During initialilzation, it - just adds each memory region identified during the boot process by - calls to the BIOS; as pages are requested, they are carved out of - these large blocks. The freelist is ordered by starting block - address, and allocation uses a first-fit strateby. - - The allocation function has this prototype: - - void *km_page_alloc( unsigned int count ); - - This allows the allocation of multiple contiguous pages. As pages - are freed, they are merged back into the freelist, and adjacent - free pages are coalesced into single, larger blocks. - - lib.c - This file pulls in all the individual .c files for the common - library functions in the lib/ directory. It is intended as an - alternative to having the libk.a archive file for the kernel; - instead of linking against that library, the lib.o file can - just be provided to the linker when the kernel is created, - and all the common library functions will be available. |
