Hello,
This query is regarding Function level reset feature for SRIOV.
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)?

Just FYI, FLR support is independent of SRIOV.

Driver's wishing to be notified of the reset can implement the
pci_error_handlers .reset_prepare() and .reset_done() callbacks for the
notification.
