pcistub_reset_dev() just tries slot or bus reset but not FLR since it is being checked and executed by pci_reset_function_locked() if supported. May be we can add FLR reset code to pcistub_reset_dev() and try FLR first before fall-back toFurthermore, contrary to what you claim in your reply to Pasi, I can't see where you try an actual FLR first - you go straight to pci_probe_reset_{slot,bus}(). If you actually tried FLR first, only falling back to the other methods as "emulation", I could certainly agree with the file name chosen.Currently, multiple resets are being invoked (independently) in the context of "xl attach/detach/shutdown/reboot".- pci_reset_function_locked (invoked by pcistub_put_pci_dev()) This function tries various PCI reset methods including FLR. - pcistub_reset_dev (called by toolsstack based on "do_flr" attribute)While related in a certain way, I can't really see how this addresses the comment.
slot/bus reset. Cheers GOVINDA
