Wysocki <rjw@sisk.pl>, Novell Inc. + +1. Introduction + +Support for run-time power management (run-time PM) of I/O devices is provided +at the power management core (PM core) level by means of: + +* The power management workqueue pm_wq in which bus types and device drivers can + put their PM-related work items. It is strongly recommended that pm_wq be + used for queuing all work items related to run-time PM, because this allows + them to be synchronized with system-wide power transitions (suspend to RAM, + hibernation and resume from system sleep states). pm_wq is declared in + include/linux/pm_runtime.h and defined in kernel/power/main.c. + +* A number of run-time PM fields in the 'power' member of 'struct device' (which + is of the type 'struct dev_pm_info', defined in include/linux/pm.h) that can + be used for synchronizing run-time PM operations with one another. + +* Three device run-time PM callbacks in 'struct dev_pm_ops' (defined in + include/linux/pm.h). + +* A set of helper functions defined in drivers/base/power/runtime.c that can be + used for carrying out run-time PM operations in such a way that the + synchronization between them is taken care of by the PM core. Bus types and + device drivers are encouraged to use these functions. + +The run-time PM callbacks present in 'struct dev_pm_ops', the device run-time PM +fields of 'struct dev_pm_info' and the core helper functions provided for +run-time PM are described below. + +2. Device Run-time PM Callbacks + +There are three device run-time PM callbacks defined in 'struct dev_pm_ops': + +struct dev_pm_ops { + ... + int (*runtime_suspend)(struct device *dev); + int (*runtime_resume)(struct device *dev); + void (*runtime_idle)(struct device *dev); + ... +}; + +The ->runtime_suspend() callback is executed by the PM core for the bus type of +the device being suspended. The bus type's callback is then _entirely_ +_responsible_ for handling the device as appropriate, which may, but need not +include executing the device driver's own ->runtime_suspend() callback (from the +PM core's point of view it is not necessary to implement a ->runtime_suspend() +callback in a device driver as long as the bus type's ->runtime_suspend() knows +what to do to handle the device). + + * Once the bus type's ->runtime_suspend() callback has completed successfully + for given device, the PM core regards the device as suspended, which need + not mean that the device has been put into a low power state. It is + supposed to mean, however, that the device will not process data and will + not communicate with the CPU(s) and RAM until its bus type's + ->runtime_resume() callback is executed for it. The run-time PM status of + a device after successful execution of its bus type's ->runtime_suspend() + callback is 'suspended'. + + * If the bus type's ->runtime_suspend() callback returns -EBUSY or -EAGAIN, + the device's run-time PM status is supposed to be 'active', which means that + the device _must_ be fully operational afterwards. + + * If the bus type's ->runtime_suspend() callback returns an error code + different from -EBUSY or -EAGAIN, the PM core regards this as a fatal + error and will refuse to run the helper functions described in Section 4 + for the device, until the status of it is directly set either to 'active' + or to 'suspended' (the PM core provides special helper functions for this + purpose). + +In particular, if the driver requires remote wakeup capability for proper +functioning and device_may_wakeup() returns 'false' for the device, then +->runtime_suspend() should return -EBUSY. On the other hand, if +device_may_wakeup() returns 'true' for the device and the device is put +into a low power state during the execution of its bus type's +->runtime_suspend(), it is expected that remote wake-up (i.e. hardware mechanism +allowing the device to request a change of its power state, such as PCI PME) +will be enabled for the device. Generally, remote wake-up should be enabled +for all input devices put into a low power state at run time. + +The ->runtime_resume() callback is executed by the PM core for the bus type of +the device being woken up. The bus type's callback is then _entirely_ +_responsible_ for handling the device as appropriate, which may, but need not +include executing the device driver's own ->runtime_resume() callback (from the +PM core's point of view it is not necessary to implement a ->runtime_resume() +callback in a device driver as long as the bus type's ->runtime_resume() knows +what to do to handle the device). + + * Once the bus type's ->runtime_resume() callback has completed successfully, + the PM core regards the device as fully operational, which means that the + device _must_ be able to complete I/O operations as needed. The run-time + PM status of the device is then 'active'. + + * If the bus type's ->runtime_resume() callback