Name

drm_gtf_mode_complex — create the modeline based on the full GTF algorithm

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.
