e3612e8669 HID: magicmouse: report last touch up
The evdev multitouch protocol requires that a last MT sync event must be

Also, don't send events when a touch leaves.

0b778e76c1 HID: magicmouse: add param for scroll speed
The new scroll_speed param takes an integer value from 0 to 63, where 0
is slowest and 63 is fastest. The default of 32 remains the same. This
parameter also affects scroll acceleration linearly.

A second part of this change is a tightly coupled modification to the
scroll acceleration. Previously, scroll acceleration could be reset
without lifting the scroll finger. This is rather unintuitive and hard
to control in the case where a user wants faster scrolling, but wants to
hold the scroll touch for longer than a moment.

Note that scroll acceleration levels are now 1-7, where 7 is slowest. In
the previous implementation, there were 8 levels defined, but it was
impossible to start at the slowest level. In order to keep the default
scroll speed unchanged, only 7 levels are used now.

Previously, scroll events only occurred when the user moved a touch
along the middle of the touch surface. This is unintuitive for a normal

distinction is artificial. This change removes the touch area check for
a scroll event, which replicates the OS X behavior.

e5a2a04c26 HID: check for HID_QUIRK_IGNORE during probing
While the hardcoded ignore list is checked in hid_add_device(), the
user supplied ignore flags are not. Thus, the IGNORE quirk (0x0004)
cannot be used to stop usbhid from binding devices like iBuddy, which
has been recently removed from the ignore list due to product ID
conflict.

This patch adds the user quirk check to hid_add_device(), and makes
hid_add_device() return -ENODEV when HID_QUIRK_IGNORE bit is set.

HID_QUIRK_NO_IGNORE still takes precedence over HID_QUIRK_IGNORE.

With the patch, iBuddy works properly using libusb when the following
option is added to modprobe.d:

options usbhid quirks=0x1130:0x0002:0x0004

206f5f2fcb HID: roccat: propagate special events of roccat hardware to userspace
Module roccat is a char device used to report special events of roccat hardware
to userland. These events include requests for on-screen-display of profile or
dpi settings or requests for execution of macro sequences that are not stored
in device. The information in these events depends on hid device implementation
and contains data that is not available in a single hid event or else hidraw
could have been used.

It is inspired by hidraw, but uses only one circular buffer for all readers.
The device is as generic as possible so that the functionality is usable by all
(kone and upcomming) roccat device drivers.

73d5e8f77e HID: fix up 'EMBEDDED' mess in Kconfig
The whole point of making some of the drivers automatically selected
unless 'EMBEDDED' was to handle quirks transparently after their separation
from the generic core.

Over time, some of the later-added quirks grew into more standalone drivers,
implementing non-trivial features a being larger than a few bytes of code.

In addition to that, some of the standalone drivers don't make sense for
99.9% of the users, as they are very specific to rare devices.

Therefore build by default in only those drivers which

- we historically used to support even before quirk separation from the
  core code
- are isolated enough and likely to hit quite large portion of the
  users anyway (Microsoft, Logitech)

0ede76fcec USB: remove uses of URB_NO_SETUP_DMA_MAP
This patch (as1350) removes all usages of coherent buffers for USB
control-request setup-packet buffers.  There's no good reason to
reserve coherent memory for these things; control requests are hardly
ever used in large quantity (the major exception is firmware
transfers, and they aren't time-critical).  Furthermore, only seven
drivers used it.  We might as well always use streaming DMA mappings
for setup-packet buffers, and remove some extra complexity from
usbcore.

The DMA-mapping portion of hcd.c is currently in flux.  A separate
patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP
after everything else settles down.  The removal should go smoothly,
as by then nobody will be using it.

From the USB HID specification:

   The Interrupt Out pipe is optional. If a device declares an Interrupt Out
   endpoint then Output reports are transmitted by the host to the device
   through the Interrupt Out endpoint. If no Interrupt Out endpoint is
   declared then Output reports are transmitted to a device through the
   Control endpoint, using Set_Report(Output) requests.

