* ACPI: Properly clear flags on false-positives and send uevent on sudden unplugHolger Macht2008-08-14
| | | | | | | | | | | | | | Some devices emit a ACPI_NOTIFY_DEVICE_CHECK while physically unplugging even if the software undock has already been done and dock_present() check fails. However, the internal flags need to be cleared (complete_undock()). Also, even notify userspace if the dock station suddently went away without proper software undocking. This happens on a Acer TravelMate 3000 Signed-off-by: Holger Macht <hmacht@suse.de> Signed-off-by: Andi Kleen <ak@linux.intel.com>
* APCI: revert duplicated patchThomas Gleixner2008-07-20
| | | | | | | | | | | | | | | commit 816c2eda3ce8fa7eb62f22e01e2ec7a3f7d677c0 ("dock: bay: Don't call acpi_walk_namespace() when ACPI is disabled.") was merged between 2.6.26-rc8 and -rc9) Due to rebasing the ACPI tree via quilt the same patch got applied again via commit cc7e51666d82aedfd6b9a033ca1a10d71c21f1ca ("dock: bay: Don't call acpi_walk_namespace() when ACPI is disabled.")

* ACPI: Set flag DOCK_UNDOCKING when triggered via sysfsHolger Macht2008-03-18
| | | | | | | | | | | | | begin_undock() is only called when triggered via a acpi notify handler (pressing the undock button on the dock station), but complete_undock() is always called after the eject. So if a undock is triggered through a sysfs write, the flag DOCK_UNDOCKING has to be set for the dock station, too. Otherwise this will freeze the system hard.

* ACPI: dock: add immediate_undock optionKristen Carlson Accardi2007-05-10
| | | | | | | | | | | | | | | | | | | | Allow the driver to be loaded with an option that will allow userspace to control whether the laptop is ejected immediately when the user presses the button, or only when the syfs undock file is written. if immediate_undock == 1, then when the user presses the undock button, the laptop will send an event to userspace to notify userspace of the undock, but then immediately undock without waiting for userspace. This is the current behavior, and I set this to be the default. if immediate_undock == 0, then when the user presses the undock button, the laptop will send an event to userspace and do nothing. User space can query the "flags" sysfs entry to determine if an undock request has been made by the user (if bit 1 is set). User space will then need to write the undock sysfs entry to complete the undocking process.
