* [PATCH] swsusp: make image size limit tunableRafael J. Wysocki2006-01-061-0/+20
| | | | | | | | | | | | | Make the suspend image size limit tunable via /sys/power/image_size. It is necessary for systems on which there is a limited amount of swap available for suspend. It can also be useful for optimizing performance of swsusp on systems with 1 GB of RAM or more. Signed-off-by: Rafael J.

* [PATCH] swsusp: improve freeing of memoryRafael J. Wysocki2006-01-061-27/+3
| | | | | | | | | | | | | | | This patch makes swsusp free only as much memory as needed to complete the suspend and not as much as possible.  In the most of cases this should speed up the suspend and make the system much more responsive after resume, especially if a GUI (eg. 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.

* [PATCH] swsusp: introduce the swap map structureRafael J. Wysocki2006-01-061-4/+4
| | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] swsusp: two simplificationsRafael J. Wysocki2005-10-301-6/+2
| | | | | | | | | | | The following patch simplifies the progress meter in disk.c:free_some_memory() and makes disk.c:pm_suspend_disk() call device_resume() explicitly in the suspend path.

* [PATCH] swsusp: rework memory freeing on resumeRafael J. Wysocki2005-10-301-7/+7
| | | | | | | | | | | | The following patch makes swsusp use the PG_nosave and PG_nosave_free flags to mark pages that should be freed in case of an error during resume. This allows us to simplify the code and to use swsusp_free() in all of the swsusp's resume error paths, which makes them actually work. Signed-off-by: Rafael J.

* [PATCH] suspend: cleanup calling of power off methods.Eric W. Biederman2005-09-221-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | In the lead up to 2.6.13 I fixed a large number of reboot problems by making the calling conventions consistent. Despite checking and double checking my work it appears I missed an obvious one. The S4 suspend code for PM_DISK_PLATFORM was also calling device_shutdown without setting system_state, and was not calling the appropriate reboot_notifier. This patch fixes the bug by replacing the call of device_suspend with kernel_poweroff_prepare. Various forms of this failure have been fixed and tracked for a while.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
