SMBIOS Type 11 strings

Synopsis

/sys/firmware/dmi/entries/11-*/raw

Description

Various OS components process SMBIOS Type 11 vendor strings that a virtual machine manager (VMM) may set and a virtual machine (VM) receives. SMBIOS Type 11 vendor strings may play a similar role as kernel-command-line(1) parameters but generally are under control of the VMM rather than the boot loader or UKI.

For details on SMBIOS Type 11 see the System Management BIOS[1] specifications.

Core OS Command Line Arguments

The following strings are supported:

io.systemd.credential:CREDENTIAL=VALUE, ā€‰io.systemd.credential.binary:CREDENTIAL=VALUE

This allows passing additional system credentials into the system, in textual or binary (Base64) form. See systemd.exec(5) and System and Service Credentials[2] for details.

io.systemd.stub.kernel-cmdline-extra=CMDLINE

This allows configuration of additional kernel command line options, and is read by the kernel UEFI stub. For details see systemd-stub(1).
