Software Usage Model
From a system model viewpoint, each PCI Express port is a
virtual PCI to PCI bridge device with 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 8509 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).
Development Tools
PLX offers the PEX 8509RDK which includes hardware and
software tools to enable rapid customer design activity. These
tools consist of a hardware module, hardware documentation
and a Software Development Kit (SDK).
ExpressLane
The RDK hardware module includes the PEX 8509 with one
upstream x4 port and four downstream x1 ports.
The PEX 8509RDK hardware module can be installed in a
motherboard, used as a riser card, or configured as a bench-top
board.
The PEX 8509RDK can be used to test and validate customer
software. Additionally, it can be used as an evaluation vehicle
for the PEX 8509 features and benefits.
SDK

Interrupt Sources/Events
The ExpressLane PEX 8509 switch supports the INTx
interrupt message type (compatible with the PCI 2.3 Interrupt
signals) or Message Signaled Interrupts (MSI) when enabled.
Interrupts/messages are generated by the PEX 8509 for hot
plug events, baseline error reporting, and advanced error
reporting.
