Some of my friends have got together and we are trying to write a basic kernel similar to Linux. I am trying to implement the malloc function in C and I am using a doubly linked list as the primary data structure. I need to allocate memory for this link list (duh...) and I don't feel like using malloc for it. I mean I am trying to implement a malloc function and it will be kind of stupid to use malloc for it.I was just wondering is there a way to allocate memory for my list without calling malloc.
I didn't study OS design, but shouldn't the malloc() function be part of the C library, not the kernel?
That aside, I'd write it in assembly language (after all, it's pretty CPU specific, and might even be time-critical). Also, it might help flipping through Tannenbaums Operating Systems Design and Implementation, as I'm sure that there's some information in there. Minix is the implementation of the theories put forth there.
