While analyzing the code of i915 driver I found that the graphic functions like 'blit' and 'fillrect' are mapped to functions like 'cfb_imageblit', 'cfb_fillrect'. Looking into 'cfb_xxxx' implementation, I understood that ultimately all of them puts image data(bit map) to a memory address. According to my expectation, this address should correspond to the video memory/graphics memory of the graphics hardware(So that it could be argued that hardware acceleration is used for the above mentioned functions). But it was observed that, the memory was kmalloc()'ed with FLAGS GFP_KERNEL. From the observation, can I conclude that the 'blit'/'fillrect' functions of i915 driver doesn't use hardware acceleration at all? Could anybody suggest me any other i915 functions for accessing 'blit'/'fillrect' functionalities with hardware acceleration? Please correct me wherever I am wrong.  <div dir="ltr"> <div>Thanks, Neeraj N.T </div> </div> <div dir="ltr"> <div> </div> </div>  </body> </html>
