int vc_resize	(	struct vc_data *	vc,
		unsigned int	cols,
		unsigned int	rows
	)

vc_resize - resize a VT : virtual console : columns : rows

Resize a virtual console as seen from the console end of things. We use the common vc_do_resize methods to update the structures. The caller must hold the console sem to protect console internals and vc->port.tty

	)

vt_clr_kbd_mode_bit - read keyboard status bits : console to read from : mode bit to read

Report back a vt mode bit. We do this without locking so the caller must be sure that there are no synchronization needs

Definition at line 2189 of file keyboard.c.

int vt_do_diacrit	(	unsigned int	cmd,
		void __user *	up,
		int	perm

vt_do_diacrit - diacritical table updates : ioctl request : pointer to user data for ioctl : permissions check computed by caller

Update the diacritical tables atomically and safely. Lock them against simultaneous keypresses

vt_do_kdgkbmeta - report meta status : console to report

Report the meta flag status of this console

int vt_do_kdskbmeta	(	int	console,
		unsigned int	arg
	)

vt_do_kdskbmeta - set keyboard meta state : the console to use

: the requested meta state

Update the keyboard meta bits while holding the correct locks. Return 0 for success or an error code.

Definition at line 1752 of file keyboard.c.

int vt_do_kdskbmode	(	int	console,
		unsigned int	arg
	)

vt_do_kdskbmode - set keyboard mode ioctl : the console to use

: the requested mode

Update the keyboard mode bits while holding the correct locks. Return 0 for success or an error code.

vt_event_post : the event that occurred : old console : new console

Post an VT event to interested VT handlers

int vt_get_kbd_mode_bit	(	int	console,
		int	bit
	)

vt_get_kbd_mode_bit - read keyboard status bits : console to read from : mode bit to read

Report back a vt mode bit. We do this without locking so the caller must be sure that there are no synchronization needs

Definition at line 2155 of file keyboard.c.

int vt_get_leds	(	int	console,
		int	flag
	)

vt_get_leds - helper for braille console : console to read : flag we want to check

Check the status of a keyboard led flag and report it back

Definition at line 1051 of file keyboard.c.

int vt_get_shift_state ( void )

vt_get_shiftstate - shift bit state

Report the shift bits from the keyboard state. We have to export this to support some oddities in the vt layer.

Definition at line 2112 of file keyboard.c.

void vt_kbd_con_start ( int console )

vt_kbd_con_start - Keyboard side of console start : console

Handle console start. This is a wrapper for the VT layer so that we can keep kbd knowledge internal

FIXME: We eventually need to hold the kbd lock here to protect the LED updating. We can't do it yet because fn_hold calls stop_tty and start_tty under the kbd_event_lock, while normal tty paths don't hold the lock. We probably need to split out an LED lock but not during an -rc release!

Definition at line 1092 of file keyboard.c.

void vt_kbd_con_stop ( int console )

vt_kbd_con_stop - Keyboard side of console stop : console

Handle console stop. This is a wrapper for the VT layer so that we can keep kbd knowledge internal

void vt_reset_keyboard ( int console )

vt_reset_keyboard - reset keyboard state : console to reset

Reset the keyboard bits for a console as part of a general console reset event

Definition at line 2125 of file keyboard.c.

void vt_reset_unicode ( int console )

vt_reset_unicode - reset the unicode status : console being reset

Restore the unicode console state to its default

Definition at line 2097 of file keyboard.c.

void vt_set_kbd_mode_bit	(	int	console,
		int	bit
	)

vt_set_kbd_mode_bit - read keyboard status bits : console to read from : mode bit to read

Set a vt mode bit. We do this without locking so the caller must be sure that there are no synchronization needs

void vt_set_led_state	(	int	console,
		int	leds
	)

vt_set_led_state - set LED state of a console : console to set : LED bits

Set the LEDs on a console. This is a wrapper for the VT layer so that we can keep kbd knowledge internal

Definition at line 1073 of file keyboard.c.

int vt_waitactive ( int n )

vt_waitactive - active console wait : event code
: new console

Helper for event waits. Used to implement the legacy event waiting ioctls in terms of events
