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. You can make system\n snapshot, jump back, do some thing and make another system snapshot.\n\n- Cooperative multi-kernel/system. With kexec jump, you can switch between\n several kernels/systems quickly without boot process except the first time.\n This appears like swap a whole kernel/system out/in.\n\n- A general method to call program in physical mode (paging turning\n off). This can be used to invoke BIOS code under Linux.\n\nThe following user-space tools can be used with kexec jump:\n\n- kexec-tools needs to be patched to support kexec jump. The patches\n and the precompiled kexec can be download from the following URL:\n source: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-src_git_kh10.tar.bz2\n patches: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-patches_git_kh10.tar.bz2\n binary: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec_git_kh10\n\n- makedumpfile with patches are used as memory image saving tool, it\n can exclude free pages from original kernel memory image file. The\n patches and the precompiled makedumpfile can be download from the\n following URL:\n source: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile-src_cvs_kh10.tar.bz2\n patches: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile-patches_cvs_kh10.tar.bz2\n binary: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile_cvs_kh10\n\n- An initramfs image can be used as the root file system of kexeced\n kernel. An initramfs image built with \"BuildRoot\" can be downloaded\n from the following URL:\n initramfs image: http://khibernation.sourceforge.net/download/release_v10/initramfs/rootfs_cvs_kh10.gz\n All user space tools above are included in the initramfs image.\n\nUsage example of simple hibernation:\n\n1. 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.

This\nlead to very tedious failure mode where the tail of one elf note would\noverwrite the head of another if they ended up being alocated sequentially\nby kmalloc, which was often the case.\n\nIt seems to me that a far better approach is to caclculate the size that\nthe area needs to be. This patch does just that.\n\nIf a simpler stop-gap patch for ia64 to be squeezed into 2.6.21(.X) is\nneeded then this should be as easy as making MAX_NOTE_BYTES larger in\narch/asm-ia64/kexec.h. Perhaps 2048 would be a good choice. However, I\nthink that the approach in this patch is a much more robust idea.\n\nAcked-by: Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\nSigned-off-by: Simon Horman \u003chorms@verge.net.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6ee7e78e7c78d871409ad4df30551c9355be7d0e", "tree": "84deeea72d7234d0b5652483b11760f394ae1131", "parents": [ "7f3af60e5a444b287d740a84998a8f480645dadf", "52fd91088bcbaea5ab441d09d39c21eb684e54ea" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 15:39:22 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 15:39:22 2006 -0800" }, "message": "Merge branch \u0027release\u0027 of master.kernel.org:/pub/scm/linux/kernel/git/aegl/linux-2.6\n\n* \u0027release\u0027 of master.kernel.org:/pub/scm/linux/kernel/git/aegl/linux-2.6:\n [IA64] replace kmalloc+memset with kzalloc\n [IA64] resolve name clash by renaming is_available_memory()\n [IA64] Need export for csum_ipv6_magic\n [IA64] Fix DISCONTIGMEM without VIRTUAL_MEM_MAP\n [PATCH] Add support for type argument in PAL_GET_PSTATE\n [IA64] tidy up return value of ip_fast_csum\n [IA64] implement csum_ipv6_magic for ia64.\n [IA64] More Itanium PAL spec updates\n [IA64] Update processor_info features\n [IA64] Add se bit to Processor State Parameter structure\n [IA64] Add dp bit to cache and bus check structs\n [IA64] SN: Correctly update smp_affinty mask\n [IA64] sparse cleanups\n [IA64] IA64 Kexec/kdump\n" }, { "commit": "a79561134f38de12dce14ed72138f38e55ef53fc", "tree": "abe109dbe85e5b0085ba9b9a7eed7cc623d67eec", "parents": [ "620034c84d1d939717bdfbe02c51a3fee43541c3" ], "author": { "name": "Zou Nan hai", "email": "nanhai.zou@intel.com", "time": "Thu Dec 07 09:51:35 2006 -0800" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Thu Dec 07 09:51:35 2006 -0800" }, "message": "[IA64] IA64 Kexec/kdump\n\nChanges and updates.\n\n1.

