PM: Separate hibernation code from suspend code

2007-05-09T19:30:48+00:00

[ With Johannes Berg ] Separate the hibernation (aka suspend to disk code) from the other suspend code. In particular: * Remove the definitions related to hibernation from include/linux/pm.h * Introduce struct hibernation_ops and a new hibernate() function to hibernate the system, defined in include/linux/suspend.h * Separate suspend code in kernel/power/main.c from hibernation-related code in kernel/power/disk.c and kernel/power/user.c (with the help of hibernation_ops) * Switch ACPI (the only user of pm_ops.pm_disk_mode) to hibernation_ops Signed-off-by: Rafael J.

ACPI wakeup hooks for rtc-cmos

2007-05-08T18:15:18+00:00

Remove /proc/acpi/alarm file when the rtc-cmos "wakealarm" file is available. Instead, provide hooks that rtc-cmos will use. Signed-off-by: David Brownell Cc: Alessandro Zummo Cc: Len Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

remove software_suspend()

2007-05-07T19:12:59+00:00

Remove software_suspend() and all its users since pm_suspend(PM_SUSPEND_DISK) should be equivalent and there's no point in having two interfaces for the same thing. The patch also changes the valid_state function to return 0 (false) for PM_SUSPEND_DISK when SOFTWARE_SUSPEND is not configured instead of accepting it and having the whole thing fail later.

power management: implement pm_ops.valid for everybody

2007-04-30T23:40:40+00:00

Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

ACPI: make /proc/acpi/wakeup more useful

2007-04-25T19:20:10+00:00

This updates /proc/acpi/wakeup to be more informative, primarily by showing the sysfs node associated with each wakeup-enabled device. Example: Device S-state Status Sysfs node PCI0 S4 disabled no-bus:pci0000:00 PS2M S4 disabled pnp:00:05 PS2K S4 disabled pnp:00:06 UAR1 S4 disabled pnp:00:08 USB1 S3 disabled pci:0000:00:03.0 USB2 S3 disabled pci:0000:00:03.1 USB3 S3 disabled USB4 S3 disabled pci:0000:00:03.3 S139 S4 disabled LAN S4 disabled pci:0000:00:04.0 MDM S4 disabled AUD S4 disabled pci:0000:00:02.7 SLPB S4 *enabled Eventually this file should be removed, but until then it's almost the only way we have to tell how the relevant ACPI tables are broken (and cope). In that example, two devices don't actually exist (USB3, S139), one can't issue wakeup events (PCI0), and two seem harmlessly (?) confused (MDM and AUD are the same PCI device, but it's the _modem_ that does wake-on-ring). In particular, we need to be sure driver model nodes are properly hooked up before we can get rid of this ACPI-only interface for wakeup events.

[PATCH] remove many unneeded #includes of sched.h

2007-02-14T16:09:54+00:00

After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
