Hi Rafael,

nice to see your patchset is in linux-next (next-20101213) now.
More precisely in linux-acpi-2.6: 1/13 + 2/13 in release and rest/13
in test GIT branch.

What about the fix
"Platform-x86-Make-fujitsu_laptop-use-acpi_bus_update_power.patch"
[1]?
Will this go over platform-x86/linux-next into linux-next GIT tree?
Are you co-ordinating this with mjg?

Regards,
- Sedat -

Hi,

Unfortunately there are a few problems with ACPI power resources management
that should be fixed by the following series of patches.

Patch [1/13] is necessary to fix a recent regression in the mainline kernel and
patch [2/13] also should go into 2.6.37 IMO.  The remaining patches are not so
urgent, but they all are necessary.

[1/13] - Fix regression if fan resume resulting from the rework of power
         resources reference counting.

[2/13] - Do not reference count power resources that can't be turned on.

[3/13] - Rework acpi_power_get_inferred_state() so that it doesn't update
         device->power.state behind the caller's back.

[4/13] - Introduce functions for handling lists of power resources.

[5/13] - Introduce helper function for reference counting power resources
         for a given device and power state.

[6/13] - Introduce function for reading device power state without modifying
         the device object.

[7/13] - Add function for device power state initialization.

[8/13] - Add function for updating device power state in a consistent way.

[9/13] - Register acpi_power_driver before scanning the root of the namespace.

[10/13] - Add power resource ACPI device objects as soon as they are needed.

[11/13] - Rework the management of ACPI power resources in the ACPI fan driver.

[12/13] - Drop acpi_bus_get_power() that has no users now.

[13/13] - Drop acpi_power_nocheck which isn't necessary any more.

The patches have been tested on my HP nx6325 (which is the only machine using
ACPI power resources I have) and a combo patch functionally equivalen to this
series has been tested by Maciej Rutecki.

Please apply.

Thanks,
Rafael
