about Graphic Engine support

Hi,

    This is my first work on framebuffer.

    Now I have a 2D graphic Engine. I want to use it to speedup drawing 2D graph
by inputing data to the framebuffer's physical address directly.

    I have exported the __pa(registered_fb[0]->pixmap.addr) to my custom /proc/fbphy,
and put the physical address to the graphic engine as a destination address. Is it right?
When I do so, the kernel will core dump. So I guess the idea of mine maybe wrong....

Anyway,thanks for your response first!
