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(7) 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(7).
Added in version 254.
io.systemd.boot.kernel-cmdline-extra=CMDLINE
This allows configuration of additional kernel command line options
for Boot Loader Specification Type 1 entries, and is read by
systemd-boot. For details see systemd-boot(7).
Added in version 256.
