- 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
