Something I also noticed is this:

                plane->state->crtc_y * plane->state->fb->pitches[0] +
                plane->state->crtc_x * bpp / 8;

Surely this should be using src_[xy] (which are the position in the
source - iow, memory, and not crtc_[xy] which is the position on the
CRTC displayed window.  To put it another way, the src_* define the
region of the source material that is mapped onto a rectangular area
on the display defined by crtc_*.

This problem still exists...
