[PATCH 0/1] MR3880: ntdll: Only declare/set wow_teb on platforms using it
by Gerald Pfeifer (＠gerald) 17 Oct '25

Otherwise we see dlls/ntdll/unix/signal_x86_64.c:2351:14: warning: unused variable 'wow_teb' on FreeBSD. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3880

[PATCH v2 0/1] MR411: win32u: Don't load bitmap only TTF fonts without bitmap table.
by Paul Gofman (＠gofman) 12 Oct '25

12 Oct '25

The offending font is NotoColorEmoji.ttf which is present in, e. g., google-noto-emoji-color-fonts or noto-fonts-emoji packages available in various distribution. Attempting to load this font on Windows 10 (with AddFontResourceA() or open it with default font viewer) fails while currently succeeds on Windows. fontforge also refuses to open this font. That is because the font is bitmap only but missing bitmap table. Some apps (Glyph launcher is an example) try to GetOutlineTextMetrics() on this font and do not expect that to have an error return (as we currenly do), which leads to crash on unhandled division by zero exception. I am attaching a bitmap-only ttf test font (with only one bitmap) which I created with fontforge to make sure that such font can still be loaded in Wine. This font also loads on Windows (both with AddFontResourceA() and with default font viewer). There are other font types which can be legitimately missing EBDT table, but FT_Load_Sfnt_Table() returns a different error for those and my patch doesn't reject those fonts.

[PATCH 0/1] MR6140: ntdll: Exclude biggest envars to fit 32767 chars limit in get_initial_environment.
by Martino Fontana (＠tinozzo123) 11 Oct '25

11 Oct '25

Windows has a limit of 32767 characters in the environment block. https://superuser.com/questions/1070272/why-does-windows-have-a-limit-on-en… Wine doesn't attempt to respect that at all. Do some programs actually depend on this? Unfortunately yes. With this patch, during initialization, if the block size would exceed (or be close to) the limit, the biggest environment variables will be excluded. This is useful when a user has very long environment variables in their system for reasons unrelated to Wine. Do note that there's still nothing done to make sure that the limit isn't exceeded after initialization.

[PATCH v2 0/3] MR8760: mmdevapi: Add support for storing/retrieving more variant types from the device property store.
by Connor McAdams (＠cmcadams) 09 Oct '25

09 Oct '25

This has been implemented in a few different ways (see MR !7238 and MR !359), neither of which have associated tests. This way of doing things sidesteps the need to update existing `VT_BLOB` properties by just storing/retrieving them in the same format we always have. If the registry data doesn't match a set of criteria, we treat it as `VT_BLOB` always. -- v2: mmdevapi: Add support for storing VT_CLSID properties. mmdevapi: Add support for storing VT_BOOL properties. https://gitlab.winehq.org/wine/wine/-/merge_requests/8760

[PATCH v3 0/4] MR7570: mfreadwrite: Implement encoder creation. (Part 1)
by Ziqing Hui (＠zhui) 09 Oct '25

09 Oct '25

I split the implementations into 2 parts to make it looks easier to review. So plz first review this MR and make sure it's good so that we don't have to rebase. The follwing patches is in !7571. -- v3: mfreadwrite: Implement sink_writer_SetInputMediaType. mfreadwrite: Implement IMFSinkWriterEx. mfreadwrite: Add converter transform to stream. mfreadwrite: Add attributes member to writer struct. https://gitlab.winehq.org/wine/wine/-/merge_requests/7570

[PATCH v2 0/1] MR5213: Fix Cyberpunk 2077 spawning only one dispatcher thread in FreeBSD
by Katharine Chui (＠katharinechui) 08 Oct '25

08 Oct '25

Normally Cyberpunk 2077 spawns #cpu_threads of dispatcher threads. However with Freebsd, since create_logical_proc_info was a stub, the game would instead spawn a single dispatcher thread, causing the game to just crawl. Working around the issue by adding a barebone implementation of create_logical_proc_info for FreeBSD so that the game would at least get a thread count through ntdll. -- v2: Fix Cyberpunk 2077 spawning only one dispatcher thread in FreeBSD https://gitlab.winehq.org/wine/wine/-/merge_requests/5213

[PATCH v7 0/2] MR8073: ntdll: Unbreak new wow64 mode on FreeBSD.
by Alexander Shaikhulin (＠shkhln) 07 Oct '25

07 Oct '25

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 v3 0/11] MR7869: Thread priority boosts (part 1)
by Marc-Aurel Zent (＠mzent) 07 Oct '25

07 Oct '25

This implements setting `ThreadPriorityBoost`, `ProcessPriorityBoost`, `ProcessBasePriority` and getting `ThreadPriorityBoost`, `ProcessPriorityBoost` NT info classes and adds tests where appropriate. The actual boosting mechanism will be in part 2 to keep the size of this MR manageable. -- v3: kernel32/tests: Add tests for GetProcessPriorityBoost/SetProcessPriorityBoost. kernelbase: Implement SetProcessPriorityBoost. kernelbase: Implement GetProcessPriorityBoost. ntdll: Implement ProcessPriorityBoost class in NtSetInformationProcess. ntdll: Implement ProcessPriorityBoost class in NtQueryInformationProcess. ntdll: Implement ThreadPriorityBoost class in NtSetInformationThread. ntdll: Properly implement ThreadPriorityBoost class in NtQueryInformationThread. ntdll/tests: Add tests for setting process base priority. ntdll: Implement ProcessBasePriority class in NtSetInformationProcess. https://gitlab.winehq.org/wine/wine/-/merge_requests/7869

[PATCH 0/1] MR8430: icu: Add a stub DLL.
by Tim Clem (＠tclem) 06 Oct '25

06 Oct '25

These two functions are enough to get several games running (ScarQuest, Marvel Snap). In the long run I'm not sure how we want to proceed with this DLL. ICU has [a complicated license](https://github.com/unicode-org/icu/blob/main/LICENSE) and is largely C++, so integrating it into wine under `libs/` may be tricky. They do distribute official Windows binaries, and Proton is [repackaging those](https://github.com/ValveSoftware/Proton/tree/proton_10.0/icu) and [adding an icu.dll that forwards to them](https://github.com/ValveSoftware/wine/tree/3e3b24184a29e8e35cd618100f…. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8430
