Hi all, I have gone through the kernel/kernel/printk.c file. And i have the following questions.. I have some rough idea of several things, but i need to conform them 1) What is a console driver? --> My idea is it allows the kernel to input or output the characters to or from a particular device. 2) Why so many command-line consoles are needed? --> (if first qn is right...why cant u use single console to several devices) 3) What is a boot console & real console? 4) How to know how many number of consoles are running at a time? 5) In the boot command line we will pass one console name "console=ttyXXX", other than that where the remaining consoles are being registered? Please answer these questions so that i can have furthur understanding Thank you all.. -- With regards, Sandeep Kumar Anantapalli,
