Proposed fix for Issue #74 "Need support for Linux AER driver's recovery sequence for fatal AERs" #75

Closed dinderieden closed 4 years ago

dinderieden commented 5 years ago

Refer to Issue #74 for problem description. Fix includes: 1) Add call to "pci_save_state()" in switchtec_pci_probe. 2) Add AER "error_detected" entry point, which disables PCI device before link reset is done. 3) Add AER "slot_reset" entry point, which reenables PCI device after link reset and clears other device state. 4) Add AER "resume" entry point, which does additional cleanup to clear AER registers state.

Should probably squash those, commits: no sense reviewing one commit that gets fixed in a subsequent commit. But otherwise, still looks fine to me.

OK, I've squashed the commits.
