NAME

fb_find_mode - finds a valid video mode

SYNOPSIS

int __init fb_find_mode (struct fb_var_screeninfo *var, struct fb_info *info, const char *mode_option, const struct fb_videomode *db, unsigned int dbsize, const struct fb_videomode *default_mode, unsigned int default_bpp);

ARGUMENTS

var: frame buffer user defined part of display
info: frame buffer info structure
mode_option: string video mode to find
db: video mode database
dbsize: size of db
default_mode: default video mode to fall back to
default_bpp: default color depth in bits per pixel

DESCRIPTION

Finds a suitable video mode, starting with the specified mode in mode_option with fallback to default_mode. If default_mode fails, all modes in the video mode database will be tried.

Valid mode specifiers for mode_option:

<xres>x<yres>[-<bpp>][@<refresh>] or <name>[-<bpp>][@<refresh>]

with <xres>, <yres>, <bpp> and <refresh> decimal numbers and <name> a string.

NOTE

The passed struct var is _not_ cleared! This allows you to supply values for e.g. the grayscale and accel_flags fields.

Returns zero for failure, 1 if using specified mode_option, 2 if using specified mode_option with an ignored refresh rate, 3 if default mode is used, 4 if fall back to any valid mode.
