Arjan van de Ven 0f66af5301 ACPI: battery: asynchronous init
The battery driver tends to take quite some time to initialize
(100ms-300ms is quite typical).
This patch initializes the batter driver asynchronously, so that other
things in the kernel can initialize in parallel to this 300 msec.

As part of this, the battery driver had to move to the back
of the ACPI init order (hence the Makefile change).
Without this move, the next ACPI driver would just block
on the ACPI/devicee layer semaphores until the battery driver was
done anyway, not gaining any boot time.

Rusty Russell 5b5d911740 ACPI: simplify module_param namespace
Impact: cleanup

Rather than overriding MODULE_PARAM_PREFIX, build via acpi.o so
KBUILD_MODNAME is set to "acpi".

This is the logical way to do it, even though acpi cannot be a module
due to these config options being bool.  Those parts of ACPI which can
be modular are not built into the acpi "module".

Bjorn Helgaas 018f452e9d ACPI: tidy up makefile
This patch removes the suggestion that ec.o link order is important,
because it doesn't matter since acpi_ec_init() is no longer an initcall.
And it puts together most of the core modules that are not configurable.

Remove CONFIG_ACPI_SYSTEM.  It was always set the same as CONFIG_ACPI,

Some things under CONFIG_ACPI_SYSTEM (acpi_irq_handled, acpi_os_gpe_count(),
event_is_open, register_acpi_notifier(), etc.) are used unconditionally
by the CA, the OSPM, and drivers, so we depend on them always being

Thomas Renninger c3d6de698c ACPI video: if no ACPI backlight support, use vendor drivers
If an ACPI graphics device supports backlight brightness functions (cmp. with
latest ACPI spec Appendix B), let the ACPI video driver control backlight and
switch backlight control off in vendor specific ACPI drivers (asus_acpi,
thinkpad_acpi, eeepc, fujitsu_laptop, msi_laptop, sony_laptop, acer-wmi).

Currently it is possible to load above drivers and let both poke on the
brightness HW registers, the video and vendor specific ACPI drivers -> bad.

This patch provides the basic support to check for BIOS capabilities before
driver loading time. Driver specific modifications are in separate follow up
patches.

"acpi_backlight=vendor"
	Prever vendor driver over ACPI driver for backlight.
"acpi_backlight=video" (default)
	Prever ACPI driver over vendor driver for backlight.

and it had no menu label, so there was no way to set it to anything

Per section 6.5.4 of the ACPI 3.0b specification,

    OSPM must make Embedded Controller operation regions, accessed
    via the Embedded Controllers described in ECDT, available before
    executing any control method.

The ECDT table is optional, but if it is present, the above text
means that the EC it describes is a required part of the ACPI
subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

Zhao Yakui 5eaff72218 ACPI: hack around sysfs warning with link order
There exists the following warning message will appear after the
following commit is merged.
   >commit f2e969acd6d5981e6b1272810002558650d0736e
   >Author: Zhao Yakui <yakui.zhao@intel.com>
   >Date:   Mon Aug 11 14:57:50 2008 +0800
    >ACPI: Add "acpi.power_nocheck=1" to disable power state check in
power transition:

   >WARNING: at linux-2.6/fs/sysfs/dir.c:463  sysfs_add_one+0x33/0x39()
   >sysfs: duplicate filename 'acpi' can not be created
   >kobject_add_internal failed for acpi with -EEXIST, don't try to register
            things with the same name in the same directory

   In the above commit the "acpi.power_nocheck" module parameter is defined
in drivers/acpi/power.c file. As several module parameters using the same ACPI
prefix are defined in the different files(for example: power_nocheck is
defined in drivers/acpi/power.c,debug_layer/debug_level are defined in
drivers/acpi/debug.c) and there exists another module between them, the
warning message will be printed when using the current generic param code.
(In the function of param_sysfs_init).

   In fact when ACPI is selected, the drivers/acpi/power will also be compiled
as built-in kernel.So this issue can be fixed by the following approach.
   workaround it by adjusting the module link order in drivers/acpi/Makefile.
In such case the module parameter using the same prefix(ACPI) are put together
in the param data section.

   Of course the better solution is to fix it in generic param code related
with sysfs.

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

David Shaohua Li 4e10d12a3d [ACPI] Bind PCI devices with ACPI devices
Implement the framework for binding physical devices
with ACPI devices. A physical bus like PCI bus
should create a 'acpi_bus_type', with:

.find_device:
        For device which has parent such as normal PCI devices.

.find_bridge:
        It's for special devices, such as PCI root bridge
	or IDE controller.  Such devices generally haven't a
	parent or ->bus. We use the special method
	to get an ACPI handle.

Uses new field in struct device: firmware_data

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
