I was under the impression that unified memory concurrent access would be supported on Xavier since it is compute capability 7.2:

However, when I check the value of concurrentManagedAccess on Xavier using cudaGetDeviceProperties() it has value 0 and when I test concurrent access using test code, it fails. I’m using the latest JetPack 4.1.1.
Will unified memory concurrent access be enabled in a future JetPack for Xavier?
Thanks.
