Subject: [git pull request] ACPI and driver patches for 2.6.33.merge
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
I admit that I didn't have a bunch of this stuff up in linux-next,
for I pushed a batch quite recently and linux-next was
using last week's tree due to merge conflicts.
Anyway, this completes the ACPICA changes we
started for this release.
The bulk of the platform driver updates should be in here,
though I do expect some smaller updates still.
I also expect some ACPI bug fixes which are now percolating.
This will update the files shown below.
thanks!

ACPI processor: Fix section mismatch for processor_add()
Due to the merge of processor_start() (declared with __cpuinit) into
processor_add(), a section mismatch warning appears:
WARNING: drivers/built-in.o(.text+0x4d59d): Section mismatch in reference
from the function acpi_processor_add() to the function
.cpuinit.text:acpi_processor_power_init()
...
This patch fixes the warning by declaring processor_add() as __cpuinit
and also declares acpi_processor_add_fs() as __cpuinit as it is only
used in acpi_processor_add().

Toshiba Bluetooth Enabling driver (RFKill handler v3)
This patch adds support for the ACPI events generated by the RFKill
switch on modern Toshiba laptops, and re-enables the Bluetooth USB
device when the switch is flipped back to the 'on' position.
The RFKill switch brute force pulls out the USB device when flipped to
'off', but it doesn't automatically re-enable it. Without this driver,
the Bluetooth is gone until after a reboot on my Portege R500.

ACPI: fix for lapic_timer_propagate_broadcast()
I got following warning on ia64 box:
In function 'acpi_processor_power_verify':
642: warning: passing argument 2 of 'smp_call_function_single' from

This smp_call_function_single() was introduced by a commit

The problem is that the lapic_timer_propagate_broadcast() has 2 versions:
One is real code that modified in the above commit, and the other is NOP
code that used when !ARCH_APICTIMER_STOPS_ON_C3:
static void lapic_timer_propagate_broadcast(struct acpi_processor *pr) { }
So I got warning because of !ARCH_APICTIMER_STOPS_ON_C3.
We really want to do nothing here on !ARCH_APICTIMER_STOPS_ON_C3, so
modify lapic_timer_propagate_broadcast() of real version to use
smp_call_function_single() in it.

ACPI: dock: add struct dock_station * directly to platform device data
Instead of adding a (struct dock_station **) to our dock device's
platform data, we can add the (struct dock_station *) directly.
This change saves us some ugly casting and improves readability.
The cost of making this change is an extra 290 bytes of stack usage,
but this is an infrequently called code-path and unlikely to cause
the kernel to blow up.

thinkpad-acpi: disable volume control
Disable volume control by default. It can be enabled at module load
time by a module parameter (volume_control=1).
The audio control mixer that thinkpad-acpi interacts with is fully
functional without any drivers, and operated by hotkeys.
The idea behind the console audio control is that the human operator
is the only one that can interact with it. The ThinkVantage suite in
Windows does not allow any software-based overrides, and only does OSD
(on-screen-display) functions.
The Linux driver will, with the addition of the ALSA interface, try to
follow and enforce the ThinkVantage UI design:
The user is supposed to use the keyboard hotkeys to interact with the
console audio control. The kernel and the desktop environment is
supposed to cooperate to provide proper user feedback through
on-screen-display functions.
Distros are urged to not to enable volume control by default.
Enabling this must be a local admin's decision. This is the reason
why there is no Kconfig option.
Keep in mind that all ThinkPads have a normal, main mixer (AC97 or
HDA) for regular software-based audio control. We are not talking
about that mixer here.
Advanced users are, of course, free to enable volume control and do as
they please.

thinkpad-acpi: support MUTE-only ThinkPads
Lenovo removed the extra mixer since the T61 and thereabouts.
Newer Lenovo models only have the mute gate function, and leave
the volume control to the HDA mixer.
Until a way to automatically query the firmware about its audio
control capabilities is discovered (there might not be any), use a
white/black list.
We will likely need to ask T60 (old and new model) and Z60/Z61 users
whether they have volume control to populate the black/white list.
Meanwhile, provide a volume_capabilities parameter that can be used to
override the defaults.

thinkpad-acpi: volume subdriver rewrite
I don't trust the coupled EC writes and SMI calls the current volume
control code does very much, although it is exactly what the IBM DSDTs
seem to do (they never do more than a single step though).
Change the driver to stop issuing SMIs, and just drive the EC directly
to the desired level (DSDTs seem to confirm this will work even on
very old models like the 570 and 600e/x).
We checkpoint directly to NVRAM (this can be turned off) at
suspend/shutdown/driver unload, which from what I can see in tbp,
should also work on every ThinkPad.

