Subject: [PATCH 0/5] Parse SMBIOS additional entries
Date: Sun, 14 Dec 2025 12:53:04 -0600 [thread overview]
Message-ID: <20251214185309.152614-1-superm1@kernel.org> (raw)
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.
Mario Limonciello (AMD) (5):
firmware: dmi: Correct an indexing error in dmi.h
firmware: dmi: Adjust dmi_decode() to use enums
firmware: dmi: Read additional information when decoding DMI table
firmware: dmi: Add debugfs for additional information entries
x86/amd_node: Output the AGESA version to the logs
