what percentage of system memory is occupied by Linux Kernel?

The kernel does not take a percentage of the RAM.

I believe a typical kernel uses about 16709KiB

Why do you ask?

Hi chap,I am learning Linux Device Drivers .so I am curious to know about the internals of Kernel man.

How many years have you got?

Do you know C or C++?


If you haven't already done so you might want to read the kernel source.

nope Man,

actually I am still learing writing device drivers for char devices loading the KErnel code into the kernel.loading the object code using the insmod and removing the module using rmmod and etc,
I found it very very interesting

and I do know c and c++.

Have you tried modprobe yet?

Ok good C && C++ will come in handy :-D

Another thing that will come in handy is if you've played with assembly on a simple microprocessor. Helped me out a lot more than I was expecting.

Indeed knowing assembly certainly helps.

Knowing other languages and having an in-depth knowledge of Unix / Linux helps enormously.

Yup, learning the internals of the beast is the rub, so to speak. Just sit down, start reading through it, search online from time to time when the code is poorly or not documented. Worked wonders for me in my Unix Filesystems course, however I primarily dealt with, of course, filesystems, the caches it hits (dcache, icache, and they both hit the slab), and a little of the disk drivers stuff for good measure.

Just dig in and give it hell. It's immensely rewarding.

Aye, exactly! :-D

Great advice!

Why can't I do that????

I damn you college, damn you mecha engineering and damn you Father Time!!!!!

I will have to clone myself

If I want to make my own opengl game+game engine what will I need? xD

OpenGL + SDL. Not only does it give you very nice frameworks to start with, but if the fancy strikes you, it's trivial to port to Windows, MacOS, Mac OSX, BeOS, *BSD, Solaris, IRIX, QNX, and others.

Good stuff, if only it could work it's way into more dev houses we'd see many more games for Linux and the other OS's

And look at Mechanical Engineering this way: at least your jobs aren't getting exported elsewhere...

Great suggestions :-D

Cross platform libraries rock!
