---help---
This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
support for Fn-Fx key combinations, Bluetooth control, video
output switching, ThinkLight control, UltraBay eject and more.
For more information about this driver see
<file:Documentation/laptops/thinkpad-acpi.txt> and
<http://ibm-acpi.sf.net/> .
This driver was formerly known as ibm-acpi.
Extra functionality will be available if the rfkill (CONFIG_RFKILL)
and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
Note that if you want ThinkPad-ACPI to be built-in instead of
modular, ALSA and rfkill will also have to be built-in.
If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
config THINKPAD_ACPI_ALSA_SUPPORT
bool "Console audio control ALSA interface"
depends on THINKPAD_ACPI
depends on SND
depends on SND = y || THINKPAD_ACPI = SND
default y
---help---
Enables monitoring of the built-in console audio output control
(headphone and speakers), which is operated by the mute and (in
some ThinkPad models) volume hotkeys.
If this option is enabled, ThinkPad-ACPI will export an ALSA card
with a single read-only mixer control, which should be used for
on-screen-display feedback purposes by the Desktop Environment.
Optionally, the driver will also allow software control (the
ALSA mixer will be made read-write). Please refer to the driver
documentation for details.
All IBM models have both volume and mute control. Newer Lenovo
models only have mute control (the volume hotkeys are just normal
keys and volume control is done through the main HDA mixer).
config THINKPAD_ACPI_DEBUGFACILITIES
bool "Maintainer debug facilities"
depends on THINKPAD_ACPI
default n
---help---
Enables extra stuff in the thinkpad-acpi which is completely useless
for normal use. Read the driver source to find out what it does.
Say N here, unless you were told by a kernel maintainer to do
otherwise.
config THINKPAD_ACPI_DEBUG
bool "Verbose debug mode"
depends on THINKPAD_ACPI
default n
---help---
Enables extra debugging information, at the expense of a slightly
increase in driver size.
If you are not sure, say N here.
config THINKPAD_ACPI_UNSAFE_LEDS
bool "Allow control of important LEDs (unsafe)"
depends on THINKPAD_ACPI
default n
---help---
Overriding LED state on ThinkPads can mask important
firmware alerts (like critical battery condition), or misled
the user into damaging the hardware (undocking or ejecting
the bay while buses are still active), etc.
LED control on the ThinkPad is write-only (with very few
exceptions on very ancient models), which makes it
impossible to know beforehand if important information will
be lost when one changes LED state.
Users that know what they are doing can enable this option
and the driver will allow control of every LED, including
the ones on the dock stations.
Never enable this option on a distribution kernel.
Say N here, unless you are building a kernel for your own
use, and need to control the important firmware LEDs.
config THINKPAD_ACPI_VIDEO
bool "Video output control support"
depends on THINKPAD_ACPI
default y
---help---
Allows the thinkpad_acpi driver to provide an interface to control
the various video output ports.
This feature often won't work well, depending on ThinkPad model,
display state, video output devices in use, whether there is a X
server running, phase of the moon, and the current mood of
Schroedinger's cat. If you can use X.org's RandR to control
your ThinkPad's video output ports instead of this feature,
don't think twice: do it and say N here to save memory and avoid
bad interactions with X.org.
NOTE: access to this feature is limited to processes with the
CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
where it interacts badly with X.org.
If you are not sure, say Y here but do try to check if you could
be using X.org RandR instead.
config THINKPAD_ACPI_HOTKEY_POLL
bool "Support NVRAM polling for hot keys"
depends on THINKPAD_ACPI
default y
---help---
Some thinkpad models benefit from NVRAM polling to detect a few of
the hot key press events. If you know your ThinkPad model does not
need to do NVRAM polling to support any of the hot keys you use,
unselecting this option will save about 1kB of memory.
ThinkPads T40 and newer, R52 and newer, and X31 and newer are
unlikely to need NVRAM polling in their latest BIOS versions.
NVRAM polling can detect at most the following keys: ThinkPad/Access
IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
If you are not sure, say Y here. The driver enables polling only if
it is strictly necessary to do so.
config SENSORS_HDAPS
tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
depends on INPUT && X86
select INPUT_POLLDEV
default n
help
This driver provides support for the IBM Hard Drive Active Protection
System (hdaps), which provides an accelerometer and other misc. data.
ThinkPads starting with the R50, T41, and X40 are supported. The
accelerometer data is readable via sysfs.
This driver also provides an absolute input class device, allowing
the laptop to act as a pinball machine-esque joystick.
If your ThinkPad is not recognized by the driver, please update to latest
BIOS. This is especially the case for some R52 ThinkPads.
Say Y here if you have an applicable laptop and want to experience
the awesome power of hdaps.
config INTEL_MENLOW

