Henrique de Moraes Holschuh a713b4d7bc 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.

Henrique de Moraes Holschuh 01e88f2598 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.

Henrique de Moraes Holschuh b2c985e7eb 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.

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...

Starting in 2.6.23...

Several reports from X60 users complained that the default Lenovo keymap
issuing EV_KEY KEY_BRIGHTNESS_UP/DOWN input events caused major issues when
the proper brightness support through ACPI video.c was loaded.

Therefore, remove the generation of these events by default, which is the
right thing for T60, X60, R60, T61, X61 and R61 with their latest BIOSes.

Distros that want to misuse these events into OSD reporting (which requires
an ugly hack from hell in HAL) are welcome to set up the key map they need
through HAL.  That way, we don't break everyone else's systems.

Henrique de Moraes Holschuh e11e211a0b ACPI: thinkpad-acpi: prefer standard ACPI backlight level control
Newer Lenovo BIOSes support the standard ACPI backlight brightness
interface (_BCM, _BQC, _BCL).  It should be used instead of the native
thinkpad backlight brightness control interface when possible.

This patch disables the native brightness support in the driver by default
when we detect that the standard ACPI interface is available.  The local
admin can still enable it using the module parameter "brightness_enable".

Note that we need to detect the standard ACPI backlight interface only in
boxes for which we would load the native backlight interface in the first
place, and that no ThinkPad BIOS has _BCL but misses the other methods, so
the detection routines can be really simple.

Henrique de Moraes Holschuh 87cc537a54 ACPI: thinkpad-acpi: add brightness_force parameter
Add a "brightness_enable" module parameter that allows the local admin to
force the backlight support to not be enabled.

It can also be used to force the backlight support to be enabled, but that
is currently a no-op as the backlight support is enabled by default when
available.  This will be changed by a different patch.

Henrique de Moraes Holschuh a3f104c02a ACPI: thinkpad-acpi: support 16 levels of brightness (v3)
Lenovo ThinkPads often have 16 brightness levels in EC, and not just eight
levels like older ThinkPads.  They also have standard ACPI backlight
brightness control.

We detect the number of brightness levels by the presence of a BCLL package
with 16 entries.  If BCLL is not there, we assume eight levels (Z6*).  If
it is there, but it doesn't have 16 entries, we assume eight levels (T60).
Otherwise we assume sixteen levels (T61, X61, etc).

We don't use _BCL because it can have side-effects in thinkpads.  Thanks to
Thomas Renninger <trenn@suse.de> for notifying me of this potential
problem.

Using the standard ACPI backlight brightness control *instead* of the
native thinkpad backlight control is a better idea, though.  A different
patch will take care of this.

Henrique de Moraes Holschuh e927c08da5 ACPI: thinkpad-acpi: revert keymap changes
Revert commit fba956c46a, "Map volume and
brightness events on thinkpads".

That commit made some modifications to the default keymaps that cause bad
behaviour on all IBM ThinkPads if HAL doesn't know to change them into
passive (on-screen-display only) events.

The proper solution for IBM ThinkPads is to use the _NOTIFY version of the
key codes for the IBM default map (which are not available in mainline
yet), and for the Lenovo keymap, it will take some studying of the various
DSDTs and testing to know the best path (which I will do shortly).

This changes the uevent buffer functions to use a struct instead of a

Jeff Garzik 1855256c49 drivers/firmware: const-ify DMI API and internals
Three main sets of changes:

1) dmi_get_system_info() return value should have been marked const,
   since callers should not be changing that data.

2) const-ify DMI internals, since DMI firmware tables should,
   whenever possible, be marked const to ensure we never ever write to
   that data area.

3) const-ify DMI API, to enable marking tables const where possible
   in low-level drivers.

And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.

The bulk of the changes are #2 and #3, which are interrelated.  #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.

Henrique de Moraes Holschuh ff80f1370f ACPI: thinkpad-acpi: revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED option
Revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED Kconfig option because
it would create a legacy we don't want to support.

CONFIG_THINKPAD_ACPI_INPUT_ENABLED was added to try to fix an issue that is
now moot with the addition of the netlink ACPI event report interface to
the ACPI core.

