I need to event-notify a non-RT thread with a poll(2) compatible mechanism from an RT thread, meaning the event must come via a file descriptor. I cannot use eventfd() since there's no common parent process. what would be a low-overhead method on the RT thread side? writing a socket? a pipe? Or should I rather not bother about the cost of the operation to start with? thanks in advance for any suggestions. - Michael -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
