There are more details in the log entry for patch\n01/23 and in the header file comments inside that patch. Most of these\nchanges move code around with little or no change, and they should not\nbreak anything or change any behavior.\n\nThis sets a new standard for uniform arch support to enable clean\narch-independent implementations of new debugging and tracing stuff,\ndenoted by CONFIG_HAVE_ARCH_TRACEHOOK. Patch 20/23 adds that symbol to\narch/Kconfig, with comments listing everything an arch has to do before\nsetting \"select HAVE_ARCH_TRACEHOOK\". These are elaborted a bit at:\n\n\thttp://sourceware.org/systemtap/wiki/utrace/arch/HowTo\n\nThe new inlines that arch code must define or call have detailed kerneldoc\ncomments in the generic header files that say what is required.\n\nNo arch is obligated to do any work, and no arch\u0027s build should be broken\nby these changes. There are several steps that each arch should take so\nit can set HAVE_ARCH_TRACEHOOK. Most of these are simple. Providing this\nsupport will let new things people add for doing debugging and tracing of\nuser-level threads \"just work\" for your arch in the future. For an arch\nthat does not provide HAVE_ARCH_TRACEHOOK, some new options for such\nfeatures will not be available for config.\n\nI have done some arch work and will submit this to the arch maintainers\nafter the generic tracehook series settles in. For now, that work is\navailable in my GIT repositories, and in patch and mbox-of-patches form at\nhttp://people.redhat.com/roland/utrace/2.6-current/\n\nThis paves the way for my \"utrace\" work, to be submitted later. But it is\nnot innately tied to that. I hope that the tracehook series can go in\nsoon regardless of what eventually does or doesn\u0027t go on top of it. For\nanyone implementing any kind of new tracing/debugging plan, or just\nunderstanding all the context of the existing ptrace implementation,\nhaving tracehook.h makes things much easier to find and understand.\n\nThis patch:\n\nThis adds the new kernel-internal header file \u003clinux/tracehook.h\u003e. This\nis not yet used at all. The comments in the header introduce what the\nfollowing series of patches is about.\n\nThe aim is to formalize and consolidate all the places that the core\nkernel code and the arch code now ties into the ptrace implementation.\n\nThese patches mostly don\u0027t cause any functional change. They just move\nthe details of ptrace logic out of core code into tracehook.h inlines,\nwhere they are mostly compiled away to the same as before. All that\nchanges is that everything is thoroughly documented and any future\nreworking of ptrace, or addition of something new, would not have to touch\ncore code all over, just change the tracehook.h inlines.\n\nThe new linux/ptrace.h inlines are used by the following patches in the\nnew tracehook_*() inlines. Using these helpers for the ptrace event stops\nmakes it simple to change or disable the old ptrace implementation of\nthese stops conditionally later.\n\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nReviewed-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "267e2a9c71b8e088ac307f9549f71468e86e26c1", "tree": "a2fc7be0ee2d712841b4564abf4e63d814642ec3", "parents": [ "99fcd77d15357e8ba51005c25cc750b9c28b2688" ], "author": { "name": "Arjan van de Ven", "email": "arjan@linux.intel.com", "time": "Fri Jul 25 19:45:41 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 26 12:00:08 2008 -0700" }, "message": "Use WARN() in fs/proc/\n\nUse WARN() instead of a printk+WARN_ON() pair; this way the message\nbecomes part of the warning section for better reporting/collection.\nThis way, the entire if() {} section can collapse into the WARN() as well.\n\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nAcked-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "99fcd77d15357e8ba51005c25cc750b9c28b2688", "tree": "403293819dc7bcd854c50d8c486a1fdbbf9711a2", "parents": [ "5c752ad9f35910ff1912b3f3ae82878178ddc432" ], "author": { "name": "Arjan van de Ven", "email": "arjan@linux.intel.com", "time": "Fri Jul 25 19:45:41 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 26 12:00:07 2008 -0700" }, "message": "Use WARN() in fs/sysfs\n\nUse WARN() instead of a printk+WARN_ON() pair; this way the message becomes\npart of the warning section for better reporting/collection.

