ACPI: processor: use .notify method instead of installing handler directly
This patch adds a .notify() method. The presence of .notify() causes
Linux/ACPI to manage event handlers and notify handlers on our behalf,
so we don't have to install and remove them ourselves.

ACPI: button: use .notify method instead of installing handler directly
This patch adds a .notify() method. The presence of .notify() causes
Linux/ACPI to manage event handlers and notify handlers on our behalf,
so we don't have to install and remove them ourselves.
Note that events from fixed hardware buttons now show up as a special
notify event, so to preserve user-space backward compatibility, we
convert that back to ACPI_BUTTON_NOTIFY_STATUS.

ACPI: support acpi_device_ops .notify methods
This patch adds support for ACPI device driver .notify() methods. If
such a method is present, Linux/ACPI installs a handler for device
notifications (but not for system notifications such as Bus Check,
Device Check, etc). When a device notification occurs, Linux/ACPI
passes it on to the driver's .notify() method.
In most cases, this removes the need for drivers to install their own
handlers for device-specific notifications.
For fixed hardware devices like some power and sleep buttons, there's
no notification value because there's no control method to execute a
Notify opcode. When a fixed hardware device generates an event, we
handle it the same as a regular device notification, except we send
a ACPI_FIXED_HARDWARE_EVENT value. This is outside the normal 0x0-0xff
range used by Notify opcodes.
Several drivers install their own handlers for system Bus Check and
Device Check notifications so they can support hot-plug. This patch
doesn't affect that usage.

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.

acer-wmi: Blacklist Acer Aspire One
The Aspire One's ACPI-WMI interface is a placeholder that does nothing,
and the invalid results that we get from it are now causing userspace
problems as acer-wmi always returns that the rfkill is enabled (i.e. the
radio is off, when it isn't). As it's hardware controlled, acer-wmi
isn't needed on the Aspire One either.

thinkpad-acpi: rework brightness support
Refactor and redesign the brightness control backend...
In order to fix bugzilla #11750...
Add a new brightness control mode: support direct NVRAM checkpointing
of the backlight level (i.e. store directly to NVRAM without the need
for UCMS calls), and use that together with the EC-based control.
Disallow UCMS+EC, thus avoiding races with the SMM firmware.
Switch the models that define HBRV (EC Brightness Value) in the DSDT
to the new mode. These are: T40-T43, R50-R52, R50e, R51e, X31-X41.
Change the default for all other IBM ThinkPads to UCMS-only. The
Lenovo models already default to UCMS-only.

thinkpad-acpi: restrict access to some firmware LEDs
Some of the ThinkPad LEDs indicate critical conditions that can cause
data loss or cause hardware damage when ignored (e.g. force-ejecting
a powered up bay; ignoring a failing battery, or empty battery; force-
undocking with the dock buses still active, etc).
On almost all ThinkPads, LED access is write-only, and the firmware
usually does fire-and-forget signaling on them, so you effectively
lose whatever message the firmware was trying to convey to the user
when you override the LED state, without any chance to restore it.
Restrict access to all LEDs that can convey important alarms, or that
could mislead the user into incorrectly operating the hardware. This
will make the Lenovo engineers less unhappy about the whole issue.
Allow users that really want it to still control all LEDs, it is the
unaware user that we have to worry about.

thinkpad-acpi: remove HKEY disable functionality
The HKEY disable functionality basically cripples the entire event
model of the ThinkPad firmware and of the thinkpad-acpi driver.
Remove this functionality from the driver. HKEY must be enabled at
all times while thinkpad-acpi is loaded, and disabled otherwise.
For sysfs, according to the sysfs ABI and the thinkpad-acpi sysfs
rules of engagement, we will just remove the attributes. This will be
done in two stages: disable their function now, after two kernel
releases, remove the attributes.
For procfs, we call WARN(). If nothing triggers it, I will simply
remove the enable/disable commands entirely in the future along with
the sysfs attributes.
I don't expect much, if any fallout from this. There really isn't any
reason to mess with hotkey_enable or with the enable/disable commands
to /proc/acpi/ibm/hotkey, and this has been true for years...

dell-wmi: new driver for hotkey control
Add a WMI driver for Dell laptops. Currently it does nothing but send a

pressed, but maybe other uses will appear over time.

