Revision 92214be5979c0961a471b7eaaaeacab41bdf456c authored by Rahul Rameshbabu on 14 November 2023, 21:58:42 UTC, committed by Jakub Kicinski on 16 November 2023, 06:34:31 UTC
Previously, mlx5e_ptp_poll_ts_cq would update the device doorbell with the
incremented consumer index after the relevant software counters in the
kernel were updated. In the mlx5e_sq_xmit_wqe context, this would lead to
either overrunning the device CQ or exceeding the expected software buffer
size in the device CQ if the device CQ size was greater than the software
buffer size. Update the relevant software counter only after updating the
device CQ consumer index in the port timestamping napi_poll context.
Log:
mlx5_core 0000:08:00.0: cq_err_event_notifier:517:(pid 0): CQ error on CQN 0x487, syndrome 0x1
mlx5_core 0000:08:00.0 eth2: mlx5e_cq_error_event: cqn=0x000487 event=0x04
Fixes: 1880bc4e4a96 ("net/mlx5e: Add TX port timestamp support")