Page table existence is guaranteed by\nturning interrupts off (combined with the fact that we\u0027re always looking\nup the current mm, means we can do the lockless page table walk within the\nconstraints of the TLB shootdown design). Basically we can do this\nlockless pagetable walk in a similar manner to the way the CPU\u0027s pagetable\nwalker does not have to take any locks to find present ptes.\n\nThis patch (combined with the subsequent ones to convert direct IO to use\nit) was found to give about 10% performance improvement on a 2 socket 8\ncore Intel Xeon system running an OLTP workload on DB2 v9.5\n\n \"To test the effects of the patch, an OLTP workload was run on an IBM\n x3850 M2 server with 2 processors (quad-core Intel Xeon processors at\n 2.93 GHz) using IBM DB2 v9.5 running Linux 2.6.24rc7 kernel. Comparing\n runs with and without the patch resulted in an overall performance\n benefit of ~9.8%. Correspondingly, oprofiles showed that samples from\n __up_read and __down_read routines that is seen during thread contention\n for system resources was reduced from 2.8% down to .05%. Monitoring the\n /proc/vmstat output from the patched run showed that the counter for\n fast_gup contained a very high number while the fast_gup_slow value was\n zero.\"\n\n(fast_gup is the old name for get_user_pages_fast, fast_gup_slow is a\ncounter we had for the number of times the slowpath was invoked).\n\nThe main reason for the improvement is that DB2 has multiple threads each\nissuing direct-IO. Direct-IO uses get_user_pages, and thus the threads\ncontend the mmap_sem cacheline, and can also contend on page table locks.\n\nI would anticipate larger performance gains on larger systems, however I\nthink DB2 uses an adaptive mix of threads and processes, so it could be\nthat thread contention remains pretty constant as machine size increases.\nIn which case, we stuck with \"only\" a 10% gain.\n\nThe downside of using get_user_pages_fast is that if there is not a pte\nwith the correct permissions for the access, we end up falling back to\nget_user_pages and so the get_user_pages_fast is a bit of extra work.\nHowever this should not be the common case in most performance critical\ncode.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: Kconfig fix]\n[akpm@linux-foundation.org: Makefile fix/cleanup]\n[akpm@linux-foundation.org: warning fix]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nCc: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Zach Brown \u003czach.brown@oracle.com\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nReviewed-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "21cc199baa815d7b3f1ace4be20b9558cbddc00f", "tree": "eb4f3fa42a83613e2fe586b2555a811740952dce", "parents": [ "a0a8f5364a5ad248aec6cb705e0092ff563edc2f" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Fri Jul 25 19:45:22 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 26 12:00:05 2008 -0700" }, "message": "mm: introduce get_user_pages_fast\n\nIntroduce a new get_user_pages_fast mm API, which is basically a\nget_user_pages with a less general API (but still tends to be suited to\nthe common case):\n\n- task and mm are always current and current-\u003emm\n- force is always 0\n- pages is always non-NULL\n- don\u0027t pass back vmas\n\nThis restricted API can be implemented in a much more scalable way on many\narchitectures when the ptes are present, by walking the page tables\nlocklessly (no mmap_sem or page table locks).

You can kexec a\n hibernating kernel, save the memory image of original system and shutdown\n the system. When resuming, you restore the memory image of original system\n via ordinary kexec load then jump back.\n\n- Kernel/system debug through making system snapshot.

Compile and install patched kernel with following options selected:\n\nCONFIG_X86_32\u003dy\nCONFIG_RELOCATABLE\u003dy\nCONFIG_KEXEC\u003dy\nCONFIG_CRASH_DUMP\u003dy\nCONFIG_PM\u003dy\nCONFIG_HIBERNATION\u003dy\nCONFIG_KEXEC_JUMP\u003dy\n\n2. Build an initramfs image contains kexec-tool and makedumpfile, or\n download the pre-built initramfs image, called rootfs.gz in\n following text.\n\n3. Prepare a partition to save memory image of original kernel, called\n hibernating partition in following text.\n\n4. Boot kernel compiled in step 1 (kernel A).\n\n5. In the kernel A, load kernel compiled in step 1 (kernel B) with\n /sbin/kexec. The shell command line can be as follow:\n\n /sbin/kexec --load-preserve-context /boot/bzImage --mem-min\u003d0x100000\n --mem-max\u003d0xffffff --initrd\u003drootfs.gz\n\n6. Boot the kernel B with following shell command line:\n\n /sbin/kexec -e\n\n7. The kernel B will boot as normal kexec. In kernel B the memory\n image of kernel A can be saved into hibernating partition as\n follow:\n\n jump_back_entry\u003d`cat /proc/cmdline | tr \u0027 \u0027 \u0027\\n\u0027 | grep kexec_jump_back_entry | cut -d \u0027\u003d\u0027`\n echo $jump_back_entry \u003e kexec_jump_back_entry\n cp /proc/vmcore dump.elf\n\n Then you can shutdown the machine as normal.\n\n8. Boot kernel compiled in step 1 (kernel C). Use the rootfs.gz as\n root file system.\n\n9. In kernel C, load the memory image of kernel A as follow:\n\n /sbin/kexec -l --args-none --entry\u003d`cat kexec_jump_back_entry` dump.elf\n\n10. Jump back to the kernel A as follow:\n\n /sbin/kexec -e\n\n Then, kernel A is resumed.\n\nImplementation point:\n\nTo support jumping between two kernels, before jumping to (executing)\nthe new kernel and jumping back to the original kernel, the devices\nare put into quiescent state, and the state of devices and CPU is\nsaved. After jumping back from kexeced kernel and jumping to the new\nkernel, the state of devices and CPU are restored accordingly. The\ndevices/CPU state save/restore code of software suspend is called to\nimplement corresponding function.\n\nKnown issues:\n\n- Because the segment number supported by sys_kexec_load is limited,\n hibernation image with many segments may not be load. This is\n planned to be eliminated by adding a new flag to sys_kexec_load to\n make a image can be loaded with multiple sys_kexec_load invoking.\n\nNow, only the i386 architecture is supported.\n\nSigned-off-by: Huang Ying \u003cying.huang@intel.com\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: \"Eric W.

