Does anyone happen to know the usage of below member in
fb_var_screeninfo? I do not know whether mm stand for geometry size or
memory, can not find its usage in any driver neither. We considering
to use it as zoomed size.
struct fb_var_screeninfo {
__u32 height; /* height of picture in mm */
__u32 width; /* width of picture in mm */

They are both geometry sizes in millimeters.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