Now that ACPI core can send events over netlink, we can use a different
strategy to keep backwards compatibility with older userspace, without the
need for the CONFIG_THINKPAD_ACPI_INPUT_ENABLED games.  And it arrived
before CONFIG_THINKPAD_ACPI_INPUT_ENABLED made it to a stable mainline
kernel, even, which is Good.

This patch is in sync with some changes to thinkpad-acpi backports, that
will keep things sane for userspace across different combinations of kernel
versions, thinkpad-acpi backports (or the lack thereof), and userspace
capabilities:

Unless a module parameter is used, thinkpad-acpi will now behave in such a
way that it will work well (by default) with userspace that still uses only
the old ACPI procfs event interface and doesn't care for thinkpad-acpi
input devices.

It will also always work well with userspace that has been updated to use
both the thinkpad-acpi input devices, and ACPI core netlink event
interface, regardless of any module parameter.

The module parameter was added to allow thinkpad-acpi to work with
userspace that has been partially updated to use thinkpad-acpi input
devices, but not the new ACPI core netlink event interface.  To use this
mode of hot key reporting, one has to specify the hotkey_report_mode=2
module parameter.

The thinkpad-acpi driver exports the value of hotkey_report_mode through
sysfs, as well.  thinkpad-acpi backports to older kernels, that do not
support the new ACPI core netlink interface, have code to allow userspace
to switch hotkey_report_mode at runtime through sysfs.  This capability
will not be provided in mainline thinkpad-acpi as it is not needed there.

Zhang Rui 962ce8ca06 ACPI: don't duplicate input events on netlink
The previous events patch added a netlink event for every

However, some users of /proc/acpi/event are really input events,
and they already report their events via the input layer.

Introduce a new interface, acpi_bus_generate_netlink_event(),
which is explicitly called by devices that want to repoprt
events via netlink.  This allows the input-like events
to opt-out of generating netlink events.  In summary:

events that are sent via netlink:
	ac/battery/sbs
	thermal
	processor
	thinkpad_acpi dock/bay

events that are sent via input layer:
	button
	video hotkey

Userspace is supposed to remap them if it wants to use the input device for
hot key reporting.

The change in the size of the hotkey mask, the hability to report the keys
that use the higher bits, and the addition of the hotkey_radio_sw attribute
are important enough features to warrant increasing the minor field of the

Also, document a bit better how and when the thinkpad-acpi sysfs interface
version will be updated.

Henrique de Moraes Holschuh 74941a69af ACPI: thinkpad-acpi: export to sysfs the state of the radio slider switch
Some ThinkPad models, notably the T60 and X60, have a slider switch to
enable and disable the radios.  The switch has the capability of
force-disabling the radios in hardware on most models, and it is supposed
to affect all radios (WLAN, WWAN, BlueTooth).

Export the switch state as a sysfs attribute, on ThinkPads where it is
available.

Thanks to Henning Schild for asking for this feature, and for tracking down
the EC register that holds the radio switch state.

And the driver knows which keys are always handled by the firmware in all

way, do *not* enable hotkeys that are always handled by the firmware.

Henrique de Moraes Holschuh ae92bd17ff ACPI: thinkpad-acpi: enable more hotkeys
Revise ACPI HKEY functionality to better interface with the firmware, and
enable up to 32 regular hotkeys, instead of just 16 of them.  Ouch.

This takes care of most keys one used to have to do CMOS NVRAM polling on,
and should drop the need for tpb, thinkpad-keys, and other such 5Hz NVRAM
polling power vampires on most modern ThinkPads ;-)

And, just to add insult to injury, this was sort of working since forever
through the procfs interface, but nobody noticed or tried an echo
0xffffffff > /proc/acpi/ibm/hotkey and told me it would generate weird
events. ARGH!

Thanks to Richard Hughes for kicking off the work that ended up with this
discovery, and to Matthew Garret for calling my attention to the fact that
newer ThinkPads were indeed generating ACPI GPEs when such hot keys were
pressed.

Tejun Heo 7b595756ec sysfs: kill unnecessary attribute->owner
sysfs is now completely out of driver/module lifetime game.  After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners.  Note that

accessing removed modules.

