2007-10-25ACPI: Fan: Drop force_power_state acpi_device optionAlexey Starikovskiy1-2/+1
force_power_state was used as a workaround for invalid cached power state of the device. We do not cache power state, so no need for workaround. Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Acked-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>

2007-09-27ACPI: Add acpi_bus_generate_event4() functionAlexey Starikovskiy1-0/+1
acpi_bus_generate_event() takes two strings out of passed device object. SBS needs to supply these strings directly. Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
2007-09-27ACPI: Hibernate erroneously disabled Suspend wakeup devicesAlexey Starikovskiy1-1/+0
S4 suspend to disk will disable GPE's permanently because acpi_gpe_sleep_prepare() does not have a counterpart at resume time. Thus, those devices became unavailable for wakeup from subsequent S3 suspend-to-ram. Here acpi_gpe_sleep_prepare() is removed, and upon suspend acpi_enable_wakeup_device() gets its functionality. Upon resume, acpi_disable_wakeup_device() restores the state. https://bugzilla.novell.com/show_bug.cgi?id=292300 Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Acked-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Len Brown <len.brown@intel.com>
2007-08-23ACPI: Schedule /proc/acpi/event for removalLen Brown1-1/+6
Schedule /proc/acpi/event for removal in 6 months. Re-name acpi_bus_generate_event() to acpi_bus_generate_proc_event() to make sure there is no confusion that it is for /proc/acpi/event only. Add CONFIG_ACPI_PROC_EVENT to allow removal of /proc/acpi/event. There is no functional change if CONFIG_ACPI_PROC_EVENT=y Signed-off-by: Len Brown <len.brown@intel.com>
2007-08-23ACPI: don't duplicate input events on netlinkZhang Rui1-2/+1
The previous events patch added a netlink event for every user of the legacy /proc/acpi/event interface. However, some users of /proc/acpi/event are really input events, and they already report their events via the input layer. Introduce a new interface, acpi_bus_generate_netlink_event(), which is explicitly called by devices that want to repoprt events via netlink. This allows the input-like events to opt-out of generating netlink events. In summary: events that are sent via netlink: ac/battery/sbs thermal processor thinkpad_acpi dock/bay events that are sent via input layer: button video hotkey thinkpad_acpi hotkey asus_acpi/asus-laptop hotkey sonypi/sonylaptop Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2007-07-29Introduce CONFIG_SUSPEND for suspend-to-Ram and standbyRafael J. Wysocki1-0/+9
Introduce CONFIG_SUSPEND representing the ability to enter system sleep states, such as the ACPI S3 state, and allow the user to choose SUSPEND and HIBERNATION independently of each other. Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has been chosen and the kernel is intended for SMP systems. Also, introduce CONFIG_PM_SLEEP which is automatically selected if CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the code needed for both suspend and hibernation. The top-level power management headers and the ACPI code related to suspend and hibernation are modified to use the new definitions (the changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce the number of ifdefs). There are many other files in which CONFIG_PM can be replaced with CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in the future. Signed-off-by: Rafael J.

2007-01-05ACPI: use more understandable bus_id for ACPI devicesZhang Rui1-1/+1
Some of the ACPI devices use the internal fake hids which are exposed to userspace as devces' bus_id after sysfs conversion. To make it more friendly, we convert them to more understandable strings. For those devices w/o PNPids, we use "device:instance_no" as the bus_id instead of "PNPIDNON:instance_no".

2006-12-15ACPI: Set fake hid for non-PNPID ACPI devicesZhang Rui1-5/+1
We do this mainly because: 1. hid is used to match ACPI devices and drivers. .match method which is incompatible to driver model can be deleted from acpi_driver.ops then. 2. As the .uevent method mark ACPI drivers by PNPID, fake hid is set to non-PNPID devices so that udev script can load the right ACPI driver by looking for "HWID = " or "COMPTID = ".

2006-12-15ACPI: add acpi_bus_removal_type in acpi_deviceLi Shaohua1-0/+1
Add removal_type in structure acpi_device for hot removal. ACPI_BUS_REMOVAL_EJECT is used for ACPI device hot removal. Only one parameter is allowed in .remove method due to driver model. So removal_type is added to indicate different removal type. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2006-12-15ACPI: add acpi_bus_ops in acpi_deviceLi Shaohua1-0/+1
Add acpi_bus_ops in acpi_device to support acpi hot plug. NOTE: Two methods .add and .start in acpi_driver.ops are called separately to probe ACPI devices, while only .probe method is called in driver model. As executing .add and .start separately is critical for ACPI device hot plug, we use acpi_bus_ops to distinguish different code path.

2006-12-15ACPI: convert to sysfs frameworkPatrick Mochel1-1/+0

Operation on this file is exactly the same as before. i.e. echo 1 to "eject" will cause hot removal of this device. Corresponding changes should be made in userspace for hot removal.

Note: The new .uevent method mark ACPI drivers by PNPID instead of by name. Udev script needs to look for "HWID=" or "COMPTID=" to load ACPI drivers as a result.

2006-06-14ACPI: ACPICA 20060331Bob Moore1-1/+1
Implemented header file support for the following additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support, all current and known ACPI tables are now defined in the ACPICA headers and are available for use by device drivers and other software. Implemented support to allow tables that contain ACPI names with invalid characters to be loaded. Previously, this would cause the table load to fail, but since there are several known cases of such tables on existing machines, this change was made to enable ACPI support for them. Also, this matches the behavior of the Microsoft ACPI implementation. https://bugzilla.novell.com/show_bug.cgi?id=147621 Fixed a couple regressions introduced during the memory optimization in the 20060317 release. The namespace node definition required additional reorganization and an internal datatype that had been changed to 8-bit was restored to 32-bit. (Valery Podrezov) Fixed a problem where a null pointer passed to acpi_ut_delete_generic_state() could be passed through to acpi_os_release_object which is unexpected. Such null pointers are now trapped and ignored, matching the behavior of the previous implementation before the deployment of acpi_os_release_object(). (Valery Podrezov, Fiodor Suietov) Fixed a memory mapping leak during the deletion of a SystemMemory operation region where a cached memory mapping was not deleted. This became a noticeable problem for operation regions that are defined within frequently used control methods. (Dana Meyers) Reorganized the ACPI table header files into two main files: one for the ACPI tables consumed by the ACPICA core, and another for the miscellaneous ACPI tables that are consumed by the drivers and other software. The various FADT definitions were merged into one common section and three different tables (ACPI 1.0, 1.0+, and 2.0) Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2006-05-13ACPI: acpi_bus_unregister_driver() returns voidBjorn Helgaas1-1/+1
Nobody looks at the return value, and this brings it into line with pci_unregister_driver(), etc. Also removed validation of the driver pointer passed in to register and unregister. More consistent, and we'll find bugs faster if we fault rather than returning an error that's ignored. Also makes internal functions acpi_device_unregister() and acpi_driver_detach() void, since nobody uses their returns either.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+341
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
