 PCIe® Configuration Environment

 This chapter describes the PCIe configuration space for a CAIA-compliant device. The configuration facilities described in these sections are compatible with the PCIe Generation 3 architecture and allow system software to set the base address, the message signaled interrupt (MSI-X) capabilities, and various other configuration parameters for the CAIA-compliant device. In addition, the following sections describe the procedure to verify that the PCIe device is CAIA compliant and is signed by an authorized vendor. Collectively, these facilities are called the PCIe Configuration Environment (PCE).
