SMBIOS-TYPE-11(7)                          smbios-type-11                          SMBIOS-TYPE-11(7)

NAME
       smbios-type-11 - 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.

STRINGS
       The following strings are supported:

       io.systemd.credential:CREDENTIAL=VALUE, 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.

           Added in version 252.

       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).

           Added in version 254.
