Driver Module : serial/8250.c ReCompile

[peioazkarate]

Hi,

I have problems with a custom serial card, PCI&16550A UART. To find the bug I would like modify the serial driver 8250.c, compile alone and unload-load the driver.

Actually, I've a custom configured kernel (Ubuntu 7.10/kernel 2.6.22.9) with the serial driver defined as "M" module instead "Y" integrated into the kernel.

Well, now I see the driver with "lsmod", I can load-unload with "rmmod" and "insmod".

The question is, how can I compile the serial driver without compiling whole kernel ?, which makefile or util could I use ?.

Best regards,

I too am trying to tweak a custom driver and wish to compile only the driver module and not the entire kernel. I found this link but can not confirm that the procedure is working as of yet. Link

Please post if you have made any progress. Thanks
