Subject: [GIT PATCH] ACPI patches for 2.6.25-rc0
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
Hmmm, where to begin...
The standard platform specific driver updates, thinkpad, sony, asus
Thermal extensions to support Intel's new Menlo platform.
INITRAMFS DSDT override, a patch I resisted for years, but finally was convinced.
/sys/firmware/acpi/interrupts/ to see where your ACPI interrutps come from...
Initial WMI support -- Windows can run, but it can't hide...
video/brightness continues to mature...
cpuidle is now default enabled on ACPI configs
a bunch of bug fixes
This will update the files shown below.
thanks!
-Len
ps. individual patches are available on linux-acpi@...r.kernel.org
and a consolidated plain patch is available here:

ACPI: video: Ignore ACPI video devices that aren't present in hardware
Vendors often ship machines with a choice of integrated or discrete
graphics, and use the same DSDT for both. As a result, the ACPI video
module will locate devices that may not exist on this specific platform.
Attempt to determine whether the device exists or not, and abort the
device creation if it do not exist.

ACPI: video: create "brightness_switch_enabled" modparam
Introduce new module parameter for brightness control.
"brightness_switch_enabled" is set by default which means
nothing changes upon brightness switch events.
When "brightness_switch_enabled" is cleared via
"echo 0 > /sys/module/video/parameters/brightness_switch_enabled",
ACPI will not try to change the brightness level any more.
Either X will take charge of this or users can change the brightness level
by poking /sys/class/backlight/acpi_videoX/...

ACPI: idle: Fix acpi_safe_halt usages and interrupt enabling/disabling
acpi_safe_halt() needs interrupts to be disabled for atomic
need_resched check and safe halt. Otherwise we may miss an
interrupt and go into halt.
acpi_safe_halt() also does not enable interrupts on all return paths.
So the callers should handle enable and disable interrupts around it.

ACPI: track opregion names to avoid driver resource conflicts.
Small ACPICA extension to be able to store the name of operation regions in osl.c later
In ACPI, AML can define accesses to IO ports and System Memory by Operation
Regions. Those are not registered as done by PNPACPI using resource templates
(and _CRS/_SRS methods).
The IO ports and System Memory regions may get accessed by arbitrary AML code.
When native drivers are accessing the same resources bad things can happen
(e.g. a critical shutdown temperature of 3000 C every 2 months or so).
It is not really possible to register the operation regions via
request_resource, as they often overlap with pnp or other resources (e.g.
statically setup IO resources below 0x100).
This approach stores all Operation Region declarations (IO and System Memory
only) at ACPI table parse time. It offers a similar functionality like
request_region and let drivers which are known to possibly use the same IO
ports and Memory which are also often used by ACPI (hwmon and i2c) check for
ACPI interference.
A boot parameter acpi_enforce_resources=strict/lax/no is provided, which
is default set to lax:
- strict: let conflicting drivers fail to load with an error message
- lax: let conflicting driver work normal with a warning message
- no: no functional change at all
Depending on the feedback and the kind of interferences we see, this
should be set to strict at later time.
Goal of this patch set is:
- Identify ACPI interferences in bug reports (very hard to reproduce
and to identify)
- Find BIOSes for that an ACPI driver should exist for specific HW
instead of a native one.
- stability in general
Provide acpi_check_{mem_}region.
Drivers can additionally check against possible ACPI interference by also
invoking this shortly before they call request_region.
If -EBUSY is returned, the driver must not load.
Use acpi_enforce_resources=strict/lax/no options to:
- strict: let conflicting drivers fail to load with an error message
- lax: let conflicting driver work normal with a warning message
- no: no functional change at all

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)

ACPI: Update the t-state for every affected cpu when t-state is changed
According to ACPI spec, the _TSD object provides T-state control cross
logical processor dependency information to OSPM. So the t-state
coordination should be considered when T-state for one cpu is changed.
According to ACPI spec, three types of coordination are defined.
SW_ALL, SW_ANY and HW_ALL.
SW_ALL: it means that OSPM needs to initiate T-state transition on
all processors in the domain. It is necessary to call throttling set function
for all affected cpus.
SW_ANY: it means that OSPM may initiate T-state transition on any processor in
the domain.
HW_ALL: Spec only says that hardware will perform the coordination and doesn't
recommend how OSPM coordinate T-state among the affected cpus. So it is treated
as the type of SW_ALL. It means that OSPM needs to initiate t-state transition
on all the processors in the domain.

