This patch is the start of my original work. The goal was: 1) One function for to draw at any color depth. 2) 16 color image data does need special padding. 3) Use fb_pixmap to control drawing to the hardware.I'm getting rejects with this patch. Did you benchmark this and compared the performance with the old one?Need to update patch to newest kernel. Not yet, there are still bugs to hammer away on.
I don't have to test the patch to see that it is not endian-correct and that it will be many times slower than the old code.
