Adding Mainline Arm Frame Buffer Compression Support for Rockchip

• mmastrac 7y ago
  From that sample buffer, it looks like this is just some sort of RLE? What happens in the "worst case" for compression? Does that just mean you can't hit your fps budget?

    It is as much or more about saving power by reducing costly traffic to the external RAM. For the pathological cases where you don't compress you simple don't save power, on average you do.

      Good point. I hadn't imagined that particular case.