ACPI : Add T-state event notifier function
The t-state coordination should be considered when T-state for one cpu
is changed.It means that OSPM should select one proper target T-state for
the all affected cpus before updating T-state.
So the function of acpi_processor_throttling_notifier is added.
Before updating T-state it can be called for all the affected cpus to get
the proper target T-state, which can meet the requirement of thermal, user and
_TPC. After updating T-state, it can be called to update T-state flag.

ACPI : Update T-state coordination after getting _TSD info
Accordint to ACPI spec, the _TSD object provides T-state control cross
logical processor dependency information to OSPM.
After the _TSD data for all cpus are obtained, OSPM will set up
the T-state coordination between CPUs.
Of course if the _TSD doesn't exist or _TSD data is incorrect , it is
assumed that there is no T-state coordination and T-state is changed
independently.
Now there is no proper solution to update T-state coordination after
one cpu is hotplugged. So this patch won't support hotplugged cpu very well.

ACPI: register ACPI Processor as generic thermal cooling device
Register ACPI processor as thermal cooling devices.
A combination of processor T-state and P-state are used for thermal throttling.
the processor will reduce the frequency first and then set the T-state.
we use cpufreq_thermal_reduction_pctg to calculate the cpufreq limit,
and call cpufreq_verify_with_limit to set the cpufreq limit.
if cpufreq driver is loaded, then we have four cooling state for cpufreq control.
cooling state 0: cpufreq limit == max_freq
cooling state 1: cpufreq limit == max_freq * 80%
cooling state 2: cpufreq limit == max_freq * 60%
cooling state 3: cpufreq limit == max_freq * 40%
after the cpufreq limit is set to 40 percentage of the max_freq,
we use T-state for cooling.
eg. a processor has P-state support, and it has 8 T-state (T0-T7),
the max_state of the proceesor is 10:
state cpufreq-limit T-state
0: max_freq T0
1: max_freq * 80% T0
2: max_freq * 60% T0
3: max_freq * 40% T0
4: max_freq * 40% T1
5: max_freq * 40% T2
6: max_freq * 40% T3
7: max_freq * 40% T4
8: max_freq * 40% T5
9: max_freq * 40% T6

re-evaluate _PSV and _ACx methods upon notification 0x81
re-evaluate _PSL and _ALx and _TZD upon notificaiton 0x82.
But the current code re-evaluates all the trip points for 0x81 while
only re-evaluates _TZD for 0x82.
Fix this violation of ACPI spec.
TODO: devices in _PSL, _ALx and _TZD may change after a notification 0x82.

ACPI: thinkpad-acpi: wakeup on hotunplug reporting
Handle some HKEY events that the firmware uses to report the reason for a
wake up, and to also notify that the system could go back to sleep (if it
woke up just to eject something from the bay, or to undock).
The driver will report the reason of the last wake up in the sysfs
attribute "wakeup_reason": 0 for "none, unknown, or standard ACPI wake up
event", 1 for "bay ejection request" and 2 for "undock request".
The firmware will also report if the operation that triggered the wake up
has been completed, by issuing an HKEY 0x3003 or 0x4003 event. If the
operation fails, no event is sent. When such a hotunplug sucessfull
notification is issued, the driver sets the attribute
"wakeup_hotunplug_complete" to 1.
While the firmware does tell us whether we are waking from a suspend or
hibernation scenario, the Linux way of hibernating makes this information
not reliable, and therefore it is not reported.
The idea is that if any of these attributes are non-zero, userspace might
want to do something at the end of the "wake up from sleep" procedures,
such as offering to send the machine back into sleep as soon as it is safe
to do so.

ACPI: thinkpad-acpi: add CMOS NVRAM polling for hot keys (v9)
Older ThinkPad models do not export some of the hot keys over the
event-based ACPI hot key interface. For these models, one has to poll
the CMOS NVRAM to check the key state at a rate faster than the expected
rate at which the user might repeatedly press the same hot key.
This patch implements this functionality for many of the hotkeys in a
transparent way: hot keys will now Just Work, and the driver knows the
best approach (events or NVRAM polling) to employ, based on the
HKEY.MHKA ACPI method.
Also, the driver can turn off the polling when there are no users for
the hot keys that need such polling.
The NVRAM-based hot keys of the A3x series that have never been
implemented by later models are not supported, to avoid changes in the
keymap of the input devices that could cause headaches in the future.
There is a Kconfig option to avoid compiling the NVRAM polling code, as
it is not very small, and unlikely to be useful on any ThinkPad newer
than a T40, X31 or R52.
This feature is based on a previous effort by Richard Hughes.

