Don't bother too much with assembler. Only small parts of an OS are written in assembler. Most of modern OS-es are written 95% in C and OpenSolaris is no exception. > > 1. should i learn all these to learn internals of any kernel?? > 2. since most of kernels are compatible with many processors.

Just looking at the OS from a high level is like looking at a vast ocean. I'd say first understand what are the building blocks of an OS in general, like: Scheduler, Virtual Filesystem Layer, Networking etc. Pick up one topic that interests you and then see how that is implemented in the OS code. You might even start with a small topic like say the C-library implementation. How libc implements the various functionalities, how it handles the system calls etc. And if you use OpenSolaris this learning process becomes really easy because of DTrace. With DTrace you can see in real time what the running kernel is doing what functions it is calling with what arguments etc. And if you are a little daunted with learning DTrace initially, fhe latest Netbeans has a Graphical plugin for DTrace: http://www.opensolaris.org/jive/message.jspa?messageID=140567 And there is a DTrace visualization GUI called Chime: http://www.opensolaris.org/os/project/dtrace-chime/ And finally if you can't find answers to your questions BOSUG is there to hep you out :) Regards, Moinak. > > On 8/11/07, *Zoram Thanga * < Zoram.Thanga at sun.com > <mailto:Zoram.Thanga at sun.com>> wrote: > > KishoreKumar Bairi wrote: > > oh.. my god!!!! > > just now downloading the kernel for http://kernel.org its size > is 43MB > > (compressed) > > Is it possible to read such a huge size code??? > > the code for biggest project i ever did in my life was 1MB > (uncompressed) > > Now I am afraid of it a bit.
