Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "5a7aadfe2fcb0f69e2acc1fbefe22a096e792fc9", "tree": "dc1b649fc6aa05ecd25cab23e464894e660830d5", "parents": [ "4f598458ea4450f53e8ed929ee4e66b3404a7286" ], "author": { "name": "Matt Helsley", "email": "matthltc@us.ibm.com", "time": "Fri Mar 26 23:51:44 2010 +0100" }, "committer": { "name": "Rafael J.

Currently we test the cgroup freezer\nstate of the resuming tasks to see if the cgroup is FROZEN. If so\nthen we don\u0027t thaw the task. However, the FREEZING state also indicates\nthat the task should remain frozen.\n\nThis also avoids a problem pointed out by Oren Ladaan: the freezer state\ntransition from FREEZING to FROZEN is updated lazily when userspace reads\nor writes the freezer.state file in the cgroup filesystem. This means that\nresume will thaw tasks in cgroups which should be in the FROZEN state if\nthere is no read/write of the freezer.state file to trigger this\ntransition before suspend.\n\nNOTE: Another \"simple\" solution would be to always update the cgroup\nfreezer state during resume. However it\u0027s a bad choice for several reasons:\nUpdating the cgroup freezer state is somewhat expensive because it requires\nwalking all the tasks in the cgroup and checking if they are each frozen.\nWorse, this could easily make resume run in N^2 time where N is the number\nof tasks in the cgroup. Finally, updating the freezer state from this code\npath requires trickier locking because of the way locks must be ordered.\n\nInstead of updating the freezer state we rely on the fact that lazy\nupdates only manage the transition from FREEZING to FROZEN. We know that\na cgroup with the FREEZING state may actually be FROZEN so test for that\nstate too. This makes sense in the resume path even for partially-frozen\ncgroups -- those that really are FREEZING but not FROZEN.\n\nReported-by: Oren Ladaan \u003corenl@cs.columbia.edu\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Rafael J.

Unfortunately, this\nturns out to break ARM platforms that need to talk via I2C to power\ncontrol devices during the .prepare() callback.\n\nFor this reason introduce two new platform suspend callbacks,\n.prepare_late() and .wake(), that will be called just prior to\ndisabling non-boot CPUs and right after bringing them back on line,\nrespectively, and use them instead of .prepare() and .finish() for\nACPI suspend. Make the PM core execute the .prepare() and .finish()\nplatform suspend callbacks where they were executed previously (that\nis, right after calling the regular suspend methods provided by\ndevice drivers and right before executing their regular resume\nmethods, respectively).\n\nIt is not necessary to make analogous changes to the hibernation\ncode and data structures at the moment, because they are only used\nby ACPI platforms.\n\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.

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.
