      "message": "swsusp: introduce restore platform operations\n\nAt least on some machines it is necessary to prepare the ACPI firmware for the\nrestoration of the system memory state from the hibernation image if the\n\"platform\" mode of hibernation has been used.  Namely, in that cases we need\nto disable the GPEs before replacing the \"boot\" kernel with the \"frozen\"\nkernel (cf.  http://bugzilla.kernel.org/show_bug.cgi?id\u003d7887).  After the\nrestore they will be re-enabled by hibernation_ops-\u003efinish(), but if the\nrestore fails, they have to be re-enabled by the restore code explicitly.\n\nFor this purpose we can introduce two additional hibernation operations,\ncalled pre_restore() and restore_cleanup() and call them from the restore code\npath.  Still, they should be called if the \"platform\" mode of hibernation has\nbeen used, so we need to pass the information about the hibernation mode from\nthe \"frozen\" kernel to the \"boot\" kernel in the image header.\n\nApparently, we can\u0027t drop the disabling of GPEs before the restore because of\nBug #7887 .   We also can\u0027t do it unconditionally, because the GPEs wouldn\u0027t\nhave been enabled after a successful restore if the suspend had been done in\nthe \u0027shutdown\u0027 or \u0027reboot\u0027 mode.\n\nIn principle we could (and probably should) unconditionally disable the GPEs\nbefore each snapshot creation *and* before the restore, but then we\u0027d have to\nunconditionally enable them after the snapshot creation as well as after the\nrestore (or restore failure)   Still, for this purpose we\u0027d need to modify\nacpi_enter_sleep_state_prep() and acpi_leave_sleep_state() and we\u0027d have to\nintroduce some mechanism synchronizing the disablind/enabling of the GPEs with\nthe device drivers\u0027 .suspend()/.resume() routines and with\ndisable_/enable_nonboot_cpus().   However, this would have affected the\nsuspend (ie.  s2ram) code as well as the hibernation, which I\u0027d like to avoid\nin this patch series.\n\nSigned-off-by: Rafael J.

Also, the memory needed to store the bitmaps is allocated\nwhen necessary (ie.  before the suspend) and freed after the resume which is\nmore reasonable.\n\nThe patch is designed to minimize the amount of changes and there are some\nnice simplifications and optimizations possible on top of it.  I am going to\nimplement them separately in the future.\n\nSigned-off-by: Rafael J.

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.  The pages\nin this list are restored (in a reversible way) right before the\narch-dependent code is called.\n\nSigned-off-by: Rafael J.

      "message": "[PATCH] swsusp: use partition device and offset to identify swap areas\n\nThe Linux kernel handles swap files almost in the same way as it handles swap\npartitions and there are only two differences between these two types of swap\nareas:\n\n(1) swap files need not be contiguous,\n\n(2) the header of a swap file is not in the first block of the partition\n    that holds it.  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.

      "message": "[PATCH] swsusp: userland interface\n\nThis patch introduces a user space interface for swsusp.\n\nThe interface is based on a special character device, called the snapshot\ndevice, that allows user space processes to perform suspend and resume-related\noperations with the help of some ioctls and the read()/write() functions.\n Additionally it allows these processes to allocate free swap pages from a\nselected swap partition, called the resume partition, so that they know which\nsectors of the resume partition are available to them.\n\nThe interface uses the same low-level system memory snapshot-handling\nfunctions that are used by the built-it swap-writing/reading code of swsusp.\n\nThe interface documentation is included in the patch.\n\nThe patch assumes that the major and minor numbers of the snapshot device will\nbe 10 (ie.  misc device) and 231, the registration of which has already been\nrequested.\n\nSigned-off-by: Rafael J.
