Henrique de Moraes Holschuh a4d5effcc7 thinkpad-acpi: restrict access to some firmware LEDs 
Some of the ThinkPad LEDs indicate critical conditions that can cause
data loss or cause hardware damage when ignored (e.g. force-ejecting
a powered up bay; ignoring a failing battery, or empty battery; force-
undocking with the dock buses still active, etc).

On almost all ThinkPads, LED access is write-only, and the firmware
usually does fire-and-forget signaling on them, so you effectively
lose whatever message the firmware was trying to convey to the user
when you override the LED state, without any chance to restore it.

Restrict access to all LEDs that can convey important alarms, or that
could mislead the user into incorrectly operating the hardware.  This
will make the Lenovo engineers less unhappy about the whole issue.

Allow users that really want it to still control all LEDs, it is the
unaware user that we have to worry about.

select RFKILL
---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.
If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
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_DOCK
bool "Legacy Docking Station Support"
depends on THINKPAD_ACPI
depends on ACPI_DOCK=n
default n
---help---
Allows the thinkpad_acpi driver to handle docking station events.
This support was made obsolete by the generic ACPI docking station
support (CONFIG_ACPI_DOCK). It will allow locking and removing the
laptop from the docking station, but will not properly connect PCI
devices.
If you are not sure, say N here.
config THINKPAD_ACPI_BAY
bool "Legacy Removable Bay Support"
depends on THINKPAD_ACPI
default y
---help---
Allows the thinkpad_acpi driver to handle removable bays. It will
electrically disable the device in the bay, and also generate
notifications when the bay lever is ejected or inserted.
If you are not sure, say Y here.
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 some memory.
If you are not sure, say Y here.
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 INTEL_MENLOW
tristate "Thermal Management driver for Intel menlow platform"
depends on ACPI_THERMAL
select THERMAL
---help---
ACPI thermal management enhancement driver on
Intel Menlow platform.
If unsure, say N.
config EEEPC_LAPTOP
tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
depends on ACPI
depends on INPUT
depends on EXPERIMENTAL
select BACKLIGHT_CLASS_DEVICE
select HWMON
select RFKILL
---help---
This driver supports the Fn-Fx keys on Eee PC laptops.
It also adds the ability to switch camera/wlan on/off.
If you have an Eee PC laptop, say Y or M here.
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 ACPI_ASUS
tristate "ASUS/Medion Laptop Extras"
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://sourceforge.net/projects/acpi4asus/>.
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 ACPI_TOSHIBA
tristate "Toshiba Laptop Extras"
depends on ACPI
depends on INPUT
select INPUT_POLLDEV
select NET
select RFKILL
select BACKLIGHT_CLASS_DEVICE
---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.
