SYNOPSIS

struct drm_display_mode * drm_gtf_mode_complex(struct drm_device * dev, int hdisplay, int vdisplay, int vrefresh, bool interlaced, int margins, int GTF_M, int GTF_2C, int GTF_K, int GTF_2J);

ARGUMENTS

dev

drm device

hdisplay

hdisplay size

vdisplay

vdisplay size

vrefresh

vrefresh rate.

interlaced

whether to compute an interlaced mode

margins

desired margin (borders) size

GTF_M

extended GTF formula parameters

GTF_2C

extended GTF formula parameters

GTF_K

extended GTF formula parameters

GTF_2J

extended GTF formula parameters

DESCRIPTION

GTF feature blocks specify C and J in multiples of 0.5, so we pass them in here multiplied by two. For a C of 40, pass in 80.

RETURNS

The modeline based on the full GTF algorithm stored in a drm_display_mode object. The display mode object is allocated with drm_mode_create. Returns NULL when no mode could be allocated.
