Note that you can use the sync command to flush the buffer cache out to the storage media ( force all unwritten data out to the device drivers and, subsequently, to the storage device). 注意,可以使用sync命令将缓冲区缓存中的请求发送到存储媒体(迫使所有未写的数据发送到设备驱动程序,进而发送到存储设备)。
An on-chip data buffer storage structure and a synchronizing mechanism in multi-clock domains is used for exchanging data between network processor and MAC device. Port ready polling and active request mechanism is used for different rates of MAC devices. 提供一种片上数据缓冲存储结构和多时钟域信号同步机制实现网络处理器与MAC设备的数据交换,使用端口就绪轮询和主动请求机制实现对不同速率MAC端口的兼容。
