Dmitry Torokhov 1d64b655dc Input: serio/gameport - use 'long' system workqueue
Commit 8ee294cd9d converted serio
subsystem event handling from using a dedicated thread to using
common workqueue. Unfortunately, this regressed our boot times,
due to the fact that serio jobs take long time to execute. While
the new concurrency managed workqueue code manages long-playing
works just fine and schedules additional workers as needed, such
works wreck havoc among remaining users of flush_scheduled_work().

To solve this problem let's move serio/gameport works from system_wq
to system_long_wq which nobody tries to flush.

Instead of open-coding copying of data structures from userspace use
memdup_user() and strndup_user(). Note that this introduces change in

This reverts commit 5fdbe44d03.

Apparently there exist userspace programs that expect to be able to
"loop back" and distribute to readers events written into
/dev/input/eventX and this change made for the benefit of SysRq
handler broke them. Now that SysRq uses alternative method to suppress
filtering of the events it re-injects we can safely revert this change.

Duncan Laurie 19e9554153 Input: serio - clear pending rescans after sysfs driver rebind
When rebinding a serio driver via sysfs drvctl interface it is
possible for an interrupt to trigger after the disconnect of the
existing driver and before the binding of the new driver.  This will
cause the serio interrupt handler to queue a rescan event which will
disconnect the new driver immediately after it is attached.

This change removes pending rescans from the serio event queue after
processing the drvctl request but before releasing the serio mutex.

Reproduction involves issuing a rebind of device port from psmouse
driver to serio_raw driver while generating input to trigger
interrupts.  Then checking to see if the corresponding
i8042/serio4/driver is correctly attached to the serio_raw driver
instead of psmouse.

Ping Cheng 28a1bc1c0a Input: wacom_w8001 - report resolution to userland
Serial devices send both pen and touch data through the same logical
port. Since we scaled touch to pen maximum, we use pen resolution
for touch as well here.

This is under the assumption that pen and touch share the same physical
surface. In the case when a small physical dimensional difference occurs
between pen and touch, we assume the tolerance for touch point precision
is higher than pen and the difference is within touch point tolerance.

A per-MT tool based resolution mechanism should be introduced if the
above assumption does not hold true for the pen and touch devices any
more.

The driver does not require hardirq context and can work with threaded
interrupts as well, so let's switch to request_any_context_irq which
will select the context that is available for us.

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

Andres Salomon ef8313bb1a Input: psmouse - disable the synaptics extension on OLPC machines
OLPC has switched to a Synaptics touchpad.  It turns out that it's
pretty useless in absolute mode.  This patch looks for an OLPC
system (via DMI tables), and refuses to init Synaptics mode in
that scenario (falling back to relative mode).

Henrik Rydberg 4f56ce929c Input: synaptics - ignore bogus mt packet
In multitouch mode, at least one device (fw: 7.4 id: 0x1c0b1) sometimes
sends a final main packet with x == 1. Since the normal values are above
1472, this is clearly bogus. At the same time, a two-finger touch is
signaled, even though only one finger was on the pad to begin with. This
patch ignores the packet altogether, removing the problem.

Henrik Rydberg fec6e5252b Input: synaptics - add multi-finger and semi-mt support
The Synaptics 2.7 series of touchpads support a mode for reporting two
sets of X/Y/Pressure data (advanced gesture mode). By default, these
devices report only single finger data, depriving userspace of the
nowadays ubiquitous two-finger scroll gesture.

Enabling advanced gesture mode also enables the multi-finger report,
although the device does not claim that capability. Up to three
fingers can be reported this way.

While two or three fingers are touching, the normal packet is
prepended by a reduced finger packet of lower resolution. From the two
packets (which do not represent the actual fingers), the bounding
rectangle of the individual contacts can be extracted.  This
information is sufficient to perform scaling gestures and a limited
form of rotation gesture. The behavior has been coined semi-mt
capability, and is signaled to userspace via the INPUT_PROP_SEMI_MT
device property.

Work to decode the advanced gesture packet: Takashi Iwai.
Cleanup and testing of the original patch: Chase Douglas.
Minor cleanup and testing: Chris Bagwell.
Finalization and semi-mt support: Henrik Rydberg.

Henrik Rydberg 85b7720039 Input: introduce device properties
Today, userspace sets up an input device based on the data it emits.
This is not always enough; a tablet and a touchscreen may emit exactly
the same data, for instance, but the former should be set up with a
pointer whereas the latter does not need to. Recently, a new type of
touchpad has emerged where the buttons are under the pad, which
changes logic without changing the emitted data. This patch introduces
a new ioctl, EVIOCGPROP, which enables user access to a set of device
properties useful during setup. The properties are given as a bitmap
in the same fashion as the event types, and are also made available
via sysfs, uevent and /proc/bus/input/devices.

The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common
pointer emulation code, thereby removing the need for the tracking id
in the driver.  This patch moves all tracking event handling over to
the input core, simplifying both the existing drivers and the ones
currently in preparation.

Dmitry Torokhov ab4e019219 Input: define separate EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2
The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while
extending them to support large scancodes was a mistake. While we tried
to keep ABI intact (and we succeeded in doing that, programs compiled
on older kernels will work on newer ones) there is still a problem with
recompiling existing software with newer kernel headers.

