Abstract
Embodiments of systems and methods to determine all of the Functions that are associated with a multi-Function Peripheral Component Interconnect/Compute Express Link (PCIe/CXL) Field Replaceable Unit (FRU) for use in SPDM authentication of a PCIe/CXL FRU are disclosed. According to one embodiment, a multi-Function PCIe/CXL FRU includes multiple Functions that each are represented by a unique Device/Function path. A PCIe/CXL FRU includes computer-executable program instructions that cause it to receive a request from a Security Protocol and Data Model (SPDM) requester to obtain information about a plurality of Functions associated with the PCIe/CXL FRU, and respond to the request by sending a list of Device/Function paths to the SPDM requester. Each Device/Function path indicates the Function and the path to the Function associated with the PCIe/CXL FRU.
