It does the following\nthings:\n\n - consolidates and enhances the spinlock/rwlock debugging code\n\n - simplifies the asm/spinlock.h files\n\n - encapsulates the raw spinlock type and moves generic spinlock\n features (such as -\u003ebreak_lock) into the generic code.\n\n - cleans up the spinlock code hierarchy to get rid of the spaghetti.\n\nMost notably there\u0027s now only a single variant of the debugging code,\nlocated in lib/spinlock_debug.c. (previously we had one SMP debugging\nvariant per architecture, plus a separate generic one for UP builds)\n\nAlso, i\u0027ve enhanced the rwlock debugging facility, it will now track\nwrite-owners. There is new spinlock-owner/CPU-tracking on SMP builds too.\nAll locks have lockup detection now, which will work for both soft and hard\nspin/rwlock lockups.\n\nThe arch-level include files now only contain the minimally necessary\nsubset of the spinlock code - all the rest that can be generalized now\nlives in the generic headers:\n\n include/asm-i386/spinlock_types.h | 16\n include/asm-x86_64/spinlock_types.h | 16\n\nI have also split up the various spinlock variants into separate files,\nmaking it easier to see which does what. The new layout is:\n\n SMP | UP\n ----------------------------|-----------------------------------\n asm/spinlock_types_smp.h | linux/spinlock_types_up.h\n linux/spinlock_types.h | linux/spinlock_types.h\n asm/spinlock_smp.h | linux/spinlock_up.h\n linux/spinlock_api_smp.h | linux/spinlock_api_up.h\n linux/spinlock.h | linux/spinlock.h\n\n/*\n * here\u0027s the role of the various spinlock/rwlock related include files:\n *\n * on SMP builds:\n *\n * asm/spinlock_types.h: contains the raw_spinlock_t/raw_rwlock_t and the\n * initializers\n *\n * linux/spinlock_types.h:\n * defines the generic type and initializers\n *\n * asm/spinlock.h: contains the __raw_spin_*()/etc. lowlevel\n * implementations, mostly inline assembly code\n *\n * (also included on UP-debug builds:)\n *\n * linux/spinlock_api_smp.h:\n * contains the prototypes for the _spin_*() APIs.\n *\n * linux/spinlock.h: builds the final spin_*() APIs.\n *\n * on UP builds:\n *\n * linux/spinlock_type_up.h:\n * contains the generic, simplified UP spinlock type.\n * (which is an empty structure on non-debug builds)\n *\n * linux/spinlock_types.h:\n * defines the generic type and initializers\n *\n * linux/spinlock_up.h:\n * contains the __raw_spin_*()/etc. version of UP\n * builds.

