Enable DMI scanning found in arch/x86/Kconfig

The configuration item CONFIG_DMI:

• prompt: Enable DMI scanning
• type: bool
• depends on: CONFIG_EXPERT
• defined in arch/x86/Kconfig
• found in Linux kernels: 2.6.26–2.6.39, 3.0–3.19, 4.0–4.18, 4.18+HEAD

Help text

Enabled scanning of DMI to identify machine quirks. Say Y here unless you have verified that your setup is not affected by entries in the DMI blacklist. Required by PNP BIOS code.

Enable support for SMBIOS (DMI) tables found in arch/arm/Kconfig

The configuration item CONFIG_DMI:

• prompt: Enable support for SMBIOS (DMI) tables
• type: bool
• depends on: CONFIG_EFI
• defined in arch/arm/Kconfig
• found in Linux kernels: 4.13–4.18, 4.18+HEAD

Help text

This enables SMBIOS/DMI feature for systems.

This option is only useful on systems that have UEFI firmware. However, even with this option, the resultant kernel should continue to boot on existing non-UEFI platforms.

NOTE: This does *NOT* enable or encourage the use of DMI quirks, i.e., the the practice of identifying the platform via DMI to decide whether certain workarounds for buggy hardware and/or firmware need to be enabled. This would require the DMI subsystem to be enabled much earlier than we do on ARM, which is non-trivial.
