Android kernel to print information about the

android kernel debug

Prawn:
I want to make Android system boot print out the kernel at boot stage serial print all the information he printed information is printk () to write out the form. But in the serial see all the information when printing starts normally, if I want to see all the printed information, such as how to modify it should source printk??? (KERN_NOTICE "Kernel command line:% s \ n", boot_command_line); Such printing information, how can print out the serial port it? ? Is not this debugging information, and in some places to do the relevant definition? ? ?
