I have a display that is, e.g., 2560x1600 on an ivybridge. I'd like to set it up so that the software sees a display with half that resolution, i.e. the software that draws into the frame buffer (this is a bios) can draw into what it sees as a 1280x800 display. I've tried a few things but I'm realizing I don't understand the ivybridge panel fitter at all. This display is on PIPEA. It appears on sandybridge one can write PFA_VSCALE, PFA_HSCALE, PFA_WIN_SZ, and PFA_WIN_POS and _PFA_CTL_1 and it all works. On Ivybridge it seems far more complex. Or am I missing something? I don't see any fitting code in the drm driver itself, so I'm not quite sure how it's done. Thanks in advance, as always. ron
