Lemme try again: you said that those errors do get reported through a
deferred interrupt. Which is likely amd_deferred_error_interrupt().
If it is that interrupt and you don't have CONFIG_X86_MCE_AMD enabled,
then you won't get any errors reported and your RAS functionality will
simply sit there inactive.
So if that above is true - something to which I'm still not getting
an answer but maybe one fine day... - so if that above is true, your
RAS functionality *needs* CONFIG_X86_MCE_AMD to be enabled in order to
*actually* function.
So you *must* make your RAS functionality depend on CONFIG_X86_MCE_AMD
- otherwise no deferred interrupts and no errors reported. It is that
simple.
