Current Graphics drivers tend to use physical address
|
|
for DMA and avoid using DMA APIs. Setting this config
|
|
option permits the IOMMU driver to set a unity map for
|
|
all the OS-visible memory. Hence the driver can continue
|

to use physical addresses for DMA, at least until this

option is removed in the 2.6.32 kernel.

Floppy disk drivers are known to bypass DMA API calls

|
|
/sys/devices/virtual/iommu/dmar*/intel-iommu/ecap. If this option