returns an error code, the PM + core regards this as a fatal error and will refuse to run the helper + functions described in Section 4 for the device, until its status is + directly set either to 'active' or to 'suspended' (the PM core provides + special helper functions for this purpose). + +The ->runtime_idle() callback is executed by the PM core for the bus type of +given device whenever the device appears to be idle, which is indicated to the +PM core by two counters, the device's usage counter and the counter of 'active' +children of the device. + + * If any of these counters is decreased using a helper function provided by + the PM core and it turns out to be equal to zero, the other counter is + checked. If that counter also is equal to zero, the PM core executes the + device bus type's ->runtime_idle() callback (with the device as an + argument). + +The action performed by a bus type's ->runtime_idle() callback is totally +dependent on the bus type in question, but the expected and recommended action +is to check if the device can be suspended (i.e. if all of the conditions +necessary for suspending the device are satisfied) and to queue up a suspend +request for the device in that case. + +The helper functions provided by the PM core, described in Section 4, guarantee +that the following constraints are met with respect to the bus type's run-time +PM callbacks: + +(1) The callbacks are mutually exclusive (e.g. it is forbidden to execute + ->runtime_suspend() in parallel with ->runtime_resume() or with another + instance of ->runtime_suspend() for the same device) with the exception that + ->runtime_suspend() or ->runtime_resume() can be executed in parallel with + ->runtime_idle() (although ->runtime_idle() will not be started while any + of the other callbacks is being executed for the same device). + +(2) ->runtime_idle() and ->runtime_suspend() can only be executed for 'active' + devices (i.e. the PM core will only execute ->runtime_idle() or + ->runtime_suspend() for the devices the run-time PM status of which is + 'active'). + +(3) ->runtime_idle() and ->runtime_suspend() can only be executed for a device + the usage counter of which is equal to zero _and_ either the counter of + 'active' children of which is equal to zero, or the 'power.ignore_children' + flag of which is set. + +(4) ->runtime_resume() can only be executed for 'suspended' devices (i.e. the + PM core will only execute ->runtime_resume() for the devices the run-time + PM status of which is 'suspended'). + +Additionally, the helper functions provided by the PM core obey the following +rules: + + * If ->runtime_suspend() is about to be executed or there's a pending request + to execute it, ->runtime_idle() will not be executed for the same device. + + * A request to execute or to schedule the execution of ->runtime_suspend() + will cancel any pending requests to execute ->runtime_idle() for the same + device. + + * If ->runtime_resume() is about to be executed or there's a pending request + to execute it, the other callbacks will not be executed for the same device. + + * A request to execute ->runtime_resume() will cancel any pending or + scheduled requests to execute the other callbacks for the same device. + +3.

Run-time PM Device Helper Functions + +The following run-time PM helper functions are defined in +drivers/base/power/runtime.c and include/linux/pm_runtime.h: + + void pm_runtime_init(struct device *dev);

+ - execute ->runtime_resume() for the device's bus type; returns 0 on + success, 1 if the device's run-time PM status was already 'active' or + error code on failure, where -EAGAIN means it may be safe to attempt to + resume the device again in future, but 'power.runtime_error' should be + checked additionally + + int pm_request_idle(struct device *dev); + - submit a request to execute ->runtime_idle() for the device's bus type + (the request is represented by a work item in pm_wq); returns 0 on success + or error code if the request has not been queued up + + int pm_schedule_suspend(struct device *dev, unsigned int delay); + - schedule the execution of ->runtime_suspend() for the device's bus type + in future, where 'delay' is the time to wait before queuing up a suspend + work item in pm_wq, in milliseconds (if 'delay' is zero, the work item is + queued up immediately); returns 0 on success, 1 if the device's PM + run-time status was already 'suspended', or error code if the request + hasn't been scheduled (or queued up if 'delay' is 0); if the execution of + ->runtime_suspend() is already scheduled and not yet expired, the new + value of 'delay' will be used as the time to wait + + int pm_request_resume(struct device *dev); + - submit a request to execute ->runtime_resume() for the device's bus type + (the request is represented by a work item in pm_wq); returns 0 on + success, 1 if the device's run-time PM status was already 'active', or + error code if the request hasn't been queued up + + void pm_runtime_get_noresume(struct device *dev); + - increment the device's usage counter + + int pm_runtime_get(struct device *dev); + - increment the device's usage counter, run pm_request_resume(dev) and + return its result + + int pm_runtime_get_sync(struct device *dev);

