I'm afraid I don't understand. We do cache all AMD nothbridges in arch/x86/kernel/amd_nb.c and use them to query different things about hw configuration. And we do that in different places already. So I'm proposing to use that already cached info to query the ECC status too. I don't see anything wrong with that and I don't see how that would repeat any iteration... -- Regards/Gruss, Boris.
