Moreover, since memory allocations are\ngoing to be used for the hibernation memory shrinking, it will be even\nmore likely to happen during hibernation.\n\nTo prevent it from happening, introduce the oom_killer_disabled switch\nthat will cause __alloc_pages_internal() to fail in the situations in\nwhich the OOM killer would have been called and make the freezer set\nthis switch after tasks have been successfully frozen.\n\n[akpm@linux-foundation.org: be nicer to the namespace]\nSigned-off-by: Rafael J.

It provides a way to stop and resume execution of all tasks in\na cgroup by writing in the cgroup filesystem.\n\nThe freezer subsystem in the container filesystem defines a file named\nfreezer.state. Writing \"FROZEN\" to the state file will freeze all tasks\nin the cgroup. Subsequently writing \"RUNNING\" will unfreeze the tasks in\nthe cgroup. Reading will return the current state.\n\n* Examples of usage :\n\n # mkdir /containers/freezer\n # mount -t cgroup -ofreezer freezer /containers\n # mkdir /containers/0\n # echo $some_pid \u003e /containers/0/tasks\n\nto get status of the freezer subsystem :\n\n # cat /containers/0/freezer.state\n RUNNING\n\nto freeze all tasks in the container :\n\n # echo FROZEN \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n FREEZING\n # cat /containers/0/freezer.state\n FROZEN\n\nto unfreeze all tasks in the container :\n\n # echo RUNNING \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n RUNNING\n\nThis is the basic mechanism which should do the right thing for user space\ntask in a simple scenario.\n\nIt\u0027s important to note that freezing can be incomplete. In that case we\nreturn EBUSY. This means that some tasks in the cgroup are busy doing\nsomething that prevents us from completely freezing the cgroup at this\ntime. After EBUSY, the cgroup will remain partially frozen -- reflected\nby freezer.state reporting \"FREEZING\" when read. The state will remain\n\"FREEZING\" until one of these things happens:\n\n\t1) Userspace cancels the freezing operation by writing \"RUNNING\" to\n\t\tthe freezer.state file\n\t2) Userspace retries the freezing operation by writing \"FROZEN\" to\n\t\tthe freezer.state file (writing \"FREEZING\" is not legal\n\t\tand returns EIO)\n\t3) The tasks that blocked the cgroup from entering the \"FROZEN\"\n\t\tstate disappear from the cgroup\u0027s set of tasks.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: export thaw_process]\nSigned-off-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nAcked-by: Serge E.

The 2.6.28 code does not have this issue, but since the mcount\nrecording is not going to be in 27, this must be solved for the ftrace\ndaemon version.\n\nThe resume from suspend to ram would reboot because it was triple\nfaulting. Debugging further, I found that calling the mcount function\nitself was not an issue, but it would fault when it incremented\npreempt_count. preempt_count is on the tasks info structure that is on the\nlow memory address of the task\u0027s stack. For some reason, it could not\nwrite to it. Resuming out of suspend to ram does quite a lot of funny\ntricks to get to work, so it is not surprising at all that simply doing a\npreempt_disable() would cause a fault.\n\nThanks to Rafael for suggesting to add a \"while (1);\" to find the place in\nresuming that is causing the fault. I would place the loop somewhere in\nthe code, compile and reboot and see if it would either reboot (hit the\nfault) or simply hang (hit the loop). Doing this over and over again, I\nnarrowed it down that it was happening in enable_nonboot_cpus.\n\nAt this point, I found that it is easier to simply disable tracing around\nthe suspend code, instead of searching for the particular function that\ncan not handle doing a preempt_disable.\n\nThis patch disables the tracer as it suspends and reenables it on resume.\n\nI tested this patch on my Laptop, and it can resume fine with the patch.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nAcked-by: Rafael J.

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.
