An apparatus and method of PCIe error handling and recovery actions taken in the event of an error. An error reporting extension defines a set of commonly used actions that are taken by a device in response to the detection of an error. This minimizes the side effects of continued device operation following the occurrence of an error. The device's error handling capabilities are advertised and the system software specifies the desired device action to take upon occurrence of a particular error. The particular error handling action is defined uniquely for each PCIe function and error type, such that different errors trigger a different type of action, thereby affecting only specific device functions or the entire device, depending on the configuration. Error handling actions and control fields are placed in the extension portion of the PCI Express Advanced Error Reporting configuration space.
