Wi-Fi Configuration

Certain Intel® Wi-Fi features require platform-specific settings in addition to the standard driver and firmware package. These settings may be used to control Wi-Fi device features and platform-specific features, including settings required for regulatory compliance. The method used to deliver these settings depends on the firmware architecture of the target platform.

Configuration Methods

Platform-specific Wi-Fi settings may be delivered through different platform configuration methods, depending on the system firmware architecture. Intel modules support the following three configuration methods:

UEFI variables — firmware-provided configuration values that are accessible to software through standard UEFI services. For UEFI, integrity typically relies on firmware-enforced protection of the relevant variables, either individually or through a variable policy applied to the associated GUID namespace.

ACPI methods — expose configuration data through the ACPI interface used by the operating system. For ACPI, integrity typically relies on the ACPI tables or methods being generated by trusted platform firmware and protected by the platform boot process.

Device tree — provides platform configuration data as part of the hardware description passed during boot. For device tree, integrity typically relies on the device tree blob being included in a protected platform image and covered by the platform boot flow.
