Hi Marc,
I think I have fully tested this patch. The next step is to do some restriction
on
HVA in vfio module, so we can build block mapping for it with a higher
probability.
Is there anything to improve? If not, could you apply it? ^_^
Thanks,
Keqian

The MMIO region of a device maybe huge (GB level), try to use
block mapping in stage2 to speedup both map and unmap.
Compared to normal memory mapping, we should consider two more
points when try block mapping for MMIO region:
1. For normal memory mapping, the PA(host physical address) and
HVA ha
