[PATCH 0/1] MR9696: win32u: Workaround a 32-bit llvmpipe crash on initialization.
by Rémi Bernon 05 Dec '25

05 Dec '25

I believe it was crashing already before but this has become more of an issue as the EGL/GL initialization now occurs when loading opengl32.dll unixlib, which prevent any opengl-dependent test to even load. This does not happen with 64-bit unix side, nor does it happen with other drivers, and I suspect this might either be some OOM issue with llvmpipe requiring much more memory, or some bug in llvmpipe initialization. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9696

Re: [PATCH v2 0/1] MR9671: include: Add bti jc for __ASM_DEFINE_FUNC on ARM64

No, we don't want to silently inject instructions at the start of every function, particularly when using SEH. This should be added explicitly on the functions that need it, which at this point probably means only syscall/unixcall dispatchers. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9671#note_124922

IMHO it could be a generic macro so that it can also support x86 CET (endbr64). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9671#note_124919

[PATCH 0/1] MR9695: win32u: Require VK_KHR_external_semaphore_fd for keyed mutexes.
by Rémi Bernon 05 Dec '25

05 Dec '25

We need to use vkImportSemaphoreFdKHR to import the keyed mutex sync object, and it will be NULL if the extension hasn't been enabled. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9695

[PATCH 0/10] MR9687: winebus, hidclass, dinput: Add bus_num and port_path to device_desc and use them in instance_id.
by Ivo Ivanov (＠logos128) 05 Dec '25

05 Dec '25

Use only real serial numbers, otherwise return error on IOCTL_HID_GET_STRING, similar to Windows. Generate consistent container_id (winebus) based on either serial number, uid (macos LocationID), bus_num/port_path (Linux bus_udev) or input/index. Generate consistent guidInstance (dinput) based on device_id/instance_id extracted from the device_path. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9687

[PATCH v9 0/4] MR8505: mfsrcsnk: Implement thinning.
by Charlotte Pabst (＠CharlottePabst) 05 Dec '25

Follow-up to !8184. This also adds a bunch of helpers for writing media source tests (without involving the mf session) in mfsrcsnk, these could be helpful for more tests of this kind in the future. I'm somewhat unsure as to why we haven't done tests for source behavior so far: while those are plugins, applications rely on a bunch of things in the builtin sources that microsoft provides. Since this affects both mfsrcsnk and winegstreamer sources, tests should be run both with `HKCU\\Software\\Wine\\MediaFoundation\\DisableGstByteStreamHandler` enabled and disabled. Due to this I figured it'd make sense to implement everything first and then remove the test todo_wine's and the statements rejecting the thin parameter in a single commit ("Allow thinning"). Perhaps this could be solved more nicely by setting the registry key in the tests themselves? I'm unsure if that is something we do in tests, generally. `MEStreamThinMode` events need to be emitted between the last sample using the outdated thinning parameter and the first sample using the updated thinning parameter. The winegstreamer implementation for this turned out a bit complex, if there is a simpler way to do this please let me know. Regarding winegstreamer, note that buffers need to be intercepted before the decoder because decoders often discard `GST_BUFFER_FLAG_DELTA_UNIT` flags (which is already annoying in itself - it causes all samples to be marked as `MFSampleExtension_CleanPoint`, this should potentially be worked around in the future). But even besides that, intercepting before the decoder is the "proper" implementation, since the point of thinning is increasing decoding speed by skipping delta frames, tho there are some games that rely on the semantics as well. -- v9: mfsrcsnk: Implement thinning. https://gitlab.winehq.org/wine/wine/-/merge_requests/8505
