Do we have any other means of supporting this?
I guess the memory on the USB device cannot be mapped by the CPU and is not directly readable or writable. It would be most reasonable to implement a new system module with a special surface pool that implements transfer from and to the device. I wouldn't even think of writing a kernel frame buffer driver :) -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
