[PATCH] swsusp: debugging

2006-11-03T20:27:58Z

Add a swsusp debugging mode. This does everything that's needed for a suspend except for actually suspending. So we can look in the log messages and work out a) what code is being slow and b) which drivers are misbehaving. (1) # echo testproc > /sys/power/disk # echo disk > /sys/power/state This should turn off the non-boot CPU, freeze all processes, wait for 5 seconds and then thaw the processes and the CPU. (2) # echo test > /sys/power/disk # echo disk > /sys/power/state This should turn off the non-boot CPU, freeze all processes, shrink memory, suspend all devices, wait for 5 seconds, resume the devices etc. Cc: Pavel Machek Cc: Stefan Seyfried Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] swsusp: Use suspend_console

2006-10-11T18:14:14Z

Add suspend_console() and resume_console() to the suspend-to-disk code paths so that the users of netconsole can use swsusp with it. Signed-off-by: Rafael J. Wysocki Acked-by: Pavel Machek Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Disable CPU hotplug during suspend

2006-09-26T15:48:59Z

The current suspend code has to be run on one CPU, so we use the CPU hotplug to take the non-boot CPUs offline on SMP machines. However, we should also make sure that these CPUs will not be enabled by someone else after we have disabled them. The functions disable_nonboot_cpus() and enable_nonboot_cpus() are moved to kernel/cpu.c, because they now refer to some stuff in there that should better be static. Also it's better if disable_nonboot_cpus() returns an error instead of panicking if something goes wrong, and enable_nonboot_cpus() has no reason to panic(), because the CPUs may have been enabled by the userland before it tries to take them online.

PM: issue PM_EVENT_PRETHAW

2006-09-26T04:08:37Z

This patch is the first of this series that should actually change any behavior ... by issuing the new event, now tha the rest of the kernel is prepared to receive it. This converts the PM core to issue the new PRETHAW message, which the rest of the kernel is now ready to receive. Signed-off-by: David Brownell Cc: "Rafael J.

[PATCH] swsusp: freeze user space processes first

2006-03-23T15:38:08Z

Allow swsusp to freeze processes successfully under heavy load by freezing userspace processes before kernel threads. [Thanks to Nigel Cunningham for suggesting the way to go.] Signed-off-by: Rafael J. Wysocki Acked-by: Pavel Machek Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] swsusp: low level interface

2006-03-23T15:38:07Z

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.
