Subject: Regarding HMM

Hi All,
Im trying to understand heterogeneous memory management, i have
following doubts.
If HMM is being used we dont have to use DMA controller on device for
memory transfers ?
Without DMA if software is managing page faults and migrations, will
there be any performance impacts ?
Is HMM targeted for any specific use cases where DMA controller is not
there on device ?
Regards,
Valmiki
