(VFIO) is untrusted, ok. But a malicious driver loaded into the kernel
address space would have much easier ways to corrupt the system than to

Currently, many peripherals are faster than before. For example, the top
speed of the older netcard is 10Gb/s, and now it's more than 25Gb/s. But
when iommu page-table mapping enabled, it's hard to reach the top speed
in strict mode, because of frequently map and unmap operations. In order
to keep
