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 8516 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 8516 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 8516 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 8516RDK), hardware documentation, and a
Software Development Kit (SDK).

PEX 8516RDK
The RDK hardware module includes the PEX 8516 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 8516RDK hardware module
can be installed in a motherboard, used as a riser card, or
configured as a bench-top board. The PEX 8516RDK can be
used to test and validate customer software. Additionally, it
can be used as an evaluation vehicle for PEX 8516 features
and benefits.
SDK
The SDK tool set
includes:
-
Linux & Windows
drivers
-
C/C++ Source code,
Objects, libraries
-
