16 through the ACPI and ACPI EC framework, but not otherwise fully
17 supported by the generic Linux ACPI drivers.
19 This driver used to be named ibm-acpi until kernel 2.6.21 and release
20 0.13-20070314. It used to be in the drivers/acpi tree, but it was
21 moved to the drivers/misc tree and renamed to thinkpad-acpi for kernel
25 The driver is named "thinkpad-acpi". In some places, like module

89 The procfs interface creates the /proc/acpi/ibm directory. There is a
106 thinkpad-acpi's implementation of sysfs interfaces.
108 Also, any bugs in the thinkpad-acpi sysfs driver code or in the
109 thinkpad-acpi's implementation of the sysfs interfaces will be fixed for
112 in thinkpad-acpi, such changes should become quite rare.

189 In a ThinkPad, the ACPI HKEY handler is responsible for communicating
191 system. Enabling the hotkey functionality of thinkpad-acpi signals the
205 radio switches, and over the ACPI netlink layer for other events. The
212 thinkpad-acpi would prefer to handle it, if the firmware would be so
228 Note also that not all Fn key combinations are supported through ACPI
237 The following commands can be written to the /proc/acpi/ibm/hotkey file::
239 echo 0xffffffff > /proc/acpi/ibm/hotkey -- enable all hot keys
240 echo 0 > /proc/acpi/ibm/hotkey -- disable all possible hot keys
242 echo reset > /proc/acpi/ibm/hotkey -- restore the recommended mask
247 echo enable > /proc/acpi/ibm/hotkey -- does nothing
248 echo disable > /proc/acpi/ibm/hotkey -- returns an error
