This may be improved by using\nhighmem for saving the contents of saveable highmem pages.\n\nNamely, during the suspend phase of the suspend-resume cycle we try to\nallocate as many free highmem pages as there are saveable highmem pages.\nIf there are not enough highmem image pages to store the contents of all of\nthe saveable highmem pages, some of them will be stored in the \"normal\"\nmemory. Next, we allocate as many free \"normal\" pages as needed to store\nthe (remaining) image data. We use a memory bitmap to mark the allocated\nfree pages (ie. highmem as well as \"normal\" image pages).\n\nNow, we use another memory bitmap to mark all of the saveable pages\n(highmem as well as \"normal\") and the contents of the saveable pages are\ncopied into the image pages. Then, the second bitmap is used to save the\npfns corresponding to the saveable pages and the first one is used to save\ntheir data.\n\nDuring the resume phase the pfns of the pages that were saveable during the\nsuspend are loaded from the image and used to mark the \"unsafe\" page\nframes. Next, we try to allocate as many free highmem page frames as to\nload all of the image data that had been in the highmem before the suspend\nand we allocate so many free \"normal\" page frames that the total number of\nallocated free pages (highmem and \"normal\") is equal to the size of the\nimage. While doing this we have to make sure that there will be some extra\nfree \"normal\" and \"safe\" page frames for two lists of PBEs constructed\nlater.\n\nNow, the image data are loaded, if possible, into their \"original\" page\nframes. The image data that cannot be written into their \"original\" page\nframes are loaded into \"safe\" page frames and their \"original\" kernel\nvirtual addresses, as well as the addresses of the \"safe\" pages containing\ntheir copies, are stored in one of two lists of PBEs.\n\nOne list of PBEs is for the copies of \"normal\" suspend pages (ie. \"normal\"\npages that were saveable during the suspend) and it is used in the same way\nas previously (ie. by the architecture-dependent parts of swsusp). The\nother list of PBEs is for the copies of highmem suspend pages.

From the swsusp\u0027s point of view (1) is not a problem,\n because it is already taken care of by the swap-handling code, but (2) has\n to be taken into consideration.\n\nIn principle the location of a swap file\u0027s header may be determined with the\nhelp of appropriate filesystem driver. Unfortunately, however, it requires\nthe filesystem holding the swap file to be mounted, and if this filesystem is\njournaled, it cannot be mounted during a resume from disk. For this reason we\nneed some other means by which swap areas can be identified.\n\nFor example, to identify a swap area we can use the partition that holds the\narea and the offset from the beginning of this partition at which the swap\nheader is located.\n\nThe following patch allows swsusp to identify swap areas this way. It changes\nswap_type_of() so that it takes an additional argument representing an offset\nof the swap header within the partition represented by its first argument.\n\nSigned-off-by: Rafael J.

The proc interface\nto sysctl does not have that problem, as names are not densely allocated.\n\nBy not terminating a sysctl table until I have neither a ctl_name nor a\nprocname, it becomes simple to add sysctl entries that don\u0027t show up in the\nbinary sysctl interface.

Adding 0 is without effect and the signal delivery stops.\n\nClamp the division result to minimum 1 to avoid this.\n\nProblem was reported by Seongbae Park \u003cspark@google.com\u003e, who provided\nalso an inital patch.\n\nRoland sayeth:\n\n I have had some more time to think about the problem, and to reproduce it\n using Toyo\u0027s test case. For the record, if my understanding of the problem\n is correct, this happens only in one very particular case. First, the\n expiry time has to be so soon that in cputime_t units (usually 1s/HZ ticks)\n it\u0027s \u003c nthreads so the division yields zero. Second, it only affects each\n thread that is so new that its CPU time accumulation is zero so now+0 is\n still zero and -\u003eit_*_expires winds up staying zero. For the VIRT and PROF\n clocks when cputime_t is tick granularity (or the SCHED clock on\n configurations where sched_clock\u0027s value only advances on clock ticks), this\n is not hard to arrange with new threads starting up and blocking before they\n accumulate a whole tick of CPU time. That\u0027s what happens in Toyo\u0027s test\n case.\n\n Note that in general it is fine for that division to round down to zero,\n and set each thread\u0027s expiry time to its \"now\" time. The problem only\n arises with thread\u0027s whose \"now\" value is still zero, so that now+0 winds up\n 0 and is interpreted as \"not set\" instead of \"\u003e\u003d now\". So it would be a\n sufficient and more precise fix to just use max(ticks, 1) inside the loop\n when setting each it_*_expires value.\n\n But, it does no harm to round the division up to one and always advance\n every thread\u0027s expiry time. If the thread didn\u0027t already fire timers for\n the expiry time of \"now\", there is no expectation that it will do so before\n the next tick anyway. So I followed Thomas\u0027s patch in lifting the max out\n of the loops.\n\n This patch also covers the reload cases, which are harder to write a test\n for (and I didn\u0027t try). I\u0027ve tested it with Toyo\u0027s case and it fixes that.\n\n[toyoa@mvista.com: fix: min_t -\u003e max_t]\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: Daniel Walker \u003cdwalker@mvista.com\u003e\nCc: Toyo Abe \u003ctoyoa@mvista.com\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: Seongbae Park \u003cspark@google.com\u003e\nCc: Peter Mattis \u003cpmattis@google.com\u003e\nCc: Rohit Seth \u003crohitseth@google.com\u003e\nCc: Martin Bligh \u003cmbligh@google.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3f4a0b917ce72ef47e438d354c433eb645218e87", "tree": "82695f890785cfe1bd14303ce04453a16bd99c01", "parents": [ "b9f5d8040b470e4f74e3266ece2969ef06d0f8aa" ], "author": { "name": "john stultz", "email": "johnstul@us.ibm.com", "time": "Tue Oct 17 00:09:32 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Oct 17 08:18:42 2006 -0700" }, "message": "[PATCH] i386 Time: Avoid PIT SMP lockups\n\nAvoid possible PIT livelock issues seen on SMP systems (and reported by\nAndi), by not allowing it as a clocksource on SMP boxes.\n\nHowever, since the PIT may no longer be present, we have to properly handle\nthe cases where SMP systems have TSC skew and fall back from the TSC.\nSince the PIT isn\u0027t there, it would \"fall back\" to the TSC again.
