UEFI CSP
The UEFI configuration service provider (CSP) interfaces to UEFI's Device Firmware Configuration Interface (DFCI) to make BIOS configuration changes. This CSP was added in Windows 10, version 1809.
Note
The UEFI CSP version published in Windows 10, version 1803 is replaced with this one (version 1809).
Note
The production UEFI CSP is present in 1809, but it depends upon the Device Firmware Configuration Interface (DFCI) and UEFI firmware to comply with this interface. The specification for this interface and compatible firmware is not yet available.
The following diagram shows the UEFI CSP in tree format.
The following list describes the characteristics and parameters.
DeviceIdentifier
Retrieves XML from UEFI that describes the device identifier.
Supported operation is Get.
Identity
Node for identity certificate operations.
Supported operation is Get.
Identity/Current
Retrieves XML from UEFI that describes the current UEFI identity certificate information.
