Dinput-programming.rst2 Creating an input device driver
8 Here comes a very simple example of an input device driver. The device has
12 #include <linux/input.h>
74 First it has to include the <linux/input.h> file, which interfaces to the
75 input subsystem. This provides all the definitions needed.
81 Then it allocates a new input device structure with input_allocate_device()
82 and sets up input bitfields. This way the device driver tells the other
83 parts of the input systems what it is - what events can be generated or
84 accepted by this input device. Our example device can only generate EV_KEY
94 Then the example driver registers the input device structure by calling::

Dinput.rst12 Input subsystem is a collection of drivers that is designed to support
13 all input devices under Linux. Most of the drivers reside in
14 drivers/input, although quite a few live in drivers/hid and
17 The core of the input subsystem is the input module, which must be
18 loaded before any other of the input modules - it serves as a way of
25 events (keystrokes, mouse movements) to the input module.
30 These modules get events from input core and pass them where needed
