Hi. there I,ve been trying to look up at more and more of the kernel as my knowledge of OS. but I can't look up about the frame allocation. please helpful about below. 1. after exec(), when process request his physical memory, how many memory is allocated or what percent(%) is allocated? and where is frame allocation function? where is frame allocation fomula? 2. when process request his memory, how memory is allocated? random or sequence, I don't know where is allocation function? 3. in vm_fault.c , VM_FAULT_READ_AHEAD is 4 and VM_FAULT_READ_BEHIND is 3. I don't know how 3 or 4 is selected?
