6.2 VIRTUAL ISOCHRONOUS OPERATION
PERICOM SEMICONDUCTOR - Confidential
used for configuration requests. Implicit routing is being used for message routing. There are two
message groups (baseline and advanced switching). The baseline message group contains INTx
interrupt signaling, power management, error signaling, locked transaction support, slot power limit
support, vendor defined messages, hot-plug signaling. The other is advanced switching support
message group. The advanced switching support message contains data packet and signal packet
messages. Advanced switching is beyond the scope of PI7C9X130 implementation.
The r [2:0] values of the "type" field will determine the destination of the message to be routed.
baseline messages must use the default traffic class zero (TC0).
This section provides a summary of Virtual Isochronous Operation supported by PI7C9X130. Virtual
Isochronous support is disabled by default. Virtual Isochronous feature can be turned on with setting bit
[26] of offset 40h to one. Control bits are designated for selecting which traffic class (TC1-7) to be
used for upstream (PCI Express-to-PCI).
and message packets for downstream (PCI Express-to-PCI). If configuration, IO and message packets
have traffic class other than TC0, PI7C9X130 will treat them as malformed packets. PI7C9X130 maps
all downstream memory packets from PCI Express to PCI transactions regardless the virtual isochronous
operation is enabled or not.
