Hi list, I try to enable kgdb on S5PV210 using the same serial port (UART 0) with the console, but after adding "kgdboc=ttySAC0,115200 kgdbwait" I found tty_find_polling_driver returns NULL. The cause is that the poll_get_char and poll_put_char handlers are not set in static struct uart_ops s3c24xx_serial_ops. I tried google but do net found any patch for this, but maybe I lost something. Is there any patch I can get from anywhere or should I implement the functions by myself? Thanks in advance.
