Ooi, Joyce 4c4480aad0 HID: sensor: fix attributes in HID sensor interface
User is unable to access to input-X-yyy and feature-X-yyy where
X is a hex value and more than 9 (e.g. input-a-yyy, feature-b-yyy) in HID
sensor custom sysfs interface.
This is because when creating the attribute, the attribute index is
written to using %x (hex). However, when reading and writing values into
the attribute, the attribute index is scanned using %d (decimal). Hence,
user is unable to access to attributes with index in hex values
(e.g. 'a', 'b', 'c') but able to access to attributes with index in
decimal values (e.g. 1, 2, 3,..).
This fix will change input-%d-%x-%s and feature-%d-%x-%s to input-%x-%x-%s
and feature-%x-%x-%s in show_values() and store_values() accordingly.

Srinivas Pandruvada 021afd55e2 HID: intel-ish-hid: request_irq failure
On some platforms ISH interrupt is shared, which causes request_irq to
fail. This requires IRQF_SHARED irq flag.

But IRQF_NO_SUSPEND and IRQF_SHARED should not be used together, so
removed IRQF_NO_SUSPEND flag. Anyway this driver doesn't require
IRQF_NO_SUSPEND, as this interrupt is not required during "noirq" phases
of suspending and resuming devices as well as during the time when
nonboot CPUs are taken offline and brought back online.

Srinivas Pandruvada 5459ada2b3 HID: sensor-hub: Fix packing of result buffer for feature report
When report count is more than one and report size is not 4 bytes, then we
need some packing into result buffer from the caller of function
sensor_hub_get_feature.
By default the value extracted from a field is 4 bytes from hid core
(using hid_hw_request(hsdev->hdev, report, HID_REQ_GET_REPORT)), even
if report size if less than 4 byte. So when we copy data to user buffer in
sensor_hub_get_feature, we need to only copy report size bytes even
when report count is more than 1. This is
not an issue for most of the sensor hub fields as report count will be 1
where we already copy only report size bytes, but some string fields
like description, it is a problem as the report count will be more than 1.
For example:
    Field(6)
      Physical(Sensor.OtherCustom)
      Application(Sensor.Sensor)
      Usage(11)
        Sensor.0306
        Sensor.0306
        Sensor.0306
        Sensor.0306
        Sensor.0306
        Sensor.0306
        Sensor.0306
        Sensor.0306
        Sensor.0306
        Sensor.0306
        Sensor.0306
      Report Size(16)
      Report Count(11)

Here since the report size is 2 bytes, we will have 2 additional bytes of
0s copied into user buffer, if we directly copy to user buffer from
report->field[]->value

This change will copy report size bytes into the buffer of caller for each
usage report->field[]->value. So for example without this change, the
data displayed for a custom sensor field "sensor-model":

76 00 101 00 110 00 111 00 118 00 111
(truncated to report count of 11)

With change

76 101 110 111 118 111 32 89 111 103 97

Jason Gerecke c0bf57411b HID: input: Recognize ABS_WHEEL in hidinput_calc_abs_res
The "Steering" usage (HID_UP_SIMULATION | 0xc8) is defined in HUT 1.12 as
follows:

"A steering wheel is a single degree-of-freedom device that rotates about
an axis. The zero position is always the neutral or 'straight ahead'
position, with positive values turning clockwise and negative values
turning counterclockwise. If the Coordinate Values Wrap attribute is
set, the steering wheel can be turned past 360 degrees."

The hidinput_configure_usage function canonically maps this usage to the
ABS_WHEEL axis, but hidinput_calc_abs_res does not recognize this axis
as one for which it can calculate a resolution. This effectively prevents
wheels from being assigned a proper resolution that userspace can use
to determine the precise angle of input.

This commit adds ABS_WHEEL as a rotational axis to hidinput_calc_abs_res.

Jason Gerecke e779ef2310 HID: wacom: Fix sensor outbounds and redefine as offsets from each edge
Many of Wacom's display tablets include an "outbound" area where pen
digitizing is possible but outside of the display area. To ensure that
pen coordinates are mapped to the correct on-screen location, the driver
sets the minimum and maximum axis values of X and Y to those coordinates
which coincide with the screen edge. These values are simply the
hardware minimum/maximum plus/minus the outbound size for a particular
edge.

When outbound support was added/updated in ac414da, fa77034, and
ecd618d, we decided to have the wacom_features structs store the desired
minimum and maximum values directly. In hindsight, this was perhaps not
the best choice since it has allowed minor errors to crop up unnoticed.
Some tablets have had their coordinates over-corrected (e.g. most of the
devices "fixed" in ecd618d were already adjusted in ac414da), while
others never had a correction applied (e.g. the ISDv5 325, whose
declared maximum the hardware maximum instead of the outbound maximum).

