Timestamping support in iwlwifi driver.

Shm — Mon, 12 Oct 2020 09:54:03 GMT

Hello All,

I have a Intel WiFi chipset AX200 and I wanted to implement linuxptp on the wireless interface(wlp3s0) of my device.

When I check ethtool -T wlp3s0 , it gives

$ethtool -T wlp3s0
Time stamping parameters for wlp3s0:
Capabilities:
software-receive (SOF_TIMESTAMPING_RX_SOFTWARE)
software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
PTP Hardware Clock: none
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none

As per linuxptp documentation, SOF_TIMESTAMPING_TX_SOFTWARE is required in order to configure ptp on any interface. Above,we can see that SOF_TIMESTAMPING_TX_SOFTWARE is missing and we wanted to know whether it is required in order to configure PTP on the wireless interface ?

Also ,we are aware that the board is time certified so it must really support both soft and time stamping.We wanted to know whether iwlwifi provides software/hardware timestamping facility and if it provides, what is the way to enable it? Are any additional code changes required to enable it?

My linux kernel version is 5.4 and below is the outputs of lspci and dmesg.

Thanks in advance.

Hello Shm,

Thank you for posting on the Intel® communities.

Interesting, I would like to further investigate this for you. Therefore, I would appreciate if you could provide the additional information:

What is your Linux* distro?
What are the steps to replicate this behavior?
What troubleshooting steps have you performed so far?

Please type the following commands and share the results generated:

1. modinfo iwlwifi

2. lsmod | grep iwlwifi

3. dmesg | grep ASSERT

If the output is empty with the last command provided, please follow this link.

Hello Esteban ,

Thanks for the reply.

I want to use linuxptp for time synchronization. The linuxptp documentation says that SOF_TIMESTAMPING_TX_SOFTWARE is necessary for it. When I execute $ethtool -T wlp3s0 on my wireless interface , I do not see this flag.

Are there any other methods to enable timestamping in iwlwifi driver? Can you point me to code in iwlwifi where timestamping is implemented or enabled.

My linux kernel version is 5.4

Hello Shm,

I would like to provide an update on this thread.

I need to inform you that the iwlwifi driver does not support SOF_TIMESTAMPING_TX_SOFTWARE.

If the implementation of the linuxptp compulsorily requires the “SOF_TIMESTAMPING_TX_SOFTWARE”, then unfortunately it won't be possible.

I hope that theinformation provided will help to answer your concern.

Thanks for the reply. It was very useful.

We also wanted to know whether iwlwifi supports hardware time stamping.

Thanks in advance.

Hello Shm,

Thank you for your patience.

I would like to provide an update on this matter.

After confirming the information on my side I need to inform you that the iwlwifi driver does not support Hardware time stamping.

I hope that the information provided about the Software/Hardware Time stamping helps answering any concern that you may have.

If you have any additional question please let me know and I will be more than glad to assist you.

Hello,

Thanks for your reply. It was very useful.

I wanted to get few more informations from your side.

Does the hardware of AX200 itself has internal clock so that the frames could be timestamped?
There has to be a way for the frames to get timing info.Is it from Kernel?

Thanks in advance.

Hello Shm,

Thank you so much for your patience.

I’m still working on gathering this information for you.

However, I would appreciate if you could confirm the following:

Are you working in a custom design? Are you a developer?
What is the reason for the enabling timestamping in iwlwifi driver?

I will be waiting for your response.

Hello,

Yes I am a developer and we are trying to time synchronise the WiFi6 AP and WiFi6 STA's as part of our research project.

Hello @Shm

Thank you for your patience in this matter.

After checking this further and since this is a specific question for Wi-Fi and Linux operating systems, our recommendation is to address these inquiries to the Linux community/support and to your Original Equipment Manufacturer (OEM) for proper assistance.

Having said that, we will proceed to close this inquiry now. Thank you for your understanding.
