I think this description could be clearer, how about: --- ghes_do_proc() has a catch-all for unknown or unhandled CPER formats (UEFI v2.10 Appendix N 2.3), extlog_print() does not. This gap was noticed by a RAS test that injected CXL protocol errors which were notified to extlog_print() via the IOMCA (I/O Machine Check Architecture) mechanism. Bring parity to the extlog_print() path by including a similar trace_non_standard_event(). --- > > Cc: Dan Williams <dan.j.williams@intel.com> > Signed-off-by: Fabio M.

Not specific to *this* patch, but it's annoying to try to find tracepoint implementations. I guess it's TRACE_EVENT(non_standard_event, ...) in include/ras/ras_event.h. This has the same prototype as log_non_standard_event(), so could extlog_print() be made a little bit more like ghes_do_proc() by using log_non_standard_event() instead of trace_non_standard_event() directly?

In extlog_print(), trace "Non-standard Section Body" reported by firmware to the OS via Common Platform Error Record (CPER) (UEFI v2.10 Appendix N 2.3) to add further debug information and so to make ELOG log consistently with ghes_do_proc() (GHES).