When die() finds the CPU\u0027s bit set\nin cpu_in_sr crash_kexec() is called to initiate a crash dump. The first\nCPU to enter crash_kexec() is called the \"crashing CPU\". All other CPUs\nare \"secondary CPUs\". The secondary CPU\u0027s pass through to\ncrash_kexec_secondary() and sleep. The crashing CPU waits for all CPUs\nto enter via soft-reset then boots the kdump kernel (see\ncrash_soft_reset_check())\n\nWhen the system crashes due to a panic or exception, crash_kexec() is\ncalled by panic() or die(). The crashing CPU sends an IPI to all other\nCPUs to notify them of the pending shutdown. If a CPU is in a deadlock\nor hung state with interrupts disabled, the IPI will not be delivered.\nThe result being, that the kdump kernel is not booted. This problem is\nsolved with the use of a firmware generated soft-reset. After the\ncrashing_cpu has issued the IPI, it waits for 10 sec for all CPUs to\nenter crash_ipi_callback(). A CPU signifies its entry to\ncrash_ipi_callback() by setting its corresponding bit in the\ncpus_in_crash bit array. After 10 sec, if one or more CPUs have not set\ntheir bit in cpus_in_crash we assume that the CPU(s) is deadlocked. The\noperator is then prompted to generate a soft-reset to break the\ndeadlock. Each CPU enters the soft reset handler as described above.\n\nTwo conditions must be handled at this point:\n1) The system crashed because the operator generated a soft-reset. See\n2) The system had crashed before the soft-reset was generated ( in the\ncase of a Panic or oops).\n\nThe first CPU to enter crash_kexec() uses the state of the kexec_lock to\ndetermine this state. If kexec_lock is already held then condition 2 is\ntrue and crash_kexec_secondary() is called, else; this CPU is flagged as\nthe crashing CPU, the kexec_lock is acquired and crash_kexec() proceeds\nas described above.\n\nEach additional CPUs responding to the soft-reset will pass through\ncrash_kexec() to kexec_secondary(). All secondary CPUs call\ncrash_ipi_callback() readying them self\u0027s for the shutdown. When ready\nthey clear their bit in cpus_in_sr. The crashing CPU waits in\nkexec_secondary() until all other CPUs have cleared their bits in\ncpus_in_sr. The kexec kernel boot is then started.\n\nSigned-off-by: Haren Myneni \u003charen@us.ibm.com\u003e\nSigned-off-by: David Wilder \u003cdwilder@us.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "c330dda908b5a46469a997eea90b66f2f9f02b34", "tree": "aad52aa4e127c366ca185c2122650d7dbb3437a0", "parents": [ "24bbb1faf3f0420eb252dd0fdc1e477b1d4d73bd" ], "author": { "name": "Jeff Moyer", "email": "jmoyer@redhat.com", "time": "Fri Jun 23 02:05:07 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 23 07:43:02 2006 -0700" }, "message": "[PATCH] Add a sysfs file to determine if a kexec kernel is loaded\n\nCreate two files in /sys/kernel, kexec_loaded and kexec_crash_loaded.

But I don\u0027t think it\u0027s worth being user-configurable: for good\ntesting of both split and unsplit configs, split now at 4 cpus, and perhaps\nchange that to 8 later.\n\nThere is a benefit even for singly threaded processes: kswapd can be attacking\none part of the mm while another part is busy faulting.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9796fdd829da626374458e8706daedcc0e432ddd", "tree": "a0b4af7f45267cdcdfb677c2167906c6ef981b76", "parents": [ "55016f10e31bb15b85d8c500f979dfdceb37d548" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri Oct 21 03:22:03 2005 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Oct 28 08:16:49 2005 -0700" }, "message": "[PATCH] gfp_t: kernel/*\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "314b6a4d80a7a5217c86ffdca926b6f406da0e0e", "tree": "f2a1b6a94511fb449ff35c7a3f6b1dc0f548335e", "parents": [ "97afa0a25afb43a82954662773a9d48d61b2996a" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Jun 27 22:29:33 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Tue Jun 28 14:53:40 2005 -0700" }, "message": "[PATCH] kexec: fix sparse warnings\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Eric Biederman \u003cebiederm@xmission.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "72414d3f1d22fc3e311b162fca95c430048d38ce", "tree": "46850947c1602357dd3c51d8d6ebaa5805507f9f", "parents": [ "4f339ecb30c759f94a29992d4635d9194132b6cf" ], "author": { "name": "Maneesh Soni", "email": "maneesh@in.ibm.com", "time": "Sat Jun 25 14:58:28 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Jun 25 16:24:55 2005 -0700" }, "message": "[PATCH] kexec code cleanup\n\no Following patch provides purely cosmetic changes and corrects CodingStyle\n guide lines related certain issues like below in kexec related files\n\n o braces for one line \"if\" statements, \"for\" loops,\n o more than 80 column wide lines,\n o No space after \"while\", \"for\" and \"switch\" key words\n\no Changes:\n o take-2: Removed the extra tab before \"case\" key words.\n o take-3: Put operator at the end of line and space before \"*/\"\n\nSigned-off-by: Maneesh Soni \u003cmaneesh@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "6e274d144302068a00794ec22e73520c0615cb6f", "tree": "f7ea59ea47d3c5676fbac8d39e8deaa1f94146ae", "parents": [ "86b1ae38c0a62409dc862a28e3f08920f55f944b" ], "author": { "name": "Alexander Nyberg", "email": "alexn@telia.com", "time": "Sat Jun 25 14:58:26 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Jun 25 16:24:54 2005 -0700" }, "message": "[PATCH] kdump: Use real pt_regs from exception\n\nMakes kexec_crashdump() take a pt_regs * as an argument.
