Linux 中的设备有2种类型:字符设备(无缓冲且只能顺序存取).块设备(有缓冲且可以随机存取).每个字符设备和块设备都必须有主.次设备号,主设备号相同的设 备是同类设备(使用同一个驱动程序).这些设备中,有些设备是对实际存在的物理硬件的抽象,而有些设备则是内核自身提供的功能(不依赖于特定的物理硬件, 又称为"虚拟设备").每个设备在 /dev 目录下都有一个对应的文件(节点).可以通过 cat /proc/devices 命令查看当前已经加载的设备驱动程序的主设备号.内核能够识别的所…

    一般来说,车载导航主机都需要外接若干个UART的外设,如支持HFP的蓝牙模块.与原车通信的CAN解码盒模块.u-blox的GPS模块和DVD机芯等.早年使用Telechips TCC8902+WinCE6.0的方案,该芯片串口比较多,基本够用.最后实在不够时想了一招,动态复用调试串口,参见<WinCE下调试串口的动态复用>.后来改用RK3188+Android做车机,RK3188没那么多串口,于是将所有串口外设都接到了STM32上,甚至把触摸屏和收音机等IIC的设备也一并接了过去.ST…

背景 前段时间在测试docker的网络性能的时候,发现了一个veth的性能问题,后来给docker官方提交了一个PR,参考set tx_queuelen to 0 when create veth device,引起了一些讨论.再后来,RedHat的网络专家Jesper Brouer 出来详细的讨论了一下这个问题. 可以看到,veth设备qdisc队列,而环回设备/桥接设备是没qdisc队列的,参考br_dev_setup函数. 内核实现 在注册(创建)设备时,qdisc设置为noop_qdis…