A less error-prone method of handling the outbound is to let the driver
calculate the correct minimum/maximum values by providing it with both
the actual hardware maximums and the size of the outbound on each edge.
These values are more easy to verify as correct since the values can be
trivially compared against specifications.

This patch reverts the declared maximum values to the actual hardware
maximums, e.g. as declared prior to ac414da (values for these and other
display tablets that were subsuquently introduced have been verified
against specs). Per-edge outbound sizes are stored in the wacom_features
struct as offset_{left,right,top,bottom} and used in combination with
the hardware ranges to calculate effective axis ranges for ABS_X and
ABS_Y.

Jason Gerecke 82527da319 HID: wacom: Read and internally use corrected Intuos tool IDs
The 'wacom_intuos_inout' function incorrectly assmebles tool IDs from the
proximity report, shifting the higher values of the ID four bits farther
than intended. This problem was not detected until too late, but has not
caused any issues since the incorrect IDs still fit in a 32-bit integer
and userspace programs have not required the value to match the hardware
(just that the values are unique and constant).

The tool IDs reported by the new MobileStudio Pro (or any future
HID_GENERIC device that supports them) do not suffer from the same
assembly issue, however. In order for 'wacom_intuos_get_tool_type' to
work for with both codepaths, we correct this issue internally and
have 'wacom_intuos_general' only mangle the ID when it is posted to
userspace.

Jason Gerecke 61ce346a21 HID: wacom: generic: Add support for vendor-defined "Sense" usage
Wacom's professional tablets beginning with the Intuos4 are capable of
reporting an intermediate degree of proximity where the pen is no longer
close enough to communicate with ("in prox"), but still close enough to
be sensed ("in range"). This additional state is particularly useful for
performing palm rejection as it allows the driver to disable the touch
sensor while the pen is a greater distance from the tablet.

Like other professional tablets, the new MobileStudio Pro also reports
this intermeidate "in range" proximity state. Its descriptor assigns
usage 0xff0d0036 to this bit. Normally 'wacom_equivalent_usage' would
translate this to the standard HID "Quality" usage, but since this has
a different meaning we have it explicitly ignore the usage and define
it ourselves as "Sense" (since "In Range" is already defined by the
HID standard and interpreted by our driver as meaning "in prox").

Jason Gerecke c9c095874a HID: wacom: generic: Support and use 'Custom HID' mode and usages
Wacom's new "MobileStudio Pro" tablets are the first devices in their
branded product line-up to include a usable HID descriptor for the pen
interface. Like prior branded products, the device can operate in one
of two modes: 'Standard HID', and 'Wacom Custom HID'. Although the
first mode is usable by the HID_GENERIC codepath as-is (huzzah!), it is
subject to some restrictions -- most notably pressure being limited
to 2048 levels instead of 8192. To ensure tablets that include support
for Custom HID mode work optimally, we add support for its usages and
switch the device to Custom HID mode if possible.

The usages defined for Custom HID mode are often numerically similar to
their standard HID equivalents, allowing us to write a simple translation
function that takes arbitrary HID usages as input and which returns
the corresponding standard HID usage as output (if one exists). Switching
on this translated usage instead of the actual usage allows the existing
cases to apply to both modes of operation without having to explicitly
define every Custom HID usage.

GPIO interrupts") and commit a7d2bf25a4 ("HID: i2c-hid: Do not fail
probing if gpiolib is not enabled") at the same time.

Since commit c884fbd452 ("gpio / ACPI: Add support for retrieving
GpioInt resources from a device") i2c_core already set the IRQ by
looking into the ACPI tree and retrieving the gpioInt. So we just
have some boiler-plate here that is not needed anymore.

The only downside effect here is that now we are not exiting early
enough if the irq is set to -EPROBE_DEFER or any other error, but
this is going to be fixed in the following patch.

Steinar H. Gunderson 4973ca9a01 HID: add quirk for Akai MIDImix.
The Akai MIDImix (09e8:0031) is a MIDI fader controller that speaks
regular MIDI and works well with Linux. However, initialization gets
delayed due to reports timeout:

  [3643645.631124] hid-generic 0003:09E8:0031.0020: timeout initializing reports
  [3643645.632416] hid-generic 0003:09E8:0031.0020: hiddev0: USB HID v1.11 Device [AKAI MIDI Mix] on usb-0000:00:14.0-2/input0

Adding "usbhid.quirks=0x09e8:0x0031:0x20000000" on the kernel
command line makes the issues go away.

