Other Parts Discussed in Thread: 66AK2H14
在示例程序中,网卡发送队列采用了648,channel用了8,当向648号push一个descriptor后,发送成功后,中断报到哪里去了?是netcp的pktdma的disctributor,还是qmss的,还是会直接上报给cpu?
谢谢。

不知道你用的是K2哪款DSP,建议可以查找该款DSP对应的datasheet,在interrupt 这章可以找到该event的路由对应关系。
313 应该是指PA PacketDMA 的starvation event,
313 NETCP_PKTDMA_INT0 Packet Accelerator Packet DMA starvation interrupt
按QMSS starvation event理解,这个是接收侧的event。