ACPI: thinkpad-acpi: refactor hotkey_get and hotkey_set (v2)
Refactor and organize the code a bit for the NVRAM polling support:
1. Split hotkey_get/set into hotkey_status_get/set and hotkey_mask_get/set;
2. Cache the status of hot key mask for later driver use;
3. Make sure the cache of hot key mask is refreshed when needed;
4. log a printk notice when the firmware doesn't set the hot key
mask to exactly what we asked it to;
5. Add proper locking to the data structures.
Only (4) should be user-noticeable, but there is a chance (5) fixes
some unknown/unreported race conditions.

ACPI: thinkpad-acpi: document keymap gotcha's (v2)
Publish the requirements for keymap changes. This is a documentation

Currently, people look at the thinkpad-acpi default keymaps, and think:
"modifying this is a trivial thing, it can't break systems, and there are
keys defined for foo and bar, but the driver has them as KEY_RESERVED.
Must have been an oversight, let me change it."
And since they never get to see the bug reports, because they are not
really a part of the Linux ThinkPad users community (linux-thinkpad
mailinglist, thinkwiki wiki, thinkpad forums) and laptop users are slow
to complain to distros about any breakages...

ACPI: tables: complete searching upon RSDP w/ bad checksum.
ACPI tables follow a tree structure in memory.
The root of the tree is the RSDP (Root System Description Pointer).
To find the RSDP, the OS searches for the signature "RSD PTR "
in well known physical memory locations. Then the OS computes
a table checksum to verify that the signature is really part
of a valid table header.
Some systems have a proper signature but an invalid checksum;
followed elsewhere by a proper signature with valid checksum.
http://bugzilla.kernel.org/show_bug.cgi?id=9444
The Linux RSDP scanning code bailed out on those systems
and as a result they booted with ACPI disabled.
Fix this by deleting the Linux RSDP scanning code and
plugging in the ACPICA RSDP scanning code.

cpuidle: default processor.latency_factor=2
More aggressively request deep C-states.
Note that the job of the OS is to minimize latency
impact to expected break events such as interrupts.
It is not the job of the OS to try to calculate if
the C-state will reach energy break-even.
The platform doesn't give the OS enough information
for it to make that calculation. Thus, it is up
to the platform to decide if it is worth it to
go as deep as the OS requested it to, or if it
should internally demote to a more shallow C-state.
But the converse is not true. The platform can not
promote into a deeper C-state than the OS requested
else it may violate latency constraints. So it is
important that the OS be aggressive in giving the
platform permission to enter deep C-states.

Revert "speedstep-lib.c: fix frequency multiplier for Pentium4 models 0&1"
For P4 model < 2, The MSR_FBC_REGISTER_ID ratio is undefined.
Revert the commit that was added to handle that case,
as it results in random MHz displayed. Something else will
have to be done to properly handle model < 2.

// [PATCH] speedstep-lib.c: fix frequency multiplier for Pentium4 models 0&1
//
// The Pentium4 models 0&1 have a longer MSR_EBC_FREQUENCY_ID register as the
// models 2&3, so the bit shift must be bigger.

ACPI: disable stray GPE, prevent ACPI interrupt storm
GPEs are disabled depending on their type --
WAKE, WAKE_RUN, and RUNTIME. An error is returned
if we are asked to disable a GPE that has no type.
But at least one system exists that enables a GPE from AML
that is not the EC GPE, and has no _Lxx/_Exx AML handler,
and is thus never initialized.
In this case, when an external CRT is plugged in,
the GPE fires, we attempt to disable the GPE,
but instead just return an error.
So the GPE stays asserted and an ACPI interrupt storm follows.
The fix is to disable a firing GPE,
even if it comes from outer space.

ACPI: CONFIG_CPU_IDLE=ACPI by default
In Linux-2.6.24, CPU_IDLE went upstream, default =n.
For Linux-2.6.25, enable it by default on ACPI systems.
For Linux-2.6.26, we plan to enable it always on ACPI systems.

ACPI: add control method tracing support
Add debug tracing support during certain AML method execution.
Four more module parameters are created under /sys/module/acpi/parameters/:
trace_method_name: the AML method name that user wants to trace
trace_debug_layer: the temporary debug_layer used when tracing the method.
Using 0xffffffff by default if it is 0.
trace_debug_level: the temporary debug_level used when tracing the method.
Using 0x00ffffff by default if it is 0.
trace_state: The status of the tracing feature.
"enabled" means this feature is enabled
and the AML method is traced every time it's executed.
"1" means this feature is enabled and the AML method
will only be traced during the next execution.
"disabled" means this feature is disabled.
Users can enable/disable this debug tracing feature by
"echo string > /sys/module/acpi/parameters/trace_state".
"string" should be one of "enable", "disable" and "1".
