diclophis / contig_alloc.c

Created January 2, 2011 22:27 — forked from karthick18/contig_alloc.c

	/*
	* A simple on-demand based mmap alloc-only proof-of-concept to just check out the possibilities of having a
	* single giant MAP_FIXED allocation for a process that may not need to call free at all and just work with a
	* contiguous allocation space
	*
	* A mmap contiguous hole space is reserved with a PROT_READ and then individual pages overridden with
	* PROT_WRITE on page faults in sigsegv handler which mmaps the faulting address space.
	*
	* As a test, a 1 GIG file is created and then read into the memory allocated from the contiguous vma which is a
	* brain-dead linear allocator from the address space as there are no requirements to free memory here.
