| | | | | | | | | | | | | | | | | | | commit b6fc513da50c5dbc457a8ad6b58b046a6a68fd9d upstream. currently the controllers get the same product id as the wireless receiver. However the controllers actually have their own product id. The patch makes the driver expose the same product id as the windows driver.

| * Input: xpad - power off wireless 360 controllers on suspendCameron Gutman2016-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Input: xpad - prevent spurious input from wired Xbox 360 controllersCameron Gutman2016-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: Cameron Gutman <aicommander@gmail.com> Signed-off-by: Pavel Rojtberg <rojtberg@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | abs() function can not be used with 64 bit values, so let's switch to abs64(). From include/linux/kernel.h: /* * abs() handles unsigned and signed longs, ints, shorts and chars. * For all input types abs() returns a signed long. * abs() should not be used for 64-bit types (s64, u64, long long) * - use abs64() for those. */ Reported-by: Joe Perches <joe@perches.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
