Greg Kroah-Hartman b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

Cameron Gutman f5308d1b83 Input: xpad - fix PowerA init quirk for some gamepad models
The PowerA gamepad initialization quirk worked with the PowerA
wired gamepad I had around (0x24c6:0x543a), but a user reported [0]
that it didn't work for him, even though our gamepads shared the
same vendor and product IDs.

When I initially implemented the PowerA quirk, I wanted to avoid
actually triggering the rumble action during init. My tests showed
that my gamepad would work correctly even if it received a rumble
of 0 intensity, so that's what I went with.

Unfortunately, this apparently isn't true for all models (perhaps
a firmware difference?). This non-working gamepad seems to require
the real magic rumble packet that the Microsoft driver sends, which
actually vibrates the gamepad. To counteract this effect, I still
send the old zero-rumble PowerA quirk packet which cancels the
rumble effect before the motors can spin up enough to vibrate.

Benjamin Valentin be19788c73 Input: xpad - sync supported devices with XBCD
XBCD [0][1] is an OpenSource driver for Xbox controllers on Windows.
Later it also started supporting Xbox360 controllers (presumably before
the official Windows driver was released).

It contains a couple device IDs unknown to the Linux driver, so I extracted
those from xbcd.inf and added them to our list.

It has a special type for Wheels and I have the feeling they might need
some extra handling. They all have 'Wheel' in their name, so that
information is available for future improvements.

Benjamin Valentin c225370e01 Input: xpad - sync supported devices with 360Controller
360Controller [0] is an OpenSource driver for Xbox/Xbox360/XboxOne
controllers on macOS.

It contains a couple device IDs unknown to the Linux driver, so I wrote a
small Python script [1] to extract them and feed them into my previous
script [2] to compare them with the IDs known to Linux.

For most devices, this information is not really needed as xpad is able to
automatically detect the type of an unknown Xbox Controller at run-time.
I've therefore stripped all the generic/vague entries.

I've excluded the Logitech G920, it's handled by a HID driver already.
I've also excluded the Scene It! Big Button IR, it's handled by an
out-of-tree driver. [3]

There are several quirky Xbox One pads that depend on initialization
packets that the Microsoft pads don't require. To deal with these,
I've added a mechanism for issuing device-specific initialization
packets using a VID/PID-based quirks list.

For the initial set of init quirks, I have added quirk handling from

macOS to enable some new pads to work properly.

This should enable full functionality on the following quirky pads:

The order of endpoints is well defined on official Xbox pads, but

Fortunately, we get lucky with this specific pad because it uses
endpoint addresses that differ only by direction. We know that
there are other pads out where this is not true, so let's go
ahead and fix this.

Cameron Gutman ae3b4469db Input: xpad - fix Xbox One rumble stopping after 2.5 secs
Unlike previous Xbox pads, the Xbox One pad doesn't have "sticky" rumble
packets. The duration is encoded into the command and expiration is handled
by the pad firmware.

ff-memless needs pseudo-sticky behavior for rumble effects to behave
properly for long duration effects. We already specify the maximum rumble
on duration in the command packets, but it's still only good for about 2.5
seconds of rumble. This is easily reproducible running fftest's sine
vibration test.

It turns out there's a repeat count encoded in the rumble command. We can
abuse that to get the pseudo-sticky behavior needed for rumble to behave as
expected for effects with long duration.

By my math, this change should allow a single ff_effect to rumble for 10
minutes straight, which should be more than enough for most needs.

Cameron Gutman f712a5a052 Input: xpad - power off wireless 360 controllers on suspend
When the USB wireless adapter is suspended, the controllers
lose their connection. This causes them to start flashing
their LED rings and searching for the wireless adapter
again, wasting the controller's battery power.

Instead, we will tell the controllers to power down when
we suspend. This mirrors the behavior of the controllers
when connected to the console itself and how the official
Xbox One wireless adapter behaves on Windows.

Cameron Gutman c7f1429389 Input: xpad - fix oops when attaching an unknown Xbox One gamepad
Xbox One controllers have multiple interfaces which all have the
same class, subclass, and protocol. One of the these interfaces
has only a single endpoint. When Xpad attempts to bind to this
interface, it causes an oops when trying initialize the output URB
by trying to access the second endpoint's descriptor.

This situation was avoided for known Xbox One devices by checking
the XTYPE constant associated with the VID and PID tuple. However,
this breaks when new or previously unknown Xbox One controllers
are attached to the system.

This change addresses the problem by deriving the XTYPE for Xbox
One controllers based on the interface protocol before checking
the interface number.

