| * Input: add KEY_IMAGES specifically for AL Image BrowserJarod Wilson2011-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many media center remotes have buttons intended for jumping straight to one type of media browser or another -- commonly, images/photos/pictures, audio/music, television, and movies. At present, remotes with an images or photos or pictures button use any number of different keycodes which sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA, KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right. In my mind, KEY_MEDIA should be something more like a media center application launcher (and I'd like to standardize on that for things like the windows media center button on the mce remotes). KEY_CAMERA is used in a lot of webcams, and typically means "take a picture now". KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION might be the closest fit here, if you think "photo slide show", but it may well be more intended for "run application in full-screen presentation mode" or to launch something like magicpoint, I dunno. And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL Image Browser, the meaning of which I think is crystal-clear. I believe AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser by KEY_VIDEO, so I'm also adding appropriate comments next to those keys.

This is not always enough; a tablet and a touchscreen may emit exactly the same data, for instance, but the former should be set up with a pointer whereas the latter does not need to. Recently, a new type of touchpad has emerged where the buttons are under the pad, which changes logic without changing the emitted data. This patch introduces a new ioctl, EVIOCGPROP, which enables user access to a set of device properties useful during setup. The properties are given as a bitmap in the same fashion as the event types, and are also made available via sysfs, uevent and /proc/bus/input/devices.

The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver.

While we tried to keep ABI intact (and we succeeded in doing that, programs compiled on older kernels will work on newer ones) there is still a problem with recompiling existing software with newer kernel headers. New kernel headers will supply updated ioctl numbers and kernel will expect that userspace will use struct input_keymap_entry to set and retrieve keymap data. But since the names of ioctls are still the same userspace will happily compile even if not adjusted to make use of the new structure and will start miraculously fail in the field. To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly select the style of ioctls it wants to employ.

| * Input: add support for large scancodesMauro Carvalho Chehab2010-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices use a high number of bits for scancodes. One important group is the Remote Controllers. Some new protocols like RC-6 define a scancode space of 64 bits. The current EVIO[CS]GKEYCODE ioctls allow replace the scancode/keycode translation tables, but it is limited to up to 32 bits for scancode. Also, if userspace wants to clean the existing table, replacing it by a new one, it needs to run a loop calling the ioctls over the entire sparse scancode space. To solve those problems, this patch extends the ioctls to allow drivers handle scancodes up to 32 bytes long (the length could be extended in the future should such need arise) and allow userspace to query and set scancode to keycode mappings not only by scancode but also by index. Compatibility code were also added to handle the old format of EVIO[CS]GKEYCODE ioctls. Folded fixes by: - Dan Carpenter: locking fixes for the original implementation - Jarod Wilson: fix crash when setting keycode and wiring up get/set handlers in original implementation. - Dmitry Torokhov: rework to consolidate old and new scancode handling, provide options to act either by index or scancode.

* Input: introduce MT event slotsHenrik Rydberg2010-07-16
| | | | | | | | | | | | | | | | | | | | | With the rapidly increasing number of intelligent multi-contact and multi-user devices, the need to send digested, filtered information from a set of different sources within the same device is imminent. This patch adds the concept of slots to the MT protocol. The slots enumerate a set of identified sources, such that all MT events can be passed independently and selectively per identified source. The protocol works like this: Instead of sending a SYN_MT_REPORT event immediately after the contact data, one sends an ABS_MT_SLOT event immediately before the contact data. The input core will only emit events for slots with modified MT events. It is assumed that the same slot is used for the duration of an initiated contact.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes it is desirable to suppress certain events from reaching input handlers and thus user space. One such example is Mac mouse button emulation code which catches certain key presses and converts them into button clicks as if they were emitted by a virtual mouse. The original key press events should be completely suppressed, otherwise user space will be confused, and while keyboard driver does it on its own evdev is blissfully unaware of this arrangement. This patch adds notion of 'filter' to the standard input handlers, which may flag event as filtered thus preventing it from reaching other input handlers. Filters don't (nor will they ever) have a notion of priority relative to each other, input core will run all of them first and any one of them may mark event as filtered. This patch is inspired by similar patch by Matthew Garret but the implementation and intended usage are quite different. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| * | | HID: handle joysticks with large number of buttonsJiri Kosina2010-01-04
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current HID code doesn't properly handle HID joysticks which have larger number of buttons than what fits into current range reserved for BTN_JOYSTICK. One such joystick reported to not work properly is Saitek X52 Pro Flight System. We can't extend the range to fit more buttons in, because of backwards compatibility reasons. Therefore this patch introduces a new BTN_TRIGGER_HAPPY range, and uses these to map the buttons which are over BTN_JOYSTICK limit.

* | | Input: add KEY_RFKILLMatthew Garrett2010-02-18
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | Most laptops have keys that are intended to toggle all device state, not just wifi. These are currently generally mapped to KEY_WLAN. As a result, rfkill will only kill or enable wifi in response to the key press. This confuses users and can make it difficult for them to enable bluetooth and wwan devices. This patch adds a new keycode, KEY_RFKILL. It indicates that the system should toggle the state of all rfkillable devices.

|/ | | | | | | | | | | | For pressure-based multi-touch devices, a direct way to send sensor intensity data per finger is needed. This patch adds the ABS_MT_PRESSURE event to the MT protocol.

| * Input: fix locking in memoryless force-feedback devicesDmitry Torokhov2009-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that input core acquires dev->event_lock spinlock and disables interrupts when propagating input events, using spin_lock_bh() in ff-memless driver is not allowed. Actually, the timer_lock itself is not needed anymore, we should simply use dev->event_lock as well. Also do a small cleanup in force-feedback core.

* | Input: keyboard - fix lack of locking when traversing handler->h_listDmitry Torokhov2009-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | Keyboard handler should not attempt to traverse handler->h_list on its own, without any locking, otherwise it races with registering and unregistering of input handles which leads to crashes. Introduce input_handler_for_each_handle() helper that allows safely iterate over all handles attached to a particular handler and switch keyboard handler to use it.
