[PATCH v5 0/4] Input: joystick: xpad: Add X-Box Adaptive Controller support

[PATCH v5 0/4] Input: joystick: xpad: Add X-Box Adaptive Controller support

[Nate Yocom]

Adds support for the X-Box Adaptive Controller, which is protocol
compatible with the XTYPE_XBOXONE support in the driver with two deltas:

 - The X-Box button sets 0x02 as its activation ID, where others set
   0x01
 - The controller has an additional Profile button with 4 active states,
   which this change maps to an Axis control with 4 possible values

Patch series adds device to the supported table, adds support for the
Profile button, and adds support for the X-Box button as distinct
changes.

You probably also want to add it to the absolutes array in
drivers/hid/hid-debug.c.

Again, you might want to wait for confirmation from Dmitry that this is
the right way to do this for the profiles.

Dmitry, could you please confirm whether ABS_PROFILE definition is
correct?

Then Nate can update his patch so we can land the support for that
controller.

Thanks!

Yes, I think this makes sense. Do we have a buy in from userspace folks
(Peter H, etc) for this?

I'd like some documentation added to Documentation/input/event-codes.rst
and potentially to Documentation/input/gamepad.rst even though profile
does not have to be gamepad specific event.

Thanks.

AFAICT, libinput wouldn't use that new axis, simply because it doesn't
care about game controllers.
So it all comes down to game users to validate this (and probably only
android is now the main consumer of these given that SDL and Steam are
directly using hidraw or libusb to talk to controllers).

Benjamin

yep, that's pretty much the summary from my side so ACK from me.

[PATCH v5 3/4] Input: joystick: xpad: Add X-Box Adaptive Controller Profile button

[Nate Yocom]

Adds a new quirk for controllers that have a Profile button which has 4
states, reflected as an ABS_PROFILE axis with 4 values.

Adaptive controller sets 0x02 bit for this button, all others set 0x01
