The native arm64 client follows steamdeck_publicbeta, so a Valve beta
regression reaches every user at once. If the repaired beta client is still
started twice without being shown, or the beta manifest carries no arm64
client, droiddeck-steam-install now installs steamdeck_stable, keeps it, and
logs why (listing the manifest's blocks in the second case). The session asks
the installer for the channel, so -clientbeta and package/beta stay in sync.
BL_STEAM_CHANNEL or ~/.config/droiddeck/steam-channel (beta|stable) pins it.
Valve's 2026-10-15 beta moved the x86 client into a Steam Runtime container.
In case the arm64 client follows, its session now exports
STEAM_STEAMRT_RECURSION_GUARD=1 and, only if steamrtarm64 carries pv-runtime
or a steam-runtime-check-requirements probe, starts it through the same
steamrt shim the x86-64 client uses (now droiddeck-steamrt-shim) and logs it.
Wine asks for userfaultfd with the i386 syscall number on arm64, so it
never gets one and falls back to mprotect and a SIGSEGV per first write,
which under proot is a ptrace stop each time. libblsession hands it the
real userfaultfd and, where Android refuses the PAGEMAP_SCAN ioctl, answers
it from /proc/self/pagemap and UFFDIO_WRITEPROTECT.
PipeWire's access module checks each client's /proc/<pid>/root for a
Flatpak marker. Where that lookup fails under proot (seen on a nubia
NX809J), PipeWire treats the client as sandboxed and holds it until the
session manager grants permissions, and WirePlumber, itself held, never
does. gamescope then waits forever for its capture stream and never
starts Steam: a black screen until the session is closed.
The session's PipeWire now gives both of its sockets unrestricted access
and WirePlumber keeps those clients at full permissions, so nothing
depends on that lookup.
perf: files in an SD card library resolve through the fast path instead of proot
A library bound at several guest names (droiddeck-sd, bannerlator-sd and
case variants) made every symlink and /proc/self/fd readlink under it fall
back to proot. The fast path now orders its binds the way proot does and
gives each host path the name proot would, and lstat("link/.") follows
the link as the kernel does.

Select the explicitly configured Android render node for nested KWin 6.8, apply OpenGL settings before Plasma starts, and pin the original signed Mesa 26.2.4 package that passed Thor rendering. Remove build-directory runtime search paths and fail closed on ELF inspection errors.
Native ARM64 build passed. Thor validated a visible nested Wayland terminal, active OpenGL ES/Zink on Turnip, 1280x720 output, and keyboard input. Mesa pin regression tests, launcher and ELF failure controls, shell syntax, and human authorship checks passed. Published desktop pin remains r2; full latest-head CI is pending and maintainer authorized this merge after device validation.
Match the native builder and desktop package override to Arch Linux ARM KWin 6.8.0, pin the official source hash, and port the nested-scaling patch. Check package/source version consistency in both build jobs.
Official source checksum, patch application, live package closure, and shell syntax verified. The published desktop remains pinned to r2; candidate 6.8 device/rendering validation remains pending before any package publication.
Combine trusted source and squash-metadata validation with the exact-head APK compilation result. Preserve automatic trailer cleanup in the installed hooks.
Validated with 10 authorship/hook tests and 9 combined-gate tests.
Install commit and push hooks that remove bot co-author trailers, preserve human credits, and reject bot primary authors. Add a trusted default-branch CI checker and publish its required status on the exact proposed commit. Validate main pushes as well. Ten regression tests pass, including real Git hook tests and the --no-verify case.
* feat: tools/device-smoke.sh checks a build on a real device over plain adb
Installs and launches the app, changes the density and the window size, cycles a foldable's device state, then reads the newest debug session (first frame, last frame rate, memory page size, process exits). It restores the display and the device state it changed. No python needed; complements tools/droiddeck-scenario, which drives games.
* fix: device-smoke.sh restores only what it changed and checks more carefully
Restore the device state by cancelling the override the script made, or
by putting back the override that was already pinned (a test lab pins
one), instead of pinning the committed state. Restore density and size
only after the script changed them. Keep adb's exit status, count only
crashes of the tested app and fail when the crash buffer cannot be read,
compare the top activity after the density change, and exit 2 when an
option value is missing.
* fix: check wm density/size exit statuses and keep restore flags on failure
* fix: verify smoke-test display changes and restoration
* fix: reject false smoke-test launches and quote remote paths
* Run final display cleanup before reporting smoke results

The == STEP lines in session.log now read HH:MM:SS.mmm, so the setup
steps before Steam starts can be timed; with whole seconds most of them
showed the same time.

* Run FEX-tool games on the chosen game cores
Performance > Game cores reached only the Proton launchers: games started
through "Linux x86 (FEX)" ran on every core, including the slowest cluster.
* Test that SteamVR FEX launches keep the game cores
* perf: FEX's in-root path lookups go through the fast path instead of proot
Android has no openat2, so libblsession walks RESOLVE_IN_ROOT lookups for
FEX one component at a time. Every fstatat, readlinkat and openat in that
walk was a raw syscall that stopped in proot. When libblfastpath is loaded,
the walk now calls its fstatat, readlinkat and openat, which answer without
proot and fall back to the raw syscall themselves. Without it the walk uses
the raw syscalls as before.
One lookup drops from 250-940 us to 26-86 us. A Graveyard Keeper launch
makes 37.5k proot stops instead of 54.0k and reaches its first scene
0.31 s sooner.
* test: count fstatat64 where the preload asks for it
* perf: FEX's own file opens go through the fast path instead of proot
FEX opens host files for the game with syscall(SYS_openat), so every one
stopped in proot even when the fast path could answer it. libblsession's
syscall() now sends SYS_openat to the fast path's openat as well, the same
way the in-root walk does, and makes the raw syscall when the fast path is
not loaded.
A Graveyard Keeper launch makes 28.0k proot stops instead of 37.5k; FEX's
openat stops go from 6,739 to none.
* fix: the fast path's start-up reads don't come back through syscall()
libblsession's syscall() now sends SYS_openat to the fast path. A process
named FEX starts the fast path by reading /proc/self/cmdline with
syscall(SYS_openat), which came straight back into the fast path and
waited on its own pthread_once. Its start-up reads now call libc's
syscall directly.
A process's status read for another process is served read-only, so
Chromium's ReadOnlyFile check no longer kills the browser. Chromium-based
AppImages without chrome-sandbox get --no-sandbox, and Flathub Chromium and
Electron apps skip zypak's spawn portal, which cannot work here.
* perf: performance overlay updates ride the next game frame instead of an extra composite
* gamescope: a held overlay repaint is only cleared once an output was painted
* gamescope: release.env points at p12

* feat: hardware Remote Play encoding through MediaCodec behind Steam's V4L2 stage
* feat: deliver Remote Play touches to gamescope as touches
* feat: route game audio through PulseAudio while a Remote Play client is connected

FEX launched through a script (Valve's _v2-entry-point) was judged 32-bit, so the
fast path stayed off in the FEX client while FEXServer bound its socket through it.
The fast path now follows #! lines before judging the program.
The live compat sync drops apps the client refuses GetCompatTools for instead of
reattaching forever.
