tty/vt/keyboard: define LED triggers for VT keyboard lock states

2015-06-16T21:59:46+00:00

In addition to defining triggers for VT LED states, let's define triggers for VT keyboard lock states, such as "kbd-shiftlock", "kbd-altgrlock", etc. This permits to fix #7063 from userland by using a modifier to implement proper CapsLock behavior and have the keyboard caps lock led show that modifier state.

tty/vt/keyboard: define LED triggers for VT LED states

2015-06-16T21:59:46+00:00

Now that input core allows controlling keyboards LEDs via standard LED subsystem triggers let's switch VT keyboard code to make use of this feature. We will define the following standard triggers: "kbd-scrollock", "kbd-numlock", "kbd-capslock", and "kbd-kanalock" which are default triggers for respective LEDs on keyboards.

tty: pr_warning->pr_warn and logging neatening

2014-11-26T01:06:38+00:00

Convert the pr_warning to the more common pr_warn. Other miscellanea: o Convert unusual PR_FMT define and uses to pr_fmt o Remove unnecessary OOM message o Fix grammar in an error message o Convert a pr_warning with a KERN_ERR to pr_err Signed-off-by: Joe Perches Signed-off-by: Greg Kroah-Hartman

tty/vt/keyboard: Resolve many shadow warnings

2014-09-08T23:30:43+00:00

Many local variables were given the same name as a global. This is valid, but generates many shadow warnings in W=2 builds. Resolve them by changing the local names. Also change local variables named "up" because they shadow the semaphore "up" function. Also moved the outer declaration of the variable "a" because it is only used in one block, and that resolves all of the shadow warnings for the other declarations of "a" that have different types. Change diacr => dia, kbd => kb, rep => rpt, up => udp. Signed-off-by: Mark Rustad Signed-off-by: Jeff Kirsher Signed-off-by: Greg Kroah-Hartman

tty: Remove dead code

2013-07-26T23:19:48+00:00

-> The ledptrs[] array is never initialized. -> There is no place where kbd->ledmode is set to LED_SHOW_MEM therefore the if statement does not make much sense. -> Since LED_SHOW_MEM is not used, it can be removed from the header file as well.

TTY: switch tty_schedule_flip

2013-01-16T06:43:15+00:00

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. This is the last one: tty_schedule_flip Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

TTY: switch tty_insert_flip_char

2013-01-16T06:21:36+00:00

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. tty_insert_flip_char is the next one to proceed. This one is used all over the code, so the patch is huge.

vt: fix the keyboard/led locking

2012-07-17T16:13:37+00:00

We touch the LED from both keyboard callback and direct paths. In one case we've got the lock held way up the call chain and in the other we haven't. This leads to complete insanity so fix it by giving the LED bits their own lock. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

tty: keyboard.c: Remove locking from vt_get_leds.

2012-07-06T21:28:17+00:00

There are three call sites for this function, and all three are called within a keyboard handler. kbd_event_lock is already held within keyboard handlers, so attempting to lock it in vt_get_leds causes deadlock.

TTY: vt, remove con_schedule_flip

2012-06-14T00:30:53+00:00

This is identical to tty_schedule_flip. So let us use that instead. Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman
