+A: Well, it can be done, load the drivers, then do echo into

+

+
+A: That's right.  It depends on your hardware, and it could be true even for
+suspend-to-RAM.  In fact, even with "-o sync" you can lose data if your

+Documentation for userland software suspend interface
+        (C) 2006 Rafael J. Wysocki <rjw@sisk.pl>
+
+First, the warnings at the beginning of swsusp.txt still apply.
+
+Second, you should read the FAQ in swsusp.txt _now_ if you have not
+done it already.
+
+Now, to use the userland interface for software suspend you need special
+utilities that will read/write the system memory snapshot from/to the
+kernel.  Such utilities are available, for example, from
+<http://www.sisk.pl/kernel/utilities/suspend>.  You may want to have
+a look at them if you are going to develop your own suspend/resume
+utilities.
+
+The interface consists of a character device providing the open(),
+release(), read(), and write() operations as well as several ioctl()
+commands defined in kernel/power/power.h.  The major and minor
+numbers of the device are, respectively, 10 and 231, and they can
+be read from /sys/class/misc/snapshot/dev.
+
+The device can be open either for reading or for writing.  If open for
+reading, it is considered to be in the suspend mode.  Otherwise it is
+assumed to be in the resume mode.  The device cannot be open for reading
+and writing.  It is also impossible to have the device open more than once
+at a time.
+
+The ioctl() commands recognized by the device are:
+
+SNAPSHOT_FREEZE - freeze user space processes (the current process is
+        not frozen); this is required for SNAPSHOT_ATOMIC_SNAPSHOT
+        and SNAPSHOT_ATOMIC_RESTORE to succeed
+
+SNAPSHOT_UNFREEZE - thaw user space processes frozen by SNAPSHOT_FREEZE
+
+SNAPSHOT_ATOMIC_SNAPSHOT - create a snapshot of the system memory; the
+        last argument of ioctl() should be a pointer to an int variable,
+        the value of which will indicate whether the call returned after
+        creating the snapshot (1) or after restoring the system memory state
+        from it (0) (after resume the system finds itself finishing the
+        SNAPSHOT_ATOMIC_SNAPSHOT ioctl() again); after the snapshot
+        has been created the read() operation can be used to transfer
+        it out of the kernel
+
+SNAPSHOT_ATOMIC_RESTORE - restore the system memory state from the
+        uploaded snapshot image; before calling it you should transfer
+        the system memory snapshot back to the kernel using the write()
+        operation; this call will not succeed if the snapshot
+        image is not available to the kernel
+
+SNAPSHOT_FREE - free memory allocated for the snapshot image
+
+SNAPSHOT_SET_IMAGE_SIZE - set the preferred maximum size of the image
+        (the kernel will do its best to ensure the image size will not exceed
+        this number, but if it turns out to be impossible, the kernel will
+        create the smallest image possible)
+
+SNAPSHOT_AVAIL_SWAP - return the amount of available swap in bytes (the last
+        argument should be a pointer to an unsigned int variable that will
+        contain the result if the call is successful).
+
+SNAPSHOT_GET_SWAP_PAGE - allocate a swap page from the resume partition
+        (the last argument should be a pointer to a loff_t variable that
+        will contain the swap page offset if the call is successful)
+
+SNAPSHOT_FREE_SWAP_PAGES - free all swap pages allocated with
+        SNAPSHOT_GET_SWAP_PAGE
+
+SNAPSHOT_SET_SWAP_FILE - set the resume partition (the last ioctl() argument
+        should specify the device's major and minor numbers in the old
+        two-byte format, as returned by the stat() function in the .st_rdev
+        member of the stat structure); it is recommended to always use this
+        call, because the code to set the resume partition could be removed from
+        future kernels
+
+The device's read() operation can be used to transfer the snapshot image from
+the kernel.  It has the following limitations:
+- you cannot read() more than one virtual memory page at a time
+- read()s accross page boundaries are impossible (ie. if ypu read() 1/2 of
+        a page in the previous call, you will only be able to read()
+        _at_ _most_ 1/2 of the page in the next call)
+
+The device's write() operation is used for uploading the system memory snapshot
+into the kernel.  It has the same limitations as the read() operation.
+
+The release() operation frees all memory allocated for the snapshot image
+and all swap pages allocated with SNAPSHOT_GET_SWAP_PAGE (if any).
+Thus it is not necessary to use either SNAPSHOT_FREE or
+SNAPSHOT_FREE_SWAP_PAGES before closing the device (in fact it will also
+unfreeze user space processes frozen by SNAPSHOT_UNFREEZE if they are
+still frozen when the device is being closed).
+
+Currently it is assumed that the userland utilities reading/writing the
+snapshot image from/to the kernel will use a swap parition, called the resume
+partition, as storage space.  However, this is not really required, as they
+can use, for example, a special (blank) suspend partition or a file on a partition
+that is unmounted before SNAPSHOT_ATOMIC_SNAPSHOT and mounted afterwards.
+
+These utilities SHOULD NOT make any assumptions regarding the ordering of
+data within the snapshot image, except for the image header that MAY be
+assumed to start with an swsusp_info structure, as specified in
+kernel/power/power.h.  This structure MAY be used by the userland utilities
+to obtain some information about the snapshot image, such as the size
+of the snapshot image, including the metadata and the header itself,
+contained in the .size member of swsusp_info.
+
+The snapshot image MUST be written to the kernel unaltered (ie. all of the image
+data, metadata and header MUST be written in _exactly_ the same amount, form
+and order in which they have been read).  Otherwise, the behavior of the
+resumed system may be totally unpredictable.
+
+While executing SNAPSHOT_ATOMIC_RESTORE the kernel checks if the
+structure of the snapshot image is consistent with the information stored
+in the image header.  If any inconsistencies are detected,
+SNAPSHOT_ATOMIC_RESTORE will not succeed.  Still, this is not a fool-proof
+mechanism and the userland utilities using the interface SHOULD use additional
+means, such as checksums, to ensure the integrity of the snapshot image.
+
+The suspending and resuming utilities MUST lock themselves in memory,
+preferrably using mlockall(), before calling SNAPSHOT_FREEZE.
+
+The suspending utility MUST check the value stored by SNAPSHOT_ATOMIC_SNAPSHOT
+in the memory location pointed to by the last argument of ioctl() and proceed
+in accordance with it:
+1.      If the value is 1 (ie. the system memory snapshot has just been
+        created and the system is ready for saving it):
+        (a)     The suspending utility MUST NOT close the snapshot device
+                _unless_ the whole suspend procedure is to be cancelled, in
+                which case, if the snapshot image has already been saved, the
+                suspending utility SHOULD destroy it, preferrably by zapping
+                its header.  If the suspend is not to be cancelled, the
+                system MUST be powered off or rebooted after the snapshot
+                image has been saved.
+        (b)     The suspending utility SHOULD NOT attempt to perform any
+                file system operations (including reads) on the file systems
+                that were mounted before SNAPSHOT_ATOMIC_SNAPSHOT has been
+                called.  However, it MAY mount a file system that was not
+                mounted at that time and perform some operations on it (eg.
+                use it for saving the image).
+2.      If the value is 0 (ie. the system state has just been restored from
+        the snapshot image), the suspending utility MUST close the snapshot
+        device.  Afterwards it will be treated as a regular userland process,
+        so it need not exit.
+
+The resuming utility SHOULD NOT attempt to mount any file systems that could
+be mounted before suspend and SHOULD NOT attempt to perform any operations
+involving such file systems.
+
+For details, please refer to the source code.

