[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 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 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

[PATCH 0/2] MR6841: wow64: Support running a BT module provided suspend routine.
by Billy Laws (＠bylaws) May 4, 2026

May 4, 2026

Suspension in JITs cannot easily be handled on the unix side, so allow BT modules to provide their own suspend helper. This purely supports local thread suspension currently. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6841
