Re: [rtl] rt display in usec

Hi,

- make a dga access to a X(gtk-canvas) in Xwindow apps
- give throught rt-fifo physical address to your rt-process
- remap the dga buffer in kernel space
- and use a real-time process to do image processing (including
formatting your picture in dga buffer).

Normally your dga-buffer is position independant ... but take care if
you iconify your Xapps !!!