Enable PNPACPI _PSx Support, v3
(This is an update to the patch presented earlier in
http://lkml.org/lkml/2008/12/8/284, with new error handling.)
This patch sets the power of PnP ACPI devices to D0 when they
are activated and to D3 when they are disabled. The latter is
in correspondence with the ACPI 3.0 specification, whereas the
former is added in order to be able to power up a device after
it has been previously disabled (or when booting up a system).
(As a consequence, the patch makes the PnP ACPI code more ACPI
compliant.)
Section 6.2.2 of the ACPI Specification (at least versions 1.0b
and 3.0a) states: "Prior to running this control method [_DIS],
the OS[PM] will have already put the device in the D3 state."
Unfortunately, there is no clear statement as to when to put
a device in the D0 state. :-( Therefore, the patch executes the
method calls as _PS3/_DIS and _SRS/_PS0. What is clear: "If the
device is disabled, _SRS enables the device at the specified
resources." (From the ACPI 3.0a Specification.)
The patch fixes a problem with some IBM ThinkPads (at least the
600E and the 600X) where the serial ports have a dedicated
power source that needs to be brought up before the serial port
can be used. Without this patch, the serial port is enabled
but has no power. (In the past, the tpctl utility had to be
utilized to turn on the power, but support for this feature
stopped with version 5.9 as it did not support the more recent
kernel versions.)
The error handlers that handle any errors that can occur during
the power up/power down phases return the error codes to the
caller directly. Comments welcome! :-)
No regressions were observed on hardware that does not require
this patch.
The patch is applied against 2.6.27.x.

x86, ACPI: add support for x2apic ACPI extensions
All logical processors with APIC ID values of 255 and greater will have their
APIC reported through Processor X2APIC structure (type-9 entry type) and all
logical processors with APIC ID less than 255 will have their APIC reported
through legacy Processor Local APIC (type-0 entry type) only. This is the
same case even for NMI structure reporting.
The Processor X2APIC Affinity structure provides the association between the
X2APIC ID of a logical processor and the proximity domain to which the logical
processor belongs.
For OSPM, Procssor IDs outside the 0-254 range are to be declared as Device()
objects in the ACPI namespace.

tc1100-wmi: Fix state reporting
The tc1100-wmi driver should print the current states of wireless LAN and
jogdial brightness control when "cat /sys/devices/platform/tc1100-wmi/wireless"
and "cat /sys/devices/platform/tc1100-wmi/jogdial" are executed, respectively.
What actually happens is that both of those commands print 0 regardless of the
hardware state. The cause is that wmi_query_block returns an ACPI_TYPE_INTEGER
rather than ACPI_TYPE_BUFFER as the driver assumes. Additionally, the driver
intends to return a jogdial state that is inverted with respect to the commands
required to set it (e.g. it intends to return 1 after the jogdial file was
written with 0).
This patch fixes both of those issues - the commands to query the
state now work, and should return the same state that was written.

ACPI video: support _BCL packages that don't export brightness levels when machine is on AC/Battery
Many buggy BIOSes don't export the brightness levels when machine
is on AC/Battery in the _BCL method.
Reformat the _BCL package for these laptops:
now the elements in device->brightness->levels[] are like:
levels[0]: brightness level when on AC power.
levels[1]: brightness level when on Battery power.
levels[2]: supported brightness level 1.
levels[3]: supported brightness level 2.
...
levels[n]: supported brightness level n-1.
levels[n + 1]: supported brightness level n.
So if there are n supported brightness levels on this laptop,
we will have n+2 entries in device->brightnes->levels[].
level[0] and level[1] are invalid on the laptops that don't
export the brightness levels on AC/Battery.
Fortunately, we never use these two values at all, even for the
valid ones.

ACPI: cap off P-state transition latency from buggy BIOSes
Some BIOSes report very high frequency transition latency which are plainly
wrong on CPus that can change frequency using native MSR interface.
One such system is IBM T42 (2327-8ZU) as reported by Owen Taylor and
Rik van Riel.
cpufreq_ondemand driver uses this transition latency to come up with a
reasonable sampling interval to sample CPU usage and with such high
latency value, ondemand sampling interval ends up being very high
(0.5 sec, in this particular case), resulting in performance impact due to
slow response to increasing frequency.
Fix it by capping-off the transition latency to 20uS for native MSR based
frequency transitions.

thermal: support forcing support for passive cooling
Due to poor thermal design or Linux driving hardware outside its thermal
envelope, some systems will reach critical temperature and shut down
under high load. This patch adds support for forcing a polling-based
passive trip point if the firmware doesn't provide one. The assumption
is made that the processor is the most practical means to reduce the
dynamic heat generation, so hitting the passive thermal limit will cause
the CPU to be throttled until the temperature stabalises around the
defined value.
UI is provided via a "passive" sysfs entry in the thermal zone
directory. It accepts a decimal value in millidegrees celsius, or "0" to
disable the functionality. Default behaviour is for this functionality
to be disabled.

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.

