Hi,
here is a patch-set to make the AMD IOMMU driver use the
generic IOVA allocator, which is already used in the Intel
VT-d driver and a few other places.
The main reason for the conversion is to make the driver
benefit from the recent scalability improvements to the IOVA
code. Some of these improvements happened in the Intel VT-d
driver, these are not re-used but, for now, re-implemented.
This leaves more room for merging things together into
common code for the future.
The allocator that was previously used will be removed with
these patches.
Please review.
Thanks,
Joerg
