C Allocator for flat memory console system

[AndrewAPrice]

I'm looking for a decent C memory allocator for my console. I've done research and know of a few memory allocators (liballoc, dlalloc coming to mind) but they require that an operating system or an overlord (lack of a better word ) to provide pages to use. I know I could fake paging easily using a simple bitmap, but I was wondering if there was a mature allocator which was designed to work with flat memory addressing without the extra overhead.

In the BEST case situation, I'd like a system where I can say "use memory 1MB to 24MB for malloc, use memory 24MB to 4GB for hmalloc (hardware malloc)", but I know it won't be that easy (I'm thinking I'll need two memory allocators working simultaneously).

Hi,

Dlmalloc doesn't require paging. The stock dlmalloc.c just requires one function from the kernel iirc - sbrk (it can use mmap too). Sbrk is of course perfect for a linear address space. It should just work "out of the box" for you.

Cheers,
