Hi all,<br>        I have ported kdrive on arm.I want to accelerate the 2D operations of drawing lines,rectangles,filling rectangles,blit operations etc using a smart graphics accelerator for a SOC on which i am working . I have seen the sample drivers for neomagic and nvidia. They are not accelerating primitive drawing 
functions.Can these functions be accelerated?I think kdrive does not provide support for accelerating the primitive functions.It does it through software only because of overhead in these drawing primitives.<br>It only provides supoort for accelerating the ones in the following structure
