2013-07-31printk: move braille console support into separate braille.[ch] filesJoe Perches
Create files with prototypes and static inlines for braille support. Make braille_console functions return 1 on success. Corrected CONFIG_A11Y_BRAILLE_CONSOLE=n _braille_console_setup return value to NULL.

2012-03-08vt:tackle kbd_tableAlan Cox
Keyboard struct lifetime is easy, but the locking is not and is completely ignored by the existing code. Tackle this one head on - Make the kbd_table private so we can run down all direct users - Hoick the relevant ioctl handlers into the keyboard layer - Lock them with the keyboard lock so they don't change mid keypress - Add helpers for things like console stop/start so we isolate the poking around properly - Tweak the braille console so it still builds There are a couple of FIXME locking cases left for ioctls that are so hideous they should be addressed in a later patch. After this patch the kbd_table is private and all the keyboard jiggery pokery is in one place. This update fixes speakup and also a memory leak in the original.

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-12-12drop explicit include of autoconf.hSam Ravnborg
kbuild.h forces include of autoconf.h on the commandline using -include - so we do not need to include the file explicit. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
2008-10-02braille_console: only register notifiers when the braille console is usedPascal Terjan
Only register the braille driver VT and keyboard notifiers when the braille console is used. Avoids eating insert or backspace keys.

2008-04-30Basic braille screen reader supportSamuel Thibault
This adds a minimalistic braille screen reader support. This is meant to be used by blind people e.g. on boot failures or when / cannot be mounted etc and thus the userland screen readers can not work.
