remove "struct subsystem" as it is no longer needed

2007-05-03T01:57:59+00:00

We need to work on cleaning up the relationship between kobjects, ksets and
ktypes.  The removal of 'struct subsystem' is the first step of this,
especially as it is not really needed at all.

Thanks to Kay for fixing the bugs in this patch.

define platform wakeup hook, use in pci_enable_wake()

2007-04-27T17:57:33+00:00

This defines a platform hook to enable/disable a device as a wakeup event
source.  It's initially for use with ACPI, but more generally it could be used
whenever enable_irq_wake()/disable_irq_wake() don't suffice.

The hook is called -- if available -- inside pci_enable_wake(); and the
semantics of that call are enhanced so that support for PCI PME# is no longer
needed.  It can now work for devices with "legacy PCI PM", when platform
support allows it.  (That support would use some board-specific signal for for
the same purpose as PME#.)

Driver core: remove use of rwsem

2007-04-27T17:57:30+00:00

This lock is never used by the rest of the driver core, so the fact that
we are grabbing it here means it isn't correct...

Driver core: add suspend() and resume() to struct device_type

Driver core: add suspend() and resume() to struct device_type

In cases when there are devices of different types in the same class
we can't use class's implementation of suspend and resume methods and
we need to add them to struct device_type instead.

Also fix error handling in resume code (we should not try to call
class's resume method iof bus's resume method for the device failed.

[PATCH] PM: use kobject_name() to access kobject names

2007-04-11T22:39:39+00:00

Noone should use kobj.name directly since it may contain garbage.
Objects with longer names have them stored in separately allocated
memory pointed to by kobj->k_name.

PM: device_suspend/resume may sleep

This adds warning when someone tries them from atomic context.

PM: no suspend_prepare() phase

2006-09-26T04:08:38+00:00

Remove the new suspend_prepare() phase.  It doesn't seem very usable,
has never been tested, doesn't address fault cleanup, and would need
a sibling resume_complete(); plus there are no real use cases.  It
could be restored later if those issues get resolved.

PM: add kconfig option for deprecated .../power/state files

2006-09-26T04:08:37+00:00

Add a new PM_SYSFS_DEPRECATED config option to control whether or
not the /sys/devices/.../power/state files are provided.  This will
make it easier to get rid of that mechanism when the time comes,
and to verify that userspace tools work right without it.

PM: update docs for writing .../power/state

2006-09-26T04:08:37+00:00

Updates to match current code:

 - Make writes to the /sys/devices/.../power/state files fail cleanly
   if the device requires the irqs-off call variants.

 - Fix comments describing the /sys/devices/.../power/state file writes
   to match the code; the last several releases have invalidated the
   previous text.
