Allocating Pixmap in Card Memory

[manisha salve]

Hi ,

I am writing  a DDX driver for 2D acceleration in Kdrive.  I am trying to
figure out for CopyArea acceleration how to get pixmaps allocated in an area
of memory that card can access .
According to my understanding , application creates Pixmap anywhere in the
system memory .But my graphics controller is not able to access that memory
area for the acceleration.

Please guide me to resolve this problem, How can i allocate pixmap in card
memory ????

Thanks
