ACPI / driver core: Store an ACPI device pointer in struct acpi_dev_node
Modify struct acpi_dev_node to contain a pointer to struct acpi_device
associated with the given device object (that is, its ACPI companion
device) instead of an ACPI handle corresponding to it. Introduce two
new macros for manipulating that pointer in a CONFIG_ACPI-safe way,
ACPI_COMPANION() and ACPI_COMPANION_SET(), and rework the
ACPI_HANDLE() macro to take the above changes into account.
Drop the ACPI_HANDLE_SET() macro entirely and rework its users to
use ACPI_COMPANION_SET() instead. For some of them who used to
pass the result of acpi_get_child() directly to ACPI_HANDLE_SET()
introduce a helper routine acpi_preset_companion() doing an
equivalent thing.
The main motivation for doing this is that there are things
represented by struct acpi_device objects that don't have valid
ACPI handles (so called fixed ACPI hardware features, such as
power and sleep buttons) and we would like to create platform
device objects for them and "glue" them to their ACPI companions
in the usual way (which currently is impossible due to the
lack of valid ACPI handles). However, there are more reasons
why it may be useful.
First, struct acpi_device pointers allow of much better type checking
than void pointers which are ACPI handles, so it should be more
difficult to write buggy code using modified struct acpi_dev_node
and the new macros. Second, the change should help to reduce (over
time) the number of places in which the result of ACPI_HANDLE() is
passed to acpi_bus_get_device() in order to obtain a pointer to the
struct acpi_device associated with the given "physical" device,
because now that pointer is returned by ACPI_COMPANION() directly.
Finally, the change should make it easier to write generic code that
will build both for CONFIG_ACPI set and unset without adding explicit
compiler directives to it.

ACPI / PNP: use device ID list for PNPACPI device enumeration
ACPI can be used to enumerate PNP devices, but the code does not
handle this in the right way currently. Namely, if an ACPI device
object
1. Has a _CRS method,
2. Has an identification of
"three capital characters followed by four hex digits",
3. Is not in the excluded IDs list,
it will be enumerated to PNP bus (that is, a PNP device object will
be create for it). This means that, actually, the PNP bus type is
used as the default bus type for enumerating _HID devices in ACPI.
However, more and more _HID devices need to be enumerated to the
platform bus instead (that is, platform device objects need to be
created for them). As a result, the device ID list in acpi_platform.c
is used to enforce creating platform device objects rather than PNP
device objects for matching devices. That list has been continuously
growing recently, unfortunately, and it is pretty much guaranteed to
grow even more in the future.
To address that problem it is better to enumerate _HID devices
as platform devices by default. To this end, change the way of
enumerating PNP devices by adding a PNP ACPI scan handler that
will use a device ID list to create PNP devices for the ACPI
device objects whose device IDs are present in that list.
The initial device ID list in the PNP ACPI scan handler contains
all of the pnp_device_id strings from all the existing PNP drivers,
so this change should be transparent to the PNP core and all of the
PNP drivers. Still, in the future it should be possible to reduce
its size by converting PNP drivers that need not be PNP for any
technical reasons into platform drivers.

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

ACPI: Centralized processing of ACPI device resources
Currently, whoever wants to use ACPI device resources has to call
acpi_walk_resources() to browse the buffer returned by the _CRS
method for the given device and create filters passed to that
routine to apply to the individual resource items. This generally
is cumbersome, time-consuming and inefficient. Moreover, it may
be problematic if resource conflicts need to be resolved, because
the different users of _CRS will need to do that in a consistent
way. However, if there are resource conflicts, the ACPI core
should be able to resolve them centrally instead of relying on
various users of acpi_walk_resources() to handle them correctly
together.
For this reason, introduce a new function, acpi_dev_get_resources(),
that can be used by subsystems to obtain a list of struct resource
objects corresponding to the ACPI device resources returned by
_CRS and, if necessary, to apply additional preprocessing routine
to the ACPI resources before converting them to the struct resource
format.
Make the ACPI code that creates platform device objects use
acpi_dev_get_resources() for resource processing instead of executing
acpi_walk_resources() twice by itself, which causes it to be much
more straightforward and easier to follow.
In the future, acpi_dev_get_resources() can be extended to meet
the needs of the ACPI PNP subsystem and other users of _CRS in
the kernel.

