I have KCF tracker code whcih heavily relies on CPU rather than GPU, but I I would like to test its performance on Xavier.
When building OpenCV 3.4.6, I try turn on the NEON & VFPV3 flags
But CMAKE fails on VFPV3. The NEON flags by itself passes CMAKE.
Other guides (e.g. https://github.com/jetsonhacks/buildOpenCVXavier/blob/master/buildOpenCV.sh) do not include these flags when building OpenCV.
Per the public info, Carmel is a ARMv8.2 comliant vs the A53 which is ARMv8.0. I did find some guidance for the ARM A53 case that VFPV3 is supported:
Is VFPV3 supported on Carmel architecture.
