[Feature request] Implement Steam Deck Gyro Support Using a DSU Server
Quick summary
Follow Up of an RPCS3 Issue and PR: https://github.com/RPCS3/rpcs3/issues/8600 and https://github.com/RPCS3/rpcs3/pull/12502
Could RPCS3 implement Steam Deck Gyro support using SteamDeckGyroDSU: https://github.com/kmicki/SteamDeckGyroDSU?
SteamDeckGyroDSU adds a buddy DSUClient to the control input list and allows these emulators to properly use the Steam Deck's gyro.
Details
I am using the RPCS3 AppImage, Build 0.0.26-14525, on the Steam Deck, SteamOS, an Arch based linux distribution. More detail here: https://wiki.archlinux.org/title/Steam_Deck.
Preface
I followed the instructions here: https://github.com/RPCS3/rpcs3/issues/12503, added the deck
user to the input
group, restarted the Steam Deck, and gyro does seem to pop up as a buddy device as described in the issue linked.

However, gyro does not seem to be exposing properly and is not actually enabled in game. I've been using Folklore as a test. I am not sure if the Motion Controls
menu is part of it but here's a photo of that screen (there is nothing available in the drop-down menu):
Other emulators, Dolphin, Cemu, Yuzu, and Ryujinx, all are able to use SteamDeckGyroDSU to properly expose gyro to the emulator: https://github.com/kmicki/SteamDeckGyroDSU.
SteamDeckGyroDSU implementation works similarly to the RPCS3 implementation of gyro linked in the issue above.

It would be great if RPCS3 could somehow take advantage of SteamDeckGyroDSU and add gyro support for the Steam Deck.
Please describe, what part of RPCS3 would be affected by your feature:
It would be an expansion of the PR here: https://github.com/RPCS3/rpcs3/issues/12503, adding gyro support for the Steam Deck.
Please tell us, why your feature is important to RPCS3
To properly implement Steam Deck gyro support, expanding gyro support for an additional group of users.
Please attach screenshots of the feature implemented in other projects

Missing log file 🥱
I'd be happy to get a log file, it wasn't specifically a game-related issue so I wasn't sure how. What log file are you looking for?
well. one where you try to configure it for example.
The only output I get from the log is:
E evdev: evdev TestVibration: Device [FTS3528:00 2808:1015] does not support rumble features! [large_motor = 0] [small_motor = 0] x6
you're supposed to upload the log file
I'm sorry, could you clarify how I get this log file?
The error message above is from clicking View
, and clicking Show Log/TTY
.
Has there been any attention given to this?
It's currently impossible to play games that require motion controls on the SteamDeck despite the device supporting gyroscopic controls. Other emulators have implemented support for SteamDeckGyroDSU as a solution. It would be a nice feature for this project as well.
As for logs, there are none as support for the requested feature simply doesn't exist and therefore there is nothing to log.
Hopefully this can be introduced at some point as also stuck on Folklore on the deck.
Can someone please make this happen. That's just silly that you guys expect people to plug in a ps3 controller into the steam deck and play that way.
Everyone is welcome to make a pull request
I saw that reWASD implemented pressure-sensitive touchpads of Steam Deck and it's possible to emulate there virtual DualShock 3. Gyro is emulated in virtual controllers too. It can be a workaround for the problem, but it would be nice to be able to use Steam Deck's pressure-sensitive touchpads natively via DSU Server or SteamInput.
SteamInput has the ability to set thresholds for trackpad press, so I think it's possible to achieve a similar thing by adding the three thresholds (not the only one) of pressure-sensitivity, but gyro probably will need DSU Server anyway.
Any updates to this since Aug? No one working on this behind the scenes?
Seems the feature was already implemented in #12503 so I don't understand why it isn't working on the steam deck. Does anyone have a workaround? I realy want to play Folklore :(
Any news about this?
At this point I'm willing to put up some kind of bounty to have this feature in RPCS3. It's the biggest flaw of this emulator on Steam Deck right now.
