PATCH 1/1 Input: xpad - add Lenovo Legion Go controllers

When the controllers are both attached (or detached), they appear as 0x17ef, 0x6182. When only one is attached, they appear as 0x17ef, 0x6184.

84 (mixed attachment) is already recognized as a gamepad by Linux. This patch adds 82 (both attached/detached).

These controllers have many more buttons than is typical. With this patch, here's what's functional when it presents as 82:

Recognized:

- X, Y, A, B
- both analog sticks, including L3/R3
- D-pad
- menu and capture buttons
- rumble

Not yet recognized:

- start, select
- 4 rear paddle buttons (Y1, Y2, Y3, M3)
- gyroscope

(There are also non-functional buttons when reporting as 84 that are out-of-scope for this patch.)

It looks like your workflow of copy-pasting this into your email client has turned the tabs in the patch into a single space character.

This and possibly other issues (line-wrapping, wrong end-of-line type) is why using git send-email is the preferred way to submit kernel patches.

Maybe try using Brenton Simpson <[email protected]>

for both the author and signed-off-by fields and then use git send-email ?

Regards,

Hans

p.s.

Might be best to send the next attempt just to me, until you've figured out a working email setup. And then once we have things working, re-submit to the right people ?

PATCH 1/1 Input: xpad - add Lenovo Legion Go controllers

In reply to Brenton Simpson

The Lenovo Legion Go is a handheld gaming system, similar to a Steam Deck. It has a gamepad (including rear paddles), 3 gyroscopes, a trackpad, volume buttons, a power button, and 2 LED ring lights.

The Legion Go firmware presents these controls as a USB hub with various devices attached. In its default state, the gamepad is presented as an Xbox controller connected to this hub. (By holding a combination of buttons, it can be changed to use the older DirectInput API.)

This patch teaches the existing Xbox controller module xpad to bind to the controller in the Legion Go, which enables support for the:

- directional pad,
- analog sticks (including clicks),
- X, Y, A, B,
- start and select (or menu and capture),
- shoulder buttons, and
- rumble.

The trackpad, touchscreen, volume controls, and power button are already supported via existing kernel modules. Two of the face buttons, the gyroscopes, rear paddles, and LEDs are not.

After this patch lands, the Legion Go will be mostly functional in Linux, out-of-the-box. The various components of the USB hub can be synthesized into a single logical controller (including the additional buttons) in userspace with [Handheld Daemon](https://github.com/hhd-dev/hhd), which makes the Go fully functional.

#5 lore raw

Thanks Vicki. I didn't realize they were meant to be sorted.

Would it be appropriate to add comments explaining the sorting? The second stanza, in particular, is sorted by the IDs rather than lexicographically. If someone sorted it naively, they'd end up with a bigger diff than expected.

It looks like a few others have escaped sorting; for instance, "Microsoft X-Box One Elite 2 pad" appears in the wrong place.

If Dmitry wants to land this and then follow on with a sort + comment commit (or do that first and then rebase this on top), that would be great. I can take a stab too if that's helpful.

Yes, we usually sort by VID/PID rather than the name of the device.

I applied the patch (moving the entires to the right place). If someone would send a patch fixing the Elite 2 entry and noting the sorting rules I'd be happy to apply it.
