"
+ default ""
+ depends on !STANDALONE
+ help
+ This option supports a custom DSDT by linking it into the kernel.
+ See Documentation/acpi/dsdt-override.txt
+
+ Enter the full path name to the file which includes the AmlCode
+ declaration.
+
+ If unsure, don't enter a file name.
+
+config ACPI_CUSTOM_DSDT
+ bool
+ default ACPI_CUSTOM_DSDT_FILE != ""
+
+config ACPI_BLACKLIST_YEAR
+ int "Disable ACPI for systems before Jan 1st this year" if X86_32
+ default 0
+ help
+ Enter a 4-digit year, e.g., 2001, to disable ACPI by default
+ on platforms with DMI BIOS date before January 1st that year.
+ "acpi=force" can be used to override this mechanism.
+
+ Enter 0 to disable this mechanism and allow ACPI to
+ run by default no matter what the year. (default)
+
+config ACPI_DEBUG
+ bool "Debug Statements"
+ default n
+ help
+ The ACPI subsystem can produce debug output. Saying Y enables this
+ output and increases the kernel size by around 50K.
+
+ Use the acpi.debug_layer and acpi.debug_level kernel command-line
+ parameters documented in Documentation/acpi/debug.txt and
+ Documentation/kernel-parameters.txt to control the type and
+ amount of debug output.
+
+config ACPI_DEBUG_FUNC_TRACE
+ bool "Additionally enable ACPI function tracing"
+ default n
+ depends on ACPI_DEBUG
+ help
+ ACPI Debug Statements slow down ACPI processing. Function trace
+ is about half of the penalty and is rarely useful.
+
+config ACPI_PCI_SLOT
+ tristate "PCI slot detection driver"
+ depends on SYSFS
+ default n
+ help
+ This driver creates entries in /sys/bus/pci/slots/ for all PCI
+ slots in the system. This can help correlate PCI bus addresses,
+ i.e., segment/bus/device/function tuples, with physical slots in
+ the system. If you are unsure, say N.
+
+ To compile this driver as a module, choose M here:
+ the module will be called pci_slot.
+
+config X86_PM_TIMER
+ bool "Power Management Timer Support" if EXPERT
+ depends on X86
+ default y
+ help
+ 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 power management 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.
+
+config ACPI_CONTAINER
+ tristate "Container and Module Devices (EXPERIMENTAL)"
+ depends on EXPERIMENTAL
+ default (ACPI_HOTPLUG_MEMORY || ACPI_HOTPLUG_CPU || ACPI_HOTPLUG_IO)
+ help
+ This driver supports ACPI Container and Module devices (IDs
+ ACPI0004, PNP0A05, and PNP0A06).
+
+ This helps support hotplug of nodes, CPUs, and memory.
+
+ To compile this driver as a module, choose M here:
+ the module will be called container.
+
+config ACPI_HOTPLUG_MEMORY
+ tristate "Memory Hotplug"
+ depends on MEMORY_HOTPLUG
+ default n
+ help
+ This driver supports ACPI memory hotplug. The driver
+ fields notifications on ACPI memory devices (PNP0C80),
+ which represent memory ranges that may be onlined or
+ offlined during runtime.
+
+ If your hardware and firmware do not support adding or
+ removing memory devices at runtime, you need not enable
+ this driver.
+
+ To compile this driver as a module, choose M here:
+ the module will be called acpi_memhotplug.
+
+config ACPI_SBS
+ tristate "Smart Battery System"
+ depends on X86
+ select POWER_SUPPLY
+ help
+ This driver supports the Smart Battery System, another
+ type of access to battery information, found on some laptops.
+
+ To compile this driver as a module, choose M here:
+ the modules will be called sbs and sbshc.
+
+config ACPI_HED
+ tristate "Hardware Error Device"
+ help
+ This driver supports the Hardware Error Device (PNP0C33),
+ which is used to report some hardware errors notified via
+ SCI, mainly the corrected errors.
+
+config ACPI_CUSTOM_METHOD
+ tristate "Allow ACPI methods to be inserted/replaced at run time"
+ depends on DEBUG_FS
+ default n
+ help
+ This debug facility allows ACPI AML methods to be inserted and/or
+ replaced without rebooting the system. For details refer to:
+ Documentation/acpi/method-customizing.txt.
+
+ NOTE: This option is security sensitive, because it allows arbitrary
+ kernel memory to be written to by root (uid=0) users, allowing them
+ to bypass certain security measures (e.g. if root is not allowed to
+ load additional kernel modules after boot, this feature may be used
+ to override that restriction).
+
+config ACPI_BGRT
+ tristate "Boottime Graphics Resource Table support"
+ default n
+ help
+ This driver adds support for exposing the ACPI Boottime Graphics
+ Resource Table, which allows the operating system to obtain
+ data from the firmware boot splash. It will appear under
+ /sys/firmware/acpi/bgrt/ .
