is included in a many files: $ git grep '' ef0c9f75a195 | wc -l 1598 ; some of them are widely used headers. To stop mixing up different and unrelated driver( type)s let the subsystem headers only use the subset of the recently split that are relevant for them. The fallout (I hope) is addressed in the previous commits that handle sources relying on e.g. pulling in the full legacy header and thus providing pci_device_id.

x86/CPU/AMD: Print AGESA string from DMI additional information entry

2026-04-01T18:54:16+00:00

Type 40 entries (Additional Information) are summarized in section 7.41 as part of the SMBIOS specification. Generally, these entries aren't interesting to save. However on some AMD Zen systems, the AGESA version is stored here. This is useful to save to the kernel message logs for debugging. It can be used to cross-reference issues. Implement an iterator for the Additional Information entries. Use this to find and print the AGESA string. Do so in AMD code, since the use case is AMD-specific.

firmware: dmi: Correct an indexing error in dmi.h

2026-04-01T18:53:44+00:00

The entries later in enum dmi_entry_type don't match the SMBIOS specification¹. The entry for type 33: `64-Bit Memory Error Information` is not present and thus the index for all later entries is incorrect. Add it. Also, add missing entry types 43-46, while at it. ¹ Search for "System Management BIOS (SMBIOS) Reference Specification" [ bp: Drop the flaky SMBIOS spec URL. ] Fixes: 93c890dbe5287 ("firmware: Add DMI entry types to the headers") Signed-off-by: Mario Limonciello (AMD) Signed-off-by: Borislav Petkov (AMD) Reviewed-by: Jean Delvare Reviewed-by: Yazen Ghannam Link: https://patch.msgid.link/20260307141024.819807-2-superm1@kernel.org

efi: Unify DMI setup code over the arm/arm64, ia64 and x86 architectures

2019-03-29T06:35:00+00:00

All architectures (arm/arm64, ia64 and x86) do the same here, so unify the code. Note: We do not need to call dump_stack_set_arch_desc() in case of !dmi_available. Both strings, dmi_ids_string and dump_stack_arch_ desc_str are initialized zero and thus nothing would change.

firmware/dmi_scan: Uninline dmi_get_bios_year() helper

2018-03-27T09:33:15+00:00

Uninline dmi_get_bios_year() which, in particular, allows us to optimize it in the future. While doing this, convert the function to return an error code when BIOS date is not present or not parsable, or CONFIG_DMI=n. Additionally, during the move, add a bit of documentation.
