Hi, I am trying to migrate from ptp2 to ptp4l currently. Using wired networking I got everything to work quite well using software timestamping yet and get very good results. But I also need sync via wifi (I am aware the results will not be as good as via cable, but through ptp2 I was able to achieve at least 100us accuracy). Now it seems that the wifi stack in recent linux kernels is not supporting SOF_TIMESTAMPING_TX_SOFTWARE at all. But this seems to be a hard requirement for using ptp4l with software timestamping, right? I am just wondering how ptp4l was running on a wireless device in this discussion: http://permalink.gmane.org/gmane.comp.linux.ptp.user/295
I'd be glad about any hints how to get ptp4l working with a wireless device. Actually I am using a rtl8192cu device right now. Are there some kernel patches around implementing SOF_TIMESTAMPING_TX_SOFTWARE for wireless devices maybe? -Julian ------------------------------------------------------------------------------ _______________________________________________ Linuxptp-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linuxptp-users
