Component IOMMU_DEFAULT_DMA_STRICT

Component Type: kbuild config

Description: Translated - Strict

More info: Trusted devices use translation to restrict their access to only DMA-mapped pages, with strict TLB invalidation on unmap. Equivalent to passing "iommu.passthrough=0 iommu.strict=1" on the command line. Untrusted devices always use this mode, with an additional layer of bounce-buffering such that they cannot gain access to any unrelated data within a mapped page.

Build project: Kconfig (Linux kconfig) (Path: drivers\iommu\Kconfig )
