48 * @phys: physical path to the device in the system hierarchy
49 * @uniq: unique identification code for the device (if device has it)
50 * @id: id of the device (struct input_id)
51 * @propbit: bitmap of device properties and quirks
52 * @evbit: bitmap of types of events supported by the device (EV_KEY,
53 * EV_REL, etc.)
54 * @keybit: bitmap of keys/buttons this device has
55 * @relbit: bitmap of relative axes for the device
56 * @absbit: bitmap of absolute axes for the device
57 * @mscbit: bitmap of miscellaneous events supported by the device
58 * @ledbit: bitmap of leds present on the device
59 * @sndbit: bitmap of sound effects supported by the device
60 * @ffbit: bitmap of force feedback effects supported by the device
61 * @swbit: bitmap of switches present on the device
62 * @hint_events_per_packet: average number of events generated by the
63 * device in a packet (between EV_SYN/SYN_REPORT events). Used by
64 * event handlers to estimate size of the buffer needed to hold
65 * events.
66 * @keycodemax: size of keycode table
67 * @keycodesize: size of elements in keycode table
68 * @keycode: map of scancodes to keycodes for this device
69 * @getkeycode: optional legacy method to retrieve current keymap.
70 * @setkeycode: optional method to alter current keymap, used to implement
71 * sparse keymaps. If not supplied default mechanism will be used.
72 * The method is being called while holding event_lock and thus must
73 * not sleep
74 * @ff: force feedback structure associated with the device if device
75 * supports force feedback effects
76 * @poller: poller structure associated with the device if device is
77 * set up to use polling mode
78 * @repeat_key: stores key code of the last key pressed; used to implement
79 * software autorepeat
80 * @timer: timer for software autorepeat
81 * @rep: current values for autorepeat parameters (delay, rate)
82 * @mt: pointer to multitouch state
83 * @absinfo: array of &struct input_absinfo elements holding information
84 * about absolute axes (current value, min, max, flat, fuzz,
85 * resolution)
86 * @key: reflects current state of device's keys/buttons
87 * @led: reflects current state of device's LEDs
88 * @snd: reflects current state of sound effects
89 * @sw: reflects current state of device's switches
90 * @open: this method is called when the very first user calls
91 * input_open_device(). The driver must prepare the device
92 * to start generating events (start polling thread,
93 * request an IRQ, submit URB, etc.). The meaning of open() is
94 * to start providing events to the input core.
95 * @close: this method is called when the very last user calls
96 * input_close_device(). The meaning of close() is to stop
97 * providing events to the input core.
98 * @flush: purges the device. Most commonly used to get rid of force
99 * feedback effects loaded into the device when disconnecting
100 * from it
101 * @event: event handler for events sent _to_ the device, like EV_LED
102 * or EV_SND. The device is expected to carry out the requested
103 * action (turn on a LED, play sound, etc.) The call is protected
104 * by @event_lock and must not sleep
105 * @grab: input handle that currently has the device grabbed (via
106 * EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
107 * recipient for all input events coming from the device
108 * @event_lock: this spinlock is taken when input core receives
109 * and processes a new event for the device (in input_event()).
110 * Code that accesses and/or modifies parameters of a device
111 * (such as keymap or absmin, absmax, absfuzz, etc.) after device
112 * has been registered with input core must take this lock.
113 * @mutex: serializes calls to open(), close() and flush() methods
114 * @users: stores number of users (input handlers) that opened this
115 * device. It is used by input_open_device() and input_close_device()
116 * to make sure that dev->open() is only called when the first
117 * user opens device and dev->close() is called when the very
118 * last user closes the device
119 * @going_away: marks devices that are in a middle of unregistering and
120 * causes input_open_device() and input_inhibit/uninhibit_device()
121 * to fail with -ENODEV.
122 * @dev: driver model's view of this device
123 * @h_list: list of input handles associated with the device. When
124 * accessing the list dev->mutex must be held
125 * @node: used to place the device onto input_dev_list
126 * @num_vals: number of values queued in the current frame
127 * @max_vals: maximum number of values queued in a frame
128 * @vals: array of values queued in the current frame
129 * @devres_managed: indicates that devices is managed with devres framework
130 * and needs not be explicitly unregistered or freed.
131 * @timestamp: storage for a timestamp set by input_set_timestamp called
132 * by a driver
133 * @inhibited: indicates that the input device is inhibited. If that is
134 * the case then input core ignores any events generated by the device.
135 * Device's close() is called when it is being inhibited and its open()
136 * is called when it is being uninhibited.
137 * @ready: indicates that the device has been successfully opened and is
138 * prepared to process events (like LEDs or sounds) sent from the
139 * input core.

278 * @event: event handler. This method is being called by input core with
279 * interrupts disabled and dev->event_lock spinlock held and so

281 * @events: event sequence handler. This method is being called by
282 * input core with interrupts disabled and dev->event_lock
283 * spinlock held and so it may not sleep. The method must return
284 * number of events passed to it.
285 * @filter: similar to @event; separates normal event handlers from
286 * "filters".
287 * @match: called after comparing device's id with handler's id_table
288 * to perform fine-grained matching between device and handler
289 * @connect: called when attaching a handler to an input device
290 * @disconnect: disconnects a handler from input device
291 * @start: starts handler for given handle. This function is called by
292 * input core when device is open and ready to process events,
293 * and also when device is uninhibited or when a process that "grabbed"
294 * a device releases it
295 * @passive_observer: set to %true by drivers only interested in observing
296 * data stream from devices if there are other users present. Such
297 * drivers will not result in starting underlying hardware device
298 * when input_open_device() is called for their handles
299 * @legacy_minors: set to %true by drivers using legacy minor ranges
300 * @minor: beginning of range of 32 legacy minors for devices this driver
301 * can provide
302 * @name: name of the handler, to be shown in /proc/bus/input/handlers

304 * handle
305 * @h_list: list of input handles associated with the handler
306 * @node: for placing the driver onto input_handler_list
307 *
308 * Input handlers attach to input devices and create input handles. There
309 * are likely several handlers attached to any given input device at the
310 * same time. All of them will get their copy of input event generated by
311 * the device.
312 *
313 * The very same structure is used to implement input filters. Input core
314 * allows filters to run first and will not pass event to regular handlers
315 * if any of the filters indicate that the event should be filtered (by
316 * returning %true from their filter() method).
317 *
318 * Note that input core serializes calls to connect() and disconnect()
319 * methods.

547 * @playback: Called to request device to start playing specified effect
548 * @set_gain: Called to set specified gain
549 * @set_autocenter: Called to auto-center device
550 * @destroy: called by input core when parent input device is being
551 * destroyed
552 * @stop: called by input core when parent input device is being
553 * unregistered
554 * @private: driver-specific data, will be freed automatically
555 * @ffbit: bitmap of force feedback capabilities truly supported by
556 * device (not emulated like ones in input_dev->ffbit)
557 * @mutex: mutex for serializing access to the device
558 * @max_effects: maximum number of effects supported by device
559 * @effects: pointer to an array of effects currently loaded into device
560 * @effect_owners: array of effect owners; when file handle owning
561 * an effect gets closed the effect is automatically erased
562 *
563 * Every force-feedback device must implement upload() and playback()
564 * methods; erase() is optional. set_gain() and set_autocenter() need
565 * only be implemented if driver sets up FF_GAIN and FF_AUTOCENTER
566 * bits.
567 *
568 * Note that playback(), set_gain() and set_autocenter() are called with
569 * dev->event_lock spinlock held and interrupts off and thus may not
570 * sleep.
