Alex Chiang 8344b568f5 PCI: ACPI PCI slot detection driver
Detect all physical PCI slots as described by ACPI, and create entries in
/sys/bus/pci/slots/.

Not all physical slots are hotpluggable, and the acpiphp module does not
detect them.  Now we know the physical PCI geography of our system, without
caring about hotplug.

Linus Torvalds 9a9e0d6855 ACPI: Remove ACPI_CUSTOM_DSDT_INITRD option
This essentially reverts commit 71fc47a9ad
("ACPI: basic initramfs DSDT override support"), because the code simply
isn't ready.

It did ugly things to the init sequence to populate the rootfs image
early, but that just ended up showing other problems with the whole
approach.  The fact is, the VFS layer simply isn't initialized this
early, and the relevant ACPI code should either run much later, or this
shouldn't be done at all.

For 2.6.25, we'll just pick the latter option.  We can revisit this
concept later if necessary.

The basics of DSDT from initramfs. In case this option is selected,
populate_rootfs() is called a bit earlier to have the initramfs content
available during ACPI initialization.

This is a very similar path to the one available at
http://gaugusch.at/kernel.shtml but with some update in the
documentation, default set to No and the change of populate_rootfs() the
"Jeff Mahony way" (which avoids reading the initramfs twice).

Carlos Corbacho bff431e49f ACPI: WMI: Add ACPI-WMI mapping driver
The following is an implementation of the Windows Management
Instrumentation (WMI) ACPI interface mapper (PNP0C14).

What it does:

Parses the _WDG method and exports functions to process WMI method calls,
data block query/ set commands (both based on GUID) and does basic event
handling.

How: WMI presents an in kernel interface here (essentially, a minimal
wrapper around ACPI)

(const char *guid assume the 36 character ASCII representation of
a GUID - e.g. 67C3371D-95A3-4C37-BB61-DD47B491DAAB)

wmi_evaluate_method(const char *guid, u8 instance, u32 method_id,
const struct acpi_buffer *in, struct acpi_buffer *out)

wmi_query_block(const char *guid, u8 instance,
struct acpi_buffer *out)

wmi_set_block(const char *guid, u38 instance,
const struct acpi_buffer *in)

wmi_install_notify_handler(acpi_notify_handler handler);

wmi_remove_notify_handler(void);

wmi_get_event_data(u32 event, struct acpi_buffer *out)

wmi_has_guid(const char guid*)

wmi_has_guid() is a helper function to find if a GUID exists or not on the
system (a quick and easy way for WMI dependant drivers to see if the
the method/ block they want exists, since GUIDs are supposed to be unique).

Event handling - allow a WMI based driver to register a notifier handler
for each GUID with WMI. When a notification is sent to a GUID in WMI, the
handler registered with WMI is then called (it is left to the caller to
ask for the WMI event data associated with the GUID, if needed).

What it won't do:

Unicode - The MS article[1] calls for converting between ASCII and Unicode (or
vice versa) if a GUID is marked as "string". This is left up to the calling
driver.

Handle a MOF[1] - the WMI mapper just exports methods, data and events to
userspace. MOF handling is down to userspace.

Userspace interface - this will be added later.

ChangeLog
==

v1 (2007-10-02):

* Initial release

v2 (2007-10-05):

* Cleaned up code - split up super "wmi_evaluate_block" -> each external
  symbol now handles its own ACPI calls, rather than handing off to
  a "super" method (and in turn, is a lot simpler to read)
* Added a find_guid() symbol - return true if a given GUID exists on
  the system
* wmi_* functions now return type acpi_status (since they are just
  fancy wrappers around acpi_evaluate_object())
* Removed extra debug code

v3 (2007-10-27)

* More code clean up - now passes checkpatch.pl
* Change data block calls - ref MS spec, method ID is not required for
  them, so drop it from the function parameters.
* Const'ify guid in the function call parameters.
* Fix _WDG buffer handling - copy the data to our own private structure.
* Change WMI from tristate to bool - otherwise the external functions are
  not exported in linux/acpi.h if you try to build WMI as a module.
* Fix more flag comparisons.
* Add a maintainers entry - since I wrote this, I should take the blame
  for it.

v4 (2007-10-30)

* Add missing brace from after fixing checkpatch errors.
* Rewrote event handling - allow external drivers to register with WMI to
  handle WMI events
* Clean up flags and sanitise flag handling

v5 (2007-11-03)

* Add sysfs interface for userspace. Export events over netlink again.
* Remove module left overs, fully convert to built-in driver.
* Tweak in-kernel API to use u8 for instance, since this is what the GUID
  blocks use (so instance cannot be greater than u8).
* Export wmi_get_event_data() for in kernel WMI drivers.

v6 (2007-11-07)

* Split out userspace into a different patch

v7 (2007-11-20)

