Subject: [PATCH v4 0/2] Add IntelVTdDmarPei Driver
Date: Wed, 6 Jan 2021 14:31:16 +0800 [thread overview]
Message-ID: <20210106063118.17216-1-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.
gIntelSiliconPkgTokenSpaceGuid.PcdVtdDmarPeiEnable is added for select
pre-boot DMA protection driver in PEI phase.
IntelVTdPmrPei driver is used to do the pre-boot DMA protection by PMR.
IntelVTdDmarPei driver is used to do the pre-boot DMA protection by DMAR.
