Input: define separate EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2

2010-12-15T07:55:21Z

The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while extending them to support large scancodes was a mistake. 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: document struct input_absinfo

Add documentation for struct input_absinfo that is used in EVIOCGABS and EVIOCSABS ioctl and specify units of measure used for reporting resolution for an axis. Acked-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

Input: add keycodes for touchpad on/off keys

2010-12-01T07:11:26Z

Some laptops will have a "touchpad toggle" soft button, which expects user-space to turn off the touchpad themselves, some other devices will do this in hardware, but send key events telling us that the touchpad has been turned off/on. KEY_TOUCHPAD_ON/KEY_TOUCHPAD_OFF will be used by user-space to show a popup with the status of the touchpad. Signed-off-by: Bastien Nocera Signed-off-by: Dmitry Torokhov

Input: export input_reset_device() for use in KGDB

2010-11-03T18:04:46Z

KGDB, much like the resume process, needs to be able to mark all keys that were pressed at the time we dropped into the debuggers as "released", since it is unlikely that the keys stay pressed for the entire duration of the debug session. Also we need to make sure that input_reset_device() and input_dev_suspend() only attempt to change state of currenlt opened devices since closed devices may not be ready to accept IO requests.

Input: add support for large scancodes

2010-09-10T05:00:50Z

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: dynamically allocate ABS information

2010-08-03T03:30:04Z

As all callers are now changed to only use the input_abs_*() access helpers, switching over to dynamically allocated ABS information is easy. This reduces size of struct input_dev from 3152 to 1640 on 64 bit architectures. Signed-off-by: Daniel Mack Signed-off-by: Dmitry Torokhov
