Hi, all In /frameworks/base/libs/ui/EGLDisplaySurface.cpp function EGLDisplaySurface::swapBuffers will use FBIOPUT_VSCREENINFO to interact with FB driver to do page flip. Why not use FBIOPAN_DISPLAY? I think FBIOPAN_DISPLAY should be more efficient. FB driver only need to update base address, instead of check all parameter in VSCREENINFO.
