* [PATCH] unify PFN_* macrosDave Hansen2006-03-2723-68/+29
| | | | | | | | | | | | | | | | | | | | Just about every architecture defines some macros to do operations on pfns. They're all virtually identical. This patch consolidates all of them. One minor glitch is that at least i386 uses them in a very skeletal header file. To keep away from #include dependency hell, I stuck the new definitions in a new, isolated header. Of all of the implementations, sh64 is the only one that varied by a bit. It used some masks to ensure that any sign-extension got ripped away before the arithmetic is done. This has been posted to that sh64 maintainers and the development list. Compiles on x86, x86_64, ia64 and ppc64.

| | | | | | | | | | | | | | | | | Helper functions for for_each_online_pgdat/for_each_zone look too big to be inlined. Speed of these helper macro itself is not very important.

| | | | | | | | | | | | | | Because pgdat_list was linked to pgdat_list in *reverse* order, (By default) some of arch has to sort it by themselves. for_each_pgdat has gone..for_each_online_pgdat() uses node_online_map, which doesn't need to be sorted.

* [PATCH] for_each_online_pgdat: for_each_bootmemKAMEZAWA Hiroyuki2006-03-272-10/+30
| | | | | | | | | | | | | | | | Add a list_head to bootmem_data_t and make bootmems use it. bootmem list is sorted by node_boot_start. Only nodes against which init_bootmem() is called are linked to the list. (i386 allocates bootmem only from one node(0) not from all online nodes.) A summary: 1. for_each_online_pgdat() traverses all *online* nodes. 2. alloc_bootmem() allocates memory only from initialized-for-bootmem nodes.

* [PATCH] define for_each_online_pgdatKAMEZAWA Hiroyuki2006-03-272-51/+61
| | | | | | | | | | | | | | | | | | | | | | This patch defines for_each_online_pgdat() as a replacement of for_each_pgdat() Now, online nodes are managed by node_online_map. But for_each_pgdat() uses pgdat_link to iterate over all nodes(pgdat). This means management structure for online pgdat is duplicated. I think using node_online_map for for_each_pgdat() is simple and sane rather ather than pgdat_link. New macro is named as for_each_online_pgdat(). Following patch will fix callers of for_each_pgdat(). The bootmem allocater uses for_each_pgdat() before pgdat initialization. I don't think it's sane. Following patch will fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are 3 memory models, FLATMEM, DISCONTIGMEM, SPARSEMEM.

This patch adds asm-generic/memory_model.h, which includes generic page_to_pfn(), pfn_to_page() definitions for each memory model. When CONFIG_OUT_OF_LINE_PFN_TO_PAGE=y, out-of-line functions are used instead of macro. This is enabled by some archs and reduces text size.

* [PATCH] sched: new sched domain for representing multi-coreSiddha, Suresh B2006-03-2714-11/+186
| | | | | | | | | | | | | | | | | | | | | | | | | Add a new sched domain for representing multi-core with shared caches between cores. Consider a dual package system, each package containing two cores and with last level cache shared between cores with in a package. If there are two runnable processes, with this appended patch those two processes will be scheduled on different packages. On such systems, with this patch we have observed 8% perf improvement with specJBB(2 warehouse) benchmark and 35% improvement with CFP2000 rate(with 2 users). This new domain will come into play only on multi-core systems with shared caches. On other systems, this sched domain will be removed by domain degeneration code. This new domain can be also used for implementing power savings policy (see OLS 2005 CMP kernel scheduler paper for more details.. I will post another patch for power savings policy soon) Most of the arch/* file changes are for cpu_coregroup_map() implementation.

The affected code is used in the TASK_INTERACTIVE macro. The code is: #define SCALE(v1,v1_max,v2_max) \ (v1) * (v2_max) / (v1_max) which is used in this way: SCALE(TASK_NICE(p), 40, MAX_BONUS) Comments in the code says: * This part scales the interactivity limit depending on niceness. * * We scale it linearly, offset by the INTERACTIVE_DELTA delta. * Here are a few examples of different nice levels: * * TASK_INTERACTIVE(-20): [1,1,1,1,1,1,1,1,1,0,0] * TASK_INTERACTIVE(-10): [1,1,1,1,1,1,1,0,0,0,0] * TASK_INTERACTIVE( 0): [1,1,1,1,0,0,0,0,0,0,0] * TASK_INTERACTIVE( 10): [1,1,0,0,0,0,0,0,0,0,0] * TASK_INTERACTIVE( 19): [0,0,0,0,0,0,0,0,0,0,0] * * (the X axis represents the possible -5 ... 0 ... +5 dynamic * priority range a task can explore, a value of '1' means the * task is rated interactive.) However, the current code does not scale it linearly and the result differs from the given examples. If the mathematical function "floor" is used when the nice value is negative instead of the truncation one gets when using integer division, the result conforms to the documentation.

| | | | | | | | | | | | Cache_fresh is now only used in cache.c, so unexport it. Part of cache_fresh (setting CACHE_VALID) should really be done under the lock, while part (calling cache_revisit_request etc) must be done outside the lock. So we split it up appropriately.

* [PATCH] knfsd: An assortment of little fixes to the sunrpc cache codeNeilBrown2006-03-271-6/+8
| | | | | | | | | | | | | | | | | | - in cache_check, h must be non-NULL as it has been de-referenced, so don't bother checking for NULL. - When a cache-item is updated, we need to call cache_revisit_request to see if there is a pending request waiting for that item. We were using a transition to CACHE_VALID to see if that was needed, however that is wrong as an expired entry will still be marked 'valid' (as the data is valid and will need to be released). So instead use an off transition for CACHE_PENDING which is exactly the right thing to test. - Add a little bit more debugging info.
