- Optimizations for DMA map and unmap opertions through the type1
vfio IOMMU backend. This uses various means of batching and hints
from the mm structures to improve efficiency and therefore
performance, resulting in a significant speedup for huge page
use cases. (Li Zhe)
- Expose supported device migration features through debugfs.
