Both have an MMU, but both are software managed.  That's one of the
functions that the hypervisor provides for us.

Congrats on getting the bootloader working.

Linas already answered some of your questions (thanks Linas!)

Hexagon Linux so far has been just used on internal projects; it's
not a part of any products even though the processor itself is.  A
non-hypervisor port is certainly possible, but for our purposes
around here, it's always running under the hypervisor.


Thanks,
