-Docking / undocking -- /proc/acpi/ibm/dock
-------------------------------------------
-
-Docking and undocking (e.g. with the X4 UltraBase) requires some
-actions to be taken by the operating system to safely make or break
-the electrical connections with the dock.
-
-The docking feature of this driver generates the following ACPI events:
-
-        ibm/dock GDCK 00000003 00000001 -- eject request
-        ibm/dock GDCK 00000003 00000002 -- undocked
-        ibm/dock GDCK 00000000 00000003 -- docked
-
-NOTE: These events will only be generated if the laptop was docked
-when originally booted. This is due to the current lack of support for
-hot plugging of devices in the Linux ACPI framework. If the laptop was
-booted while not in the dock, the following message is shown in the
-logs:
-
-        Mar 17 01:42:34 aero kernel: thinkpad_acpi: dock device not present
-
-In this case, no dock-related events are generated but the dock and
-undock commands described below still work. They can be executed
-manually or triggered by Fn key combinations (see the example acpid
-configuration files included in the driver tarball package available
-on the web site).
-
-When the eject request button on the dock is pressed, the first event
-above is generated. The handler for this event should issue the
-following command:
-
-        echo undock > /proc/acpi/ibm/dock
-
-After the LED on the dock goes off, it is safe to eject the laptop.
-Note: if you pressed this key by mistake, go ahead and eject the
-laptop, then dock it back in. Otherwise, the dock may not function as
-expected.
-
-When the laptop is docked, the third event above is generated. The
-handler for this event should issue the following command to fully
-enable the dock:
-
-        echo dock > /proc/acpi/ibm/dock
-
-The contents of the /proc/acpi/ibm/dock file shows the current status
-of the dock, as provided by the ACPI framework.
-
-The docking support in this driver does not take care of enabling or
-disabling any other devices you may have attached to the dock. For
-example, a CD drive plugged into the UltraBase needs to be disabled or
-enabled separately. See the provided example acpid configuration files
-for how this can be accomplished.
-
-There is no support yet for PCI devices that may be attached to a
-docking station, e.g. in the ThinkPad Dock II. The driver currently
-does not recognize, enable or disable such devices. This means that
-the only docking stations currently supported are the X-series
-UltraBase docks and "dumb" port replicators like the Mini Dock (the
-latter don't need any ACPI support, actually).
-
-
-UltraBay eject -- /proc/acpi/ibm/bay
-------------------------------------
-
-Inserting or ejecting an UltraBay device requires some actions to be
-taken by the operating system to safely make or break the electrical
-connections with the device.
-
-This feature generates the following ACPI events:
-
-        ibm/bay MSTR 00000003 00000000 -- eject request
-        ibm/bay MSTR 00000001 00000000 -- eject lever inserted
-
-NOTE: These events will only be generated if the UltraBay was present
-when the laptop was originally booted (on the X series, the UltraBay
-is in the dock, so it may not be present if the laptop was undocked).
-This is due to the current lack of support for hot plugging of devices
-in the Linux ACPI framework. If the laptop was booted without the
-UltraBay, the following message is shown in the logs:
-
-        Mar 17 01:42:34 aero kernel: thinkpad_acpi: bay device not present
-
-In this case, no bay-related events are generated but the eject
-command described below still works. It can be executed manually or
-triggered by a hot key combination.
-
-Sliding the eject lever generates the first event shown above. The
-handler for this event should take whatever actions are necessary to
-shut down the device in the UltraBay (e.g. call idectl), then issue
-the following command:
-
-        echo eject > /proc/acpi/ibm/bay
-
-After the LED on the UltraBay goes off, it is safe to pull out the
-device.
-
-When the eject lever is inserted, the second event above is
-generated. The handler for this event should take whatever actions are
-necessary to enable the UltraBay device (e.g. call idectl).
-
-The contents of the /proc/acpi/ibm/bay file shows the current status
-of the UltraBay, as provided by the ACPI framework.
-
-EXPERIMENTAL warm eject support on the 600e/x, A22p and A3x (To use
-this feature, you need to supply the experimental=1 parameter when
-loading the module):
-
-These models do not have a button near the UltraBay device to request
-a hot eject but rather require the laptop to be put to sleep
-(suspend-to-ram) before the bay device is ejected or inserted).
-The sequence of steps to eject the device is as follows:
-
-        echo eject > /proc/acpi/ibm/bay
-        put the ThinkPad to sleep
-        remove the drive
-        resume from sleep
-        cat /proc/acpi/ibm/bay should show that the drive was removed
-
-On the A3x, both the UltraBay 2000 and UltraBay Plus devices are
-supported. Use "eject2" instead of "eject" for the second bay.
-
-Note: the UltraBay eject support on the 600e/x, A22p and A3x is
-EXPERIMENTAL and may not work as expected. USE WITH CAUTION!
