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! fumin ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
