There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.Fix these broken references, sometimes by dropping the irrelevant text
they were part of.Signed-off-by: Paul Bolle

Handle events 0x4010 and 0x4011 so that we do not pester users about them.
These events report when the thinkpad is docked/undocked to a native
hotplug dock (i.e. one that does not need ACPI handling, nor is represented
in the ACPI device tree). Such docks are based on USB 2.0/3.0, and also
work as port replicators.We really want a proper dock class to report these, or at least new input
EV_SW events. Since it is not clear which one to use yet, keep reporting
them as vendor-specific ThinkPad events.WARNING: As defined by the thinkpad-acpi sysfs ABI rules of engagement, the
vendor-specific events will be REMOVED as soon as generic events are made
available (duplicate events are a big problem), with an appropriate update
to the thinkpad-acpi sysfs/event ABI versioning. Userspace is already
prepared to provide easy backwards compatibility for such changes when
convenient to the distro (see acpi-fakekey).* Event 0x4010: docking to hotplug dock/port replicator
* Event 0x4011: undocking from hotplug dock/port replicatorTypical usecase would be to trigger display reconfiguration.
Reports mention T410, T510, and series 3 docks/port replicators. Special
thanks to Robert de Rooy for his extensive report and analysis of the
situation.http://www.thinkwiki.org/wiki/ThinkPad_Port_Replicator_Series_3

Handle some user interface events from the newer Lenovo models. We are likely
to do something smart with these events in the future, for now, hide the ones
we are already certain about from the user and userspace both.* Events 0x6000 and 0x6005 are key-related. 0x6005 is not properly identified
yet. Ignore these events, and do not report them.* Event 0x6040 has not been properly identified yet, and we don't know if it
is important (looks like it isn't, but still...). Keep reporting it.* Change the message the driver outputs on unknown 0x6xxx events, as all
recent events are not related to thermal alarms. Degrade log level from
ALERT to WARNING.Thanks to all users who reported these events or asked about them in a number
of mailing lists. Your help is highly appreciated, even if I did took a lot of
time to act on them. For that I apologise.I will list those that identified the reasons for the events as "reported-by",
and I apologise in advance if I leave anyone out: it was not done on purpose, I
made the mistake of not properly tagging all event report emails separately,
and might have missed some.Signed-off-by: Henrique de Moraes Holschuh

Below you will find an updated version from the original series bunching all patches into one big patch
updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.Signed-off-by: Justin P. Mattock

Given the right combination of ThinkPad and X.org, just reading the
video output control state is enough to hard-crash X.org.Until the day I somehow find out a model or BIOS cut date to not
provide this feature to ThinkPads that can do video switching through
X RandR, change permissions so that only processes with CAP_SYS_ADMIN
can access any sort of video output control state.This bug could be considered a local DoS I suppose, as it allows any
non-privledged local user to cause some versions of X.org to
hard-crash some ThinkPads.Reported-by: Jidanni

Add the basic ALSA mixer functionality. The mixer is event-driven,

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.Signed-off-by: Henrique de Moraes Holschuh

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.Signed-off-by: Henrique de Moraes Holschuh

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.Signed-off-by: Henrique de Moraes Holschuh

Update the HKEY event driver to:
1. Handle better the second-gen firmware, which has no HKEY mask
support but does report FN+F3, FN+F4 and FN+F12 without the need
for NVRAM polling.a) always make the mask-related attributes available in sysfs;
b) use DMI quirks to detect the second-gen firmware;
c) properly report that FN+F3, FN+F4 and FN+F12 are enabled,
and available even on mask-less second-gen firmware;2. Decouple the issuing of hotkey events towards userspace from
their reception from the firmware. ALSA mixer and brightness
event reporting support will need this feature.3. Clean up the mess in the hotkey driver a great deal. It is
still very convoluted, and wants a full refactoring into a
proper event API interface, but that is not going to happen
today.4. Fully reset firmware interface on resume (restore hotkey
mask and status).5. Stop losing polled events for no good reason when changing the
mask and poll frequencies. We will still lose them when the
hotkey_source_mask is changed, as well as any that happened
between driver suspend and driver resume.The hotkey subdriver now has the notion of user-space-visible hotkey
event mask, as well as of the set of "hotkey" events the driver needs
(because brightness/volume change reports are not just keypress
reports in most ThinkPad models).With this rewrite, the ABI level is bumped to 0x020500 should
userspace need to know it is dealing with the updated hotkey
subdriver.Signed-off-by: Henrique de Moraes Holschuh

Some analysis of the ACPI DSDTs shows that the HKEY pre-enabled mask
is always 0x80c (FN+F3,FN+F4 and FN+F12), which are the hotkeys that
the second gen of HKEY firmware supported (the first gen didn't report
any hotkeys, the second reported these tree hotkeys but had no mask
support, and the third added mask support).So, this is probably some sort of backwards compatibility with older
versions of the IBM ThinkVantage suite. We have no use for that, and
I know of exactly ZERO users of that attribute, anyway. Start the
process of getting rid of it.Signed-off-by: Henrique de Moraes Holschuh

The standard ACPI dock driver can handle the hotplug bays and docks of
the ThinkPads just fine (including batteries) as of 2.6.27, and the
code in thinkpad-acpi for the dock and bay subdrivers is currently
broken anyway...Userspace needs some love to support the two-stage ejection nicely,
but it is simple enough to do through udev rules (you don't even need
HAL) so this wouldn't justify fixing the dock and bay subdrivers,
either.That leaves warm-swap bays (_EJ3) support for thinkpad-acpi, as well
as support for the weird dock of the model 570, but since such support
has never left the "experimental" stage, it is also not a strong
enough reason to find a way to fix this code.Users of ThinkPads with warm-swap bays are urged to request that _EJ3
support be added to the regular ACPI dock driver, if such feature is
indeed useful for them.Signed-off-by: Henrique de Moraes Holschuh

Support reading the tachometer of the auxiliary fan of a X60/X61.
It was found out by sheer luck, that bit 0 of EC register 0x31
(formely HBRV) selects which fan is active for tachometer readings
through EC 0x84/0x085: 0 for fan1, 1 for fan2.Many thanks to Christoph Kl??nter, to Whoopie, and to weasel, who
helped confirm that behaviour.Fan control through EC HFSP applies to both fans equally, regardless
of the state of bit 0 of EC 0x31. That matches the way the DSDT uses
HFSP.In order to better support the secondary fan, export a second
tachometer over hwmon, and add defensive measures to make sure we are
reading the correct tachometer.Support for the second fan is whitelist-based, as I have not found
anything obvious to look for in the DSDT to detect the presence of
the second fan.Signed-off-by: Henrique de Moraes Holschuh

Forcing thinkpad-acpi to do EC-based brightness control (HBRV) on a
X61 has very... interesting effects, instead of doing nothing (since
it doesn't have EC-based backlight control), it causes "weirdness" in
the fan tachometer readings, for example.This means the EC register that used to be HBRV has been reused by
Lenovo for something else, but they didn't remove it from the DSDT.Make sure the documentation reflects this data, and forbid the user
from forcing the driver to access HBRV on Lenovo ThinkPads.Signed-off-by: Henrique de Moraes Holschuh
