ACPI: Populate /sys/firmware/acpi/tables/

The file name is the signature, such as DSDT,
and the contents are the binary table image.

Some tables, such as the SSDT, can have multiple instances.
If just one, the file is SSDT, but if 3 instances,
for example, it will be SSDT1, SSDT2, SSDT3

All static tables (besides teh RSDP and RSDT themselves
are exported. Dynamic tables, such as SSDT op-regions that
are not declared in the RSDT, will be added in a subsequent patch.

ACPI: create CONFIG_ACPI_DEBUG_FUNC_TRACE

Split ACPI_DEBUG into function trace enabled and not enabled.

Function trace is most of the ACPI_DEBUG costs, but is
not much of use for kernel ACPI debugging.

Size of kernel image increased on test compile:
+ 48k (Full ACPI_DEBUG)
+ 35k (ACPI_DEBUG with function trace compiled out)

Performance without function trace is also much better.

Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
a lot vendors let Store (value, debug) in their code and this
might confuse users when it pops up in syslog.

sony-laptop: Add support for recent Vaios Fn keys (C series for now)

Recent Vaios (C, AR, N, FE) need some special initialization
sequence to enable Fn keys interrupts through the Embedded
Controller. Moreover Fn keys have to be decoded internally
using ACPI methods to get the key code.
Thus a new DMI table to add SNC init time callbacks and new
mappings for model-specific key code to generic sony-laptop
code have been added.

ACPI: thinkpad-acpi: add locking to brightness subdriver

The backlight class does all the locking needed for sysfs access, but
offers no API to interface to that locking without an layer violation.

Since we need to mutex-lock procfs access, implement in-driver locking for
brightness. It will go away the day thinkpad-acpi procfs goes away, or the
backlight class gives us a way to use its locks without a layer violation.

ACPI: thinkpad-acpi: make sure DSDT TMPx readings don't return +128

We get +128 instead of -128 from the DSDT TMPx methods, due to errors when
converting a EC byte return that is a s8 to an ACPI handler return that is
an int.

Fix it once and for all, by clamping acceptable temperature readings from
DSDT TMPx so that anything outside the [-127,+127] range is converted to
TP_EC_THERMAL_TMP_NA (-128).

ACPI: thinkpad-acpi: react to Lenovo ThinkPad differences in hot key

Lenovo ThinkPads have a slightly different key map layout from IBM
ThinkPads (fn+f2 and fn+f3 are swapped). Knowing which one we are dealing
with, we can properly set a few more hot keys up by default.

Also, export the correct vendor in the input device, as that information
might be useful to userspace.

ACPI: thinkpad-acpi: allow use of CMOS NVRAM for brightness control

It appears that Lenovo decided to break the EC brightness control interface
in a weird way in their latest BIOSes. Fortunately, the old CMOS NVRAM
interface works just fine in such BIOSes.

Add a module parameter that allows the user to select which strategy to use
for brightness control: EC, NVRAM, or both. By default, do both (which is
the way thinkpad-acpi used to work until now) on IBM ThinkPads, and use
NVRAM only on Lenovo ThinkPads.

The expected user case for the radio slider switch on a ThinkPad includes

Export the information about the switch state, and switch change events as

ACPI: thinkpad-acpi: add input device support to hotkey subdriver

Add input device support to the hotkey subdriver.

Hot keys that have a valid keycode mapping are reported through the input
layer if the input device is open. Otherwise, they will be reported as
ACPI events, as they were before.

Scan codes are reported (using EV_MSC MSC_SCAN events) along with EV_KEY
KEY_UNKNOWN events.

For backwards compatibility purposes, hot keys that used to be reported
through ACPI events are not mapped to anything meaningful by default.
Userspace is supposed to remap them if it wants to use the input device for
hot key reporting.

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.

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.

On systems that do not have pm2_control_block, we cannot really use

To be compatible with Windows, we need to enable C3 on such systems now.
We just skip ARB_DISABLE step before entering the C3-state and assume
hardware is handling things correctly. Also, ACPI spec is not clear
about pm2_control is _needed_ for C3 or not.

We have atleast one system that need this to enable C3.

Currently the acpi video module export the backlight interface to sysfs
also if acpi_video_device_lcd_query_levels() fails to read _BLC method
(e.g. because the method is not available). In this case the userspace
don't know which brightness level are supported and can't set a brightness
level (echo return with: "write error: Invalid Argument"). This happend
e.g. on a ASUS RF1 (correct supported by the asus-laptop module).

