But the code is not in base. I have written a similar driver for my needs. It is much simpler and provides a notification to userland through kqueue events in the event of a change and counts the number of changes that have taken place over time. I can share the code if you want. //Oskar _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-arm To unsubscribe, send any mail to "[email protected]"
