Date: Fri, 8 Jan 2021 10:49:16 +0800 [thread overview]
Message-ID: <20210108024918.25204-1-w.sheng@intel.com> (raw)
IntelVTdDmarPei Driver is used for DMA protection in PEI phase.
In pre-memory phase, All the DMA access is blocked.
In post memory phase, it will set some memory in iommu DMA remapping
tranlation table for DMA access, and only the memory allocated by
EdkiiIoMmuPpi has the DMA access. For rest of the memory, DMA access
will be blocked.
Add IntelVTdDmarPei to IntelSiliconPkg.