I did not try to build\n non-SMP kernels. That should be trivial to fix up later if necessary.\n\n I converted bit ops atomic_hash lock to raw_spinlock_t. Doing so avoids\n some ugly nesting of linux/*.h and asm/*.h files. Those particular locks\n are well tested and contained entirely inside arch specific code. I do NOT\n expect any new issues to arise with them.\n\n If someone does ever need to use debug/metrics with them, then they will\n need to unravel this hairball between spinlocks, atomic ops, and bit ops\n that exist only because parisc has exactly one atomic instruction: LDCW\n (load and clear word).\n\nFrom: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\n\n ia64 fix\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjanv@infradead.org\u003e\nSigned-off-by: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nSigned-off-by: Mikael Pettersson \u003cmikpe@csd.uu.se\u003e\nSigned-off-by: Benoit Boissinot \u003cbenoit.boissinot@ens-lyon.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "486a153f0e294f7cc735838edcb6b32e623cbe52", "tree": "f16a31eb3526968dd08aa93c12cbb211f31f2084", "parents": [ "9c8550ee25e26d14a8f0fe1b761a676e23fe3cf0", "f64a227b6b5cc1f8cc7f6ef9cc3351343636bac9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 09 15:46:49 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 09 15:46:49 2005 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/sam/kbuild \n" }, { "commit": "0037c78a96bb391635bff103d401c24459c5092d", "tree": "3f529692da923df00cdc0d81c6b02bdb4521b08a", "parents": [ "5a0773698c51fdcec7eb361b6b819669ed1d249e" ], "author": { "name": "Sam Ravnborg", "email": "sam@mars.(none)", "time": "Fri Sep 09 22:47:53 2005 +0200" }, "committer": { "name": "Sam Ravnborg", "email": "sam@mars.(none)", "time": "Fri Sep 09 22:47:53 2005 +0200" }, "message": "kbuild: frv,m32r,sparc64 introduce fake asm-offsets.h file\n\nNeeded to get them to build.\nAnd a hint to avoid hardcoding to many constants in assembler.\n\nSigned-off-by: Sam Ravnborg \u003csam@ravnborg.org\u003e\n" }, { "commit": "7bbedd521310547ca73cc77adcf61fb85723adc3", "tree": "f759d90c46bfbc48a9f396c9c6f839da11cdc6aa", "parents": [ "f44702f49056c203341badaa2cb8a706160d9119", "a04ce0ffcaf561994ecf382cd3caad75556dc499" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Sep 08 15:55:23 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Sep 08 15:55:23 2005 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/gregkh/pci-2.6 \n" }, { "commit": "085ae41f66657a9655ce832b0a61832a06f0e1dc", "tree": "215690b947b14fa18cbb2810db1a4082ad607e7a", "parents": [ "064b53dbcc977dbf2753a67c2b8fc1c061d74f21" ], "author": { "name": "David S.

These resources get linked into the\n iomem/ioport tree when PCI controllers are probed.\n\n So the hierarchy looks like this:\n\n iomem --|\n\t PCI controller 1 MEM space --|\n\t\t\t\t device 1\n\t\t\t\t\tdevice 2\n\t\t\t\t\tetc.\n\t PCI controller 2 MEM space --|\n\t\t\t\t ...\n ioport --|\n PCI controller 1 IO space --|\n\t\t\t\t\t...\n PCI controller 2 IO space --|\n\t\t\t\t\t...\n\n You get the idea. The drivers/pci/setup-res.c code allocates\n using plain iomem_space and ioport_space as the root, so that\n wouldn\u0027t work with the above setup.\n\n So I added a pcibios_select_root() that is used to handle this.\n It uses the PCI controller struct\u0027s io_space and mem_space on\n sparc64, and io{port,mem}_resource on every other platform to\n keep current behavior.\n\n2) quirk_io_region() is buggy. It takes in raw BUS view addresses\n and tries to use them as a PCI resource.\n\n pci_claim_resource() expects the resource to be fully formed when\n it gets called. The sparc64 implementation would do the translation\n but that\u0027s absolutely wrong, because if the same resource gets\n released then re-claimed we\u0027ll adjust things twice.\n\n So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()\n conversion before passing it on to pci_claim_resource().\n\n3) I was mistakedly __init\u0027ing the function methods the PCI controller\n drivers provide on sparc64 to implement some parts of these\n routines. This was, of course, easy to fix.\n\nSo we end up with the following, and that nasty SPARC64 makefile\nifdef in drivers/pci/Makefile is finally zapped.\n\nSigned-off-by: David S.

This leaves such\na device in an inaccessible state. The patch below causes the BARs\nto be restored when enabling such a device, so that its driver will\nbe able to access it.\n\nThe patch also adds pci_restore_bars as a new global symbol, and adds a\ncorrepsonding EXPORT_SYMBOL_GPL for that.\n\nSome firmware (e.g. Thinkpad T21) leaves devices in D3hot after a\n(re)boot. Most drivers call pci_enable_device very early, so devices\nleft in D3hot that lose configuration during the D3hot-\u003eD0 transition\nwill be inaccessible to their drivers.\n\nDrivers could be modified to account for this, but it would\nbe difficult to know which drivers need modification. This is\nespecially true since often many devices are covered by the same\ndriver. It likely would be necessary to replicate code across dozens\nof drivers.\n\nThe patch below should trigger only when transitioning from D3hot-\u003eD0\n(or at boot), and only for devices that have the \"no soft reset\" bit\ncleared in the PM control register. I believe it is safe to include\nthis patch as part of the PCI infrastructure.\n\nThe cleanest implementation of pci_restore_bars was to call\npci_update_resource. Unfortunately, that does not currently exist\nfor the sparc64 architecture.

