Hi Bin,
the ISP in Medfield has it's own MMU. This needs to be programmed.
So in fact we have 2 problems:
1. how to allocate large memory address space (allocating pages is not
the problem).
2. if we re-use OS functionality for this, we need to keep the ISP MMU
up to date.
This means it needs to

Hi Laurent,
You make this very clear, thank you!
The ISP on Medfield do have its own IOMMU. And I also think an IOMMU layer for
ISP is needed.
I'm not quite understand "unless hardware design doesn't give you a choice
about that,". Can you explain more on that?
Also regarding to the VCMM (Vir
