Proton Wine Build based on Valve Wine

Proton Version: 11.0-2

Built from commit: d67ac1e

Architectures

• x86_64 (Intel/AMD 64-bit)
• arm64ec (ARM64EC)

Single SDK 28 build with 16KB page size support (works on Android 9+ and Android 15+).

Features

• Runtime ntsync backend selection: kernel /dev/ntsync when present and usable (probed by wineserver at startup), otherwise experimental userspace ntsync via ntsync-android (commit 7ce6435) — plus fsync and wineserver-side ntsync_event_set support; PROTON_NO_NTSYNC=1 disables ntsync entirely
• WINE_FAST_YIELD fast-yield hook in NtYieldExecution
• FEX integration (stats shm, SkipThreadAttach detach guard) via bylaws' arm64ec patches
• FEX unixlib loader: MemoryWineLoadUnixLibByName / wow64 / unload support with $PREFIX/lib/wine fallback
• WINEVMEMMAXSIZE virtual-address cap for FEX environments
• Integrated lsteamclient built into Proton (supports GameNative bionic Steam)
• Stripped, -g0 -O2 build: smaller tree, faster install (zstd-packed .wcp)

ntsync changes in this build

• Runtime kernel/userspace backend detection (proton-wine side) — ntsync is no longer hard-selected at compile time. wineserver probes /dev/ntsync at startup with a real NTSYNC_IOC_CREATE_EVENT ioctl (catches SELinux/seccomp-blocked nodes): if the kernel driver is present and usable it is used directly; otherwise the build falls back to the userspace ntsync-android shm backend. Backend is chosen once per session and applies to all processes.
• No shm region on kernel-ntsync devices — the dead-process sweep is now gated on the userspace backend being active, so the ~960 KB shm file is never initialized when the kernel driver handles ntsync.
• ntsync-android library is unchanged since the last build (7ce6435); PROTON_NO_NTSYNC=1 still disables both backends.

Android / bionic fixes

• Anonymous PE-image mapping for bionic (vc4 devices); LC_ALL=C.UTF-8 default; shell32 drive-root path fix
• Android clipboard bridge (user32/win32u) and Android URL/intent launching in winebrowser
• dnsapi libresolv bionic port; nsiproxy interface/route enumeration without netlink; ws2_32 socket tweaks
• winepulse audio period fix, MIDI mapper rework, SDL gamepad init fixes
• winex11 window/keyboard/mouse/GL/desktop tweaks; explorer desktop sizing; GetUserNameA on Android

Compile optimizations (ccache, -g0/strip, zstd packaging) and runtime improvements — WINE_FAST_YIELD fast-yield, FEX unixlib loader, WINEVMEMMAXSIZE VA cap, vc4 bionic fixes (anonymous PE mappings, LC_ALL=C.UTF-8, shell32 drive-root fix), and xrandr/xrender enablement — are adopted from The412Banner/proton-wine release build-p11-20260821 (merged in commit b08376b).