This leaves such\na device in an inaccessible state. The patch below causes the BARs\nto be restored when enabling such a device, so that its driver will\nbe able to access it.\n\nThe patch also adds pci_restore_bars as a new global symbol, and adds a\ncorrepsonding EXPORT_SYMBOL_GPL for that.\n\nSome firmware (e.g. Thinkpad T21) leaves devices in D3hot after a\n(re)boot. Most drivers call pci_enable_device very early, so devices\nleft in D3hot that lose configuration during the D3hot-\u003eD0 transition\nwill be inaccessible to their drivers.\n\nDrivers could be modified to account for this, but it would\nbe difficult to know which drivers need modification. This is\nespecially true since often many devices are covered by the same\ndriver. It likely would be necessary to replicate code across dozens\nof drivers.\n\nThe patch below should trigger only when transitioning from D3hot-\u003eD0\n(or at boot), and only for devices that have the \"no soft reset\" bit\ncleared in the PM control register. I believe it is safe to include\nthis patch as part of the PCI infrastructure.\n\nThe cleanest implementation of pci_restore_bars was to call\npci_update_resource. Unfortunately, that does not currently exist\nfor the sparc64 architecture.

Before the change new areas were always\n searched from the base address on.\n\n So now new small areas are cluttering holes of all sizes\n throughout the whole mmap-able region whereas before small holes\n tended to close holes near the base leaving holes far from the base\n large and available for larger requests.\n\n 2) the free_area_cache also is set to the location of the last\n munmap-ed area so in scenarios where we allocate e.g. five regions of\n 1K each, then free regions 4 2 3 in this order the next request for 1K\n will be placed in the position of the old region 3, whereas before we\n appended it to the still active region 1, placing it at the location\n of the old region 2. Before we had 1 free region of 2K, now we only\n get two free regions of 1K -\u003e fragmentation.\n\nThe patch addresses thes issues by introducing yet another cache descriptor\ncached_hole_size that contains the largest known hole size below the\ncurrent free_area_cache. If a new request comes in the size is compared\nagainst the cached_hole_size and if the request can be filled with a hole\nbelow free_area_cache the search is started from the base instead.\n\nThe results look promising: Whereas 2.6.12-rc4 fragments quickly and my\n(earlier posted) leakme.c test program terminates after 50000+ iterations\nwith 96 distinct and fragmented maps in /proc/self/maps it performs nicely\n(as expected) with thread creation, Ingo\u0027s test_str02 with 20000 threads\nrequires 0.7s system time.\n\nTaking out Ingo\u0027s patch (un-patch available per request) by basically\ndeleting all mentions of free_area_cache from the kernel and starting the\nsearch for new memory always at the respective bases we observe: leakme\nterminates successfully with 11 distinctive hardly fragmented areas in\n/proc/self/maps but thread creating is gringdingly slow: 30+s(!) system\ntime for Ingo\u0027s test_str02 with 20000 threads.\n\nNow - drumroll ;-) the appended patch works fine with leakme: it ends with\nonly 7 distinct areas in /proc/self/maps and also thread creation seems\nsufficiently fast with 0.71s for 20000 threads.\n\nSigned-off-by: Wolfgang Wander \u003cwwc@rentec.com\u003e\nCredit-to: \"Richard Purdie\" \u003crpurdie@rpsys.net\u003e\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e (partly)\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "88314ee73fd75eb32abdcb3119cd303c116d4500", "tree": "913c23ad89ec778d62eb517487dc6ab545d869c5", "parents": [ "7c963ad1d113790a8c723a178988b675868f3abe" ], "author": { "name": "David S.
