The SW_RADIO code for EV_SW events has a name that is not descriptive enough of its intended function, and could induce someone to think KEY_RADIO is its EV_KEY counterpart, which is false. Rename it to SW_RFKILL_ALL, and document what this event is for. Keep the old name around, to avoid userspace ABI breaks. The SW_RFKILL_ALL event is meant to be used by rfkill master switches. It is not bound to a particular radio switch type, and usually applies to all types. It is semantically tied to master rfkill switches that enable or disable every radio in a system.

/**
|
|
* struct input_dev - represents an input device
|
|
* @name: name of the device
|
|
* @phys: physical path to the device in the system hierarchy
|
|
* @uniq: unique identification code for the device (if device has it)
|
|
* @id: id of the device (struct input_id)
|
|
* @evbit: bitmap of types of events supported by the device (EV_KEY,
|
|
* EV_REL, etc.)
|
|
* @keybit: bitmap of keys/buttons this device has
|
|
* @relbit: bitmap of relative axes for the device
|
|
* @absbit: bitmap of absolute axes for the device
|
|
* @mscbit: bitmap of miscellaneous events supported by the device
|
|
* @ledbit: bitmap of leds present on the device
|
|
* @sndbit: bitmap of sound effects supported by the device
|
|
* @ffbit: bitmap of force feedback effects supported by the device
|
|
* @swbit: bitmap of switches present on the device
|
|
* @keycodemax: size of keycode table
|
|
* @keycodesize: size of elements in keycode table
|
|
* @keycode: map of scancodes to keycodes for this device
|
|
* @setkeycode: optional method to alter current keymap, used to implement
|
|
* sparse keymaps. If not supplied default mechanism will be used
|
|
* @getkeycode: optional method to retrieve current keymap. If not supplied
|
|
* default mechanism will be used
|
|
* @ff: force feedback structure associated with the device if device
|
|
* supports force feedback effects
|
|
* @repeat_key: stores key code of the last key pressed; used to implement
|
|
* software autorepeat
|
|
* @timer: timer for software autorepeat
|
|
* @sync: set to 1 when there were no new events since last EV_SYNC
|
|
* @abs: current values for reports from absolute axes
|
|
* @rep: current values for autorepeat parameters (delay, rate)
|
|
* @key: reflects current state of device's keys/buttons
|
|
* @led: reflects current state of device's LEDs
|
|
* @snd: reflects current state of sound effects
|
|
* @sw: reflects current state of device's switches
|
|
* @absmax: maximum values for events coming from absolute axes
|
|
* @absmin: minimum values for events coming from absolute axes
|
|
* @absfuzz: describes noisiness for axes
|
|
* @absflat: size of the center flat position (used by joydev)
|
|
* @open: this method is called when the very first user calls
|
|
* input_open_device(). The driver must prepare the device
|
|
* to start generating events (start polling thread,
|
|
* request an IRQ, submit URB, etc.)
|
|
* @close: this method is called when the very last user calls
|
|
* input_close_device().
|
|
* @flush: purges the device. Most commonly used to get rid of force
|
|
* feedback effects loaded into the device when disconnecting
|
|
* from it
|
|
* @event: event handler for events sent _to_ the device, like EV_LED
|
|
* or EV_SND. The device is expected to carry out the requested
|
|
* action (turn on a LED, play sound, etc.) The call is protected
|
|
* by @event_lock and must not sleep
|
|
* @grab: input handle that currently has the device grabbed (via
|
|
* EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
|
|
* recipient for all input events coming from the device
|
|
* @event_lock: this spinlock is is taken when input core receives
|
|
* and processes a new event for the device (in input_event()).
|
|
* Code that accesses and/or modifies parameters of a device
|
|
* (such as keymap or absmin, absmax, absfuzz, etc.) after device
|
|
* has been registered with input core must take this lock.
|
|
* @mutex: serializes calls to open(), close() and flush() methods
|
|
* @users: stores number of users (input handlers) that opened this
|
|
* device. It is used by input_open_device() and input_close_device()
|
|
* to make sure that dev->open() is only called when the first
|
|
* user opens device and dev->close() is called when the very
|
|
* last user closes the device
|
|
* @going_away: marks devices that are in a middle of unregistering and
|
|
* causes input_open_device*() fail with -ENODEV.
|
|
* @dev: driver model's view of this device
|
|
* @h_list: list of input handles associated with the device. When
|
|
* accessing the list dev->mutex must be held
|
|
* @node: used to place the device onto input_dev_list
|
