It is expected that /sbin/halt -p works exactly like\n/sbin/halt, when the kernel does not implement power off functionality.\n\nThe kernel can do a lot of work in the reboot notifiers and in\ndevice_shutdown before we even get to machine_power_off. Some of that\nshutdown is not safe if you are leaving the power on, and it definitely\ngets in the way of using sysrq or pressing ctrl-alt-del. Since the\nshutdown happens in generic code there is no way to fix this in\narchitecture specific code :(\n\nSome machines are kernel oopsing today because of this.\n\nThe simple solution is to turn LINUX_REBOOT_CMD_POWER_OFF into\nLINUX_REBOOT_CMD_HALT if power_off functionality is not implemented.\n\nThis has the unfortunate side effect of disabling the power off\nfunctionality on architectures that leave pm_power_off to null and still\nimplement something in machine_power_off. And it will break the build on\nsome architectures that don\u0027t have a pm_power_off variable at all.\n\nOn both counts I say tough.\n\nFor architectures like alpha that don\u0027t implement the pm_power_off variable\npm_power_off is declared in linux/pm.h and it is a generic part of our\npower management code, and all architectures should implement it.\n\nFor architectures like parisc that have a default power off method in\nmachine_power_off if pm_power_off is not implemented or fails. It is easy\nenough to set the pm_power_off variable. And nothing bad happens there,\nthe machines just stop powering off.\n\nThe current semantics are impossible without a flag at the top level so we\ncan avoid the problem code if a power off is not implemented. pm_power_off\nis as good a flag as any with the bonus that it works without modification\non at least x86, x86_64, powerpc, and ppc today.\n\nAndrew can you pick this up and put this in the mm tree. Kernels that\ndon\u0027t compile or don\u0027t power off seem saner than kernels that oops or\npanic. Until we get the arch specific patches for the problem\narchitectures this probably isn\u0027t smart to push into the stable kernel.\nUnfortunately I don\u0027t have the time at the moment to walk through every\narchitecture and make them work.

The kernel maintains\ninternal state for each mempolicy, tracking what nodes are used for the\nMPOL_INTERLEAVE, MPOL_BIND or MPOL_PREFERRED policies.\n\nWhen a tasks cpuset memory placement changes, whether because the cpuset\nchanged, or because the task was attached to a different cpuset, then the\ntasks mempolicies have to be rebound to the new cpuset placement, so as to\npreserve the cpuset-relative numbering of the nodes in that policy.\n\nAn earlier fix handled such mempolicy rebinding for mempolicies attached to a\ntask.\n\nThis fix rebinds mempolicies attached to vma\u0027s (address ranges in a tasks\naddress space.) Due to the need to hold the task-\u003emm-\u003emmap_sem semaphore while\nupdating vma\u0027s, the rebinding of vma mempolicies has to be done when the\ncpuset memory placement is changed, at which time mmap_sem can be safely\nacquired. The tasks mempolicy is rebound later, when the task next attempts\nto allocate memory and notices that its task-\u003ecpuset_mems_generation is\nout-of-date with its cpusets mems_generation.\n\nBecause walking the tasklist to find all tasks attached to a changing cpuset\nrequires holding tasklist_lock, a spinlock, one cannot update the vma\u0027s of the\naffected tasks while doing the tasklist scan. In general, one cannot acquire\na semaphore (which can sleep) while already holding a spinlock (such as\ntasklist_lock). So a list of mm references has to be built up during the\ntasklist scan, then the tasklist lock dropped, then for each mm, its mmap_sem\nacquired, and the vma\u0027s in that mm rebound.\n\nOnce the tasklist lock is dropped, affected tasks may fork new tasks, before\ntheir mm\u0027s are rebound. A kernel global \u0027cpuset_being_rebound\u0027 is set to\npoint to the cpuset being rebound (there can only be one; cpuset modifications\nare done under a global \u0027manage_sem\u0027 semaphore), and the mpol_copy code that\nis used to copy a tasks mempolicies during fork catches such forking tasks,\nand ensures their children are also rebound.\n\nWhen a task is moved to a different cpuset, it is easier, as there is only one\ntask involved. It\u0027s mm-\u003evma\u0027s are scanned, using the same\nmpol_rebind_policy() as used above.\n\nIt may happen that both the mpol_copy hook and the update done via the\ntasklist scan update the same mm twice. This is ok, as the mempolicies of\neach vma in an mm keep track of what mems_allowed they are relative to, and\nsafely no-op a second request to rebind to the same nodes.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "202f72d5d1b5c2c084f63ef996c736d208b447b5", "tree": "f50551f9588f9090fee17130614e17a2dd64c656", "parents": [ "74cb21553f4bf244185b9bec4c26e4e3169ad55e" ], "author": { "name": "Paul Jackson", "email": "pj@sgi.com", "time": "Sun Jan 08 01:01:57 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:13:44 2006 -0800" }, "message": "[PATCH] cpuset: number_of_cpusets optimization\n\nEasy little optimization hack to avoid actually having to call\ncpuset_zone_allowed() and check mems_allowed, in the main page allocation\nroutine, __alloc_pages().

A process may\nhave migrated to another node. Memory was allocated optimally for the prior\ncontext. sys_migrate_pages allows to shift the memory to the new node.\n\nsys_migrate_pages is also useful if the processes available memory nodes have\nchanged through cpuset operations to manually move the processes memory. Paul\nJackson is working on an automated mechanism that will allow an automatic\nmigration if the cpuset of a process is changed. However, a user may decide\nto manually control the migration.\n\nThis implementation is put into the policy layer since it uses concepts and\nfunctions that are also needed for mbind and friends. The patch also provides\na do_migrate_pages function that may be useful for cpusets to automatically\nmove memory. sys_migrate_pages does not modify policies in contrast to Ray\u0027s\nimplementation.\n\nThe current code here is based on the swap based page migration capability and\nthus is not able to preserve the physical layout relative to it containing\nnodeset (which may be a cpuset). When direct page migration becomes available\nthen the implementation needs to be changed to do a isomorphic move of pages\nbetween different nodesets.

If \"p\" is\nnot current, and the tgids are the same, we will add the process\nt-\u003esched_time twice into cpu-\u003esched and omit \"p\"\u0027s sched_time\nwhich is very very very wrong.\n\nposix-cpu-timers.c has a helper function, sched_ns(p) which takes care\nof this, so my fix is to use that here instead of this special tgid\ntest.\n\nThe fact that current can be one of the sub-threads of \"p\" points out\nthat we could make things a little bit more accurate, perhaps by using\nsched_ns() on every thread we process in these loops. It also points\nout that we don\u0027t use the most accurate value for threads in the group\nactively running other cpus (and this is mentioned in the comment).\n\nBut that is a future enhancement, and this fix here definitely makes\nsense.\n\nSigned-off-by: David S.