23d021167e HID: magicmouse: fix input registration
When HIDRAW is not set, hid_hw_start() returns ENODEV as no subsystem has
claimed the magicmouse device, and probe routine bails out. Which is not what we want.

This happens because magicmouse driver is instantiating the connection to
Input subsystem itself, and since commit 28918c211d ("HID: magicmouse: fix
oops after device removal") the HID core is not registering input device
itself.

Fix this by letting HID core register the input device (so that hid_hw_start()
succeeds, as the device is claimed by at least one subsystem) and de-register
it again later before proceeding with proper input setup.

369db2a600 HID: ntrig: add sensitivity and responsiveness support
The old rejection size thresholds were too high for the 12" devices.
Larger surfaces like the Dell Studio17 exacerbated the problem since
contact size is reported on the same logical scale, making a contact
look smaller to the larger screen.

Since we have observed erroneous ghost events from these devices we
still need to filter the incoming stream.

The prior size threshold filter is still in place, though with
defaults set to leave it off.

This patch adds the two new classes of filters, those that reject
live frames before activation, and those that reject empty frames
until deactivation.  These filters are expressed in terms of a
simple state machine for clarity (I hope).

The activation filter has two components, slack and size, events
are discarded until either is satisfied.  Slack is defined as
the number of seemingly good contacts to read before accepting the
stream as valid (if the threshold is reached in the middle of a frame
the remainder of that frame is still discarded).

The deactivation filter discards empty frames until hitting a
deactivate slack.  This time measured in frames.  N-Trig devices
emit 5-8 (observed so far) empty frames at the end of multitouch
activity.  Ignoring the first few enables us to safely and gracefully
handle erroneous empty frames, thus preventing a change in the tool
state which would otherwise result in things like broken lines or
dragged objects being dropped in bad places.

Also, now that devices with different logical densities have
been observed, the aforementioned sizes are scaled from physical
to logical scales once those scales are identified.  Hopefully this
should mean that a given threshold value means the same thing across
differing devices.

75c28df87e HID: non-overlapping zeroing of extra bits
From my review of the way the unused bits of report are being zeroed,
it seems like there must be a bug. Currently, the zeroing is done
in hid_output_field and it covers any bits between the last used bit
and the end of the byte. But in case of, say, my keyboard, NumLock is
mask 0x01 and CapsLock is 0x02. Invoking hid_output_field for NumLock
definitely zeroes across CapsLock. The only reason this works is that
the fields are sorted by the offset.

It would be more correct and simpler to zero-fill the buffer into
which the fields are set.

The patch is tested with an IBM keyboard that is improperly sensitive
to out-of-report pad bits, the extra bits are still zeroed and the
fields continue to work as expected. It is also tested with good
keyboards.

In case, a related bug in RHEL 5 is tracked with Red Hat bug 513934.

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

14bf62cde7 HID: add driver for Roccat Kone gaming mouse
This Patch adds support for Kone gaming mouse from Roccat.
It provides access to profiles, settings, firmware, weight,
actual settings etc. through sysfs attributes.
Event handling of this mouse differs from standard hid behaviour
in that tilt button press is reported in each move event which
results in strange behaviour if not handled by the driver.

This is a heavily reworked version of the previously introduced driver.
The changes include most of the previously raised concerns,
memory leak and other fixes, code cleanups, adoption of additional
achieved knowlege about the hardware and is (IMHO) a much better version
than before even when I exchanged reduced USB-IO with a bigger memory
consumption.

I refused to implement one mentioned point:
Removing the 'just-because-we-can' attributes. Motivation:
Reading the clipped in weight: I'm no gamer and can't determine the
usefulness of this feature but if the manufacturer implements such a
feature it might make sense to someone and I would unwillingly limit the
functionality besides its such a small feature.
Reading the actual profile and dpi settings: Here I can testify that one
can get lost of the actual settings when switching back and forth.
The manufacturers windows driver has the ability for on-screen-display
of the values and there is a mouse in the market that has an lcd on the
underside of it to show these values. So I think this feature makes sense
not only for me and shouldn't be removed.

