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 8604 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 8604 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 8604 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 8604
Rapid Development Kit (RDK), hardware documentation, and
a Software Development Kit (also available at
RDK
The PEX 8604RDK is a hardware module containing the
PEX 8604 which plugs right into your system (Figure 8). The
PEX 8604RDK hardware module can be installed in a
motherboard, used as a riser card, or configured as a bench-top
board. The PEX 8604RDK can be used to test and validate
customer software. Additionally, it can be used as an
evaluation vehicle for PEX 8604 features and benefits.
