hello riwilliams,

am not quite understand your request,
there’s $ pmap commands you might use to show the memory usage of a process.
please also check the processes PID by $ ps aux .

you might refer to Xavier TRM, please refer to chapter-3.4 System Memory Management Unit (SMMU);
please also check the wiki page about memory protection for more details.
thanks
