If the pixel in framebuffer memory isn't modified since we uploaded it, we can just read from the system memory copy, wihch avoids both a readback and an accelerator stall. In principle this function is still wrong, and all the framebuffer pixel access should be going through (w)fb so we can get pixel layout corrections. |
