Right, for systems which don't need EDAC to decode to the DIMM or for
which there are no EDAC drivers written, they could use a tracepoint
which carries APEI info as-is. Others, which need EDAC, should probably
use trace_mc_event and disable the APEI tracepoint.
I think this should address Tony's concerns...
Btw, you could call your TP something simpler like
trace_ghes_memory_event or so.
Btw 2, if GHES can report other types of errors (I'm pretty sure it can)
maybe we can use a single tracepoint called trace_ghes_event for any
types of errors coming out of it...
Oh, and while at it, we probably need to start thinking of a mechanism
to disable all the error printing, i.e. cper_print_mem() and such,
if a userspace agent is listening in on the tracepoint and the error
information is carried through it to userspace.
Thanks.
