PM: Rework handling of interrupts during suspend-resume

2009-03-30T19:46:54Z

Use the functions introduced in by the previous patch, suspend_device_irqs(), resume_device_irqs() and check_wakeup_irqs(), to rework the handling of interrupts during suspend (hibernation) and resume. Namely, interrupts will only be disabled on the CPU right before suspending sysdevs, while device drivers will be prevented from receiving interrupts, with the help of the new helper function, before their "late" suspend callbacks run (and analogously during resume). In addition, since the device interrups are now disabled before the CPU has turned all interrupts off and the CPU will ACK the interrupts setting the IRQ_PENDING bit for them, check in sysdev_suspend() if any wake-up interrupts are pending and abort suspend if that's the case.

PM: Split up sysdev_[suspend|resume] from device_power_[down|up], fix

2009-02-22T21:09:33Z

Impact: module build fix Fix: ERROR: "sysdev_resume" [arch/x86/kernel/apm.ko] undefined! ERROR: "sysdev_suspend" [arch/x86/kernel/apm.ko] undefined! As these APIs are now used by the APM driver, which can be built as a module. Also fix a few extra (and inconsistent) newlines in comment blocks preceding these functions. Signed-off-by: Ingo Molnar

sysfs: Fix return values for sysdev_store_{ulong,int}

2008-10-29T22:03:49Z

SYSFS: Fix return values for sysdev_store_{ulong,int} Always return the full size instead of the consumed length of the string in sysdev_store_{ulong,int} This avoids EINVAL errors in some echo versions. Signed-off-by: Andi Kleen Cc: stable Signed-off-by: Greg Kroah-Hartman

driver core: drivers/base/sys.c: update comments

2008-10-29T22:03:49Z

There are no functions named sys_device_shutdown or sys_device_suspend in the kernel. They should be fixed to sysdev_shutdown and sysdev_suspend respectively. Signed-off-by: Qinghuang Feng Signed-off-by: Greg Kroah-Hartman

Use WARN() in drivers/base/

2008-07-26T19:00:07Z

Use WARN() instead of a printk+WARN_ON() pair; this way the message becomes part of the warning section for better reporting/collection. Signed-off-by: Arjan van de Ven Cc: Greg KH Cc: Kay Sievers Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sysdev: Add utility functions for simple int/ulong variable sysdev attributes

2008-07-22T04:55:02Z

This adds a new sysdev_ext_attribute that stores a pointer to the variable it manages and some utility functions/macro to easily use them. Previously all users wrote custom macros to generate show/store functions for each variable, with this it is possible to avoid that in many cases.

sysdev: Pass the attribute to the low level sysdev show/store function

2008-07-22T04:55:02Z

This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections.
