[PATCH v3 0/5] Parse SMBIOS additional entries

From: Mario Limonciello (AMD)

Date: Sat Jan 10 2026 - 08:48:45 EST


The SMBIOS additional entries on AMD Zen4+ systems running an AGESA
based BIOS contain information about the AGESA version which can be
useful for matching the software stack when debugging an issue.

Add support for parsing this from SMBIOS tables and output it into
the logs at bootup. Additionally export the information to debugfs
in case users are interested in any other strings.

v3:
* Drop / merge patches from feedback
* Don't save additional strings, only show AGESA string if found
