Hi, I'm trying to use i350 adapter with a hardware 1pps signal input on a SDP pin.
I'm testing on kernel 5.19(i350 hardware ts capture function was announced to be supported since kernel 5.17), using 'ts2phc' program could capture the 1PPS input event, but it failed to write time adjustment to the nic. Then I looked into igb driver source code, found these two function 'igb_ptp_adjtime_82576' and 'igb_ptp_settime_82576' calculated the target timecounter value, but doesn't write the target value to nic register. In contrast to i210 routine which works fine,'igb_ptp_adjtime_i210()' calls 'igb_ptp_write_i210()' method to write target time value to SYSTIM registers. Did I miss something, or the igb_ptp driver is currently broken for i350?
