As per code in Linux PCIe driver the function level reset is done by writing “1” to “reset” under sysfs interface. e.g. “echo 1 > /sys/bus/pci/devices/<interface id> /reset “ As function level reset is not triggered via the PCIe device driver how PCIe device driver can get the notification of the function level reset(FLR)? ^ permalink raw reply [flat|nested] 3+ messages in thread

Driver's wishing to be notified of the reset can implement the pci_error_handlers .reset_prepare() and .reset_done() callbacks for the notification. ^ permalink raw reply [flat|nested] 3+ messages in thread
