Is there any big difference between XEN SMMU driver and linux SMMU driver?
I know that XEN only support Stage 2. But the initliaization flow is almost the
same.
The SMMU driver for Xen is a port from Linux 3.19-rc0. Since then the Linux
driver has been reworked and it might be possible that we have missed some
bug fix.
Aside that, for Xen, the page tables are always shared between the SMMU and
the processor.
Thanks. I shared two picture that dumped using TRACE32.