Currently, ARB_DISABLE is a NOP on all of the recent Intel platforms.
For such platforms, reduce contention on c3_lock by skipping the fake
ARB_DISABLE.
The cpu model id on one laptop is 14. If we disable ARB_DISABLE on this box,
the box can't be booted correctly. But if we still enable ARB_DISABLE on this
box, the box can be booted correctly.
So we still use the ARB_DISABLE for the cpu which mode id is less than 0x0f.

dell-wmi: Add support for new Dell systems
Newer Dell systems support HotKey features differently from legacy
systems. A new vendor specifc HotKey SMBIOS table (Type 0xB2) is
defined. This table contains a mapping between scancode and the
corresponding predefined keyfunction ( i.e. keycode).. Also, a new
ACPI-WMI event type (called KeyIDList) with a value of 0x0010 is
defined. Any BIOS containing 0xB2 table will send hotkey notifications
using KeyIDList event.
This is Rezwanul's patch, updated to ensure that brightness events are
not sent if the backlight is controlled via ACPI and with the default
keycode for the display output switching altered to match desktop
expectations.

eeepc-laptop: callbacks should use "driver data" parameter or field
Callback methods should not refer to a variable like "eeepc" (formally
"ehotk"). Instead, they should extract the data they need either from
a "driver data" parameter, or the "driver data" field of the object
which they operate on. The "eeepc" variable can then be removed.
In practice, drivers under "drivers/platform" can get away without using
driver data, because it doesn't make sense to have more than one
instance of them. However this makes it harder to review them for
correctness. This is especially true for core ACPI developers who have
not previously been exposed to this anti-pattern :-).
This will serve as an example of best practice for new driver writers
(whether they find it themselves, or have it pointed out during review
:-).
The hwmon sub-device is a special case. It uses ec_{read,write} which
are defined to communicate with the (first) EC, so it does not require
any driver data. It should still only be instantiated in the context of
an ASUS010 device because we don't have a safe way to probe for it.

eeepc-laptop: revise names
eeepc-laptop now does a lot more than just hotkeys. Replace the "hotk"
names used throughout the driver with some slightly more appropriate
names. The actual strings used in kernel messages and sysfs are left
unchanged.
e.g.
EEEPC_HOTK_FILE -> EEEPC_LAPTOP_FILE
EEEPC_HOTK_HID -> EEEPC_ACPI_HID
eeepc_hotk_notify -> eeepc_acpi_notify
struct eeepc_hotk -> struct eeepc_laptop
ehotk -> eeepc
I'm about to refactor the entire driver to remove the global "ehotk"
variable, and I don't wish to add "struct eeepc_hotk *ehotk" to
functions which have nothing to do with hotkeys.
Also
- fix the name of "eepc_get_entry_by_keycode()"
- remove the unused definition of NOTIFY_WLAN_ON.

The eeepc-laptop driver implements a number of interfaces like the

up/down key events even if the brightness is already at the
maximum/minimum value. This is consistent with the new uevent
interface.

eeepc-laptop: simplify how the hwmon device reads values from the EC
The hwmon device uses ec_write() to write values to the EC. So for
consistency it should use ec_read() to read values. The extra layers
of indirection used did not add any value.
This may mean we no longer take the ACPI global lock for such reads
(if the EC operation region requires the lock and the EC does not).
But there is no point locking each one-byte read individually, when
write operations do not use the lock at all.

