Oh, dang, the ioctl() for updating the eink screen is taken 1:1 from the K3 -- probably it's a bit different on the K5. However, the K4 seems to take it quite well. But that's along the lines of what you posted earlier, geekmaster: K4 in "normal" mode is very much the K3's eink driver. Is there a region-based update for the K5? I'd rather not call eips, there would likely be something like on the K3, even an ioctl() perhaps?
