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().

Hidetoshi Seto [Mon, 14 Dec 2009 08:10:06 +0000]
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

 > @@ -162,8 +162,9 @@

 >
 >         return (working);
 >  }

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.

10 years agothinkpad-acpi: disable volume control
Henrique de Moraes Holschuh [Tue, 15 Dec 2009 23:51:10 +0000]
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.

10 years agothinkpad-acpi: volume subdriver rewrite
Henrique de Moraes Holschuh [Tue, 15 Dec 2009 23:51:08 +0000]
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.

thinkpad-acpi: sync input device EV_SW initial state

Before we register the input device, sync the input layer EV_SW state
through a call to input_report_switch(), to avoid issuing a gratuitous

asus-laptop: change light sens default values.

The light sensor disable brightness key and

from users who didn't understand why they couldn't change their

http://bugzilla.kernel.org/show_bug.cgi?id=13671
http://bugzilla.kernel.org/show_bug.cgi?id=14432

Now the light sensor is disabled, and if the user want to enable
it, the level should be ok.

The funny thing is that comments where ok, not code.

10 years agolis3: scale output values to mg
Samu Onkalo [Tue, 15 Dec 2009 02:01:46 +0000]
lis3: scale output values to mg

Report output values as 1/1000 of earth gravity.

Output values from lis3 can be read from sysfs position entry and from
input device.  Input device can be accessed as event device and as
joystick device.  Joystick device can be in two modes.  Meaning of the
output values varies from case to case depending on the chip type and
configuration (scale).  Only joystick interface in JS_CORR_BROKEN mode
returned somehow similar output values in different configurations.
Joystick device is in that state by default in case of lis3.

Position sysfs entry, input event device and raw joystick device have been
little bit broken since meaning of the output values has been varied
between 12 and 8 bit devices.  Applications which relayed on those methods
failed if the chip is different than the expected one.

This patch converts output values to mean similar thing in different
configurations.  Both 8 and 12 bit devices reports now same acceleration
values.  If somebody implements full scale support to the driver, output
values will still mean the same.  Scaling factor and input device range
must be updated in that case.

Joystick interface in JS_CORR_BROKEN mode is not touched by this patch.
All other interfaces have different scale after this change.  For 12 bit
device scaling factor is 0.977 which keeps scaled and unscaled values are
quite close to each others.  For 8 bit device, scaled values are 18 times
bigger than unscaled values.

10 years agolis3: selftest support
Samu Onkalo [Tue, 15 Dec 2009 02:01:43 +0000]
lis3: selftest support

Implement selftest feature as specified by chip manufacturer.  Control:
read selftest sysfs entry

Response: "OK x y z" or "FAIL x y z"

where x, y, and z are difference between selftest mode and normal mode.
Test is passed when values are within acceptance limit values.

Acceptance limits are provided via platform data.  See chip spesifications
for acceptance limits.  If limits are not properly set, OK / FAIL decision
is meaningless.  However, userspace application can still make decision
based on the numeric x, y, z values.

Selftest is meant for HW diagnostic purposes.  It is not meant to be
called during normal use of the chip.  It may cause false interrupt
events.  Selftest mode delays polling of the normal results but it doesn't
cause wrong values.  Chip must be in static state during selftest.  Any
acceration during the test causes most probably failure.

lis3: fix show rate for 8 bits chips

Originally the driver was only targeted to 12bits sensors.  When support
for 8bits sensors was added, some slight difference in the registers were
overlooked.  This should fix it, both for initialization, and for
displaying the rate.
