Yes. We had lots of discussion about how to map memory errors over the last couple years. Basically, it was decided that the information that could be decoded into a DIMM to be mapped as integers, and all other driver-specific data to be added as strings. On the tests I did, different machines/vendors fill the APEI data on a different way, with makes harder to associate them to a DIMM. > Also, the fru id/text don't seem to be passed to user-space. That's likely because on the systems I tested, those fields were not filled (or maybe they appeared on a latter ACPI version). We should add them also the same string as the other fields there at ghes_edac.
