Abstract
A Peripheral Component Interconnect-Express (PCIe) port includes a PCIe link, a pending transaction counter, and an error status register. The PCIe port operates to issue a transaction on the PCIe link, determine that an endpoint device has become uncoupled from the PCIe link after issuing the first transaction, determine that a value stored in the pending transaction counter is not equal to zero in response to determining that the endpoint device has become uncoupled, and set an error bit in the error status register in response to determining that the first value is not equal to zero.
