Is there a kernel API to do so? This is useful in cases where an (unrecoverable) card error may not be detected by the PCI controller. There's some more/less generic error handling & recovery callbacks for drivers, which are based on EEH on IBM powerpc servers, and afaik there's some level of native AER-based implementation for other architectures. Look for pci_ers_* and PCI_ERS_* in the headers. I am not familiar with the exact capabilities of the non-EEH implementation.