New kernel headers will supply updated ioctl numbers and kernel will
expect that userspace will use struct input_keymap_entry to set and
retrieve keymap data. But since the names of ioctls are still the same
userspace will happily compile even if not adjusted to make use of the
new structure and will start miraculously fail in the field.

To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions
and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly
select the style of ioctls it wants to employ.

2-button ClickPad has the 8-bit set.

This patch makes the kernel only handle 1-button ClickPad specially,

This patches removes a config option that was used to select a FIQ
handler to be build for Amstrad Delta, as required by the on-board serio
interface driver. Not having any problem reports received since it was
introduced in 2.6.35, the FIQ handler can now be built and initialized by
default, thus reqiring no extra config option.

Jesper Juhl 39de52104d Input: serio HIL MLC - don't deref null, don't leak and return proper error
While reviewing various users of kernel memory allocation functions I came
across drivers/input/serio/hil_mlc.c::hil_mlc_register() and noticed that:

 - it calls kzalloc() but fails to check for a NULL return before use.
 - it makes several allocations and if one fails it doesn't free the
   previous ones.
 - It doesn't return -ENOMEM in the failed memory allocation case (it just
   crashes).

This patch corrects all of the above and also reworks the only caller of
this function that I could find
(drivers/input/serio/hp_sdc_mlc.c::hp_sdc_mlc_out()) so that it now checks
the return value of hil_mlc_register() and properly propagates it on
failure and I also restructured the code to remove some labels and goto's
to make it, IMHO nicer to read.

Daniel Drake c0dc834265 Input: hgpk - rework spew detection
The old implementation of spew detection simply tracked the overall
position delta of the cursor over every 100 packets. We found that
this causes occasional false positives in spew detection, and also
that the conditions of the spewy packets are perhaps more fixed than
we once thought.

Rework the spew detection to look for packets of specific small
delta, and only recalibrating if the overall movement delta stays
within expected bounds.

Also discard duplicate packets in the advanced mode, which appear
to be very common. If we don't, the spew detection kicks in far
too early. If we get a large spew of duplicates, request a
recalibration straight up.

Add a "hgpk_mode" sysfs attribute that allows selection between 3 options:
Mouse (the existing option), GlideSensor and PenTablet.

GlideSensor is an enhanced protocol for the regular touchpad mode that
additionally reports pressure and uses absolute coordinates. We suspect
that it may be more reliable than mouse mode in some environments.

PenTablet mode puts the touchpad into resistive mode, you must then use
a stylus as an input. We suspect this is the most reliable way to drive
the touchpad.

The GlideSensor and PenTablet devices expose themselves with the
intention of being combined with the synaptics X11 input driver.

Benjamin LaHaise 8c5188b6d3 Input: atkbd - add 'terminal' parameter for IBM Terminal keyboards
Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate
using a protocol similar, but not identical to the AT keyboard protocol.
(Models known to be like this include 6110344, 6110668, 1390876, 1386887, and
possibly others.)

When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they
can be connected to a standard PC, with three caveats:

a) They can only use scancode set 3; requests to use anything else are
quietly ignored.
b) The AT Command to request Make, Break and Repeat codes is not properly
interpreted.
c) The top function keys on a 122 key keyboard, and the arrow/edit keys in
the middle of the board send non-standard scancodes.

C) is easily taken care of in userspace, by use of setkeycodes
B) can be taken care of by a userspace hack (that makes the kernel complain
in dmesg)
A) is fixable in theory, but on the keyboard i tested on (6110668), it seems
to be detected unoverridably as Set 2, causing userspace oddities that make
it harder to fix C).

Enclosed is a small patch to the kernel that fixes A) and B) in the kernel,
making it much easier to fix C) in userspace. It adds a single kernel
command line parameter that overrides the detection that sets these boards
as set 2, and instead of sending the Make-break-repeat command to the
keyboard, it sends the make-break command, which is properly recognized by
these keyboards. Software level key repeating seems to make up for the lack
of hardware repeat codes perfectly.

Without manually setting the command line parameter (tentatively named
atkbd.terminal), this code has no effect, and the driver works exactly as
before.

Michael Hennerich b584efc9ea Input: ad7879 - prevent invalid finger data reports
Considering following scenario - the touch is present on the screen
at the beginning of the last conversion sequence, but by the time
the last sequence is finished, the finger is lift off. The AD7879 data
available interrupt signals (DAV) completion, however some X,Y values
are not valid because the screen inputs were floating during the
acquisition.

The AD7877 acts differently here, since it only asserts DAV if the
touch is still present when the conversion sequence finished.

Based on the fact that this can only happen in the last sample of the
repeated conversion sequence, we simply skip the last (short glitches
are filtered by the AD7879 internal median and average filters).
This doesn't cause noticeable side effects, since the minimum conversion
interval is 9.44ms. We receive ~100 waypoint samples per second, so we
simply delay the result by 9.44ms.

We also reject samples where pressure is greater than pressure_max.

Dmitry Torokhov 62ecae09a0 Input: wacom - properly enable runtime PM
We need to always call usb_autopm_put_interface() in wacom_open(),
