I can see some references for /dev/rga and /dev/rk29-ipp in some libraries.

Yes, you are right. We use hardware rga to composite to final framebuffer directly and ipp is for deinterlace.

thank you.

I lightly checked Rockchip's ICS source distributed from
it seems SurfaceFlinger::composeSurfaces() calls DisplayHardware::RenderVPUBuffToLayerBuff which uses rga on Rockchip device. then, all normal apps which use SurfaceFlinger to do composition can get benefit from hardware.

I guess other SoCs can behave similarly if it can do hardware composition. (it may be done by 3D accelerator, or it may be done by 2D accelerator)
