This kind of\nmem_map[] is needed by discontiguous memory machines (like in the old\nCONFIG_DISCONTIGMEM case) as well as memory hotplug systems. Sparsemem\nreplaces DISCONTIGMEM when enabled, and it is hoped that it can eventually\nbecome a complete replacement.\n\nA significant advantage over DISCONTIGMEM is that it\u0027s completely separated\nfrom CONFIG_NUMA. When producing this patch, it became apparent in that NUMA\nand DISCONTIG are often confused.\n\nAnother advantage is that sparse doesn\u0027t require each NUMA node\u0027s ranges to be\ncontiguous. It can handle overlapping ranges between nodes with no problems,\nwhere DISCONTIGMEM currently throws away that memory.\n\nSparsemem uses an array to provide different pfn_to_page() translations for\neach SECTION_SIZE area of physical memory. This is what allows the mem_map[]\nto be chopped up.\n\nIn order to do quick pfn_to_page() operations, the section number of the page\nis encoded in page-\u003eflags. Part of the sparsemem infrastructure enables\nsharing of these bits more dynamically (at compile-time) between the\npage_zone() and sparsemem operations. However, on 32-bit architectures, the\nnumber of bits is quite limited, and may require growing the size of the\npage-\u003eflags type in certain conditions. Several things might force this to\noccur: a decrease in the SECTION_SIZE (if you want to hotplug smaller areas of\nmemory), an increase in the physical address space, or an increase in the\nnumber of used page-\u003eflags.\n\nOne thing to note is that, once sparsemem is present, the NUMA node\ninformation no longer needs to be stored in the page-\u003eflags. It might provide\nspeed increases on certain platforms and will be stored there if there is\nroom. But, if out of room, an alternate (theoretically slower) mechanism is\nused.\n\nThis patch introduces CONFIG_FLATMEM. It is used in almost all cases where\nthere used to be an #ifndef DISCONTIG, because SPARSEMEM and DISCONTIGMEM\noften have to compile out the same areas of code.\n\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nSigned-off-by: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nSigned-off-by: Martin Bligh \u003cmbligh@aracnet.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nSigned-off-by: Bob Picco \u003cbob.picco@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
