Unfortunately, it\nbroke the at91 platform which assumed that pm_ops-\u003eprepare() would be called\nbefore suspending devices.\n\nat91 used pm_ops-\u003eprepare() to get notified of the target system sleep state,\nso that it could use this information while suspending devices. However, with\nthe current suspend code ordering pm_ops-\u003eprepare() is called too late for\nthis purpose. Thus, at91 needs an additional method in \u0027struct pm_ops\u0027 that\nwill be used for notifying the platform of the target system sleep state.\nMoreover, in the future such a method will also be needed by ACPI.\n\nThis patch adds the .set_target() method to \u0027struct pm_ops\u0027 and makes the\nsuspend code call it, if implemented, before executing the device model\nper-device .suspend() calls. It also modifies the at91 code to use\npm_ops-\u003eset_target() instead of pm_ops-\u003eprepare().\n\nSigned-off-by: Rafael J.

Unfortunately there\nare two SMP-related problems with this approach. First, a task running on\nanother CPU may be updating its flags while the freezer attempts to set\nPF_FREEZE for it and this may leave the task\u0027s flags in an inconsistent\nstate. Second, there is a potential race between freeze_process() and\nrefrigerator() in which freeze_process() running on one CPU is reading a\ntask\u0027s PF_FREEZE flag while refrigerator() running on another CPU has just\nset PF_FROZEN for the same task and attempts to reset PF_FREEZE for it. If\nthe refrigerator wins the race, freeze_process() will state that PF_FREEZE\nhasn\u0027t been set for the task and will set it unnecessarily, so the task\nwill go to the refrigerator once again after it\u0027s been thawed.\n\nTo solve first of these problems we need to stop using PF_FREEZE to tell\ntasks that they should go to the refrigerator. Instead, we can introduce a\nspecial TIF_*** flag and use it for this purpose, since it is allowed to\nchange the other tasks\u0027 TIF_*** flags and there are special calls for it.\n\nTo avoid the freeze_process()-refrigerator() race we can make\nfreeze_process() to always check the task\u0027s PF_FROZEN flag after it\u0027s read\nits \"freeze\" flag. We should also make sure that refrigerator() will\nalways reset the task\u0027s \"freeze\" flag after it\u0027s set PF_FROZEN for it.\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).

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.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386.

For this\nreason the memory bitmap structure consists of several linked lists of objects\nthat contain pointers to memory pages with the actual bitmap data. Still, for\na typical system all of these lists fit in a single page, so it\u0027s reasonable\nto introduce an additional mechanism allowing us to allocate all of them\nefficiently without sacrificing the generality of the design. This is done\nwith the help of the chain_allocator structure and associated functions.\n\nWe need to use two memory bitmaps during the suspend phase of the\nsuspend-resume cycle. One of them is necessary for marking the saveable\npages, and the second is used to mark the pages in which to store the copies\nof them (aka image pages).\n\nFirst, the bitmaps are created and we allocate as many image pages as needed\n(the corresponding bits in the second bitmap are set as soon as the pages are\nallocated). Second, the bits corresponding to the saveable pages are set in\nthe first bitmap and the saveable pages are copied to the image pages.\nFinally, the first bitmap is used to save the kernel virtual addresses of the\nsaveable pages and the second one is used to save the contents of the image\npages.\n\nSigned-off-by: Rafael J.
