firmware that such a driver is present, and modifies how the ThinkPad

firmware will behave in many situations.
|

|
||||
The driver enables the hot key feature automatically when loaded. The
|
||||
feature can later be disabled and enabled back at runtime. The driver
|
||||
will also restore the hot key feature to its previous state and mask
|
||||
when it is unloaded.
|
||||
|
||||
When the hotkey feature is enabled and the hot key mask is set (see
|
||||
below), the various hot keys either generate ACPI events in the

||||
following format:

below), the driver will report HKEY events in the following format:
|
||||
|
||||
ibm/hotkey HKEY 00000080 0000xxxx
|
||||
|
||||
or events over the input layer. The input layer support accepts the
|
||||
standard IOCTLs to remap the keycodes assigned to each hotkey.
|
||||
Some of these events refer to hot key presses, but not all.
|
||||
|
||||
When the input device is open, the driver will suppress any ACPI hot key
|
||||
events that get translated into a meaningful input layer event, in order
|
||||
to avoid sending duplicate events to userspace. Hot keys that are
|
||||
mapped to KEY_RESERVED in the keymap are not translated, and will always
|
||||
generate an ACPI ibm/hotkey HKEY event, and no input layer events.
|
||||
The driver will generate events over the input layer for hot keys and
|
||||
radio switches, and over the ACPI netlink layer for other events. The
|
||||
input layer support accepts the standard IOCTLs to remap the keycodes
|
||||
assigned to each hot key.
|
||||
|

The hot key bit mask allows some control over which hot keys generate

|
||||
|
||||
The above events are not propagated by the driver, except for legacy
|
||||
compatibility purposes when hotkey_report_mode is set to 1.
|
||||
|
||||
Compatibility notes:
|
||||
|
||||
ibm-acpi and thinkpad-acpi 0.15 (mainline kernels before 2.6.23) never
|
||||
supported the input layer, and sent events over the procfs ACPI event
|
||||
interface.
|
||||
|
||||
To avoid sending duplicate events over the input layer and the ACPI
|
||||
event interface, thinkpad-acpi 0.16 implements a module parameter
|
||||
(hotkey_report_mode), and also a sysfs device attribute with the same
|
||||
name.
|
||||
|
||||
Make no mistake here: userspace is expected to switch to using the input
|
||||
layer interface of thinkpad-acpi, together with the ACPI netlink event
|
||||
interface in kernels 2.6.23 and later, or with the ACPI procfs event
|
||||
interface in kernels 2.6.22 and earlier.
|
||||
|
||||
If no hotkey_report_mode module parameter is specified (or it is set to
|
||||
zero), the driver defaults to mode 1 (see below), and on kernels 2.6.22
|
||||
and earlier, also allows one to change the hotkey_report_mode through
|
||||
sysfs. In kernels 2.6.23 and later, where the netlink ACPI event
|
||||
interface is available, hotkey_report_mode cannot be changed through
|
||||
sysfs (it is read-only).
|
||||
|
||||
If the hotkey_report_mode module parameter is set to 1 or 2, it cannot
|
||||
be changed later through sysfs (any writes will return -EPERM to signal
|
||||
that hotkey_report_mode was locked. On 2.6.23 and later, where
|
||||
hotkey_report_mode cannot be changed at all, writes will return -EACES).
|
||||
|
||||
hotkey_report_mode set to 1 makes the driver export through the procfs
|
||||
ACPI event interface all hot key presses (which are *also* sent to the
|
||||
input layer). This is a legacy compatibility behaviour, and it is also
|
||||
the default mode of operation for the driver.
|
||||
|
||||
hotkey_report_mode set to 2 makes the driver filter out the hot key
|
||||
presses from the procfs ACPI event interface, so these events will only
|
||||
be sent through the input layer. Userspace that has been updated to use
|
||||
the thinkpad-acpi input layer interface should set hotkey_report_mode to
|
||||
2.
|
||||
|
||||
Hot key press events are never sent to the ACPI netlink event interface.
|
||||
Really up-to-date userspace under kernel 2.6.23 and later is to use the
|
||||
netlink interface and the input layer interface, and don't bother at all
|
||||
with hotkey_report_mode.
