tty core是TTY的核心层,它抽象tty的核心数据结构,例如tty_struct、tty_driver等,提供接口给下面的discipline和tty driver层,discipline和tty driver使用tty core提供的注册接口,把discipline和tty driver注册到tty core。当用户操作设备节点的时候,tty core接收用户的请求,决定下一步是到discipline,还是tty driver层,例如...

安装之后可以通过ttyUSBx与任何usb设备进行数据传输,但是如果usb设备端接收pc下发的数据速度跟不上,比如设备端可能需要处理pc下发的数据用掉一段时间,这时tty->driver->write(tty, b, nr);可能返回0,也就是在执行usb_serial_generic_write()函数时,因为port->write_urb_busy = 1;发送正繁忙,进而会执行schedul...
When I press ctrl+c while a login shell is executing commands, the foreground process gets killed. Who sends the signal? Does TTY-driver send SIGINT to foreground process group directly? Or does the TTY-driver send SIGINT to shell and shell redirects the signal to foreground p...
