The following library classes are not used by this module, so remove them from the INF file's [LibraryClasses] section: - DxeServicesTableLib - UefiLib The following library classes are used by this module, so add them to the INF file's [LibraryClasses] section: - BaseMemoryLib (e.g. via CopyMem()) - MemoryAllocationLib (e.g. via AllocatePool()) Sort the list of library classes (in both "IoMmuDxe.inf" and "AmdSevIoMmu.h"). Remove all non-local #include directives from "IoMmuDxe.c"; both C files of this module include "AmdSevIoMmu.h", and "AmdSevIoMmu.h" includes all non-local headers already.

The protocol provides support to allocate, free, map and umap a DMA buffer
|
|
for bus master (e.g PciHostBridge). When SEV is enabled, the DMA operations
|
|
must be performed on unencrypted buffer hence protocol clear the encryption
|
|
bit from the DMA buffer.
