2006-09-26[PATCH] PM: make it possible to disable console suspendingRafael J. Wysocki
Change suspend_console() so that it waits for all consoles to flush the remaining messages and make it possible to switch the console suspending off with the help of a Kconfig option.

2006-09-25PM: add kconfig option for deprecated .../power/state filesDavid Brownell
Add a new PM_SYSFS_DEPRECATED config option to control whether or not the /sys/devices/.../power/state files are provided. This will make it easier to get rid of that mechanism when the time comes, and to verify that userspace tools work right without it.

2006-09-06[PATCH] prevent swsusp with PAEPavel Machek
PAE + swsusp results in hard-to-debug crash about 50% of time during resume. Cause is known, fix needs to be ported from x86-64 (but we can't make it to 2.6.18, and I'd like this to be worked around in 2.6.18).

Remove SWSUSP_ENCRYPT config option; it is no longer implemented. Signed-off-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Adrian Bunk <bunk@stusta.de>
2006-06-27[PATCH] pm_trace is dangerousAndrew Morton
CONFIG_PM_TRACES scrogs your RTC. Mark it as experimental, and defaulting to `off'. Also beef up the help message a bit. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-25Fix PM_TRACE dependency: works only on 32-bit x86 for nowLinus Torvalds
Not that x86-64 and other architecture support should be difficult to add (trivial fixups to the data format and add the proper linker script entry). Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-24Add some basic resume trace facilitiesLinus Torvalds
Considering that there isn't a lot of hw we can depend on during resume, this is about as good as it gets. This is x86-only for now, although the basic concept (and most of the code) will certainly work on almost any platform. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-04-01help text: SOFTWARE_SUSPEND doesn't need ACPIAdrian Bunk
The note that SOFTWARE_SUSPEND doesn't need APM is helpful, but nowadays the information that it doesn't need ACPI, too, is even more helpful. Signed-off-by: Adrian Bunk <bunk@stusta.de>
2006-01-15SOFTWARE_SUSPEND: fix a typo in the dependenciesAdrian Bunk
This patch fixes a typo in the dependencies of SOFTWARE_SUSPEND. This patch is based on a report by Jean-Luc Leger <reiga@dspnet.fr.eu.org>. Signed-off-by: Adrian Bunk <bunk@stusta.de> Acked-by: Pavel Machek <pavel@ucw.cz>
2005-11-13[PATCH] move pm_register/etc. to CONFIG_PM_LEGACY, pm_legacy.hJeff Garzik
Since few people need the support anymore, this moves the legacy pm_xxx functions to CONFIG_PM_LEGACY, and include/linux/pm_legacy.h. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-05[PATCH] encrypt suspend data for easy wipingAndreas Steinmetz
The patch protects from leaking sensitive data after resume from suspend. During suspend a temporary key is created and this key is used to encrypt the data written to disk. When, during resume, the data was read back into memory the temporary key is destroyed which simply means that all data written to disk during suspend are then inaccessible so they can't be stolen lateron. Think of the following: you suspend while an application is running that keeps sensitive data in memory. The application itself prevents the data from being swapped out. Suspend, however, must write these data to swap to be able to resume lateron. Without suspend encryption your sensitive data are then stored in plaintext on disk. This means that after resume your sensitive data are accessible to all applications having direct access to the swap device which was used for suspend. If you don't need swap after resume these data can remain on disk virtually forever. Thus it can happen that your system gets broken in weeks later and sensitive data which you thought were encrypted and protected are retrieved and stolen from the swap device.

2005-08-25[ACPI] IA64-related ACPI Kconfig fixesLen Brown
Build issues were mostly in the ACPI=n case -- don't do that. Select ACPI from IA64_GENERIC. Add some missing dependencies on ACPI. Mark BLACKLIST_YEAR and some laptop-only ACPI drivers as X86-only. Let me know when you get an IA64 Laptop. Signed-off-by: Len Brown <len.brown@intel.com>
2005-06-25[PATCH] swsusp: only allow it when it makes sensePavel Machek

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