ACPI: call acpi_wakeup_device_init() explicitly rather than as initcall
This patch makes acpi_init() call acpi_wakeup_device_init() directly.
Previously, acpi_wakeup_device_init() was a late_initcall (sequence 7).
acpi_wakeup_device_init() depends on acpi_wakeup_device_list, which
is populated when ACPI devices are enumerated by acpi_init() ->
acpi_scan_init(). Using late_initcall is certainly enough to make
sure acpi_wakeup_device_list is populated, but it is more than
necessary. We can just as easily call acpi_wakeup_device_init()
directly from acpi_init(), which avoids the initcall magic.

ACPI: call acpi_sleep_proc_init() explicitly rather than as initcall
This patch makes acpi_init() call acpi_sleep_proc_init() directly.
Previously, acpi_sleep_proc_init() was a late_initcall (sequence 7),
apparently to make sure that the /proc hierarchy already exists:
2003/02/13 12:38:03-06:00 mochel
acpi sleep: demote sleep proc file creation.
- Make acpi_sleep_proc_init() a late_initcall(), and not called from
acpi_sleep_init(). This guarantees that the acpi proc hierarchy is at
least there when we create the dang file.
This should no longer be an issue because acpi_bus_init() (called early
in acpi_init()) creates acpi_root_dir (/proc/acpi).

ACPI: call init_acpi_device_notify() explicitly rather than as initcall
This patch makes acpi_init() call init_acpi_device_notify() directly.
Previously, init_acpi_device_notify() was an arch_initcall (sequence 3),
so it was called before acpi_init() (a subsys_initcall at sequence 4).
init_acpi_device_notify() sets the platform_notify and
platform_notify_remove function pointers. These pointers
are not used until acpi_init() enumerates ACPI devices in
this path:
acpi_init()
acpi_scan_init()
acpi_bus_scan()
acpi_add_single_object()
acpi_device_register()
device_add()
<use platform_notify>
So it is sufficient to have acpi_init() call init_acpi_device_notify()
directly before it enumerates devices.

Use the 32-bit register addresses whenever they are non-zero. This
means that the 32-bit addresses are favored over the 64-bit
(GAS) addresses. The 64-bit addresses are only used if the 32-bit
addresses are zero. This change provides compatibility with all
versions of Windows. The worst case that this solves is when both
the 32-bit and 64-bit addresses are non-zero, but only the 32-bit
addresses are actually valid. This appears to happen in some
BIOSes because in this case, Windows uses the 32-bit addresses.

Ignored bits must be preserved according to the ACPI spec.
Usually this means a read/modify/write when writing to the

clear the event. Writing a zero means preserve the event (do not
clear.) This behavior is clarified in the ACPI 4.0 spec, and the
ACPICA code now simply always writes a zero to the ignored bit.

acpi: fix of pmtimer overflow that make Cx states time incorrect
We found Cx states time abnormal in our some of machines which have 16
LCPUs, the C0 take too many time while system is really idle when kernel
enabled tickless and highres. powertop output is below:
PowerTOP version 1.9 (C) 2007 Intel Corporation
Cn Avg residency P-states (frequencies)
C0 (cpu running) (40.5%) 2.53 Ghz 0.0%
C1 0.0ms ( 0.0%) 2.53 Ghz 0.0%
C2 128.8ms (59.5%) 2.40 Ghz 0.0%
1.60 Ghz 100.0%
Wakeups-from-idle per second : 4.7 interval: 20.0s
no ACPI power usage estimate available
Top causes for wakeups:
41.4% ( 24.9) <interrupt> : extra timer interrupt
20.2% ( 12.2) <kernel core> : usb_hcd_poll_rh_status
(rh_timer_func)
After tacking detailed for this issue, Yakui and I find it is due to 24
bit PM timer overflows when some of cpu sleep more than 4 seconds. With
tickless kernel, the CPU want to sleep as much as possible when system
idle. But the Cx sleep time are recorded by pmtimer which length is
determined by BIOS. The current Cx time was gotten in the following
function from driver/acpi/processor_idle.c:
static inline u32 ticks_elapsed(u32 t1, u32 t2)
{
if (t2 >= t1)
return (t2 - t1);
else if (!(acpi_gbl_FADT.flags & ACPI_FADT_32BIT_TIMER))
return (((0x00FFFFFF - t1) + t2) & 0x00FFFFFF);
else
return ((0xFFFFFFFF - t1) + t2);
}
If pmtimer is 24 bits and it take 5 seconds from t1 to t2, in above
function, just about 1 seconds ticks was recorded. So the Cx time will be
reduced about 4 seconds. and this is why we see above powertop output.
To resolve this problem, Yakui and I use ktime_get() to record the Cx
states time instead of PM timer as the following patch. the patch was
tested with i386/x86_64 modes on several platforms.

The ACPI code currently carries its own thermal trip handling, meaning that
any other thermal implementation will need to reimplement it. Move the code
to the generic thermal layer.

makes it difficult to use from within the kernel. Change the interface
to use integers and fix up the consumers.
