[PATCH v7 0/2] MR4518: ntdll: Integrate with GDB using r_debug.
by Rémi Bernon June 2, 2026

June 2, 2026

Effectively implementing the debugger interface as described in https://sourceware.org/git/?p=glibc.git;a=blob;f=elf/rtld-debugger-interfac… This is an actual attempt at having this upstream, split from https://gitlab.winehq.org/wine/wine/-/merge_requests/1074 which people have been finding useful for debugging Wine directly in GDB. This supports everything you would expect, from automatic symbol loading as well as cross-syscall backtraces with the new Python unwinder. -- v7: ntdll: Maintain a PE module link map and expose it to GDB. loader: Expose the standard debugging symbols for GDB. https://gitlab.winehq.org/wine/wine/-/merge_requests/4518

[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 v4 0/30] MR2122: Draft: winex11: Support fixed X11 keycode to scancode conversion.
by Rémi Bernon June 2, 2026

June 2, 2026

X11 keycodes are just Linux keycodes + 8 nowadays according to evdev or libinput drivers, and we can avoid innacurate reconstruction in the most common case. Opening this as a draft for now, to show where I'd like to go with https://gitlab.winehq.org/wine/wine/-/merge_requests/2062. -- v4: winex11: Use KbdLayerDescriptor for ToUnicodeEx. win32u: Force US layout in ToUnicode when CTRL is pressed. winex11: Use KbdLayerDescriptor for VkKeyScanEx. winex11: Use KbdLayerDescriptor for MAPVK_VK_TO_CHAR. winex11: Fill the Xkb layout KBDTABLES VkToWchar tables. winex11: Use KbdLayerDescriptor for GetKeyNameText. winex11: Fill the Xkb layout KBDTABLES KeyNames tables. winex11: Use KbdLayerDescriptor for MapVirtualKeyEx. winex11: Create KBDTABLES with VSCtoVK tables for Xkb layouts. winex11: Lookup xkb layout in KbdLayerDescriptor. win32u: Introduce KbdLayerDescriptor user driver entry. winex11: Get rid of now unnecessary EVENT_event_to_vkey. server: Convert CTRL + VK_PAUSE to VK_CANCEL. winex11: Drop now unnecessray nonchar_key_vkey table. winex11: Drop now unnecessary keyboard layout detection code. winex11: Use static scan code to vkey mapping tables. winex11: Support fixed X11 keycode to scancode conversion. winex11: Use scancode high bit to set KEYEVENTF_EXTENDEDKEY flag. winex11: Don't update the keyboard layouts on MappingNotify. winex11: Stop sending WM_INPUTLANGCHANGEREQUEST on MappingNotify. winex11: Send WM_INPUTLANGCHANGEREQUEST when Xkb group changes. crypt32: Avoid using uninitialized memory. winex11: Compute Xkb keyboard layout ID and language. winex11: Keep a list of every known Xkb keyboard layout. winex11: Read the _XKB_RULES_NAMES root window property. winex11: Listen to _XKB_RULES_NAMES root window property changes. win32u: Avoid accessing NULL key name string pointer. win32u: Init vsc2char in NtUserMapVirtualKeyEx only if necessary. win32u: Init vsc2vk in NtUserMapVirtualKeyEx only if necessary. win32u: Init vsc2vk in NtUserGetKeyNameText only if necessary.

[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. DEBUG: ntdll: Don't use preloader when running on valgrind. tools: Add gdbunwind.py script with a syscall unwinder. ntdll: Maintain a PE module link map and expose it to GDB. loader: Expose the standard debugging symbols for GDB. https://gitlab.winehq.org/wine/wine/-/merge_requests/1074
