Abstract
A technique for rebalancing performance levels of one or more add-in cards is presented. Rebalancing occurs whenever a hot-plug event occurs and a change in status of a mismatch condition occurs. For example, if an add-in card is inserted that is unable to operate at the current performance level, rebalancing of the performance level occurs. Thus, for an insertion event, the performance level of all cards may be lowered. Alternatively, if an add-in card is removed and a mismatch is resolved, rebalancing of the performance level occurs. Thus, for a removal event, the performance level may be increased. The rebalancing includes disabling any enabled cards and enabling all cards at a different performance level. In one embodiment, the cards are sorted according to highest performance level available and enabled in an order of lowest to highest of the highest performance level available.
