Once upon a time, there was a low latency option for serial ports. At some point, it was removed. In 2015, an attempt was made to restore some kind of low latency performance. https://www.spinics.net/lists/linux-serial/msg17767.html This went nowhere, but in 2019 another attempt was made. https://lore.kernel.org/lkml/20190110101232.9398-1-o.rem...@pengutronix.de/ HTH, Richard _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
