supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

$ ethtool -T enp13s0f1
Time stamping parameters for enp13s0f1:

Hi AsheeshT,

Thank you for contacting Intel.

We appreciate you reaching out to us regarding the reported issue. Regarding your inquiry, please let us know if you have already checked the Intel® Ethernet Network Adapter E810-XXVDA4T User Guide for setup instructions:

https://www.intel.com/content/www/us/en/content-details/646265/intel-ethernet-network-adapter-e810-xxvda4t-user-guide.html?DocID=646265

Additionally, we recommend updating both the driver and firmware to the latest versions to ensure optimal functionality and compatibility.

Please let us know if you need further assistance.

Hi AsheeshT,

We hope you are doing well. We have reviewed the error messages you encountered while running ptp4l, and they indicate a few potential issues with your PTP configuration or network interface card (NIC) settings. Please review the following details and suggestions:

1. Driver Rejected Most General HWTSTAMP Filter:

This error means the hardware timestamping filter is not accepted by your driver. Please ensure your NIC supports the required hardware timestamping modes. You can verify this by running:

ethtool -T enp13s0f1

Look for supported modes such as HWTSTAMP_FILTER_PTP_V2_EVENT.

2. Timed Out While Polling for TX Timestamp:

This error suggests that the system is not receiving the expected transmit timestamps, which could be due to a driver issue or misconfiguration. To address this, consider:

• Increasing tx_timestamp_timeout: Modify your PTP configuration file to allow more time for the timestamp to be received.
• Increasing kworker Priority: Adjust the priority of kernel worker threads to ensure timely processing of timestamps.

If these steps don’t resolve the issue, it may be a driver-related problem. Please ensure you are using the latest driver version by checking with:

ethtool -i enp13s0f1

3. Configuration File and Kernel Settings:

• Verify that your ptp-gm.cfg file is correctly configured for your setup, in line with the requirements for O-RAN LLS-C1 and your specific network environment.
• Confirm that your kernel is configured with the necessary options for PTP:
  • CONFIG_PPS
  • CONFIG_NETWORK_PHY_TIMESTAMPING
  • CONFIG_PTP_1588_CLOCK

Additional Steps:

• NIC Firmware: Ensure that your NIC firmware is up to date, as updates can resolve known issues with timestamping.

If you have any further questions or require additional assistance, please do not hesitate to reach out.

Thank you for using Intel products and services.

 Hi Azeem,

I have already provided the NIC driver versions and capabilities when I opened this issue, but I am providing them again. The NIC I am using is Intel E810XXVDA4TGG1 (which is well known to provide hardware time clock for PTP), and the PTP configuration file is known to work with this NIC with different O-RU in LLS-C1 configuration. I have also tried increasing the timeout and ice driver version 1.12.7, but nothing has improved. Do you suggest any specific driver and firmware versions or kernel versions that are validated by Intel to provide reliable PTP? I am using Ubuntu 22.04.5 LTS (server) with kernel 15.0-131-generic. The Intel user guide for this NIC slightly confuses me regarding which firmware and driver versions are validated for which kernel version of ubuntu 22.04.

ethtool -i enp13s0f1
driver: ice
version: 1.13.7
firmware-version: 4.40 0x8001c96a 1.3534.0
expansion-rom-version:
bus-info: 0000:0d:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes

Hi AsheeshT,

Greetings for the day!

Please note we have reviewed the issue further and below are the details:

Please note Feature Support Matrix has details of IEEE 1588 - PTP support.

Refer Page 20 on the below link:

https://www.intel.com/content/www/us/en/content-details/630155/intel-ethernet-controller-e810-feature-support-matrix.html

IEEE 1588-PTP is supported from Driver pack 26.4.

We see your using Linux Driver 1.13.7 and NVM version 4.40 which is ok.

We recommend to update the driver and NVM firmware to the latest version using the driver pack.

Please follow the example ptp4l configuration file in Section 5.9 of E810 User guide on the below link:

https://www.intel.com/content/www/us/en/content-details/646265/intel-ethernet-network-adapter-e810-xxvda4t-user-guide.html

Please let us know if this is helpful.

We await your response to assist you further.

Thank you for using Intel products and services.
