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

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

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