2006-04-19[PATCH] swsusp: prevent possible image corruption on resumeRafael J. Wysocki
The function free_pagedir() used by swsusp for freeing its internal data structures clears the PG_nosave and PG_nosave_free flags for each page being freed. However, during resume PG_nosave_free set means that the page in question is "unsafe" (ie. it will be overwritten in the process of restoring the saved system state from the image), so it should not be used for the image data. Therefore free_pagedir() should not clear PG_nosave_free if it's called during resume (otherwise "unsafe" pages freed by it may be used for storing the image data and the data may get corrupted later on).

Add the SNAPSHOT_S2RAM ioctl to the snapshot device. This ioctl allows a userland application to make the system (previously frozen with the SNAPSHOT_FREE ioctl) enter the S3 state without freezing processes and disabling nonboot CPUs for the second time.

2006-03-23[PATCH] swsusp: userland interfaceRafael J. Wysocki
This patch introduces a user space interface for swsusp. The interface is based on a special character device, called the snapshot device, that allows user space processes to perform suspend and resume-related operations with the help of some ioctls and the read()/write() functions.  Additionally it allows these processes to allocate free swap pages from a selected swap partition, called the resume partition, so that they know which sectors of the resume partition are available to them. The interface uses the same low-level system memory snapshot-handling functions that are used by the built-it swap-writing/reading code of swsusp. The interface documentation is included in the patch. The patch assumes that the major and minor numbers of the snapshot device will be 10 (ie. misc device) and 231, the registration of which has already been requested. Signed-off-by: Rafael J.

2006-03-23[PATCH] swsusp: low level interfaceRafael J. Wysocki
Introduce the low level interface that can be used for handling the snapshot of the system memory by the in-kernel swap-writing/reading code of swsusp and the userland interface code (to be introduced shortly). Also change the way in which swsusp records the allocated swap pages and, consequently, simplifies the in-kernel swap-writing/reading code (this is necessary for the userland interface too). To this end, it introduces two helper functions in mm/swapfile.c, so that the swsusp code does not refer directly to the swap internals. Signed-off-by: Rafael J.

2006-01-06[PATCH] swsusp: save image header firstRafael J. Wysocki
This makes the swsusp_info structure become the header of the image in the literal sense (ie. it is saved to the swap and read before any other image data with the help of the swsusp's swap map structure, so generally it is treated in the same way as the rest of the image). The main thing it does is to make swsusp_header contain the offset of the swap map used to track the image data pages rather than the offset of swsusp_info.  Simultaneously, swsusp_info becomes the first image page written to the swap. The other changes are generally consequences of the above with a few exceptions (there's some consolidation in the image reading part as a few functions turn into trivial wrappers around something else).

2006-01-06[PATCH] swsusp: fix enough_free_memRafael J. Wysocki
This patch fixes a problem with the function enough_free_mem() used by swsusp to verify if there is a sufficient number of memory pages available to it to create and save the suspend image. Namely, enough_free_mem() uses nr_free_pages() to obtain the number of free memory pages, which is incorrect, because this function returns the total number of free pages, including free highmem pages, and the highmem pages cannot be used by swsusp for storing the image data. The patch makes enough_free_mem() avoid counting the free highmem pages as available to swsusp. Signed-off-by: Rafael J.

2006-01-06[PATCH] swsusp: improve freeing of memoryRafael J. Wysocki

X Windows) is used. If needed, the old behavior (ie to free as much memory as possible during suspend) can be restored by unsetting FAST_FREE in power.h Signed-off-by: Rafael J.

2006-01-06[PATCH] swsusp: introduce the swap map structureRafael J. Wysocki
This patch introduces the swap map structure that can be used by swsusp for keeping tracks of data pages written to the swap.  The structure itself is described in a comment within the patch. The overall idea is to reduce the amount of metadata written to the swap and to write and read the image pages sequentially, in a file-alike way. This makes the swap-handling part of swsusp fairly independent of its snapshot-handling part and will hopefully allow us to completely separate these two parts in the future. This patch is needed to remove the suspend image size limit imposed by the limited size of the swsusp_info structure, which is essential for x86-64 systems with more than 512 MB of RAM.