Ioan-Adrian Ratiu 1bcaa05ebe Revert "HID: dragonrise: fix HID Descriptor for 0x0006 PID"
This reverts commit 18339f59c3 ("HID: dragonrise: fix HID...") because it
breaks certain dragonrise 0079:0006 gamepads. While it may fix a breakage
caused by commit 79346d620e ("HID: input: force generic axis to be mapped
to their user space axis"), it is probable that the manufacturer released
different hardware with the same PID so this fix works for only a subset
and breaks the other gamepads sharing the PID.

What is needed is another more generic solution which fixes 79346d620e
("HID: input: force generic axis ...") breakage for this controller: we
need to add an exception for this driver to make it keep the old behaviour
previous to the initial breakage (this is done in patch 2 of this series).

Ioan-Adrian Ratiu e159440998 HID: hid-dr: add input mapping for axis selection
Commit 79346d620e ("HID: input: force generic axis to be mapped to their
user space axis") made mapping generic axes to their userspace equivalents
mandatory and some lower end gamepads which were depending on the previous
behaviour suffered severe regressions because they were reusing axes and
expecting hid-input to multiplex their map to the respective userspace axis
by always searching for and using the next available axis.

One solution is to add a hid quirk for this type of "previous" behaviour in
hid-input to bypass the new axes policy in favour of the old one, but since
only one hardware vendor seems to be affected negatively we're better off
making and exception and mapping in the driver for now; if more vendors or
drivers turn out to experience the problem we should reconsider the quirk
solution.

Roderick Colenbrander e1bc84d007 HID: sony: Fix race condition in sony_probe
Early on the sony_probe function calls hid_hw_start to start the hardware.
Afterwards it issues some hardware requests, initializes other functionality
like Force Feedback, power classes and others. However by the time
hid_hw_start returns, the device nodes have already been created, which leads
to a race condition by user space applications which may detect the device
prior to completion of initialization. We have observed this problem many
times, this patch fixes the problem.

This patch moves most of sony_probe to sony_input_configured, which is called
prior to device registration. This fixes the race condition and the same
approach is used in other HID drivers.

Masaki Ota 9a54cf462d HID: alps: fix multitouch cursor issue
Issue reproduction procedure:

1. three or more fingers put on Touchpad.
2. release fingers from Touchpad.
3. move the cursor by one finger.
4. the cursor does not move.

Cause:

We do not notify multi fingers state correctly to input subsystem.  For
example, when three fingers release from Touchpad, fingers state is 3 -> 0. It
needs to notify first, second and third finger's releasing state.

Fix this by not breaking out on z axis and move x,y,z input handling
code to the correct place so that it's in fact per-finger.

Frank Praznik 2a24293277 HID: sony: Defer the initial USB Sixaxis output report
When initially connected via USB the Sixaxis isn't fully initialized
until the PS logo button is pressed and won't send any input reports
nor will any state set by output reports be retained.

This adds a 'defer_initialization' flag to the sony_sc struct which,
when set, will delay sending any output reports until the first input
report has arrived. This flag is used with the USB Sixaxis to ensure
that any state sent will persist since, until the PS button is pushed,
any changes sent to the controller via an output report will be lost
after a couple of seconds.

The initial state of the controller is still configured at the time
of the initial connection and won't be internally modified after that,
so any state set by the user between that time and the recepit of the
first input report won't be lost.

Frank Praznik 0f3982308b HID: sony: Relax duplicate checking for USB-only devices
Some USB-only devices which masquerade as Sixaxis controllers report the
same generic Bluetooth address for all hardware when queried via the HID
report. This causes these devices to be wrongly rejected as duplicates
when more than one is connected at once.

This introduces a connection type comparison when checking for duplicates
and only rejects the newly connected device if the existing matching
device is connected using a different connection protocol.

The results of the connection type comparison are also used when
registering power supply info as the device Bluetooth address is used
as the unique identifier string.  In cases where more than one valid
device has the same Bluetooth address the device ID is now appended
to the power supply name string to avoid name collisions when
registering the power supply information.

Since 1989dad "HID: input: ignore System Control application usages if not

descriptor. As such the MS_RDESC_3K reportdescriptor fixup can be removed.

Benjamin Tissoires 1989dada7c HID: input: ignore System Control application usages if not System Controls
Microsoft is reusing its report descriptor again and again, and part of it
looks like this:

0x05, 0x01,                    // Usage Page (Generic Desktop)        299
0x09, 0x80,                    // Usage (System Control)              301
0xa1, 0x01,                    // Collection (Application)            303
0x85, 0x03,                    //  Report ID (3)                      305
0x19, 0x00,                    //  Usage Minimum (0)                  307
0x29, 0xff,                    //  Usage Maximum (255)                309
0x15, 0x00,                    //  Logical Minimum (0)                311
0x26, 0xff, 0x00,              //  Logical Maximum (255)              313
0x81, 0x00,                    //  Input (Data,Arr,Abs)               316
0xc0,                          // End Collection                      318

While there is nothing wrong in term of processing, we do however blindly
map the full usage range (it's an array) from 0x00 to 0xff, which creates
some interesting axis, like ABS_X|Y, and a bunch of ABS_MISC + n.

