7.14 AMD-8132™ PCI-X®Controller

The AMD-8132 PCI-X Controller is a HyperTransport tunnel that provides two PCI-X buses and two IOAPICs. These PCI-X buses may or may not be configured as hot-plug- capable, depending on the platform.

Interface

AMD-8132 has two types of interfaces, HyperTransport and PCI buses. It has two HyperTransport links, HT0 and HT1, that can connect to other HyperTransport link- capable devices. Either HyperTransport link can be set to be the upstream HyperTransport link. The PCI bus interfaces in the AMD-8132 must be connected to a PCI Bus device, which provides the Slot interfaces with which to connect devices for simulation.

Initialization and Reset State

When first initialized, AMD-8132 device is in its default state. This is described in detail in the AMD-8132 datasheet. Each bridge defaults with hot-plug functionality disabled.

When reset, AMD-8132 takes on all default register values.

The entire configuration of the AMD-8132 chipset, including all state and registers for its sub devices, is saved in the BSD.

Configuration Options

The Hot Plug tab options for AMD-8132 are to enable or disable hot-plug for each of its PCI-X bridges, as shown in Figure 7-27.You cannot enable or disable hot-plug after a simulation has already begun.
