There is no way to interact with a physical PCI slot without
sysfs, so encode the dependency and prevent this build error:drivers/pci/slot.c: In function 'pci_hp_create_module_link':
drivers/pci/slot.c:327: error: 'module_kset' undeclaredThis patch _should_ make pci-sysfs.o depend on CONFIG_SYSFS too,
but we cannot (yet) because the PCI core merrily assumes the
existence of sysfs:drivers/built-in.o: In function `pci_bus_add_device':
drivers/pci/bus.c:89: undefined reference to `pci_create_sysfs_dev_files'
drivers/built-in.o: In function `pci_stop_dev':
drivers/pci/remove.c:24: undefined reference to `pci_remove_sysfs_dev_files'So do the minimal bit for now and figure out how to untangle it
later.Reported-by: Randy Dunlap

ACPI can't be a module, so if both ACPI & APM are configured,
we use ACPI.Update pointers to ACPI CA and Linux ACPI projects.

Remove CONFIG_ACPI_SYSTEM. It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".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

Remove CONFIG_ACPI_EC. It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".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.Signed-off-by: Bjorn Helgaas

Initially CONFIG_PM_SLEEP was defined as
CONFIG_SUSPEND || CONFIG_HIBERNATION and some ACPI code, most
importantly the code in drivers/acpi/main.c, was written with this
assumption. Currently, however, CONFIG_PM_SLEEP is also set when
CONFIG_XEN_SAVE_RESTORE is set.This causes some compilation warnings to appear in
drivers/acpi/main.c if both CONFIG_SUSPEND and CONFIG_HIBERNATION
are unset and CONFIG_PM_SLEEP is set (this was impossible before).
To fix this problem, redefine CONFIG_ACPI_SLEEP do depend directly
on CONFIG_SUSPEND || CONFIG_HIBERNATION, as originally intended, and
use it instead of CONFIG_PM_SLEEP in drivers/acpi/main.c, wherever
appropriate.Additionally, move the acpi_target_sleep_state definition from under
the #ifdef to prevent compilation from failing in some cases.Signed-off-by: Rafael J. Wysocki

There's been a patch floating around for toshiba_acpi that exports an ad-hoc
/proc interface to toggle the bluetooth adapter in a large number of Toshiba
laptops. I'm not sure if it's still relevant for the latest models, but it is
still required for older models such as my Tecra M3.This change pulls in the low level Toshiba-specific code from the old patch and
sets up an rfkill device and a polled input device to track the state of the

This essentially reverts commit 71fc47a9adf8ee89e5c96a47222915c5485ac437
("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.Cc: Dave Hansen

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 codev3 (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 handlingv5 (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 addressv8 (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 fixesv10 (2007-12-12)
* Workaround broken GUIDs declared expensive without a WCxx method.
* Minor cleanupsv11 (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 KconfigSigned-off-by: Carlos Corbacho

/sys/class/thermal:
|thermal_zone1:
|-----type: "ACPI thermal zone". RO
|-----temp: the current temperature. RO
|-----mode: the current working mode. RW.
the default value is "kernel" which means thermal
management is done by ACPI thermal driver.
"echo user > mode" prevents all the ACPI thermal driver
actions upon any trip points.
|-----trip_point_0_temp: the threshold of trip point 0. RO.
|-----trip_point_0_type: "critical". RO.
the type of trip point 0
This may be one of critical/hot/passive/active[x]