ACPI: add module autoloading support for ACPI enumerated devices
An ACPI enumerated device may have its compatible id strings.
To support the compatible ACPI ids (acpi_device->pnp.ids),
we introduced acpi_driver_match_device() to match
the driver->acpi_match_table and acpi_device->pnp.ids.
For those drivers, MODULE_DEVICE_TABLE(acpi, xxx) is used to
exports the driver module alias in the format of
"acpi:device_compatible_ids".
But in the mean time, the current code does not export the
ACPI compatible strings as part of the module_alias for the
ACPI enumerated devices, which will break the module autoloading.
Take the following piece of code for example,
static const struct acpi_device_id xxx_acpi_match[] = {
{ "INTABCD", 0 },
{ }
};
MODULE_DEVICE_TABLE(acpi, xxx_acpi_match);
If this piece of code is used in a platform driver for
an ACPI enumerated platform device, the platform driver module_alias
is "acpi:INTABCD", but the uevent attribute of its platform device node
is "platform:INTABCD:00" (PREFIX:platform_device->name).
If this piece of code is used in an i2c driver for an ACPI enumerated
i2c device, the i2c driver module_alias is "acpi:INTABCD", but
the uevent of its i2c device node is "i2c:INTABCD:00" (PREFIX:i2c_client->name).
If this piece of code is used in an spi driver for an ACPI enumerated
spi device, the spi driver module_alias is "acpi:INTABCD", but
the uevent of its spi device node is "spi:INTABCD" (PREFIX:spi_device->modalias).
The reason why the module autoloading is not broken for now is that
the uevent file of the ACPI device node is "acpi:INTABCD".
Thus it is the ACPI device node creation that loads the platform/i2c/spi driver.
So this is a problem that will affect us the day when the ACPI bus
is removed from device model.
This patch introduces two new APIs,
one for exporting ACPI ids in uevent MODALIAS field,
and another for exporting ACPI ids in device' modalias sysfs attribute.
For any bus that supports ACPI enumerated devices, it needs to invoke
these two functions for their uevent and modalias attribute.

ACPI / driver core: Store an ACPI device pointer in struct acpi_dev_node
Modify struct acpi_dev_node to contain a pointer to struct acpi_device
associated with the given device object (that is, its ACPI companion
device) instead of an ACPI handle corresponding to it. Introduce two
new macros for manipulating that pointer in a CONFIG_ACPI-safe way,
ACPI_COMPANION() and ACPI_COMPANION_SET(), and rework the
ACPI_HANDLE() macro to take the above changes into account.
Drop the ACPI_HANDLE_SET() macro entirely and rework its users to
use ACPI_COMPANION_SET() instead. For some of them who used to
pass the result of acpi_get_child() directly to ACPI_HANDLE_SET()
introduce a helper routine acpi_preset_companion() doing an
equivalent thing.
The main motivation for doing this is that there are things
represented by struct acpi_device objects that don't have valid
ACPI handles (so called fixed ACPI hardware features, such as
power and sleep buttons) and we would like to create platform
device objects for them and "glue" them to their ACPI companions
in the usual way (which currently is impossible due to the
lack of valid ACPI handles). However, there are more reasons
why it may be useful.
First, struct acpi_device pointers allow of much better type checking
than void pointers which are ACPI handles, so it should be more
difficult to write buggy code using modified struct acpi_dev_node
and the new macros. Second, the change should help to reduce (over
time) the number of places in which the result of ACPI_HANDLE() is
passed to acpi_bus_get_device() in order to obtain a pointer to the
struct acpi_device associated with the given "physical" device,
because now that pointer is returned by ACPI_COMPANION() directly.
Finally, the change should make it easier to write generic code that
will build both for CONFIG_ACPI set and unset without adding explicit
compiler directives to it.

ACPI / PM: Provide ACPI PM callback routines for subsystems
Some bus types don't support power management natively, but generally
there may be device nodes in ACPI tables corresponding to the devices
whose bus types they are (under ACPI 5 those bus types may be SPI,
I2C and platform). If that is the case, standard ACPI power
management may be applied to those devices, although currently the
kernel has no means for that.
For this reason, provide a set of routines that may be used as power
management callbacks for such devices. This may be done in three
different ways.
(1) Device drivers handling the devices in question may run
acpi_dev_pm_attach() in their .probe() routines, which (on
success) will cause the devices to be added to the general ACPI
PM domain and ACPI power management will be used for them going
forward. Then, acpi_dev_pm_detach() may be used to remove the
devices from the general ACPI PM domain if ACPI power management
is not necessary for them any more.
(2) The devices' subsystems may use acpi_subsys_runtime_suspend(),
acpi_subsys_runtime_resume(), acpi_subsys_prepare(),
acpi_subsys_suspend_late(), acpi_subsys_resume_early() as their
power management callbacks in the same way as the general ACPI
PM domain does that.
(3) The devices' drivers may execute acpi_dev_suspend_late(),
acpi_dev_resume_early(), acpi_dev_runtime_suspend(),
acpi_dev_runtime_resume() from their power management callbacks
as appropriate, if that's absolutely necessary, but it is not
recommended to do that, because such drivers may not work
without ACPI support as a result.