+ * to use this timer for something else.  We also use timer 4 for keeping

 /**
- *      Swap map-handling functions
- *
- *      The swap map is a data structure used for keeping track of each page
- *      written to the swap.  It consists of many swap_map_page structures
- *      that contain each an array of MAP_PAGE_SIZE swap entries.
- *      These structures are linked together with the help of either the
- *      .next (in memory) or the .next_swap (in swap) member.
+ *      The following functions are used for tracing the allocated
+ *      swap pages, so that they can be freed in case of an error.
  *
- *      The swap map is created during suspend.  At that time we need to keep
- *      it in memory, because we have to free all of the allocated swap
- *      entries if an error occurs.  The memory needed is preallocated
- *      so that we know in advance if there's enough of it.
- *
- *      The first swap_map_page structure is filled with the swap entries that
- *      correspond to the first MAP_PAGE_SIZE data pages written to swap and
- *      so on.  After the all of the data pages have been written, the order
- *      of the swap_map_page structures in the map is reversed so that they
- *      can be read from swap in the original order.  This causes the data
- *      pages to be loaded in exactly the same order in which they have been
- *      saved.
- *
- *      During resume we only need to use one swap_map_page structure
- *      at a time, which means that we only need to use two memory pages for
- *      reading the image - one for reading the swap_map_page structures
- *      and the second for reading the data pages from swap.
+ *      The functions operate on a linked bitmap structure defined
+ *      in power.h