The video module should not export the backlight interface if query _BLC fail,
because you can't set anything from userspace and this make it useless.

ACPI: disable _OSI(Linux) by default

In Linux-2.6.22 we expanded the boot parameter osi=
so that it can enable and !enable an OSI string.

_OSI(Linux) is a special case because we know that there
are both systems that require it set, and systems
require that it _not_ to be set. In the long term it can't
be set, for the same reason _OS(Linux) can't be enabled --
it tends to confuse BIOS that are not properly
validated with Linux. Further, the semantics and version
information of _OSI(Linux) were never actually defined.

The kernel prints out a message if it sees _OSI(Linux)
requested, and there is a DMI workaround to invoke
"osi=Linux" automatically for existing systems that need it.

ACPI: Remove Dell Optiplex GX240 from the ACPI blacklist

I have a Dell Optiplex GX240 and when I boot Linux, ACPI gets set up by only
acpi=ht. dmesg shows the following line:

DELL GX240 detected: force use of acpi=ht

Everything seemed to be fine. However, I discovered that everything is not
fine. The USB controller works so slowly that copying a few (uncached) 1
megabyte large photos from a USB-enabled digital camera takes many minutes
instead of a couple of seconds.

I am using Linux 2.6.21.1 on a Debian 4.0 ("Etch") system.

I thought that this might be related to ACPI. So I tried to boot with _only_
"acpi=force" appended to the kernel command line. Voila, the USB controller
started to work at full speed and copying photos from my digital camera took
only seconds.

I tested the system with "acpi=force" and could not find anything which did
not work.

I thought that this might be related to interrupts and APIC as well. (Note
that this is APIC, not ACPI.) I tried booting with _only_ "noapic" and
"nolapic" appended to the command line. Again, the USB controller started to
work at full speed.

ACPI: bay: send envp with uevent

Make the bay driver send env information on bay events.

Upon any bay event, we will send the string "BAY_EVENT=%d" along with the
KOBJ_CHANGE, and report the event number. What the event number means will
be platform specific. Event 3 is always an eject request, but an insert
may be either event 1, or it may be event 0. Event 1 may also be a
remove request. It would be best if you check the number of your event
with udevmonitor before writing any udev scripts for inserting and
removing drive bays.

ACPI: dock: add immediate_undock option

Allow the driver to be loaded with an option that will allow userspace to
control whether the laptop is ejected immediately when the user presses the
button, or only when the syfs undock file is written.

if immediate_undock == 1, then when the user presses the undock button, the
laptop will send an event to userspace to notify userspace of the undock, but
then immediately undock without waiting for userspace. This is the current
behavior, and I set this to be the default.

if immediate_undock == 0, then when the user presses the undock button, the
laptop will send an event to userspace and do nothing. User space can query
the "flags" sysfs entry to determine if an undock request has been made by
the user (if bit 1 is set). User space will then need to write the undock
sysfs entry to complete the undocking process.

ACPI: video: output switch sysfs support

Requires CONFIG_VIDEO_OUTPUT_CONTROL and CONFIG_ACPI_VIDEO.

After loading output.ko and video.ko, you would have
/sys/class/video_output and several device acpi_videoNum there.

For example, I got acpi_video0, acpi_video1,acpi_video2,and acpi_video3
under /sys/class/video_output on my T40.
I can query the status of output device0 by running " cat
/sys/class/video_output/acpi_video0
" The return value is defined in ACPI SPEC B.5.5 _DCS(Return the
Status of Output Device). Also you can turn off video1 and turn on
video0 by " echo 0 > acpi_video1; echo 0x80000000 > acpi_video0".
Please reference ACPI SPEC B.5.7 _DSS for the parameter definition.

Please note that it may or may NOT works purely depending on if
your vendor providing correct ACPI video extension support in bios.
the driver output.ko and video.ko just works like a interface to
invoke BIOS.

ACPI: Cache battery status instead of re-evaluating AML

/proc exports _BST in a single file, and _BST is re-evaulated
whenever that file is read.

Sometimes user-space reads this file frequently, and on some
systems _BST takes a long time to evaluate due to a slow EC.

Further, when we move to sysfs, the values returned from _BST
will be in multiple files, and evaluating _BST for each
file read would make matters worse.

Here code is added to support caching the results of _BST.
A new module parameter "update_time" tells how many seconds the
cached _BST should be used before it is re-evaluated.
Currently, update_time defaults to 0, and so the
existing behaviour of re-evaluating on each read retained.
