A method an apparatus for providing capability information to a shared controller. In one embodiment, a peripheral bus host controller may be shared by a plurality of peripheral devices coupled to a peripheral bus. The peripheral devices may include coder/decoder (codec) circuitry, and may be implemented using a riser card. The host controller may be configured to query the bus for peripheral devices by reading each address on the bus. During the querying process, the host controller may detect one or more peripheral devices coupled to the bus. Following the completion of the querying of the bus, the host controller may then begin reading configuration information from each of the detected devices. 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.

A method for dynamically allocating link width of a riser card is disclosed. The method is suitable for a system including a riser card. In the present method, the number and the positions of cards inserted in the slots and functioning normally are detected so as to decide the link widths allocated for each of the cards. Next, a link width retraining procedure is executed so as to provide a proper link width for each the card to use. In this way, the present invention is able to achieve the optimization of allocating link widths without being limited by the types and the number of the cards disposed on the riser card, which is advantageous in saving the design cost of the riser card and enhancing the convenience to use and handle with the riser card.
