[PATCH v3 0/1] MR6007: ntdll: Don't use CLOCK_REALTIME_COARSE
by Tatsuyuki Ishi (＠ishitatsuyuki) Aug. 17, 2026

Aug. 17, 2026

This reverts commit 5c8ea25014f ("ntdll: Use CLOCK_REALTIME_COARSE for NtQuerySystemTime() if it has sufficient resolution.") CLOCK_*_COARSE only provides up to 1ms resolution at CONFIG_HZ=1000. OTOH, there are several ways to get up to 0.5ms resolution on modern Windows (high resolution waitable timers, NtSetTimerResolution with 0.5ms). This code path therefore has a possibility of behaving worse than native. Since COARSE resolution is HZ dependent, this code path only runs if the kernel is configured with CONFIG_HZ=1000. Most distro ships does not ship with this. Therefore, this code path is rarely tested, and is more of a recipe for surprise. If any application rely on fast NtQuerySystemTime they are likely already broken for majority of Wine users. Given the above reason, don't use CLOCK_REALTIME_COARSE. Use gettimeofday which is internally hooked to CLOCK_REALTIME. -- v3: ntdll: Don't use CLOCK_REALTIME_COARSE https://gitlab.winehq.org/wine/wine/-/merge_requests/6007

[PATCH 0/2] MR8861: shell32: Accept CSIDL values in SHBrowseForFolderW().
by Attila Fidan (＠atticf) Aug. 5, 2026

Aug. 5, 2026

This fixes an access violation when clicking the button to browse for an installation directory in some installers using the BURIKO (BGI/Ethornell) engine. The affected applications call `SHBrowseForFolderA(&bi)` with `bi.pidlRoot` being 0x11, which causes wine to dereference 0x11 inside InitializeTreeView. On native, this opens the treeview from My Computer. 0x11 is the CSIDL value for My Computer, and passing any pidlRoot from 0 to 2^16 will not crash on native like resource IDs. If an invalid folder value is used then native returns 0 without showing a window. If I delete the My Pictures folder then use `CSIDL_MYPICTURES`, the folder gets recreated. None of this works if `BIF_NEWDIALOGSTYLE` is used, native crashes with access violation. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8861

[PATCH v7 0/2] MR8073: ntdll: Unbreak new wow64 mode on FreeBSD.
by Alexander Shaikhulin (＠shkhln) June 5, 2026

June 5, 2026

1. For %fs/fsbase the patch follows the macOS logic with LDT descriptor registration and Linux with switching. One notable difference is that on 32->64 transition we set %fs to GSEL(GUFS32_SEL, SEL_UPL) before restoring fsbase, otherwise FreeBSD will just revert it by reloading the selector [at the first opportunity](https://github.com/freebsd/freebsd-src/blob/5673462af5330df207…. GSEL(GUFS32_SEL, SEL_UPL) is the default %fs value on FreeBSD and is special-cased to save/restore actual fsbase value to/from PCB. 2. I was told we could get rid of fsbase glitches in signal handlers by blocking signals with [sigfastblock(2)](https://man.freebsd.org/cgi/man.cgi?query=sigfastblock) between %fs reset to the default value and fsbase reset to pthread_teb. This is currently a part of internal API for libthr, which could be exposed as pthread_signal_block_np for Wine. I'm on the fence whether it's worth it. 3. I fully admit I have no idea what registers are worth preserving around fallback sysarch(AMD64_SET_FSBASE) syscalls and whether it's appropriate to push those registers to stack. ("Kernel" stack should be fine, I assume?) Syscalls definitely clobber r8-r11. 4. For %ss see https://lkml.org/lkml/2015/4/24/216. FreeBSD doesn't have a similar workaround in the kernel, so it goes into Wine. -- v7: ntdll: Work around AMD SYSRET SS descriptor behavior on FreeBSD. ntdll: Unbreak new wow64 mode on FreeBSD. https://gitlab.winehq.org/wine/wine/-/merge_requests/8073

