[PATCH 0/1] MR10210: kernelbase: Fix GetNativeSystemInfo() in an x86_64 process on ARM64.
by Brendan Shanks (＠bshanks) Feb. 27, 2026

Feb. 27, 2026

In an emulated x86 or x86_64 process on ARM64, GetNativeSystemInfo() should return information as if the native system is x86_64 (assuming x86_64 emulation is supported). This is working correctly for x86 processes, but x86_64 processes are returning PROCESSOR_ARCHITECTURE_ARM64. Fixes test failure when running as x86_64 on ARM64: ``` process.c:2424: Test failed: Expected no difference for wProcessorArchitecture, got 9 and 12 process.c:2427: Test failed: Expected no difference for dwProcessorType, got 8664 and 0 ``` --- I listed all the possibilities to help reason about this. If native_machine is I386: - is_wow64 is FALSE - GetNativeSystemInfo equivalent to GetSystemInfo If native_machine is AMD64, process is I386: - is_wow64 is TRUE - native system info should have processor architecture AMD64 If native_machine is AMD64, process is AMD64: - is_wow64 is FALSE - GetNativeSystemInfo equivalent to GetSystemInfo If native_machine is ARM64, process is ARM64: - is_wow64 is FALSE - GetNativeSystemInfo equivalent to GetSystemInfo If native_machine is ARM64, process is I386: - is_wow64 is TRUE - native system info should have processor architecture AMD64 If native_machine is ARM64, process is AMD64: - is_wow64 is FALSE - GetNativeSystemInfo equivalent to GetSystemInfo -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10210

[PATCH v5 0/8] MR10209: kernelbase/loader.c: Include rudimentary support for multilanguage resource inclusion.
by Craig Schulstad (＠NoDakker) Feb. 27, 2026

Feb. 27, 2026

For programs that rely on language specific data for resources such as menus and text, attempt to search for and associated "mui" file. For example, if program "myapp.exe" is executed and resources are not found, and the user's language ID is "en-US", search for file "en-US/myapp.exe.mui", and if found, utilize that file for the source of resource data. -- v5: Edit loader.c - replaced another tab with spaces https://gitlab.winehq.org/wine/wine/-/merge_requests/10209

[PATCH v20 0/1] MR10192: kernelbase: Handle \\?\ prefix in GetLongPathNameW
by Vishnunithyasoundhar S (＠svishnunithyasoundhar) Feb. 27, 2026

Feb. 27, 2026

The current implementation of GetLongPathNameW triggers a FIXME and returns the original path when it encounters a UNC prefix. While true network UNC paths remain unimplemented, this change allows extended-length local paths (starting with \\\\?) to be resolved by stripping the prefix and processing the underlying local path. This fixes issues where applications (such as xalia) passing absolute paths with the extended-length prefix would fail to receive a normalized or resolved long path. ``` 881.036:00d4:00d8:fixme:file:GetLongPathNameW UNC pathname L"\\\\?\\Z:\\home\\vishnunithyasoundhars\\.steam\\debian-installation\\compatibilitytools.d\\debug_build\\files\\share\\wine/../xalia/xalia.exe" ``` Tested: After change with added debug log ``` 22272.558:00d4:00d8:fixme:file:GetLongPathNameW DEBUG: Success!
