51 * struct input_absinfo - used by EVIOCGABS/EVIOCSABS ioctls
52 * @value: latest reported value for the axis.
53 * @minimum: specifies minimum value for the axis.
54 * @maximum: specifies maximum value for the axis.
55 * @fuzz: specifies fuzz value that is used to filter noise from
57 * @flat: values that are within this value will be discarded by
58 * joydev interface and reported as 0 instead.
59 * @resolution: specifies resolution for the values reported for
62 * Note that input core does not clamp reported values to the
63 * [minimum, maximum] limits, such task is left to userspace.
65 * Resolution for main axes (ABS_X, ABS_Y, ABS_Z) is reported in
66 * units per millimeter (units/mm), resolution for rotational axes
67 * (ABS_RX, ABS_RY, ABS_RZ) is reported in units per radian.

79 * struct input_keymap_entry - used by EVIOCGKEYCODE/EVIOCSKEYCODE ioctls
80 * @scancode: scancode represented in machine-endian form.
81 * @len: length of the scancode that resides in @scancode buffer.
82 * @index: index in the keymap, may be used instead of scancode
83 * @flags: allows to specify how kernel should handle the request. For
84 * example, setting INPUT_KEYMAP_BY_INDEX flag indicates that kernel
85 * should perform lookup in keymap by @index instead of @scancode
86 * @keycode: key code assigned to this scancode
88 * The structure is used to retrieve and modify keymap data. Users have
89 * option of performing lookup either by @scancode itself or by @index
90 * in keymap entry. EVIOCGKEYCODE will also return scancode or index
91 * (depending on which element was used to perform lookup).

1345 struct input_handle;
1348 * struct input_handler - implements one of interfaces for input devices
1349 * @private: driver-specific data
1350 * @event: event handler. This method is being called by input core with
1351 * interrupts disabled and dev->event_lock spinlock held and so
1353 * @filter: similar to @event; separates normal event handlers from
1355 * @match: called after comparing device's id with handler's id_table
1356 * to perform fine-grained matching between device and handler
1357 * @connect: called when attaching a handler to an input device
1358 * @disconnect: disconnects a handler from input device
1359 * @start: starts handler for given handle. This function is called by
1360 * input core right after connect() method and also when a process
1361 * that "grabbed" a device releases it
1362 * @fops: file operations this driver implements
1363 * @minor: beginning of range of 32 minors for devices this driver
1365 * @name: name of the handler, to be shown in /proc/bus/input/handlers
1366 * @id_table: pointer to a table of input_device_ids this driver can
1368 * @h_list: list of input handles associated with the handler
1369 * @node: for placing the driver onto input_handler_list
1371 * Input handlers attach to input devices and create input handles. There
1372 * are likely several handlers attached to any given input device at the
1373 * same time. All of them will get their copy of input event generated by
1376 * The very same structure is used to implement input filters. Input core
1377 * allows filters to run first and will not pass event to regular handlers
1378 * if any of the filters indicate that the event should be filtered (by
1379 * returning %true from their filter() method).
1381 * Note that input core serializes calls to connect() and disconnect()
