What's the different between gpu-viv-bin-mx6q-hfp and gpu-viv-bin-mx6q-sfp‏

raybloodworth · ‎09-22-2014

Hi,

There are "hfp" and "sfp" libs in gpu-viv-bin-mx6q-3.10.17-1.0.0.

Could anyone tell me what's the different between hfp andg sfp?

For board mcimx6q-sdb,which libs should I use?

I build "core-image-weston" with yocto imx-3.10.31-1.1.0_beta.It was hf by default.

Could anyone tell me how to build the sf version?

Hi lingxin

sfp - software floating point, hfp - hardware floating point.

I.MX6 cortex a9 has hardware floating point support (neon)

so software image may be generated with or without hardware floating point support.

Please look below for details

Regarding building details I believe most accurate answer you

can receive on meta-fsl-arm mailing list

Best regards

igor

Thanks for your reply!

I got this from mailing list.

Restart a clean build and add the followed line into your local.conf:

DEFAULTTUNE_mx6 = "cortexa9-neon"

BTW, if I use the gpu-viv-bin-mx6q-hfp, should I use "arm-linux-gnueabihf-gcc" to compile program ?