Cameron Gutman 1ff5fa3c67 Input: xpad - prevent spurious input from wired Xbox 360 controllers
After initially connecting a wired Xbox 360 controller or sending it
a command to change LEDs, a status/response packet is interpreted as
controller input. This causes the state of buttons represented in
byte 2 of the controller data packet to be incorrect until the next
valid input packet. Wireless Xbox 360 controllers are not affected.

Writing a new value to the LED device while holding the Start button
and running jstest is sufficient to reproduce this bug. An event will
come through with the Start button released.

Xboxdrv also won't attempt to read controller input from a packet
where byte 0 is non-zero. It also checks that byte 1 is 0x14, but
that value differs between wired and wireless controllers and this
code is shared by both. I think just checking byte 0 is enough to
eliminate unwanted packets.

The following are some examples of 3-byte status packets I saw:
01 03 02
02 03 00
03 03 03
08 03 00

This adds the VID/PID combination for the Xbox One version of the Mad

The functionality that this provides is about on par with what the

What works:
- Digital stick
- 6 main buttons
- Xbox button
- The two buttons on the back
- The locking buttons (preventing accidental Xbox button press)

What doesn't work:
- Two of the main buttons (don't work on Windows either)
- The "Haptic" button setting does not have an effect (not sure if it
  works on Windows)

I added the MAP_TRIGGERS_TO_BUTTONS option but in my (limited) testing
there was no practical difference with or without. The FightStick does
not have triggers though so adding it makes sense.

Clement Calmels 93a017aa2f Input: xpad - remove spurious events of wireless xpad 360 controller
When powering up a wireless xbox 360 controller, some wrong joystick
events are generated. It is annoying because, for example, it makes
unwanted moves in Steam big picture mode's menu.

When my controller is powering up, this packet is received by the
driver:
00000000: 00 0f 00 f0 00 cc ff cf 8b e0 86 6a 68 f0 00 20  ...........jh..
00000010: 13 e3 20 1d 30 03 40 01 50 01 ff ff              .. .0.@.P...

According to xboxdrv userspace driver source code, this packet is only
dumping a serial id and should not be interpreted as joystick events.
This issue can be easily seen with jstest:
$ jstest --event /dev/input/js0

This patch only adds a way to filter out this "serial" packet and as a
result it removes the spurous events.

as discussed here[0], x360w is the only pad that maps dpad_to_button.
This is bad for downstream developers as they have to differ between
x360 and x360w which is not intuitive.

This patch implements the suggested solution of exposing the dpad both
as axes and as buttons. This retains backward compatibility with software
already dealing with the difference while makes new software work as
expected across x360/ x360w pads.

Pavel Rojtberg a306a65f46 Input: xpad - remove needless bulk out URB used for LED setup
This code was probably wrong ever since and is redundant with
xpad_send_led_command. Both try to send a similar command to the xbox360
controller. However xpad_send_led_command correctly uses the pad_nr instead
of bInterfaceNumber to select the led and re-uses the irq_out URB instead
of creating a new one.

Note that this change only affects the two supported wireless controllers.
Tested using the xbox360 wireless controller (PC).

Pavel Rojtberg e3b651745a Input: xpad - use ida() for finding the pad_nr
The pad_nr corresponds to the lit up LED on the controller. Therefore there
should be no gaps when enumerating. Currently a LED is only re-assigned
after a controller is re-connected 4 times.

This patch uses ida to track connected pads - this way we can re-assign
freed up pad number immediately.

Consider the following case:
1. pad A is connected and gets pad_nr = 0
2. pad B is connected and gets pad_nr = 1
3. pad A is disconnected
4. pad A is connected again

using ida_simple_get() controller A now correctly gets pad_nr = 0 again.

The xpad wireless endpoint is not a bulk endpoint on my devices, but
rather an interrupt one, so the USB core complains when it is submitted.
I'm guessing that the author really did mean that this should be an

there, let's cover out bases and handle both bulk and interrupt

Takashi Iwai 76460a7bec Input: joystick - use ktime for measuring timing
The current codes in gameport and analog joystick drivers for the time
accounting have a long-standing problem when the system is running
with CPU freq; since the timing is measured via TSC or sample counter,
the calculation isn't reliable.

In this patch, as a simple fix, use the standard ktime to measure the
timing.  In case where no high resolution timer is available,
use_ktime bool option is provided to both modules.  Setting
use_ktime=false switches to the old methods.

Xbox One controllers require an initialization message to start sending

controller does not have LEDs like the Xbox 360 controller, so that
functionality is not implemented. The format of messages controlling rumble
is currently undocumented, so rumble support is not yet implemented.

Note that Xbox One controller advertises three interfaces with the same

Now, why anybody would use that driver no ARM I have no
idea, but Ben Dooks enabled it in the s3c2410_defconfig
along with a bunch of other drivers, even though that
platform has neither ISA nor PCI support. It still
seems to be the right thing to fix this quirk.
