[PATCH v4 0/6] MR7250: ntdll: Properly implement NtFlushProcessWriteBuffers (try 2).
by Jinoh Kang (＠iamahuman) 03 Mar '25

03 Mar '25

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. On unsupported platforms, the `try_*()` functions return `FALSE` instead of `0`. 2. `try_exp_membarrier()` is called first, then `try_mach_tgrpvs()`. --- Known applications fixed by this MR: - osu! (rhythm game) song selection menu stuttering - .NET CoreCLR GC - HotSpot JVM (-XX:+UseSystemMemoryBarrier) safepoints -- v4: kernel32/tests: Add a store buffering litmus test involving FlushProcessWriteBuffers. https://gitlab.winehq.org/wine/wine/-/merge_requests/7250

[PATCH v9 0/1] MR7288: winegstreamer: Avoid large buffer pushes in wg_transform.
by Yuxuan Shui (＠yshui) 03 Mar '25

## Context This is a problem discovered when running "Max: The Curse of Brotherhood" under proton. This game writes 4MB a piece into `wg_transform`, which contains about 4 seconds of compressed video. `wg_transform` calls `gst_pad_push` in `transform_ProcessOutput`, which takes \~300ms (i.e. 20 frames @ 60fps) to decode this buffer of video. So the end result is the game hitches every 4 seconds while playing cut scene videos. Proton currently has a special case for this particular game, for which it breaks up the buffer into small chunks to avoid long blocks. This MR adopts that and applies it generally. One concern raised by @redmcg is: > The only issue I can think of is if there are any decoders which don't have a parser; then they might not know how to deal with an arbitrary 4096 byte buffer (the parser is generally responsible for taking arbitrary buffers and producing something the decoder can work with, for example: a full frame). So this MR only enables this strategy when there is a parser element. -- v9: winegstreamer: Avoid large buffer pushes in wg_transform. https://gitlab.winehq.org/wine/wine/-/merge_requests/7288

[PATCH v5 0/1] MR7353: winewayland: Implement SetCursorPos via pointer lock.
by Attila Fidan (＠atticf) 02 Mar '25

02 Mar '25

There is no ([not yet?](https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requ…) dedicated protocol for requesting pointer warps, but it's possible to request one with `zwp_locked_pointer_v1.set_cursor_position_hint` which may be performed when the pointer is unlocked. The idea is to quickly lock/set position/unlock. This is used by SDL (in some cases: [SDL_MOUSE_EMULATE_WARP_WITH_RELATIVE](https://wiki.libsdl.org/SDL3/SDL_HINT…) and Xwayland. The limitation is/will be that the compositor will ignore requests to warp the pointer outside of surface bounds. What I'd like to have working is the auto cursor placement feature of some applications, where they just want to call SetCursorPos towards specific UI elements inside their single window, and usually they'll be unclipped and have a visible cursor while doing this. This patch also happens to allow mouselook to work in applications which use SetCursorPos for mouselook and aren't getting covered by the heuristics that turn on Wayland relative motion (for some reason the driver thinks the cursor is visible). Seems to affect Half-Life (GoldSrc) on my system. Though force enabling relative motion with an environment variable in a custom build or somehow improving the heuristics will also fix that. ~~A suface/pointer can only have one lock or confinement, and this implementation depends on the pointer lock. So if needed, I temporarily unlock/unconfine in order to do the warp then relock/reconfine. I modified `wayland_pointer_update_constraint` so I don't have to temporarily disable relative motion during this in case it's enabled. I think it's safe/a no-op to attempt pointer warps while using relative motion, as according to the protocol the warp will not generate a relative motion event, and while there will be a wl_pointer motion event, they're ignored while relative motion is being used.~~ -- v5: winewayland: Implement SetCursorPos via pointer lock. https://gitlab.winehq.org/wine/wine/-/merge_requests/7353

[PATCH 0/1] MR7444: make_unicode: Generate the PostScript builtin font metrics.
by Alexandre Julliard (＠julliard) 01 Mar '25

01 Mar '25

This is an attempt at generating the font metrics from publicly downloadable data. The Windows metrics are generated from the AFM sources instead of being copied from some unrelated TrueType fonts as done in a3b562f74eeb6a5abc3013e57ff489107677b743. It's not clear if that matters, neither seem to match the values on Windows. It would be possible to simplify things further, and to use more up-to-date source data, but for now the goal is to minimize the diff to the generated files. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7444