This patch kills now unnecessary attribute->owner.  Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

Lennart Poettering 4f5c791a85 DMI-based module autoloading
The patch below adds DMI/SMBIOS based module autoloading to the Linux
kernel. The idea is to load laptop drivers automatically (and other
drivers which cannot be autoloaded otherwise), based on the DMI system
identification information of the BIOS.

Right now most distros manually try to load all available laptop
drivers on bootup in the hope that at least one of them loads
successfully. This patch does away with all that, and uses udev to
automatically load matching drivers on the right machines.

Basically the patch just exports the DMI information that has been
parsed by the kernel anyway to userspace via a sysfs device
/sys/class/dmi/id and makes sure that proper modalias attributes are
available. Besides adding the "modalias" attribute it also adds
attributes for a few other DMI fields which might be useful for
writing udev rules.

This patch is not an attempt to export the entire DMI/SMBIOS data to
userspace. We already have "dmidecode" which parses the complete DMI
info from userspace. The purpose of this patch is machine model
identification and good udev integration.

To take advantage of DMI based module autoloading, a driver should
export one or more MODULE_ALIAS fields similar to these:

MODULE_ALIAS("dmi:*:svnMICRO-STARINT'LCO.,LTD:pnMS-1013:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");
MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1058:pvr0581:rvnMSI:rnMS-1058:*:ct10:*");
MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1412:*:rvnMSI:rnMS-1412:*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");
MODULE_ALIAS("dmi:*:svnNOTEBOOK:pnSAM2000:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");

These lines are specific to my msi-laptop.c driver. They are basically
just a concatenation of a few carefully selected DMI fields with all
potentially bad characters stripped.

Besides laptop drivers, modules like "hdaps", the i2c modules
and the hwmon modules are good candidates for "dmi:" MODULE_ALIAS
lines.

Besides merely exporting the DMI data via sysfs the patch adds
support for a few more DMI fields. Especially the CHASSIS fields are
very useful to identify different laptop modules. The patch also adds
working MODULE_ALIAS lines to my msi-laptop.c driver.

I'd like to thank Kay Sievers for helping me to clean up this patch
for posting it on lkml.

Patch is against Linus' current GIT HEAD. Should probably apply to
older kernels as well without modification.

Henrique de Moraes Holschuh cc4c24e115 ACPI: thinkpad-acpi: do not use named sysfs groups
The initial version of the thinkpad-acpi sysfs interface (not yet released
in any stable mainline kernel) made liberal use of named sysfs groups, in
order to get the attributes more organized.

This proved to be a really bad design decision.  Maybe if attribute groups
were as flexible as a real directory, and if binary attributes were not
second-class citizens, the idea of subdirs and named groups would not have
been so bad.

This patch makes all the thinkpad-acpi sysfs groups anonymous (thus
removing the subdirs), adds the former group names as a prefix (so that
hotkey/enable becomes hotkey_enable for example), and updates the
documentation.

These changes will make the thinkpad-acpi sysfs ABI a lot easier to
maintain.

Lennart Poettering 00eb43a189 acpi,msi-laptop: Fall back to EC polling mode for MSI laptop specific EC commands
The ACPI EC that is used in MSI laptops knows some non-standard
commands for changing the screen brighntess and a few other things,
which are used by the msi-laptop.c driver. Unfortunately for these
commands no GPE events for IBF and OBF are triggered. Since nowadays
the EC code uses the ec_intr=1 mode by default, this causes these
operations to timeout, although they don't fail. In result, all
operations that you can do with the msi-laptop.c driver take more or
less 1s to complete, which is awfully slow.

In one of the more recent kernels (2.6.20?) the EC subsystem has been
revamped. With that change the EC timeout has been increased. before
that increase the MSI EC accesses were slow -- but not *that* slow,
hence I took notice of this limitation of the MSI EC hardware only very
recently.

The standard EC operations on the MSI EC as defined in the ACPI spec
support GPE events properly.

The following patch adds a new argument "force_poll" to the
ec_transaction() function (and friends). If set to 1, the function
will poll for IBF/OBF even if ec_intr=1 is enabled. If set to 0 the
current behaviour is used. The msi-laptop driver is modified to make
use of this new flag, so that OBF/IBF is polled for the special MSI EC
transactions -- but only for them.

