Unified memory allocator


This page gives a set of test pipelines to use cudafilter element for NVMM direct mapping mode. 

These examples will only run in JetPack 3.0 and below. For newer JetPack versions, please refer to https://developer.ridgerun.com/wiki/index.php?title=GstCUDA_-_Example_-_cudafilter:_Unified_memory_allocator

 The perf element can be downloaded from this repository. Otherwise, the element can be removed from the pipeline without any issues.
