Hello,
I would like to take a high accuracy timestamp whenever data is received on the serial port.
I think the best place to do this is in the tty_flip_buffer_push method of the tty_io.c file.
2652 void tty_flip_buffer_push(struct tty_struct *tty) 2653 { 2654 if (tty->low_latency) 2655 flush_to_ldisc((void *) tty); 2656 else 2657 schedule_delayed_work(&tty->flip.work, 1); 2658 } I would buffer the timestamps, and access them using an ioctl.
Is this the best way of doing this?
I am currently using the 2.6.15 kernel.
