A console is where the output from printk goes. > and Why it is always associated with > UART?" While console's may often be associated with a UART (typical for embedded systems) there is no need or requirement for them to be associated with a console. You can regitser a console to send the output wherever you like. > What is a serial console?? A serial console is a console driver (registered via register_console) which sends the output to a serial port, typically also allowing the serial port to be used as a tty interface. > Can there be a USB console?? Sure. I don't know if a driver for this exists yet, but if it doesn't you can always write one. There is already something called a netconsole (see Documentation/networking/netconsole.txt). This is an example of a console which isn't associated with a serial port. There is also a framebuffer console (See Documentation/fb/fbcon.txt) -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
