St
So that would be the driver code running in guest OS because i see
tables being setup by arm-smmu driver code in linux,which is similar to
what happens with ITS(table base addresses programmed in registers by
linux driver).

In that case, the stage 2 tables are set up by the guest
code (running at emulated EL2), just as they would be if
it were running on real
I am referring to the latter,"purely emulated QEMU with an emulated
SMMU that handles accesses to emulated devices"
Thanks

Hi All,
I am trying to understand the approach required for an emulated SMMU to
convert IPAs(from each qemu guest) to PAs(respective host addresses)
using stage 2 tables.
The questions i have are:-
1) Since SMMU stage 2 tables are expected to be created and managed by
a hypervisor,if there is no
