Jumping on the wagon ;)
Can we enable CONFIG_DMAR please? This turns on the IOMMU on intel
boxes, using VT-d. Called "DMA Remapping" in intel speak, this is where
the config option name comes from. Advantages:
(1) 32bit PCI devices can DMA to memory above 4G, thus the need for
swiotlb (i.e. bounce buffers) is gone.
(2) It allows kvm to pass through PCI devices to guests securely.
thanks,
Gerd
