Currently, QEMU supports emulating either stage-1 or stage-2 SMMUs
but not nested instances.
This patch series adds support for nested translation in SMMUv3,
this is controlled by property “arm-smmuv3.stage=nested”, and
advertised to guests as (IDR0.S1P == 1 && IDR0.S2P == 2)
For the whole series (3-9, 11, 12, 15, 16, 18):

Jean-Philippe and I have followed up the progress of this series,
Mostafa took into account all our comments and all the patches were
reviewed. It seems to be in a pretty decent state so if you don't have
any objection, please consider pulling it for 9.1.
On my end I did some testing in non nesting mode with virtio-net/vhost
and I have not noticed any regression.
Would be nice if someone could send his T-b for the nested part though
(Julien?).
I haven't yet tried the latest version. I will do that in the next
couple of days.
Cheers,
