int con_clear_unimap	(	struct vc_data *	vc,

int con_copy_unimap	(	struct vc_data *	dst_vc,
		struct vc_data *	src_vc
	)

con_copy_unimap - copy unimap between two vts : target : source

The caller must hold the console lock when invoking this method

		struct unipair __user *	list
	)

con_get_unimap - get the unicode map : the console to read from

Read the console unicode data for this console. Called from the ioctl handlers.

Definition at line 733 of file consolemap.c.

int con_set_default_unimap

(

struct vc_data *

vc

)

con_set_default_unimap - set default unicode map : the console we are updating

Loads the unimap for the hardware font, as defined in uni_hash.tbl. The representation used was the most compact I could come up with. This routine is executed at video setup, and when the PIO_FONTRESET ioctl is called.

The caller must hold the console lock
