Interrupt Sources/Events
Software Usage Model
The PEX 8609 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 8609 for Hot-Plug events, doorbell
interrupts, baseline error reporting, and advanced error
reporting.
The PEX8609 is a multi-function device. Function 0
implements the function of a transparent PCI Express switch
while Function 1 implements the endpoint functionality of the
DMA. 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 DMA function of
the PEX8609 implements a Type 0 header, same as an
endpoint, and requires a driver. The driver for the DMA
function is available from PLX and included in the SDK.
RDK
Development Tools
The PEX 8609RDK is a hardware module containing the
PEX 8609 which plugs right into your system (Figure 8). The
PEX 8609RDK hardware module can be installed in a
motherboard, used as a riser card, or configured as a bench-top
board. The PEX 8609RDK can be used to test and validate
customer software. Additionally, it can be used as an
evaluation vehicle for PEX 8609 features and benefits.
PLX offers hardware and software tools to enable rapid
customer design activity. These tools consist of a PEX 8609
Rapid Development Kit (RDK), hardware documentation, and
a Software Development Kit (also available at
www.plxtech.com/sdk).
