Dear all, I found that ring_sw.c the poll function has to read half of the data for poll to work. Basically, you have to fill half of the ring buffer in order for poll to be triggrerred. You have to also read more than half of the data for poll to be disappeared. This would pose problems. If you have big ring buffer, the data will lost its immediacy. If you have small ring buffer, the data could lost if not buffered enough. Is that possible this poll action configurable? Or I missed anything. Thanks.
