通过sunxi_tx_poll 函数的 write1 设置启动 DMA 数据发送位,该函数触发以太网控制器开始发送已经准备好的数据帧。 void sunxi_tx_poll(void *iobase) { unsigned int value; value = readl(iobase + GETH_TX_CTL1); writel(value | 0x80000000, iobase + GETH_TX_CTL1);//0x80000000转化为二进制为31...
At first i dissabled ncq cause i read that it could be the problem, but it didnt changed anything except the error message from "failed command write fpdma queued" to the one above. I swapped my HDDs inside the bay to check if its the hdd or cable/mainboard. Didnt change so i assum...

DMA是计算机系统的一个特性,它允许设备在没有CPU干预的情况下访问主系统内存RAM,然后允许它们投入到其他任务中。人们通常使用它来加速网络流量,但它支持任何类型的拷贝。 DMA控制器是负责DMA管理的外围设备。主要在现代处理器和微控制器中能看到它。DMA有一个用于执行内