ACPI / PM: Provide ACPI PM callback routines for subsystems
Some bus types don't support power management natively, but generally
there may be device nodes in ACPI tables corresponding to the devices
whose bus types they are (under ACPI 5 those bus types may be SPI,
I2C and platform). If that is the case, standard ACPI power
management may be applied to those devices, although currently the
kernel has no means for that.
For this reason, provide a set of routines that may be used as power
management callbacks for such devices. This may be done in three
different ways.
(1) Device drivers handling the devices in question may run
acpi_dev_pm_attach() in their .probe() routines, which (on
success) will cause the devices to be added to the general ACPI
PM domain and ACPI power management will be used for them going
forward. Then, acpi_dev_pm_detach() may be used to remove the
devices from the general ACPI PM domain if ACPI power management
is not necessary for them any more.
(2) The devices' subsystems may use acpi_subsys_runtime_suspend(),
acpi_subsys_runtime_resume(), acpi_subsys_prepare(),
acpi_subsys_suspend_late(), acpi_subsys_resume_early() as their
power management callbacks in the same way as the general ACPI
PM domain does that.
(3) The devices' drivers may execute acpi_dev_suspend_late(),
acpi_dev_resume_early(), acpi_dev_runtime_suspend(),
acpi_dev_runtime_resume() from their power management callbacks
as appropriate, if that's absolutely necessary, but it is not
recommended to do that, because such drivers may not work
without ACPI support as a result.

ACPI: Add acpi_handle_<level>() interfaces
This patch introduces acpi_handle_<level>(), where <level> is
a kernel message level such as err/warn/info, to support improved
logging messages for ACPI, esp. hot-plug operations.
acpi_handle_<level>() appends "ACPI" prefix and ACPI object path
to the messages. This improves diagnosis of hotplug operations
since an error message in a log file identifies an object that
caused an issue. This interface acquires the global namespace
mutex to obtain an object path. In interrupt context, it shows
the object path as <n/a>.
acpi_handle_<level>() takes acpi_handle as an argument, which is
passed to ACPI hotplug notify handlers from the ACPICA. Therefore,
it is always available unlike other kernel objects, such as device.
For example:
acpi_handle_err(handle, "Device don't exist, dropping EJECT\n");
logs an error message like this at KERN_ERR.
ACPI: \_SB_.SCK4.CPU4: Device don't exist, dropping EJECT
ACPI hot-plug drivers can use acpi_handle_<level>() when they need
to identify a target ACPI object path in their messages, such as
error cases. The usage model is similar to dev_<level>().
acpi_handle_<level>() can be used when a device is not created or
is invalid during hot-plug operations. ACPI object path is also
consistent on the platform, unlike device name that gets incremented
over hotplug operations.
ACPI drivers should use dev_<level>() when a device object is valid.
Device name provides more user friendly information, and avoids
acquiring the global ACPI namespace mutex. ACPI drivers also
continue to use pr_<level>() when they do not need to specify device
information, such as boot-up messages.
Note: ACPI_[WARNING|INFO|ERROR]() are intended for the ACPICA and
are not associated with the kernel message level.

ACPI: Add acpi_handle_<level>() interfaces
This patch introduces acpi_handle_<level>(), where <level> is
a kernel message level such as err/warn/info, to support improved
logging messages for ACPI, esp. hot-plug operations.
acpi_handle_<level>() appends "ACPI" prefix and ACPI object path
to the messages. This improves diagnosis of hotplug operations
since an error message in a log file identifies an object that
caused an issue. This interface acquires the global namespace
mutex to obtain an object path. In interrupt context, it shows
the object path as <n/a>.
acpi_handle_<level>() takes acpi_handle as an argument, which is
passed to ACPI hotplug notify handlers from the ACPICA. Therefore,
it is always available unlike other kernel objects, such as device.
For example:
acpi_handle_err(handle, "Device don't exist, dropping EJECT\n");
logs an error message like this at KERN_ERR.
ACPI: \_SB_.SCK4.CPU4: Device don't exist, dropping EJECT
ACPI hot-plug drivers can use acpi_handle_<level>() when they need
to identify a target ACPI object path in their messages, such as
error cases. The usage model is similar to dev_<level>().
acpi_handle_<level>() can be used when a device is not created or
is invalid during hot-plug operations. ACPI object path is also
consistent on the platform, unlike device name that gets incremented
over hotplug operations.
ACPI drivers should use dev_<level>() when a device object is valid.
Device name provides more user friendly information, and avoids
acquiring the global ACPI namespace mutex. ACPI drivers also
continue to use pr_<level>() when they do not need to specify device
information, such as boot-up messages.
Note: ACPI_[WARNING|INFO|ERROR]() are intended for the ACPICA and
are not associated with the kernel message level.