While libinput and other stacks don't care that much (we can detect them),
joydev is very happy and attaches itself to the mouse or keyboard.

The problem is that joydev now handles the device as a joystick, but given
that we have a HID array, it sets all the ABS_* values to 0. And in its
world, 0 means -32767 (minimum value), which sends spurious events to games
(think Steam).

It looks like hid-microsoft tries to tackle the very same problem with its
.report_fixup callback. But fixing the report descriptor is an endless task
and is quite obfuscated.

So take the hammer, and decide that if the application is meant to be
System Control, any other usage not in the System Control range should
be ignored.

Jason Gerecke 003f50ab67 HID: wacom: Update last_slot_field during pre_report phase
If a touchscreen contains both multitouch and single-touch reports in its
descriptor in that order, the driver may overwrite information it saved
about the format of the multitouch report. This can cause the report
processing code to get tripped up and send an incorrect event stream to
userspace.

In particular, this can cause last_slot_field to be overwritten with the
result that the driver prematurely assumes it has finished processing a
slot and sending the ABS_MT_SLOT event at the wrong point in time,
associating events for the current contact with the following contact
instead.

To prevent this from occurring, we update the value of last_slot_field
durring the pre_report phase to ensure that it is correct for the report
that is to be processed.

When upowerd detects a new device, it tries to map this new device to
an input to guess its kind. It works OK for wired tablets when the
wireless module and its battery are attached, but not so well when

In that case, the battery is attached to the wireless HID node, not
the Pen or Pad HID node. So there is no input node as a parent of the
reported battery, which means it will be showed as a computer battery
in gnome-control-center.

If we set the power supply type to USB, upowerd has a heuristic that
detects "wacom_" in the name of the power_supply, and set the type to
tablet. So it's now clear that the reported battery of from a tablet.

Add i2c_hid_shutdown for i2c-hid driver to send suspend cmd & free
irq before device shutdown.

Some HW design (i.e. Umaro, a chromebook model) is that the power to
i2c hid device won't down after device shutdown. Also the i2c-hid driver
do not send suspend cmd to the hid i2c device and free its irq before
shutdown.So if We touch the touchscreen or some other i2c hid device,
the power consumtion will be go up even when the device is in shutdown
state.

this results in a deadlock situation. The deadlock results in a 5 second timeout
for I/O operations in HID drivers, so isn't fatal, but none of the I/O operations
have a chance of succeeding.

The root cause for the problem is that uhid only allows for one request to be
processed at a time per uhid instance and locks out other operations. This means
that if a user space is creating a new HID device through 'UHID_CREATE', which
ultimately triggers '.probe' through the HID layer. Then any HID request e.g. a
read for calibration data would trigger a HID operation on uhid again, but it
won't go out to userspace, because it is still stuck in UHID_CREATE.
In addition bluetooth stacks are typically single threaded, so they wouldn't be
able to handle any requests while waiting on uhid.

Lucikly the UHID spec is somewhat flexible and allows for fixing the issue,
without breaking user space. The idea which the patch implements as discussed
with David Herrmann is to decouple adding of a hid device (which triggers .probe)
from UHID_CREATE. The work will kick off roughly once UHID_CREATE completed (or
else will wait a tiny bit of time in .probe for a lock). A HID driver has to call
HID to call 'hid_hw_start()' as part of .probe once it is ready for I/O, which
triggers UHID_START to user space. Any HID operations should function now within
.probe and won't deadlock because userspace is stuck on UHID_CREATE.

We verified this patch on Bluedroid with Android 6.0 and on desktop Linux with
BlueZ stacks. Prior to the patch they had the deadlock issue.

Benjamin Tissoires a80e803a2a HID: multitouch: Add MT_QUIRK_NOT_SEEN_MEANS_UP to Surface Pro 3
The firmware found in the touch screen of an SP3 is buggy and may miss
to send lift off reports for contacts. Try to work around that issue by
using MT_QUIRK_NOT_SEEN_MEANS_UP.

Oliver Neukum ed596a4a88 HID: elo: kill not flush the work
Flushing a work that reschedules itself is not a sensible operation. It needs
to be killed. Failure to do so leads to a kernel panic in the timer code.
