If the IOMMU is not able to snoop the cache, then the way forward is
to use a clean_dcache operation after writing a page table entry.
This is how we deal in the p2m code.
Agree.
As we update page table in an atomic way (no BBM sequence) and the
reason caused page faults was found, I think that the IPMMU driver can
declare superpage capability?
Yes for the IPMMU driver. Although we would have to do some things for
the SMMU driver.
Cheers,
