* vt: lock the accent tableAlan Cox2012-02-241-78/+3
| | | | | | | | | | | | First step to debletcherising the vt console layer - pick a victim and fix the locking This is a nice simple object with its own rules so lets pick it out for treatment. The user of the table already has a lock so we will also use the same lock for updates. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* drivers/tty/vt/vt_ioctl.c: fix KDFONTOP 32bit compatibility layerSamuel Thibault2012-02-031-1/+0
| | | | | | | | | | | | | | | | | | | | | KDFONTOP(GET) currently fails with EIO when being run in a 32bit userland with a 64bit kernel if the font width is not 8. This is because of the setting of the KD_FONT_FLAG_OLD flag, which makes con_font_get return EIO in such case. This flag should *not* be set for KDFONTOP, since it's actually the whole point of this flag (see comment in con_font_set for instance).

* | tty: now phase out the ioctl file pointer for goodAlan Cox2011-02-171-3/+3

* | tty,vt: fix VT_SETACTIVATE console switchJiri Olsa2011-02-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | using VT_SETACTIVATE ioctl for console switch did not work, since it put wrong param to the set_console function. Also ioctl returned misleading error, because of the missing break statement. I wonder anyone has ever used this one :).

* | vt: Add virtual console keyboard mode OFFArthur Taylor2011-02-171-0/+3
|/ | | | | | | | | | | | virtual console: add keyboard mode OFF Add a new mode for the virtual console keyboard OFF in which all input other than shift keys is ignored. Prevents vt input buffers from overflowing when a program opens but doesn't read from a tty, like X11 using evdev for input.

* console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn2011-01-261-30/+30
| | | | | | | | | | | | | | | | | | | | | | | | | The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.
