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.

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.

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.

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: 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.

ACPI video: Don't export sysfs backlight interface if query _BCL fail

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.
