PM / Runtime: Automatically retry failed autosuspends

2011-11-04T21:28:14Z

Originally, the runtime PM core would send an idle notification whenever a suspend attempt failed. The idle callback routine could then schedule a delayed suspend for some time later. However this behavior was changed by commit f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle notification after failing suspend). No notifications were sent, and there was no clear mechanism to retry failed suspends. This caused problems for the usbhid driver, because it fails autosuspend attempts as long as a key is being held down. Therefore this patch (as1492) adds a mechanism for retrying failed autosuspends. If the callback routine updates the last_busy field so that the next autosuspend expiration time is in the future, the autosuspend will automatically be rescheduled.

PM / Runtime: Fix runtime accounting calculation error

With delta type being int, its value is made zero for all values of now > 0x80000000. Hence fixing it. Signed-off-by: venu byravarasu Signed-off-by: Rafael J. Wysocki

drivers/base: change module.h -> export.h in power/common.c

2011-10-31T23:31:39Z

This file isn't using full modular functionality, and hence can be "downgraded" to just using export.h Reported-by: Stephen Rothwell Signed-off-by: Paul Gortmaker

drivers/base: base.h implicitly depends on

2011-10-31T23:31:39Z

This file is currently relying on sneaking it in through the implicit include paths from device.h. Once that is cleaned up, this will happen: In file included from drivers/base/init.c:12: drivers/base/base.h:34: error: field ‘bus_notifier’ has incomplete type make[3]: *** [drivers/base/init.o] Error 1 Fix it up in advance, so the cleanup can continue.

drivers/base: dma-coherent.c is a module and needs module.h

2011-10-31T23:31:38Z

It was implicitly getting it before, but it will break compiles once we fix that. Signed-off-by: Paul Gortmaker

drivers/base: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required.

2011-10-31T23:31:38Z

Most of these files were implicitly getting EXPORT_SYMBOL via device.h which was including module.h, but that path will be broken soon. [ with input from Stephen Rothwell ] Signed-off-by: Paul Gortmaker

drivers/base: transport_class explicitly requires EXPORT_SYMBOL

2011-10-31T23:31:15Z

This file was getting via an implicit include path, but we want to crush those out of existence since they cost time during compiles of processing thousands of lines of headers for no reason. Give it the lightweight header that just contains the EXPORT_SYMBOL infrastructure. Signed-off-by: Paul Gortmaker
