Software Usage Model
The PEX8615 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 PEX8615 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.
Interrupt Sources/Events
The PEX 8615 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 8615 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 PEX 8615
Rapid Development Kit (RDK), hardware documentation, and
a Software Development Kit (also available at
RDK
The PEX 8615RDK is a hardware module containing the
PEX 8615 which plugs right into your system (Figure 8). The
PEX 8615RDK hardware module can be installed in a
motherboard, used as a riser card, or configured as a bench-top
board. The PEX 8615RDK can be used to test and validate
customer software. Additionally, it can be used as an
evaluation vehicle for PEX 8615 features and benefits.
