PM / Domains: Fix build for CONFIG_PM_RUNTIME unset

2011-08-14T11:34:31Z

Function genpd_queue_power_off_work() is not defined for CONFIG_PM_RUNTIME, so pm_genpd_poweroff_unused() causes a build error to happen in that case. Fix the problem by making pm_genpd_poweroff_unused() depend on CONFIG_PM_RUNTIME too. Signed-off-by: Rafael J. Wysocki

PM: Allow the clocks management code to be used during system suspend

2011-07-02T12:29:56Z

The common clocks management code in drivers/base/power/clock_ops.c is going to be used during system-wide power transitions as well as for runtime PM, so it shouldn't depend on CONFIG_PM_RUNTIME. However, the suspend/resume functions provided by it for CONFIG_PM_RUNTIME unset, to be used during system-wide power transitions, should not behave in the same way as their counterparts defined for CONFIG_PM_RUNTIME set, because in that case the clocks are managed differently at run time. The names of the functions still contain the word "runtime" after this change, but that is going to be modified by a separate patch later. Signed-off-by: Rafael J. Wysocki Reviewed-by: Kevin Hilman

PM / Domains: Support for generic I/O PM domains (v8)

2011-07-02T12:29:55Z

Introduce common headers, helper functions and callbacks allowing platforms to use simple generic power domains for runtime power management. Introduce struct generic_pm_domain to be used for representing power domains that each contain a number of devices and may be parent domains or subdomains with respect to other power domains. Among other things, this structure includes callbacks to be provided by platforms for performing specific tasks related to power management (i.e. ->stop_device() may disable a device's clocks, while ->start_device() may enable them, ->power_off() is supposed to remove power from the entire power domain and ->power_on() is supposed to restore it). Introduce functions that can be used as power domain runtime PM callbacks, pm_genpd_runtime_suspend() and pm_genpd_runtime_resume(), as well as helper functions for the initialization of a power domain represented by a struct generic_power_domain object, adding a device to or removing a device from it and adding or removing subdomains. Introduce configuration option CONFIG_PM_GENERIC_DOMAINS to be selected by the platforms that want to use the new code. Signed-off-by: Rafael J.

PM: Remove CONFIG_PM_VERBOSE

2011-05-17T21:25:10Z

Now that we have CONFIG_DYNAMIC_DEBUG there is no need for yet another flag causing dev_dbg() and pr_debug() statements in the core PM code to produce output. Moreover, CONFIG_PM_VERBOSE causes so much output to be generated that it's not really useful and almost no one sets it.

PM / Runtime: Generic clock manipulation rountines for runtime PM (v6)

2011-04-29T22:25:44Z

Many different platforms and subsystems may want to disable device clocks during suspend and enable them during resume which is going to be done in a very similar way in all those cases. For this reason, provide generic routines for the manipulation of device clocks during suspend and resume. Convert the ARM shmobile platform to using the new routines. Signed-off-by: Rafael J.

PM / Hibernate: Introduce CONFIG_HIBERNATE_CALLBACKS

2011-04-11T20:54:42Z

Xen save/restore is going to use hibernate device callbacks for quiescing devices and putting them back to normal operations and it would need to select CONFIG_HIBERNATION for this purpose. However, that also would cause the hibernate interfaces for user space to be enabled, which might confuse user space, because the Xen kernels don't support hibernation. Moreover, it would be wasteful, as it would make the Xen kernels include a substantial amount of code that they would never use. To address this issue introduce new power management Kconfig option CONFIG_HIBERNATE_CALLBACKS, such that it will only select the code that is necessary for the hibernate device callbacks to work and make CONFIG_HIBERNATION select it. Then, Xen save/restore will be able to select CONFIG_HIBERNATE_CALLBACKS without dragging the entire hibernate code along with it. Signed-off-by: Rafael J. Wysocki Tested-by: Shriram Rajagopalan

PM: Simplify kernel/power/Kconfig

2011-03-14T23:43:17Z

'n' defaults are pretty pointless and actually bogus when used with prompt-less config options. The "bool"/"default y" pair with no prompt can be expressed more compactly using def_bool.
