Subject: [PATCH 1/6 v7] ACPI: extlog: Trace CPER Non-standard Section Body
Date: Tue,  4 Nov 2025 19:22:32 +0100	[thread overview]
Message-ID: <20251104182446.863422-2-fabio.m.de.francesco@linux.intel.com> (raw)
In-Reply-To: <20251104182446.863422-1-fabio.m.de.francesco@linux.intel.com>

ghes_do_proc() has a catch-all for unknown or unhandled CPER formats
(UEFI v2.11 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 log_non_standard_event().
