Subject: Regarding HMM
Date: Tue, 18 Aug 2020 12:45:06 +0530	[thread overview]
Message-ID: <b2c02ebc-8313-e7f2-7bde-2141f7969da2@gmail.com> (raw)

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