+ - enable the run-time PM helper functions to run the device bus type's + run-time PM callbacks described in Section 2 + + int pm_runtime_disable(struct device *dev); + - prevent the run-time PM helper functions from running the device bus + type's run-time PM callbacks, make sure that all of the pending run-time + PM operations on the device are either completed or canceled; returns + 1 if there was a resume request pending and it was necessary to execute + ->runtime_resume() for the device's bus type to satisfy that request, + otherwise 0 is returned + + void pm_suspend_ignore_children(struct device *dev, bool enable); + - set/unset the power.ignore_children flag of the device + + int pm_runtime_set_active(struct device *dev); + - clear the device's 'power.runtime_error' flag, set the device's run-time + PM status to 'active' and update its parent's counter of 'active' + children as appropriate (it is only valid to use this function if + 'power.runtime_error' is set or 'power.disable_depth' is greater than + zero); it will fail and return error code if the device has a parent + which is not active and the 'power.ignore_children' flag of which is unset + + void pm_runtime_set_suspended(struct device *dev); + - clear the device's 'power.runtime_error' flag, set the device's run-time + PM status to 'suspended' and update its parent's counter of 'active' + children as appropriate (it is only valid to use this function if + 'power.runtime_error' is set or 'power.disable_depth' is greater than + zero) + +It is safe to execute the following helper functions from interrupt context: + +pm_request_idle() +pm_schedule_suspend() +pm_request_resume() +pm_runtime_get_noresume() +pm_runtime_get() +pm_runtime_put_noidle() +pm_runtime_put() +pm_suspend_ignore_children() +pm_runtime_set_active() +pm_runtime_set_suspended() +pm_runtime_enable() + +5. Run-time PM Initialization, Device Probing and Removal + +Initially, the run-time PM is disabled for all devices, which means that the +majority of the run-time PM helper funtions described in Section 4 will return +-EAGAIN until pm_runtime_enable() is called for the device. + +In addition to that, the initial run-time PM status of all devices is +'suspended', but it need not reflect the actual physical state of the device. +Thus, if the device is initially active (i.e. it is able to process I/O), its +run-time PM status must be changed to 'active', with the help of +pm_runtime_set_active(), before pm_runtime_enable() is called for the device. + +However, if the device has a parent and the parent's run-time PM is enabled, +calling pm_runtime_set_active() for the device will affect the parent, unless +the parent's 'power.ignore_children' flag is set. Namely, in that case the +parent won't be able to suspend at run time, using the PM core's helper +functions, as long as the child's status is 'active', even if the child's +run-time PM is still disabled (i.e. pm_runtime_enable() hasn't been called for +the child yet or pm_runtime_disable() has been called for it). For this reason, +once pm_runtime_set_active() has been called for the device, pm_runtime_enable() +should be called for it too as soon as reasonably possible or its run-time PM +status should be changed back to 'suspended' with the help of +pm_runtime_set_suspended(). + +If the default initial run-time PM status of the device (i.e. 'suspended') +reflects the actual state of the device, its bus type's or its driver's +->probe() callback will likely need to wake it up using one of the PM core's +helper functions described in Section 4. In that case, pm_runtime_resume() +should be used. Of course, for this purpose the device's run-time PM has to be +enabled earlier by calling pm_runtime_enable(). + +If the device bus type's or driver's ->probe() or ->remove() callback runs +pm_runtime_suspend() or pm_runtime_idle() or their asynchronous counterparts, +they will fail returning -EAGAIN, because the device's usage counter is +incremented by the core before executing ->probe() and ->remove(). Still, it +may be desirable to suspend the device as soon as ->probe() or ->remove() has +finished, so the PM core uses pm_runtime_idle_sync() to invoke the device bus +type's ->runtime_idle() callback at that time. diff --git a/arch/arm/include/asm/device.h b/arch/arm/include/asm/device.h index c61642b4060..9f390ce335c 100644 --- a/arch/arm/include/asm/device.h +++ b/arch/arm/include/asm/device.h @@ -12,4 +12,7 @@ struct dev_archdata { #endif };
