I am wondering whether multiple frame-buffers for the same display is supported in Snapdragon processor. For example, Freescale/NXP i.MX6 series processors supports two frame-buffers for one display. We have applications written to use both frame-buffers. One frame-buffer /dev/fb0 used for QT UI and other frame-buffer /dev/fb1 used for native OpenGL waveform rendering. Alpha blending was enabled in the IPU such that blended output is rendered in the same LCD panel.
How can be achieve similar functionality in Dragonboard 410C. Does snapdragon chip supports multiple frame-buffers if so is it enabled in kernel.
