Missing libraries and poor performance on armv7hf target compared to armv6hf target

    Details

      Description

      I noticed there is a significant drop in performance when I switched to use armv7hf instead armv6hf target for my iMX 6 device. HelloFPS frame rate drops from ~400 fps to ~8 fps.
      Running verbose on armv7 showed the following library is missing:

      Prism pipeline init order: es2 sw
      Using platform text rasterizer
      Using native-based Pisces rasterizer
      Using dirty region optimizations
      Using system sized mask for primitives
      Not forcing power of 2 sizes for textures
      Using hardware CLAMP_TO_ZERO mode
      Opting in for HiDPI pixel scaling
      Prism pipeline name = com.sun.prism.es2.ES2Pipeline
      Loading ES2 native library ... prism_es2_monocle
      GraphicsPipeline.createPipeline failed for com.sun.prism.es2.ES2Pipeline
