I have some idea about updating fbdev in advance.
Based on my current understanding, ipdf preloads the next page in background and writes image data to fbdev, so that when pagebar is flipped, the next page will be drawn from fbdev directly. That's why ipdf can update a page as fast as in 2 second.
When I used xepdmgr, I could get page refresh in as fast as 3 seconds when I prepared the next page in background. I guess the one second difference was due to not pre-writing to fbdev in advance.
Is it possible for xepdmgr (or xepdmgrclient) to provide a function for apps to control writing to fbdev in advance?