So I\nCC\u0027ed this to KVM camp. Comments are appreciated.\n\nA pointer to dma_mapping_ops to struct dev_archdata is added. If the\npointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it\u0027s\nNULL, the system-wide dma_ops pointer is used as before.\n\nIf it\u0027s useful for KVM people, I plan to implement a mechanism to register\na hook called when a new pci (or dma capable) device is created (it works\nwith hot plugging). It enables IOMMUs to set up an appropriate\ndma_mapping_ops per device.\n\nThe major obstacle is that dma_mapping_error doesn\u0027t take a pointer to the\ndevice unlike other DMA operations. So x86 can\u0027t have dma_mapping_ops per\ndevice. Note all the POWER IOMMUs use the same dma_mapping_error function\nso this is not a problem for POWER but x86 IOMMUs use different\ndma_mapping_error functions.\n\nThe first patch adds the device argument to dma_mapping_error. The patch\nis trivial but large since it touches lots of drivers and dma-mapping.h in\nall the architecture.\n\nThis patch:\n\ndma_mapping_error() doesn\u0027t take a pointer to the device unlike other DMA\noperations. So we can\u0027t have dma_mapping_ops per device.\n\nNote that POWER already has dma_mapping_ops per device but all the POWER\nIOMMUs use the same dma_mapping_error function. x86 IOMMUs use device\nargument.\n\n[akpm@linux-foundation.org: fix sge]\n[akpm@linux-foundation.org: fix svc_rdma]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix bnx2x]\n[akpm@linux-foundation.org: fix s2io]\n[akpm@linux-foundation.org: fix pasemi_mac]\n[akpm@linux-foundation.org: fix sdhci]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix sparc]\n[akpm@linux-foundation.org: fix ibmvscsi]\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Muli Ben-Yehuda \u003cmuli@il.ibm.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Avi Kivity \u003cavi@qumranet.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c485b465a031b6f9b9a51300e0ee1f86efc6db87", "tree": "41c198953a1b2519322b67df4a315b2233998f9b", "parents": [ "999ed65ad12e374d7445fbc13f5a1d146ae4b0da" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Jul 25 19:44:47 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 26 12:00:02 2008 -0700" }, "message": "pnp: fix the fcpnp_driver declaration to only exist if CONFIG_PNP\u003dy\n\nFix the fcpnp_driver declaration to only exist if CONFIG_PNP\u003dy as it\u0027s\nonly accessed in that case.\n\nThe PNP\u003dn variant was added by 30d55e71a81b1f5a8136f191dc9f4c21f18e77e6\n(\"hisax: depend on CONFIG_PNP, not __ISAPNP__\")\n\nFixes an unused variable warning.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nCc: Karsten Keil \u003ckkeil@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "999ed65ad12e374d7445fbc13f5a1d146ae4b0da", "tree": "68b2232e19c9db8aeafbd7125cdec9c37c6598e3", "parents": [ "00412be1d7bdf451653c7dafeb09f4f83398d756" ], "author": { "name": "Rene Herman", "email": "rene.herman@gmail.com", "time": "Fri Jul 25 19:44:47 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 26 12:00:02 2008 -0700" }, "message": "pnp: have quirk_system_pci_resources() include io resources\n\nquirk_system_pci_resources() disables a PnP mem resource that overlaps a\nPCI BAR so as to not keep the PCI driver from claiming the resource.
