NAME
drm_rect_calc_vscale_relaxed - calculate the vertical scaling factor
SYNOPSIS
int drm_rect_calc_vscale_relaxed(struct drm_rect * src,
struct drm_rect * dst, int min_vscale,
int max_vscale);
ARGUMENTS
src
source window rectangle
dst
destination window rectangle
min_vscale
minimum allowed vertical scaling factor
max_vscale
maximum allowed vertical scaling factor
DESCRIPTION
Calculate the vertical scaling factor as (src height) / (dst height).
If the calculated scaling factor is below min_vscale, decrease the
height of rectangle dst to compensate.
If the calculated scaling factor is above max_vscale, decrease the
height of rectangle src to compensate.
RETURNS
The vertical scaling factor.
