2007-10-19Console keyboard events and accessibilitySamuel Thibault
Some blind people use a kernel engine called Speakup which uses hardware synthesis to speak what gets displayed on the screen. They use the PC keyboard to control this engine (start/stop, accelerate, ...) and also need to get keyboard feedback (to make sure to know what they are typing, the caps lock status, etc.) Up to now, the way it was done was very ugly. Below is a patch to add a notifier list for permitting a far better implementation, see ChangeLog above for details. You may wonder why this can't be done at the input layer. The problem is that what people want to monitor is the console keyboard, i.e. all input keyboards that got attached to the console, and with the currently active keymap (i.e. keysyms, not only keycodes). This adds a keyboard notifier that such modules can use to get the keyboard events and possibly eat them, at several stages: - keycodes: even before translation into keysym. - unbound keycodes: when no keysym is bound. - unicode: when the keycode would get translated into a unicode character. - keysym: when the keycode would get translated into a keysym. - post_keysym: after the keysym got interpreted, so as to see the result (caps lock, etc.) This also provides access to k_handler so as to permit simulation of keypresses.

2007-10-11Input: keyboard - add CapsShift lockSamuel Thibault
There exists a CapsShift lock called KG_CAPSSHIFT, but no associated lock/slock, here is a patch which adds CapsShift lock and slock. Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2006-04-02Input: add support for Braille devicesSamuel Thibault
- Add KEY_BRL_* input keys and K_BRL_* keycodes; - Add emulation of how braille keyboards usually combine braille dots to the console keyboard driver; - Add handling of unicode U+28xy diacritics.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
