Three things kept Valve's mangoapp from drawing the overlay in a session:
- GLFW 3.4 takes XDG_SESSION_TYPE=wayland with WAYLAND_DISPLAY set as
Wayland-only, and mangoapp needs gamescope's X server; the wrapper sets
XDG_SESSION_TYPE=x11.
- On a Qualcomm display driver it opens a tracefs instance for the GPU memory
total and aborts when that fails, which it always does for an Android app.
The session preload now places the instance in an empty directory of its own
when the real one cannot be made.
- gamescope sends it each frame's timings through a System V message queue,
and Android kernels have no System V IPC. sysv.c now emulates the queue
operations gamescope and mangoapp use, beside its semaphores and shared
memory.
The Quick Access menu's performance overlay toggle and level slider stayed
greyed out: the client exposes SteamClient.System.Perf only with -steamos3,
which SteamOS and Armada pass alongside -steamdeck. Deck mode now launches the
client with both. The session already puts package/beta back to the forced
branch before every start, which keeps -steamos3's own branch switch from
turning into an update loop.
The Deck mode switch moves from the Performance page to the Steam page's
Client settings, next to the client branch it selects by default.
The compositor composed every surface with a blit, which replaces what is under it. gamescope's
Wayland backend hands its overlay and notification planes to the host as full-size translucent
subsurfaces, so a Steam toast, the Quick Access menu or Deck mode's performance overlay blacked
out what was beneath it.
Surfaces whose buffer has alpha and that are not declared opaque now go through an alpha pass
(premultiplied source-over); everything else, and any image the driver cannot sample, keeps the
blit. wl_surface.set_opaque_region is honoured, and only for programs that declare opaque regions
at all, so Wine windows with a meaningless alpha channel are drawn as before. On the SurfaceControl
path a translucent plane is never promoted to the game layer, and the overlay layer is marked
translucent when its plane is.
From WinNative (maxjivi05, feature/wayland-gamescope 69218fc; GPL-3.0), with the SurfaceControl
layer handling added.
Developer options' "Disable child process restrictions" writes only the
feature-flag property persist.sys.fflag.override.settings_enable_monitor_phantom_procs,
never the global setting. Android (FeatureFlagUtils.isEnabled) uses the global
setting when it is set and that property otherwise, but the check read only the
global setting, so a device switched off in Developer options stayed flagged as
unset however often Check again was pressed.
The check now follows Android's order, and the Setup card no longer says "On"
for a setting that is unset or unreadable.
* docs(release): draft 0.2.0 beta notes
* docs(release): credit prs and authors in 0.2.0 notes
* docs(release): add #39 and #45 to 0.2.0 notes
* chore: update readme
* fix(ui): cover the whole screen with the capsule wall
The wall was shifted right and then tilted around its own centre, which
left the bottom-left of the home and loading screens bare. Centre it and
size it to the tilted page's bounding box so every corner stays covered.
* feat(ui): flood from the play button into the throbber
Starting a session from a blue button no longer slides the session up
over the front end. The button stretches out on staggered springs until
the page is the ball's blue, the session opens on that same blue with no
window animation, and the blue gathers into the throbber's ball before
the throbber starts. Re-joining a running session, tiles and reduced
motion keep the old rise.
* docs(release): cover everything since 0.1 in the 0.2.0 notes
0.2.0 is the first release from the org, so list what DroidDeck does
as a whole, grouped by area: org pull requests as #N, pull requests
from before the move as The412Banner/DroidDeck#N, and the early work
that predates pull requests by author. CI and build work gets one
short section instead of a line each.
* docs(release): add screenshots and animations to the 0.2.0 notes
Lead with a game running and a few visual highlights, fold the full
list into collapsible sections by area, and shorten every line to the
feature and its credit. Pre-move pull requests read as legacy#N.
* fix(session): give the desktop its own loading hints
The loading screen's hints were written for Steam, so starting the
desktop or an emulator said the first run downloads Steam and that
leaving the app pauses Steam. Desktop and program sessions now rotate
through hints about the desktop instead.
* fix(build): skip incomplete NDKs when picking one locally
An interrupted sdkmanager install leaves a directory like
28.2.13676358.failed under ndk/, which sorted last and was picked
without a toolchain in it. Only consider directories that carry
source.properties.
* docs(release): show launching straight into Big Picture
* docs(release): credit the launch transition to #46
Twice today a session's Xwayland aborted from one thread ("The futex
facility returned an unexpected error code"), proot lost the tracee, and
the process lived on reparented to init: proot's seccomp filter, with no
tracer left, answers ENOSYS, so Xwayland's main loop logged
"WaitForSomething(): poll: Function not implemented" until something killed
it - 9 GB after Dolphin, 13 GB after PPSSPP. --kill-on-exit and the tree
sweep only reach what proot still traces, and the straggler sweep ran only
at the next session's start.
Now a session stop also kills every process of ours whose executable lives
in the Linux runtime, and bannerlator-session keeps only the first
BL_LOG_CAP bytes (256 MB) of session.log, draining the rest so a writer
that filled it is not killed by SIGPIPE.
Cemu never showed a frame on DroidDeck: its Getting Started dialog blocked
every first launch (the folder picker cannot reach ROMs), the session's
controller helper aborted it, and the desktop's Vulkan renderer drew no
cursor. With the Turnip KGSL fix in the driver and the haptic-optional
Cemu in the catalog, this makes the app side complete:
- bannerlator-pad-defaults seeds Cemu's settings.xml once: the Wii U games
folder, Vulkan, and Cubeb audio on the default device for both the TV
and the GamePad speaker at full volume (Wipeout 3 plays through the
GamePad; Cemu's own default is 20 %).
- The Cemu tile launches full screen (-f).
- libfakeinput.so is preloaded into every session process and exported its
static C++ runtime (~7000 symbols); programs unwound through it and
aborted (shadPS4 in pthread_exit, Cemu's controller thread). Link with
--exclude-libs,ALL, and fail the build if the runtime leaks out again.
- On the Vulkan and GLES desktops the pointer worked but no cursor was
drawn: wlroots hands the cursor to the app's compositor, which draws
none. WLR_NO_HARDWARE_CURSORS=1 makes labwc composite it itself.
Device-tested on the FIT: Super Mario 3D World in-game at 35-37 fps with
sound, Deus Ex HR DC and Wipeout 3 launch with sound; RPCS3, Dolphin and a
Steam session (FlatOut) unchanged on the same driver.
