Lack of this result in smaller timestamp error window which cause error during phc2sys execution on E825 NICs: phc2sys[1768.256]: ioctl PTP_SYS_OFFSET_PRECISE: Invalid argument This problem was introduced in the cited commit which omitted setting use_nsecs to true when converting the ice driver to use convert_base_to_cs(). Testing hints (ethX is PF netdev): phc2sys -s ethX -c CLOCK_REALTIME -O 37 -m phc2sys[1769.256]: CLOCK_REALTIME phc offset -5 s0 freq -0 delay 0 Fixes: d4bea547ebb57 ("ice/ptp: Remove convert_art_to_tsc()") Signed-off-by: Anton Nadezhdin Reviewed-by: Aleksandr Loktionov Reviewed-by: Arkadiusz Kubalewski Tested-by: Rinitha S (A Contingent worker at Intel) Signed-off-by: Tony Nguyen --- diff --git a/drivers/net/ethernet/intel/ice/ice_ptp.c b/drivers/net/ethernet/intel/ice/ice_ptp.c index b79a148ed0f28..55cad824c5b9f 100644 --- a/drivers/net/ethernet/intel/ice/ice_ptp.c +++ b/drivers/net/ethernet/intel/ice/ice_ptp.c @@ -2299,6 +2299,7 @@ static int ice_capture_crosststamp(ktime_t *device, ts = ((u64)ts_hi << 32) | ts_lo; system->cycles = ts; system->cs_id = CSID_X86_ART; + system->use_nsecs = true; /* Read Device source clock time */ ts_lo = rd32(hw, cfg->dev_time_l[tmr_idx]);
