Dear all,
I am studying the Graphics stack in linux.
I found that the Intel Baytrail E38xx support 2 pipe display and each pipe
has
- 1 x primary plane
- 2 x sprite plane
- 1 x cursor plane

Is it possible to use sprite plane as overlay plane which means we can
render UI to sprite plane (for example QT could render Widget to sprite
plane) ? If so, could any one point me to some a sample code or any
documents ?

Many Thanks,
--
