Arch-neutral SMBIOS 3.x (DMI) table builder.
In firmware-less Linux direct boot there is no UEFI/PCAT firmware to
synthesize SMBIOS tables, so the loader must build them itself. This module
builds a SMBIOS 3.1 entry point (_SM3_) and a minimal structure table
(Type 0 BIOS, Type 1 System, Type 127 End-of-table). The caller decides
where the structure table lives in guest memory and how the entry point is
delivered to the guest (x86 F-segment scan vs. aarch64 EFI configuration
table).
Structs§
- Built
Smbios - The built SMBIOS blobs, ready to be placed in guest memory.
- Smbios
Bios Info - BIOS Information (SMBIOS Type 0).
- Smbios
System Info - System Information (SMBIOS Type 1).
- Smbios
Tables - Aggregate of the SMBIOS structures to build. The caller supplies all of the identity strings and the system UUID.
Constants§
- ENTRY_
POINT_ SIZE - Size in bytes of the SMBIOS 3.1 entry point (
_SM3_). Callers that place the entry point and structure table separately (e.g. the aarch64 EFI configuration-table path) use this to reserve space for the entry point before knowing the structure table’s address.
Functions§
- build
- Builds the SMBIOS entry point and structure table.