eeepc-laptop: fix value of pwm1_enable to match documentation
Documentation/hwmon/sysfs-interface tells us that automatic fan speed
control should be represented by a value of 2 or above for pwm1_enable.
Fix eeepc_get_fan_ctrl() to return 2 for automatic fan control.
Setting "1" for manual control is already consistent with the
documentation, so this remains unchanged.
Let's preserve the ABI for this specific driver, so that writing "0"
will still invoke automatic control.
(The documentation says setting "0" should leave the fan at full speed
all the time. This mode is not directly supported by our hardware. Full
speed is rather noisy on my 701 and the automatic control has never used
it. If you really want this e.g. to prolong the life of an EeePC used
as a server, you can always use manual mode. hwmon has always been
fairly machine-specific, and you're in a tiny minority (or elite :-).
I'm sure you're smart enough to notice that the fan doesn't turn on to
full speed when you try this mode, either by ear or checking
fan_input1.
We could even claim to be honouring the spirit of the documentation.
"0" really means "safe mode". EeePCs default to automatic mode, ie that
is what Asus will actually test. Since we do not provide any way to
tamper with the temperature threshold, automatic mode _is_ the safe
option).

eeepc-laptop: Remove redundant NULL checks
The acpi device callbacks add, start, remove, suspend and resume can
never be called with a NULL acpi_device. Each callsite in acpi/scan.c
has to dereference the device in order to get the ops structure, e.g.
struct acpi_device *acpi_dev = to_acpi_device(dev);
struct acpi_driver *acpi_drv = acpi_dev->driver;
if (acpi_drv && acpi_drv->ops.suspend)
return acpi_drv->ops.suspend(acpi_dev, state);
Remove all checks for acpi_dev == NULL within these callbacks.
Also remove the checks for acpi_driver_data(acpi_dev) == NULL. None of
these checks could fail unless the driver does something strange
(which none of them do), the acpi core did something terribly wrong,
or we have a memory corruption issue. If this does happen then it's

thinkpad-acpi: preserve rfkill state across suspend/resume
Since the rfkill rework in 2.6.31, the driver is always resuming with
the radios disabled.
Change thinkpad-acpi to ask the firmware to resume with the radios in
the last state. This fixes the Bluetooth and WWAN rfkill switches.
Note that it means we respect the firmware's oddities. Should the
user toggle the hardware rfkill switch on and off, it might cause the
radios to resume enabled.
UWB is an unknown quantity since it has nowhere the same level of
firmware support (no control over state storage in NVRAM, for
example), and might need further fixing. Testers welcome.
This change fixes a regression from 2.6.30.

thinkpad-acpi: fix default brightness_mode for R50e/R51
According to a report, the R50e wants EC-based brightness control,
even if it uses an Intel GPU. The current driver default was reported
to not work at all.
This bug can be worked around by the "brightness_mode=3" module
parameter.
Change the default of the R50e and R51 2xxx models (which use the same
EC firmware, 1V) to TPACPI_BRGHT_Q_EC, but keep TPACPI_BRGHT_Q_ASK set
for now, as I'd like to get more reports.

ACPI: Notify the _PPC evaluation status to the platform
According to the ACPI spec(section 8.4.4.3) OSPM should convey the _PPC
evaluations status to the platform if there exists the _OST object.
The _OST contains two arguments:
The first is the PERFORMANCE notificatin event.
The second is the status of _PPC object.
OSPM will convey the _PPC evaluation status to the platform.
Of course when the module parameter of "ignore_ppc" is added, OSPM won't
evaluate the _PPC object. But it will call the _OST object.
At the same time the _OST object will be evaluated only when the PERFORMANCE
notification event is received.

Setting polling_delay is useless as passive_delay has priority,
so the value shown in proc isn't the actual polling delay. It
also gives the impression to the user that he can change the

Also, unset passive_delay when the forced passive trip point is
unbound to allow polling to be disabled.

Users can force a passive trip point for a thermal zone that does not
have _PSV defined in ACPI by setting the passive attribute in sysfs.
It's useful to display such trip points in /proc/acpi/thermal_zone.

wmi: Add support for module autoloading
WMI provides interface-specific GUIDs that are exported from modules as
modalises, but the core currently generates no events to trigger module
loading. This patch adds support for registering devices for each WMI GUID
and generating the appropriate uevent.
Based heavily on a patch by Carlos Corbacho (<carlos@...angeworlds.co.uk>).

ACPI: dock: convert sysfs attributes to an attribute_group
As suggested by Dmitry Torokhov, convert the individual sysfs
attributes into an attribute group.
This change eliminates quite a bit of copy/paste code in the
error handling paths.