Jean Delvare 6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

arch/alpha/kernel/err_common.c
arch/alpha/kernel/err_ev6.c
arch/alpha/kernel/err_ev7.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Note that this patch depends on another header fixup patch I submitted

Henrique de Moraes Holschuh ecf2a80a97 ACPI: thinkpad-acpi: add a fan-control feature master toggle
Len Brown considers that an active by default fan control interface in
laptops may be too close to giving users enough rope.  There is a good
chance he is quite correct on this, especially if someone decides to use
that interface in applets and users are not aware of its risks.

This patch adds a master switch to thinkpad-acpi that enables or disables
the entire fan-control feature as a module parameter: "fan_control".  It
defaults to disabled.  Set it to non-zero to enable fan control.

Also, the patch removes the expermiental status from fan control, since it
is stable enough to not be called experimental, and the master switch makes
it safe enough to do so.

Henrique de Moraes Holschuh eaa7571b2d ACPI: thinkpad-acpi: add a safety net for TPEC fan control mode
The Linux ThinkPad community is not positive that all ThinkPads that do
HFSP EC fan control do implement full-speed and auto modes, some of the
earlier ones supporting HFSP might not.

If the EC ignores the AUTO or FULL-SPEED bits, it will pay attention to the
lower three bits that set the fan level.  And as thinkpad-acpi was leaving
these set to zero, it would stop(!) the fan, which is Not A Good Thing.

So, as a safety net, we now make sure to also set the fan level part of the
HFSP register to speed 7 for full-speed, and a minimum of speed 4 for auto
mode.

Also, fix some stray "thermal" files in the fan procfs description that
have been there forever, and officially support "full-speed" as the name
for the PWM-disabled state of the fan controller to keep it in line with
the hwmon interface.  It is much better a name for that mode than the
unobvious "disengaged" anyway.  Change the procfs interface to also accept
full-speed as a fan level, but still report it as disengaged for backwards
compatibility.

Export thinkpad thermal sensors to sysfs, following the hwmon

ThinkPad thermal monitoring is done by the EC.  Sensors can show up or
disappear at runtime when they are inside hotswappable hardware, such as
batteries.  Sensors that are not available return -ENXIO when accessed.

Up to 16 thermal sensors are supported on new firmware (but nobody has
reported a ThinkPad with more than 12 sensors so far), and 8 sensors are
supported on older firmware.  Thermal sensor mapping is model-specific.
Precision varies, it is 1 degree Celcius on new ThinkPads, but higher on
some older models.

Henrique de Moraes Holschuh a5763f2223 ACPI: thinkpad-acpi: uncouple subdriver init from ibms struct
Move the .init method from ibms struct to another struct, and use a list
head to control which subdrivers have been activated.

This allows us to have the subdriver init methods marked __init, saving
quite a lot of .text size, and even a bit of .data size as some data can
now be made __initdata.

Henrique de Moraes Holschuh 5fba344cfd ACPI: thinkpad-acpi: clean up probing and move init to subdrivers
Move most of the probing code to its own function, and most of the
subdriver-specific init code into subdriver init functions.

This allows us to not define pci_handle unless the dock subdriver is
enabled, as well.

This patch causes a minor userland interface change: if a subdriver doesn't
detect a capability, /proc entries for it are not created anymore (as
opposed to a /proc entry that just returned "unsupported").

Henrique de Moraes Holschuh f21f85de4b ACPI: ibm-acpi: rename driver to thinkpad-acpi
Rename the ibm-acpi driver to thinkpad-acpi.  ThinkPads are not even made
by IBM anymore, so it is high time to rename the driver...

The name thinkpad-acpi was used sometime ago by a thinkpad-specific hotkey
driver by Erik Rigtorp, around the 2.6.8-2.6.10 time frame.  The driver
apparently never got merged into mainline (it did make some trips through
-mm).  ibm-acpi was merged soon after, making its debut in 2.6.10.

The reuse of the thinkpad-acpi name shouldn't be a problem as far as user
confusion goes, as Erik's thinkpad-acpi apparently didn't get widespread
use in the Linux ThinkPad community and most hits for thinkpad-acpi in
google point to ibm-acpi anyway.

Erik, if you read this, please consider the reuse of the thinkpad-acpi name
as a compliment to your effort to make ThinkPads more useful to all of us.
