* feat: stand in for /dev/uinput so Steam Input's virtual pads reach games
* feat: present the pad to the Steam client as a Steam Deck controller over hidraw
* docs: log the uinput stand-in and the Steam Deck controller
* feat: feed the handheld's gyro and accelerometer to the Steam Deck controller
* feat: let the Steam page choose between the Steam Deck controller and the Xbox 360 pad
* feat: Deck back grips and trackpads on the second screen
* fix: serialize ring teardown with its writers, fall back to the Xbox pad when the Deck cannot be set up, and read motion only for a Deck
* fix: keep the second screen's choice through sleep and bring it back on wake
The on-screen pad is now placed from the panel's physical size: the
sticks and face buttons sit at the two-thumb rest point (about 17% of
the width inboard, 28% of the height up, clamped in millimetres), with
the d-pad and right stick below-inboard, shoulders above, and nothing
ever placed off screen or under a display cutout. Button sizes are
unchanged.
Setup > Controller holds the on-screen controls mode, a tint (Steam
blue #1A9FFF by default), opacity, button size, stick click (double-tap
for L3/R3), a full-screen layout editor, per-button mapping including
LT/RT, and resets for each.
Also from WinNative #772: the fakeinput ring poll backoff is capped at
2 ms instead of 16 ms, the session asks for unbuffered joystick input,
and the on-screen controls request unbuffered dispatch per gesture and
release everything when detached. The QAM button no longer draws at the
top-left corner in full-pad mode.
App name, app ID and code package: DroidDeck, com.droiddeck.launcher
(sources moved to com/droiddeck/launcher, the 68 JNI functions renamed
with them). The new app ID installs beside SteamDeck rather than over it.
Everywhere the name was the app's own: the sidebar title, the session
report, share zips, the shell title, wake-lock and log tags, User-Agents,
the Compose theme, the Download folder and switch files (droiddeck-env,
-osc, -driver, -tu-debug, -no-pad, -pad-log, -no-hud, -wlr-renderer; the
old names are not read), and inside the runtime (droiddeck-desktop,
Firefox's droiddeck.js, the shortcuts tag, the rumble socket, debug and
cache paths). Build scripts, CI artifact (droiddeck-apk), CMake project,
README and the progress log follow.
Kept on purpose: Valve's Steam Deck (the -steamdeck flag,
steamdeck_publicbeta/stable, 'Steam Deck mode', the steamos.cloud
package URLs) and names inside the hosted desktop package (steamdeck.png,
steamdeck-steam, steamdeck-bigpicture). 'Desktop installed' now tests for
labwc instead of the launcher the app stages itself. A committed
__pycache__ .pyc is removed.
The five files the audit measured as Winlator's are replaced: a one-method callback interface by
java.util.function.Consumer, the component base by SessionPart (attach an application context,
start, stop), the environment list by HostEnvironment, the process starter by HostProcess, and
the pad's state holder by PadState with named sticks, triggers, directions and buttons. The
frame-generation tree is framegen/ (its contents were never Winlator's: lsfg-vk's port and
Bannerlator's Win-FG), the log tags are the app's, and the fake pad's rumble socket is now one
the app actually serves: RumbleComponent turns a game's force-feedback effects into the phone's
vibrator, which used to go nowhere. The two design notes describing Bannerlator's X11 path are
gone, and the README and credits say what is whose.
From Bannerlator's feat/linux-gamescope-runtime since this repo was cut:
- Session teardown (4509d788): proot was SIGKILLed, which never lets its
--kill-on-exit cleanup run; its tracees lived on with no tracer, every
seccomp-trapped syscall failing with ENOSYS, spinning at a full core for over
an hour. Now SIGTERM, a grace for proot's own cleanup, SIGKILL only if it
will not go, then a sweep of the tree it had — snapshotted first, each pid
checked against its start time.
- The Steam client's controller interposer is its own source
(fakeinput_steam.cpp, 28922e7c), separate from the one preloaded into Wine.
- The seeder runs on a beat so a prefix the client creates mid-session is
covered before its install scripts run (6ee86bff).
- GE-Proton and proton-cachyos as compatibility tools: the registrar
bannerlator-proton-extra and the compat script's adopt_extras (03867656).
- space.c in the session shim: a library's own free space, not the phone's.
The env-vs-args ordering bug (98d38931) does not apply here: nothing is added
after the script name.
