    • An improved interface technology is provided that may be applied to PCI (Peripheral Component Interconnect) devices connected to a southbridge. Requests are received from at least one requestor. The request require responses to be sent back to the respective requestor. The requests are placed by the respective requestor by asserting a request signal, and the request signal is deasserted by the respective requestor when a response is sent back. A retry request may be sent to the current requestor for requesting the current requestor to deassert its request signal although a response has not yet been sent back, and to reassert the request signal later. Together with the retry request, a ready signal is sent indicating whether the request could be processed. This allows the requestor to modify its request when retrying it, if the request was not yet processed.

    • A method and apparatus for passing device configuration information to a shared controller. In one embodiment, a host controller may be configured to read configuration from one or more peripheral devices coupled to a serial bus. The peripheral devices may include coder/decoder (codec) circuitry, and may be implemented using a riser card. The host controller may employ one or more of several different techniques in order to read configuration information from the peripheral device. The configuration information at a minimum includes a device identifier, which may identify the vendor and the function of the device. Additional information needed to configure the device to communicate over the peripheral bus may also be obtained with a read of the device, or various lookup mechanisms, such as a lookup table or a tree-like data structure. After configuration information has been obtained for each device coupled to the bus, the host controller may dynamically configure each of the devices for communication over the bus, thereby allowing the flexibility to enumerate riser cards and add new functions through peripheral devices to the computer system in which the bus is implemented.
