5 / 5 page Software Usage Model From a system model viewpoint, each PCI Express port is a virtual PCI to PCI bridge device and has its own set of PCI Express configuration registers. It is through the upstream port that the BIOS or host can configure the other ports using standard PCI enumeration. The virtual PCI to PCI bridges within the PEX 8517 are compliant to the PCI and PCI Express system models. The Configuration Space Registers (CSRs) in a virtual primary/secondary PCI to PCI bridge are accessible by type 0 configuration cycles through the virtual primary bus interface (matching bus number, device number, and function number). Interrupt Sources/Events The PEX 8517 supports the INTx interrupt message type (compatible with PCI 2.3 Interrupt signals) or Message Signaled Interrupts (MSI) when enabled. Interrupts/messages are generated by PEX 8517 for hot-plug events, doorbell interrupts, baseline error reporting, and advanced error reporting. Development Tools PLX offers hardware and software tools to enable rapid customer design activity. These tools consist of a hardware module (PEX 8517RDK), hardware documentation, and a Software Development Kit (SDK). RDK The RDK hardware module includes the PEX 8517 with one x4 (card-edge slot) port and three additional x4 ports (see Figure 7). The RDK is available with x4 card edge connector and adapters for x1 edge connectors are available to plug the RDK into smaller slots. The PEX 8517RDK hardware module can be installed in a motherboard, used as a riser card, or configured as a bench-top board. The PEX 8517RDK can be used to test and validate customer software. Additionally, it can be used as an evaluation vehicle for PEX 8517 features and benefits. SDK The SDK tool set includes: - Linux & Windows drivers - C/C++ Source code, Objects, libraries - User’s Guides & Application examples PLX Technology, Inc. 870 W.
