using OpenVG based on GC355 on imx6 Dual

I am using Yocto BSP for imx6 Dual and I have an example which uses OpenVG for rendering and i like to use libOpenVG_355.so. Now, I see that it is taking more CPU load around 100%.

I have a doubt and ran Tiger example which also i see that it is taking 50% cpu.

Based on documentation, i see that i can link libOpenVG.2d.so to libOpenVG.so  for using GPU GC355.so in imx6Dual.

We are using version 5.0.11.

But if i use OpenGL using GC2000 it is taking less CPU.

Is it that on imx6 Dual we dont use complete HW capabilities of GC355 or is there something i am missing.......

Hi 

You did not mention how are you taking those measurements however, there is a patch for graphics that includes a better performance for openvg according vgmark_gc355,  Graphics update to 5.0.11.p8.4 same as released in 3.14.52-1.1.1 patch release and is included in  4.1.15-1.2.0  meta-fsl-bsp-release bsp.

Please check if you are working with this version.
