I am worrying about having two sets of APIs for single purpose. From
vendor iommu driver's point of view, this feature is per device. Hence,
it still needs to do the same thing.
Yes, we can unify the granule of feature reporting and status management.
The basic granule of dirty tracking is iommu_domain, I think it's very
reasonable. We need an
interface to report the feature of iommu_domain, then the logic is much more
clear.
Every time we add new device or remove device from the domain, we should update
the feature (e.g.,
maintain a counter of unsupported devices).
Yes. This looks cleaner.
What do you think about this idea?
Thanks,
Keqian
