Create the modeline based on the full gtf algorithm
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);
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
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.
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.
