I beg to differ. From the UEFI spec:

"The module number of the memory error location. (NODE, CARD, and MODULE
should provide the information necessary to identify the failing FRU)."

So this tuple is sufficient to pinpoint the DIMM, IIUC.

Which means, ghes_edac can have a single layer of DIMMs without channels.
