Rather than having the regulator init data read from the platform_data member of the struct device that is registered for the regulator make the init data an explict argument passed in when registering.

由 David Brownell 提交于
Based on previous LKML discussions: * Update docs for regulator sysfs class attributes to highlight the fact that all current attributes are intended to be control inputs, including notably "state" and "opmode" which previously implied otherwise. * Define a new regulator driver get_status() method, which is the first method reporting regulator outputs instead of inputs. It can report on/off and error status; or instead of simply "on", report the actual operating mode. For the moment, this is a sysfs-only interface, not accessible to regulator clients. Such clients can use the current notification interfaces to detect errors, if the regulator reports them.

Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454Signed-off-by: NAlexey Dobriyan <adobriyan@gmail.com>

struct proc_dir_entry::owner is going to be removed. Now it's only necessary to protect PDEs which are using ->read_proc, ->write_proc hooks. However, ->owner assignments are racy and make it very easy for someone to switch ->owner on live PDE (as some subsystems do) without fixing refcounts and so on. http://bugzilla.kernel.org/show_bug.cgi?id=12454 So, ->owner is on death row. Proxy file operations exist already (proc_file_operations), just bump usecount when necessary. Signed-off-by: NAlexey Dobriyan <adobriyan@gmail.com>

If the device is not supposed to wake up the system, ie. when device_may_wakeup(&dev->dev) returns 'false', pci_prepare_to_sleep() should pass 'false' to pci_enable_wake() so that it calls the platform to disable the wake-up capability of the device.

由 Rafael J. Wysocki 提交于
The radeonfb driver needs to program the device's PMCSR directly due to some quirky hardware it has to handle (see http://bugzilla.kernel.org/show_bug.cgi?id=12846 for details) and after doing that it needs to call the platform (usually ACPI) to finish the power transition of the device. Currently it uses pci_set_power_state() for this purpose, however making a specific assumption about the internal behavior of this function, which has changed recently so that this assumption is no longer satisfied. For this reason, introduce __pci_complete_power_transition() that may be called by the radeonfb driver to complete the power transition of the device. For symmetry, introduce __pci_start_power_transition(). Signed-off-by: NRafael J. Wysocki <rjw@sisk.pl> Acked-by: NJesse Barnes <jbarnes@virtuousgeek.org>

At present the configuration spaces of PCI devices that have no drivers or no PM support in the drivers (either legacy or through a pm object) are not saved during suspend and, consequently, they are not restored during resume. This generally may lead to the state of the system being slightly inconsistent after the resume, so it's better to save and restore the configuration spaces of these devices as well.

由 Rafael J. Wysocki 提交于
There is a problem with PCI devices without any PM support (either native or through the platform) that pci_set_power_state() always returns error code for them, even if they are being put into D0. However, such devices are always in D0, so pci_set_power_state() should return success when attempting to put such a device into D0. It also should update the current_state field for these devices as appropriate. This modification is necessary so that the standard configuration registers of these devices are successfully restored by pci_restore_standard_config() during the "early" phase of resume. In addition, pci_set_power_state() should check the value of current_state before calling the platform to change the power state of the device to avoid doing that unnecessarily.

由 Rafael J. Wysocki 提交于
Once we have allowed timer interrupts to be enabled during the late phase of suspending devices, we are now able to use the generic pci_set_power_state() to put PCI devices into low power states at that time. We can also use some related platform callbacks, like the ones preparing devices for wake-up, during the late suspend. Doing this will allow us to avoid the race condition where a device using shared interrupts is put into a low power state with interrupts enabled and then an interrupt (for another device) comes in and confuses its driver. At the same time, devices that don't support the native PCI PM or that require some additional, platform-specific operations to be carried out to put them into low power states will be handled as appropriate.

Once we have allowed timer interrupts to be enabled during the early phase of resuming devices, we are now able to use the generic pci_set_power_state() to put PCI devices into D0 at that time. Then, the platform-specific PM code will have a chance to handle devices that don't implement the native PCI PM or that require some additional, platform-specific operations to be carried out to power them up.

Change the ordering of the hibernation core code so that the platform "prepare" callbacks are executed and the nonboot CPUs are disabled after calling device drivers' "late suspend" methods. This change (along with the previous analogous change of the suspend core code) will allow us to rework the PCI PM core so that the power state of devices is changed in the "late" phase of suspend (and analogously in the "early" phase of resume), which in turn will allow us to avoid the race condition where a device using shared interrupts is put into a low power state with interrupts enabled and then an interrupt (for another device) comes in and confuses its driver.
