CONFIG_DMI: Enable support for SMBIOS (DMI) tables

General informations

The Linux kernel configuration item CONFIG_DMI has multiple definitions:

Enable support for SMBIOS (DMI) tables found in arch/arm64/Kconfig

The configuration item CONFIG_DMI:

• prompt: Enable support for SMBIOS (DMI) tables
• type: bool
• depends on: CONFIG_EFI
• defined in arch/arm64/Kconfig
• found in Linux kernels: 3.19, 4.0–4.20, 5.0–5.16, 5.17-rc+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.

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: 4.13–4.20, 5.0–5.16, 5.17-rc+HEAD

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.

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, 4.0–4.20, 5.0–5.16, 5.17-rc+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 DMI scanning found in arch/mips/Kconfig

The configuration item CONFIG_DMI:

• prompt: Enable DMI scanning
• type: bool
• depends on: CONFIG_MACH_LOONGSON64
• defined in arch/mips/Kconfig
• found in Linux kernels: 5.7–5.16, 5.17-rc+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.
