Serial Console Driver as a Loadable Module

Can a linux 2.6 serial console driver that registers itself using the console_initcall() macro be developed as a loadable module or must it be compiled in-kernel?

serial console module can be initialize also inside the UART driver also if UART supports serial console then UART driver structure's cons field would be pointing to serial console.

As described in the kernel documentation there needs to be a system console driver which is called during the initialization phase.

So if you want default system console support for the serial drivers, you need to have them in-kernel. See drivers/tty/serial/Kconfig for the existing drivers.

This discussion might be also interesting for you.