[PATCH v6 0/41] MR6207: Draft: include: Introduce new COM implementation helper macros.
by Rémi Bernon June 2, 2026

June 2, 2026

I think it would be very nice to have something like that to reduce the burden of implementing COM interfaces. This shows for instance on the windows.gaming.input module a 30% LoC reduction (from ~6800 to ~4700), even though the module already had a boilerplate helper macros already. The MR introduces macros to automatically implement each IUnknown method, as well as all of them at once. It also includes a helper to implement IInspectable methods at once, as well as macros to forward both interface methods to a base interface or an outer object. Last, it provides higher-level macros to implement a main interface and any number of sub interfaces and generate IUnknown, forwarding and vtables for all of them at once, with IInspectable support when needed. It uses widl to generate additional per-interface macros, for things like inheritance and vtable generation. The rest of the macros are otherwise shared in a Wine-specific header. The implementation is split to show individual macro being used, although they are later replaced by higher-level macros. The individual helpers are still useful in some corner cases where specific behavior needs to be implemented, or for aggregating classes. -- v6: widl: Generate return traces for COM classes. widl: Generate method traces for COM classes. widl: Generate COM class code for IClassFactory. windows.gaming.input: Generate the provider COM class. windows.gaming.input: Generate the vector COM classes. windows.gaming.input: Generate the async COM classes. windows.gaming.input: Generate the manager COM classes. windows.gaming.input: Generate the force feedback COM classes. windows.gaming.input: Generate the ramp effect COM classes. windows.gaming.input: Generate the periodic effect COM classes. windows.gaming.input: Generate the constant effect COM classes. windows.gaming.input: Generate the condition effect COM classes.

[PATCH v3 0/6] MR2298: winewinrt: Introduce new WinRT common module.
by Rémi Bernon June 2, 2026

June 2, 2026

The idea I have is to use this module to declare class stubs until there is a good reason to split them to dedicated modules. WinRT modules aren't usually loaded directly, and instead the registry is queried to figure which module to load for which class. This would help avoiding unnecessary proliferation of stub WinRT modules, while at the same time allowing to factor WinRT foundation code (such as vector / async, etc...) between the modules that seem to deserve to be implemented separately. The relevant classes could then be split out to dedicated modules on a as-needed basis, when they get fleshed out. -- v3: winewinrt: Factor IAsyncOperation<boolean> implementations. winewinrt: Factor IAsyncInfo implementations. winewinrt: Move Vector<HSTRING> from windows.media.speech. widl: Write C type names for function parameters. winewinrt: Factor Vector<IInspectable> implementations. winewinrt: Introduce new static library. https://gitlab.winehq.org/wine/wine/-/merge_requests/2298

[PATCH v14 0/8] MR1074: Draft: ntdll: Improve Valgrind and GDB integration.
by Rémi Bernon May 31, 2026

May 31, 2026

Valgrind support requires a fork, which I've published to https://gitlab.winehq.org/rbernon/valgrind. The fork implements loading DWARF debug info from PE files, instead of the old and broken upstream PDB support. I've tried to upstream these changes a long time ago but didn't receive any feedback. I think we could maybe consider keeping a fork, which I'm happy to maintain, as the changes aren't too large. We may want to investigate adding 32-on-64 support, which may require a bit more changes (to VEX specifically, because its amd64 guest doesn't support segment register manipulation). The changes here are not all related to Valgrind, and I'll create separate MR for those which may make sense independently from Valgrind / GDB. Also included is a suppression file to silent some annoying false positives, many of which are coming from the cross-stack accesses during syscalls, which are confusing Valgrind's stack heuristics. One can try this out with something like: `WINELOADERNOEXEC=1 valgrind --suppressions=tools/valgrind.supp wine64/loader/wine64 wine64/programs/winecfg/winecfg.exe` -- v14: ntdll: Avoid marking freed block header as undefined for valgrind. ntdll: Force HEAP_TAIL_CHECKING_ENABLED flag with valgrind. ntdll: Fix valgrind notifications from ntdll.so. ntdll: Import valgrind headers for PE side ntdll.