To compile this driver as a module, choose M here: the module will
be called eeepc-wmi.
config ACPI_WMI
tristate "WMI"
depends on ACPI
help
This driver adds support for the ACPI-WMI (Windows Management
Instrumentation) mapper device (PNP0C14) found on some systems.
ACPI-WMI is a proprietary extension to ACPI to expose parts of the
ACPI firmware to userspace - this is done through various vendor
defined methods and data blocks in a PNP0C14 device, which are then
made available for userspace to call.
The implementation of this in Linux currently only exposes this to
other kernel space drivers.
This driver is a required dependency to build the firmware specific
drivers needed on many machines, including Acer and HP laptops.
It is safe to enable this driver even if your DSDT doesn't define
any ACPI-WMI devices.
config MSI_WMI
tristate "MSI WMI extras"
depends on ACPI_WMI
depends on INPUT

config ACPI_ASUS
tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
depends on ACPI
select BACKLIGHT_CLASS_DEVICE
---help---
This driver provides support for extra features of ACPI-compatible
ASUS laptops. As some of Medion laptops are made by ASUS, it may also
support some Medion laptops (such as 9675 for example). It makes all
the extra buttons generate standard ACPI events that go through
/proc/acpi/events, and (on some models) adds support for changing the
display brightness and output, switching the LCD backlight on and off,
and most importantly, allows you to blink those fancy LEDs intended
for reporting mail and wireless status.
Note: display switching code is currently considered EXPERIMENTAL,
toying with these values may even lock your machine.
All settings are changed via /proc/acpi/asus directory entries. Owner
and group for these entries can be set with asus_uid and asus_gid
parameters.
More information and a userspace daemon for handling the extra buttons
at <http://acpi4asus.sf.net>.
If you have an ACPI-compatible ASUS laptop, say Y or M here. This
driver is still under development, so if your laptop is unsupported or
something works not quite as expected, please use the mailing list
available on the above page (acpi4asus-user@lists.sourceforge.net).
NOTE: This driver is deprecated and will probably be removed soon,
use asus-laptop instead.
config TOPSTAR_LAPTOP
tristate "Topstar Laptop Extras"
depends on ACPI

select LEDS_CLASS
select NEW_LEDS
depends on BACKLIGHT_CLASS_DEVICE
depends on INPUT
depends on RFKILL || RFKILL = n
select INPUT_POLLDEV
select INPUT_SPARSEKMAP
---help---
This driver adds support for access to certain system settings
on "legacy free" Toshiba laptops. These laptops can be recognized by
their lack of a BIOS setup menu and APM support.
On these machines, all system configuration is handled through the
ACPI. This driver is required for access to controls not covered
by the general ACPI drivers, such as LCD brightness, video output,
etc.
This driver differs from the non-ACPI Toshiba laptop driver (located
under "Processor type and features") in several aspects.
Configuration is accessed by reading and writing text files in the
/proc tree instead of by program interface to /dev. Furthermore, no
power management functions are exposed, as those are handled by the
general ACPI drivers.
More information about this driver is available at
<http://memebeam.org/toys/ToshibaAcpiDriver>.
If you have a legacy free Toshiba laptop (such as the Libretto L1
series), say Y.
config TOSHIBA_BT_RFKILL
tristate "Toshiba Bluetooth RFKill switch support"
depends on ACPI
---help---
This driver adds support for Bluetooth events for the RFKill
switch on modern Toshiba laptops with full ACPI support and
an RFKill switch.
This driver handles RFKill events for the TOS6205 Bluetooth,
and re-enables it when the switch is set back to the 'on'
position.
If you have a modern Toshiba laptop with a Bluetooth and an
RFKill switch (such as the Portege R500), say Y.

If unsure, say N.
config RAR_REGISTER
bool "Restricted Access Region Register Driver"
depends on PCI && X86_MRST
default n
---help---
This driver allows other kernel drivers access to the
contents of the restricted access region control registers.
The restricted access region control registers
(rar_registers) are used to pass address and
locking information on restricted access regions
to other drivers that use restricted access regions.
The restricted access regions are regions of memory
on the Intel MID Platform that are not accessible to
the x86 processor, but are accessible to dedicated
processors on board peripheral devices.
The purpose of the restricted access regions is to
protect sensitive data from compromise by unauthorized
programs running on the x86 processor.
config INTEL_IPS
tristate "Intel Intelligent Power Sharing"
depends on ACPI
---help---
Intel Calpella platforms support dynamic power sharing between the
CPU and GPU, maximizing performance in a given TDP. This driver,
along with the CPU frequency and i915 drivers, provides that
functionality. If in doubt, say Y here; it will only load on
supported platforms.
config IBM_RTL

depends on X86 && PCI
---help---
Enable support for IBM Premium Real Time Mode (PRTM).
This module will allow you the enter and exit PRTM in the BIOS via
sysfs on platforms that support this feature. System in PRTM will
not receive CPU-generated SMIs for recoverable errors. Use of this
feature without proper support may void your hardware warranty.
If the proper BIOS support is found the driver will load and create
/sys/devices/system/ibm_rtl/. The "state" variable will indicate
whether or not the BIOS is in PRTM.
