The high-prio thread is able to queue the packet. Thus for the thread itself everthing is fine, no priority inversion for the thread. At least in my case. In my situation the transmission of the packet from the high-prio thread is delayed until the low-prio thread is scheduled again. Is there any possibility to transmit high-prio traffic and low-prio traffic over the same network interface, with limited delay for the high-prio traffic? The delay of a full ring buffer of the network device is at least limited with e.g. 10ms, this is acceptable in my application. regards, gerhard-- 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