* Fix driver to handle multiple PNP0C14 devices - store all GUIDs using
  the kernel's built in list functions, and just keep adding to the list
  every time we handle a PNP0C14 devices - GUIDs will always be unique,
  and WMI callers do not know or care about different devices.
* Change WMI event handler registration to use its' own event handling
  struct; we should not pass an acpi_handle down to any WMI based drivers
  - they should be able to function with only the calls provided in WMI.
* Update my e-mail address

v8 (2007-11-28)

* Convert back to a module.
* Update Kconfig to default to building as a module.
* Remove an erroneous printk.
* Simply comments for string flag (since we now leave the handling to the
  caller).

v9 (2007-12-07)

* Add back missing MODULE_DEVICE_TABLE for autoloading
* Checkpatch fixes

v10 (2007-12-12)

* Workaround broken GUIDs declared expensive without a WCxx method.
* Minor cleanups

v11 (2007-12-17)

* More fixing for broken GUIDs declared expensive without a WCxx method.
* Add basic EmbeddedControl region handling.

v12 (2007-12-18)

* Changed EC region handling code, as per Alexey's comments.

v13 (2007-12-27)

* Changed event handling so that we can have one event handler registered
  per GUID, as per Matthew Garrett's suggestion.

v14 (2008-01-12)

* Remove ACPI debug statements

v15 (2008-02-01)

* Replace two remaining 'x == NULL' type tests with '!x'

v16 (2008-02-05)

* Change MAINTAINERS entry, as I am not, and never have been, paid to work
  on WMI
* Remove 'default' line from Kconfig

Rafael J. Wysocki 296699de6b Introduce CONFIG_SUSPEND for suspend-to-Ram and standby
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.

Len Brown e8b2fd0122 ACPI: Kconfig: remove CONFIG_ACPI_SLEEP from source
As it was a synonym for (CONFIG_ACPI && CONFIG_X86),
the ifdefs for it were more clutter than they were worth.

For ia64, just add a few stubs in anticipation of future
S3 or S4 support.

Len Brown 7c5aa6642f ACPI: Kconfig: always enable CONFIG_ACPI_SLEEP on X86
The SMP dependency on HOTPLUG_CPU and SUSPEND_SMP
caused more harm than good -- making ACPI sleep
support vanish for configs missing those options.
So simply select them on the (ACPI && SMP && X86) systems
that need them.

Also, remove the prompt for ACPI_SLEEP,
virtually nobody (intentionally) enables ACPI without it.

Len Brown 43532c8a46 ACPI: Kconfig: fold /proc/acpi/sleep under CONFIG_ACPI_PROCFS
/proc/acpi/sleep has had its own "default n" option,
ACPI_SLEEP_PROC_SLEEP, for many months.
Time to delete ACPI_SLEEP_PROC_SLEEP.

Users that still need /proc/acpi/sleep can still get it
along with the other deprecated /proc/acpi files
by enabling CONFIG_ACPI_PROCFS.

Also delete ACPI_SLEEP_PROC_FS, which was an umbrella
for /proc/acpi/sleep, wakeup, alarm, because it was
effectively just a synonym for ACPI_SLEEP.

Len Brown fb80471456 ACPI: Kconfig: CONFIG_ACPI_PROCFS now defaults to N
delete "default y" from CONFIG_ACPI_PROCFS
(effectively making the default 'N')

List exactly what /proc files this option controls,
and clarify that it doesn't change non-deprecated files.

Thomas Renninger 798d910398 ACPI: create CONFIG_ACPI_DEBUG_FUNC_TRACE
Split ACPI_DEBUG into function trace enabled and not enabled.

Function trace is most of the ACPI_DEBUG costs, but is
not much of use for kernel ACPI debugging.

Size of kernel image increased on test compile:
+ 48k  (Full ACPI_DEBUG)
+ 35k  (ACPI_DEBUG with function trace compiled out)

Performance without function trace is also much better.

Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
a lot vendors let Store (value, debug) in their code and this
might confuse users when it pops up in syslog.

Luming Yu 23b0f015bf ACPI: video: output switch sysfs support
Requires CONFIG_VIDEO_OUTPUT_CONTROL and CONFIG_ACPI_VIDEO.

After loading output.ko and video.ko, you would have
/sys/class/video_output and several device acpi_videoNum there.

For example, I got acpi_video0, acpi_video1,acpi_video2,and acpi_video3
under /sys/class/video_output on my T40.
I can query the status of  output device0 by running " cat
/sys/class/video_output/acpi_video0
" The return value is defined in ACPI SPEC B.5.5 _DCS(Return the
Status of Output Device).  Also you can turn off video1 and turn on
video0  by " echo 0 > acpi_video1; echo 0x80000000 > acpi_video0".
Please reference ACPI SPEC  B.5.7 _DSS for the parameter definition.

Please note that it may or may NOT works purely depending on if
your vendor providing correct ACPI video extension support in bios.
the driver output.ko and video.ko just works like a interface to
invoke BIOS.
