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
---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
---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
---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
select INPUT_POLLDEV
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 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.

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.

config INTEL_INT0002_VGPIO
tristate "Intel ACPI INT0002 Virtual GPIO driver"
depends on GPIOLIB && ACPI
select GPIOLIB_IRQCHIP
---help---
Some peripherals on Bay Trail and Cherry Trail platforms signal a
Power Management Event (PME) to the Power Management Controller (PMC)
to wakeup the system. When this happens software needs to explicitly
clear the PME bus 0 status bit in the GPE0a_STS register to avoid an
IRQ storm on IRQ 9.
This is modelled in ACPI through the INT0002 ACPI device, which is
called a "Virtual GPIO controller" in ACPI because it defines the
event handler to call when the PME triggers through _AEI and _L02
methods as would be done for a real GPIO interrupt in ACPI.
To compile this driver as a module, choose M here: the module will
be called intel_int0002_vgpio.

by hardware agents inside the SoC. Read and write masks can be
defined for:
- eSRAM flush
- Dirty CPU snoop (write only)
- RMU access
- PCI Virtual Channel 0/Virtual Channel 1
