Hi again,

I'm starting now to think about a memory manager to my os. Is there some good info about howto writing a kmalloc and the user side malloc?

I don't know where to start.


thanks for all.

Google for dlmalloc, or Doug Lea's malloc. There's a website with some good material on how the innards of dlmalloc() work, which should give you some insight on kmalloc() too.

this might help.

Also check out http://osdever.net/, which is has plenty of MM (http://osdever.net/tutorials.php?cat=6&sort=1), as said in the Getting started page of the wikiFAQ

thank you guys.

A question about paggin, every process needs to have its own page directory? if yes, where to save them?

well, yes. With the exception of Single Address Space OSes, process get their own page directory. Most of the time (see exceptions in mystran tutorial), a process X don't need to map the directory of process Y, so all you need to keep is its physical address in your process structure: that'll be enough to switch threads once required.

thanks pype for your answear.

i'll now take a look to the you gave me and start working.

thanks once again for all
