Kernel

[vibhory2j]

hi,

i am new os developement.i have had heard a lot about the Kernel in a os, but i don't know what a kernel is....i mean i know it is the basic interface between the applications and the hardware.but i don't know what are the ingredients of a kernel and how it is created.
is it a collection of different programs or......i am really confused and need help in it????

Thanks in advance

cheers

You might want to visit the OS FAQ which we maintain at http://www.osdev.org/osfaq2/.

The kernel is usually a binary image (or, in advanced designs, a collection of modules) that handles basic hardware abstraction.

In a "monolitic" design, the kernel handles everything from scheduling over memory management to file system handling. In a "microkernel" design, people strive to put as many of these features into seperate user-space entities, with the kernel merely handling the messaging between those entities.

More info is in the FAQ.

I would recommend doing as i do, building the most basic kernel you can (to load other binary's, ELF...) then write each individual part of the kernel seperatley. Then when the individual sections are working properly you can put them togeather to form your kernel.

Good approach. I 'd go further: first develop some tools: Linked list handling for each and everything comes in handy: develop it one time, refine it in dozens of iterations and reuse it for each and everything, where you need such algorithms -
and that's no joke: you'll need them often in kernel land.

Furthermore you'll need memorymanagement in its most basic form ...

well, I suggest you go to www.distantvoices.org and check out for the tutorials I've written - malloc and multitasking f. ex. They are hidden in the BlueIllusion OS section. It's in english, so don't worry.

The quick linkz section of this forum will reveal some help too.

stay safe

i can offer the 'what's in my kernel' document ... it's clicker-specific, for sure, but at least it will show what can be found in a kernel (and is certainly not exhaustive)

Linked lists, linked lists and double linked lists....
...and ofcourse stay cool .

thanks ,

what is the first module i need to develope to start create my own kernel.how should i approach to develope it.

cheers
