Address translation

===================



x86 AMD

-------



Zen-based AMD systems include a Data Fabric that manages the layout of

physical memory. Devices attached to the Fabric, like memory controllers,

I/O, etc., may not have a complete view of the system physical memory map.

These devices may provide a "normalized", i.e. device physical, address

when reporting memory errors. Normalized addresses must be translated to

a system physical address for the kernel to action on the memory.



AMD Address Translation Library (CONFIG_AMD_ATL) provides translation for

this case.



Glossary of acronyms used in address translation for Zen-based systems



* CCM               = Cache Coherent Moderator

* COD               = Cluster-on-Die

* COH_ST            = Coherent Station

* DF                = Data Fabric
