Abstract
In one embodiment, a system comprises at least one processor and a peripheral interface controller coupled to the processor. Further coupled to receive transactions from a peripheral interface, the peripheral interface controller is configured to accumulate freed credits for a given transaction type of a plurality of transaction types that are not yet returned to a transmitter on the peripheral interface. The peripheral interface controller is also configured to cause transmission of a flow control update transaction on the peripheral interface responsive to a number of the freed credits exceeding a threshold amount that is less than a total number of credits allocated to the given transaction type.
