Subject: [PATCH 1/6 v5] ACPI: extlog: Trace CPER Non-standard Section Body
Date: Fri, 17 Oct 2025 15:30:46 +0200 [thread overview]
Message-ID: <20251017133357.1150982-2-fabio.m.de.francesco@linux.intel.com> (raw)
In-Reply-To: <20251017133357.1150982-1-fabio.m.de.francesco@linux.intel.com>
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 log_non_standard_event().