When dumping /sys/kernel/debug/hid/$device/events '\0' characters show up
(invisible if cat to console but shown by less or while looking at a dump
 file).  These are due to hid_debug_event() adding strlen()+1 bytes to the ring
buffer (e.g. including the trailing '\0').  Any roll-over causes a '\0' as well
as hid_debug_event() handles the ring buffers with HID_DEBUG_BUFSIZE-1 size
while hid_debug_events_read() handles it with full HID_DEBUG_BUFSIZE size.

This cleans up the behavior particularly for the latest firmware, which
didn't work particularly well with the older version of the driver.

In this form, when multitouch is active, both mt and st events will come out of

128537cea4 HID: add a device driver for the Apple Magic Mouse.
The Magic Mouse requires that a driver send an unlock Report(Feature) command,
similar to the Wacom wireless tablet and Sixaxis controller quirks.  This turns
on an Input Report that isn't published in the input Report descriptor that
contains touch data (and usually overrides the normal motion and click Report).

Because the mouse has only one switch and no scroll wheel, the driver
(under control of parameters) emulates a middle button and scroll wheel.
User space could also ignore and/or re-synthesize those events based on
the reported events.

associated with the host's HIDP stack) are at

2dbf209d7a HID: make full-fledged hid-bus drivers properly selectable
For historical reasons, we don't have most of the in-tree
drivers residing on hid-bus properly selectable in kernel
configuration unless CONFIG_EMBEDDED is set.

This has been introduced on Linus' request from 14 Oct

===
As to the Kconfig options - do they really add so much space that you need to
ask for the quirks? You didn't use to. Can you make the questions depend on
EMBEDDED, or at least on the HID_COMPAT thing or whatever?
===

This still makes perfect sense for small and tiny drivers, which
just fix report descriptors, fix up HID->input mappings that slightly
violates HUT standard, send one extra packet to the device that is
needed before it becomes functional, etc.

Since then, we have been gathering more and more HID-bus drivers,
which are full-fledged drivers. For these, the size argument becomes
more valid. Plus the devices are much more special than "just violates
HID specification in this one or two tiny unimportant points".

Therefore I am marking such drivers as properly selectable no matter
the setting of CONFIG_EMBEDDED, while keeping all the small and tiny
ones compiled by default.

342f31e84e HID: make Wacom modesetting failures non-fatal
With Wacom tablet mode-setting moved from userspace into kernel,
we don't have to consider failures of device queries through the
_raw callback as hard failure, as the driver can safely continue
anyway.

This is consistent with the current USB driver in wacom_sys.c

46a709b900 HID: Implement Wacom quirk in the kernel
The hid-wacom driver required user-space to poke at the tablet
to make it send data about the cursor location.

This patch makes it do the same thing but in the kernel.

d4bfa033ed HID: make raw reports possible for both feature and output reports
In commit 2da31939a4 ("Bluetooth: Implement raw output support for HIDP
layer"), support for Bluetooth hid_output_raw_report was added, but it
pushes the data to the intr socket instead of the ctrl one. This has been
fixed by 6bf8268f9a ("Bluetooth: Use the control channel for raw HID reports")

Still, it is necessary to distinguish whether the report in question should be
either FEATURE or OUTPUT. For this, we have to extend the generic HID API,
so that hid_output_raw_report() callback provides means to specify this
value so that it can be passed down to lower level hardware drivers (currently
Bluetooth and USB).

1c3a02c215 HID: add NOGET quirk for Prodige Cordless Combo
I happen to own a keyboard identified as 05af:3062 which is labeled as
"FlatX Coldless Combo" by "Prodige", which exhibits input problems without
NOGET quirk. For some reason, lsusb reports this device as "Jing-Mold
Enterprise Co., Ltd", which is not mentioned anywhere on the package.
A quick search on the intenet shows that there a other people who have
this in their lsusb output, but apparently they don't have the problem
I am seeing (or they are not such furious typists as myself).
