Subject: Mirror "module" for framebuffer

Hi to all,

In short i should start to work to an application to remote control an 
android phone, just using the browser (video stream plus a lot of 
javascript).
While this is partially working right now, as you can imagine, phone is 
slow, a lot slow, so, while the framebuffer is little in most cases 
(320x256x2/320x256x4/800x480x2/800x480x4) a simple comparison, using 
neon extension too, if avaiable, is too slow, so the screen is refreshed 
too few times in a sec.

On windows exists Mirror Drivers infrastructure that supply a list of 
changed parts of the screen and more (mouse events too if i'm not 
wrong), but looking around on the web i didn't founded anything related 
to this stuff (or similar) for linux.

So, before i start scrambling docs and source code (i've really little 
experience with kernel module programming, i've done simply things), i 
want to ask a simple question: can be done using a sort of hooking of 
internal framebuffer function calls (fb_ops for example) or it's 
impossible because apps write directly into the framebuffer memory?

Thank you!!!


Best Regards,
Daniele
