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

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

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