[PATCH 0/6] MR7250: ntdll: Properly implement NtFlushProcessWriteBuffers (try 2).
by Jinoh Kang (＠iamahuman) Feb. 3, 2025

Feb. 3, 2025

Supersedes !741. On macOS 10.14+ `thread_get_register_pointer_values` is called on every thread of the process. On Linux 4.14+ `membarrier(MEMBARRIER_CMD_GLOBAL_EXPEDITED, ...)` is used. On x86 Linux <= 4.13 and on other platforms it falls back to calling `NtGetContextThread()` on each thread. The fast path patches from @tmatthies are slightly modified in the following ways: 1. On unsupported platforms, the `try_*()` function returns `FALSE` instead of `0`. 2. `try_exp_membarrier()` is called first, then `try_mach_tgrpvs()`. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7250

Supersedes !741. On macOS 10.14+ `thread_get_register_pointer_values` is called on every thread of the process. On Linux 4.14+ `membarrier(MEMBARRIER_CMD_PRIVATE_EXPEDITED, ...)` is used. On x86 Linux <= 4.13 and on other platforms it falls back to calling `NtGetContextThread()` on each thread. The fast path patches from @tmatthies are slightly modified in the following ways: 1.

(rhythm game) song selection menu stuttering - .NET CoreCLR GC - HotSpot JVM (-XX:+UseSystemMemoryBarrier) safepoints -- v2: kernel32/tests: Add a store buffering litmus test involving FlushProcessWriteBuffers. ntdll: Add slow fallback implementation of NtFlushProcessWriteBuffers. https://gitlab.winehq.org/wine/wine/-/merge_requests/7250

[PATCH 0/1] MR7246: wdscore: Don't export C++ symbols.
by Jacek Caban (＠jacek) Feb. 3, 2025

Feb. 3, 2025

Modern Windows versions do not export these symbols. The symbol `??0?$CDynamicArray(a)GPAG@QAE(a)I@Z` uses an unusual mangling scheme that no existing tool understands. This causes issues on ARM64EC, which requires demangling when generating an import library. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7246

[PATCH 0/1] MR7245: ntdll: Implement querying StorageDeviceProperty for optical discs.
by Alex Henrie (＠alexhenrie) Feb. 3, 2025

Feb. 3, 2025

Loosely based on query_property in dlls/mountmgr.sys/device.c. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=57790 The implementation uses memcpy because the program calls DeviceIoControl(STORAGE_PROPERTY_QUERY) with query type PropertyStandardQuery and the output buffer size hardcoded to 8 bytes and expects it to succeed. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7245
