Fix /proc/acpi/alarm BCD alarm encodings

2007-10-25T22:08:03Z

This fixes some totally illogical and wrong code that converts things to and from BCD mode essentially randomly, does math on values in BCD mode etc etc. Introduce a few helper functions to make it a bit more obvious what is going on, and make sure that we always do all the arithmetic (and anythign else, for that matter) in binary, not BCD. Tested by Mark Lord, who found the problem originally, and also pushed the patch back and reminded me about it. Signed-off-by: Mark Lord Signed-off-by: Linus Torvalds

ACPI: (more) delete CONFIG_ACPI_PROCFS_SLEEP (again)

ACPI: restore CONFIG_ACPI_SLEEP

2007-07-29T23:53:59Z

Restore the 2.6.22 CONFIG_ACPI_SLEEP build option, but now shadowing the new CONFIG_PM_SLEEP option. Signed-off-by: Len Brown [ Modified to work with the PM config setup changes. ] Signed-off-by: Linus Torvalds

Introduce CONFIG_SUSPEND for suspend-to-Ram and standby

2007-07-29T23:45:38Z

Introduce CONFIG_SUSPEND representing the ability to enter system sleep states, such as the ACPI S3 state, and allow the user to choose SUSPEND and HIBERNATION independently of each other. Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has been chosen and the kernel is intended for SMP systems. Also, introduce CONFIG_PM_SLEEP which is automatically selected if CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the code needed for both suspend and hibernation. The top-level power management headers and the ACPI code related to suspend and hibernation are modified to use the new definitions (the changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce the number of ifdefs). There are many other files in which CONFIG_PM can be replaced with CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in the future. Signed-off-by: Rafael J.

Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION

2007-07-29T23:45:38Z

Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION to avoid confusion (among other things, with CONFIG_SUSPEND introduced in the next patch). Signed-off-by: Rafael J. Wysocki Signed-off-by: Linus Torvalds

ACPI: Kconfig: fold /proc/acpi/sleep under CONFIG_ACPI_PROCFS

2007-07-24T06:16:50Z

/proc/acpi/sleep has had its own "default n" option, ACPI_SLEEP_PROC_SLEEP, for many months. Time to delete ACPI_SLEEP_PROC_SLEEP. Users that still need /proc/acpi/sleep can still get it along with the other deprecated /proc/acpi files by enabling CONFIG_ACPI_PROCFS. Also delete ACPI_SLEEP_PROC_FS, which was an umbrella for /proc/acpi/sleep, wakeup, alarm, because it was effectively just a synonym for ACPI_SLEEP. Signed-off-by: Len Brown

PM: Separate hibernation code from suspend code

2007-05-09T19:30:48Z

[ 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

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()

2007-05-07T19:12:59Z

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.
