This is defined in section N.2.3 of UEFI version 2.5. Currently if the CPER section's type (UUID) does not match with any section type that the kernel knows how to parse, trace event is not generated for such section. And thus user is not able to know happening of such hardware error, including error record of non-standard section. This commit generates a trace event which contains raw error data for unrecognized CPER section.
