|
|||
------------
|
||||
|
||||
If you are compiling this driver as included in the Linux kernel
|
||||
sources, simply enable the CONFIG_ACPI_IBM option (Power Management /
|
||||
ACPI / IBM ThinkPad Laptop Extras).
|
||||
sources, simply enable the CONFIG_THINKPAD_ACPI option, and optionally
|
||||
enable the CONFIG_THINKPAD_ACPI_BAY option if you want the

thinkpad-specific bay functionality.

|
||||
Features
|
||||
--------
|
||||
|
||||
The driver creates the /proc/acpi/ibm directory. There is a file under
|
||||
that directory for each feature described below. Note that while the
|
||||
driver is still in the alpha stage, the exact proc file format and
|
||||
commands supported by the various features is guaranteed to change
|
||||
frequently.
|
||||
The driver exports two different interfaces to userspace, which can be
|
||||
used to access the features it provides. One is a legacy procfs-based
|
||||
interface, which will be removed at some time in the distant future.
|
||||
The other is a new sysfs-based interface which is not complete yet.
|
||||
|
||||
Driver version -- /proc/acpi/ibm/driver
|
||||
---------------------------------------
|
||||
The procfs interface creates the /proc/acpi/ibm directory. There is a
|
||||
file under that directory for each feature it supports. The procfs
|
||||
interface is mostly frozen, and will change very little if at all: it
|
||||
will not be extended to add any new functionality in the driver, instead
|
||||
all new functionality will be implemented on the sysfs interface.
|
||||
|
||||
The sysfs interface tries to blend in the generic Linux sysfs subsystems
|
||||
and classes as much as possible. Since some of these subsystems are not
|
||||
yet ready or stabilized, it is expected that this interface will change,
|
||||
and any and all userspace programs must deal with it.
|
||||
|
||||
|
||||
Notes about the sysfs interface:
|
||||
|
||||
Unlike what was done with the procfs interface, correctness when talking
|
||||
to the sysfs interfaces will be enforced, as will correctness in the
|
||||
thinkpad-acpi's implementation of sysfs interfaces.
|
||||
|
||||
Also, any bugs in the thinkpad-acpi sysfs driver code or in the
|
||||
thinkpad-acpi's implementation of the sysfs interfaces will be fixed for
|
||||
maximum correctness, even if that means changing an interface in
|
||||
non-compatible ways. As these interfaces mature both in the kernel and
|
||||
in thinkpad-acpi, such changes should become quite rare.
|
||||
|
||||
Applications interfacing to the thinkpad-acpi sysfs interfaces must
|
||||
follow all sysfs guidelines and correctly process all errors (the sysfs
|
||||
interface makes extensive use of errors). File descriptors and open /
|
||||
close operations to the sysfs inodes must also be properly implemented.
|
||||
|
||||
The version of thinkpad-acpi's sysfs interface is exported by the driver
|
||||
as a driver attribute (see below).
|
||||
|
||||
Sysfs driver attributes are on the driver's sysfs attribute space,
|
||||
for 2.6.20 this is /sys/bus/platform/drivers/thinkpad-acpi/.

Most ThinkPad fans work in "levels". Level 0 stops the fan. The higher
|
||||
the level, the higher the fan speed, although adjacent levels often map
|
||||
to the same fan speed. 7 is the highest level, where the fan reaches
|
||||
the maximum recommended speed. Level "auto" means the EC changes the
|
||||
fan level according to some internal algorithm, usually based on
|

readings from the thermal sensors. Level "disengaged" means the EC
|

disables the speed-locked closed-loop fan control, and drives the fan as

fast as it can go, which might exceed hardware limits, so use this level

with caution.

Fan levels:

There is also a "full-speed" level, also known as "disengaged" level.
|
||||
In this level, the EC disables the speed-locked closed-loop fan control,

and drives the fan as fast as it can go, which might exceed hardware

fan commands: "enable", "disable", "level" or "watchdog", or if there

120 seconds. This functionality is called fan safety watchdog.
|

|
||||
Note that the watchdog timer stops after it enables the fan. It will be
|
||||
rearmed again automatically (using the same interval) when one of the
|
||||
above mentioned fan commands is received. The fan watchdog is,
|
||||
therefore, not suitable to protect against fan mode changes made through
|
||||
means other than the "enable", "disable", and "level" procfs fan
|
||||
commands, or the hwmon fan control sysfs interface.

Procfs notes:

Where <level> is an integer from 0 to 7, or one of the words "auto" or

"full-speed" (without the quotes). Not all ThinkPads support the "auto"

compatibility.

2: Hardware PWM control (EC "auto" mode)
|
||||
3: reserved (Software PWM control, not implemented yet)
|

|

Modes 0 and 2 are not supported by all ThinkPads, and the

1 second, maximum is 120 seconds. 0 disables the watchdog.
|
||||
|
||||
To stop the fan: set pwm1 to zero, and pwm1_enable to 1.
|
||||
|
||||
To start the fan in a safe mode: set pwm1_enable to 2. If that fails
|
||||
with EINVAL, try to set pwm1_enable to 1 and pwm1 to at least 128 (255

would be the safest choice, though).

Sysfs interface changelog:
|

|

The ACPI support in the kernel is intended to be used in conjunction
|
||||
with a user-space daemon, acpid. The configuration files for this
|
||||
daemon control what actions are taken in response to various ACPI
|
||||
events. An example set of configuration files are included in the
|
||||
config/ directory of the tarball package available on the web
|
||||
site. Note that these are provided for illustration purposes only and
|
||||
may need to be adapted to your particular setup.
|
||||
|
||||
The following utility scripts are used by the example action
|
||||
scripts (included with ibm-acpi for completeness):
|
||||
|

/usr/local/sbin/idectl -- from the hdparm source distribution,

see http://www.ibiblio.org/pub/Linux/system/hardware
|

/usr/local/sbin/laptop_mode -- from the Linux kernel source

/sbin/service -- comes with Redhat/Fedora distributions
|

Toan T Nguyen <ntt@physics.ucla.edu> notes that Suse uses the
|

powersave program to suspend ('powersave --suspend-to-ram') or
|
||||
hibernate ('powersave --suspend-to-disk'). This means that the
|

hibernate script is not needed on that distribution.
