[PATCH] Export pm_suspend for the shared APM emulation

2006-12-07T16:39:32+00:00

The new shared APM emulation just like its ARM and MIPS predecessors uses
pm_suspend() which was only exported on SH.  Move export to close to it's
definition where it really should be anyway.

[PATCH] convert pm_sem to a mutex

2006-12-07T16:39:28+00:00

The power management semaphore is only used as mutex, so convert it.

[PATCH] Add include/linux/freezer.h and move definitions from sched.h

2006-12-07T16:39:27+00:00

Move process freezing functions from include/linux/sched.h to freezer.h, so
that modifications to the freezer or the kernel configuration don't require
recompiling just about everything.

ACPI: S4: Use "platform" rather than "shutdown" mode by default

2006-11-02T03:40:23+00:00

It has been reported that on some systems the functionality after a resume
from disk is limited if the system is simply powered off during the suspend
instead of using the ACPI S4 suspend (aka platform mode).

Unfortunately the default is currently to power off the system during the
suspend so the users of these systems experience problems after the resume
if they don't switch to the platform mode explicitly.  This patch makes swsusp
use the platform mode by default to avoid such situations.

[PATCH] PM: Add pm_trace switch

2006-09-26T15:49:04+00:00

Add the pm_trace attribute in /sys/power which has to be explicitly set to
one to really enable the "PM tracing" code compiled in when CONFIG_PM_TRACE
is set (which modifies the machine's CMOS clock in unpredictable ways).

[PATCH] Disable CPU hotplug during suspend

2006-09-26T15:48:59+00:00

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.

Add support for suspending and resuming the whole console subsystem

2006-06-20T01:16:01+00:00

Trying to suspend/resume with console messages flying all around is
doomed to failure, when the devices that the messages are trying to
go to are being shut down.
