[PATCH 0/9] MR5057: Draft: winewayland.drv: Use virtual display devices to implement mode change emulation
by Alexandros Frantzis (＠afrantzis) 07 Mar '25

07 Mar '25

This WIP branch prototypes the usage of virtual display devices (through "virtual desktop" mode at the moment) to support display mode emulation in the Wayland driver. It works by allowing the driver to mark each host adapter with a virtual_id, which, if present, signals to win32u that it should include the adapter in the virtual display configuration. The virtual configuration (along with the virtual ids) is reported back to the driver though a new user driver function. If none of the host adapters is marked with a virtual id (i.e., all other drivers) we fall back to the single virtual display mode as before. Some deficiencies and open questions with the prototype: 1. Virtual desktop mode implies a lot of behavior that we don't want at this point the Wayland driver (e.g., taskbar window, changing the display mode to the virtual desktop resolution at startup, some changes in fsclip behavior). One way forward would be to have a "virtual display devices" mode separate from the "virtual desktop" mode, so that drivers can opt in only to the desired behavior (virtual desktop would imply virtual devices, to maintain the current behavior). 2. It's not clear to me what would be the best way for a driver to opt in or out of certain core behavior. Perhaps the driver would change some volatile registry key which other components would consult? Or introduce a user driver function for core to query the driver about such features on demand? Is there some precedence I can get inspiration from? 3. At the moment, the prototype calls the new "NotifyVirtualDevices" user driver callback only in the process which the display update occurred. This means that other processes don't get notified of the virtual devices mapping to host devices, so, in the Wayland driver case, we are not able to scale windows from those processes properly. One approach would be for core to ensure that the NotifyVirtualDevices callback is called once in all processes, but I am not sure what's the best way to achieve this (or even if this is the preferred approach). Another way would be to have a mechanism for the driver to query the virtual device info (+mappings) on demand, and just broadcast a message to all windows. In this case it could even be done internally by the driver (so more in line with what the part-12 MR is doing), if we don't want to introduce a more global behavior. Perhaps there is some even better mechanism, which would also be more fitting to how we envision the virtual display/devic es to evolve going forward. Let me know what you think! -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5057

[PATCH 0/5] MR7205: winecrt0: Add builtin functions for msvc/arm mode
by Martin Storsjö (＠mstorsjo) 28 Feb '25

28 Feb '25

Since 9b8409fce4da18e3d9a914a9e5831d10eb9052de, a PE compiler is required for 32 bit arm. That can either be supplied by using plain Clang (from a distro), or llvm-mingw. However when using plain Clang (in MSVC mode), we're lacking compiler builtin functions that either would be provided by MSVC libraries or by compiler-rt libraries bundled in llvm-mingw. Vendor a copy of the relevant files from compiler-rt and include them when building for arm in MSVC mode. This allows building a functional wine for 32 bit arm without requiring third party tools such as llvm-mingw. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7205

[PATCH 0/6] MR7236: winewayland: Clipboard support
by Alexandros Frantzis (＠afrantzis) 28 Feb '25

28 Feb '25

This MR adds clipboard support to the winewayland driver. Under Wayland only applications that have the keyboard focus can interact with the clipboard (a.k.a. `wl_data_device`). Such constraints are not a natural fit for Wine's current clipboard infrastructure, which uses a separate thread and window in the desktop process to act as the win32-side clipboard proxy for all native windows. This MR tries to work within the current Wine clipboard Wine by forwarding relevant clipboard messages to the foreground window which is likely to have the keyboard focus and that can actually handle them. This works well in practice (although there are some edge cases this fails), but I am open to different ideas about implementing the clipboard integration. Some notes about the MR: 1. Some formats that require special treatment (e.g., CF_HTML, CF_HDROP) are not implemented in this MR to keep the size reasonable (and also to not distract from the goal of this MR which is to propose/discuss the basic design of clipboard integration). 2. Dynamic registration of newly-seen/unknown formats is not supported at the moment. It's not clear to what degree that's useful, since many (most?) Windows clipboard format strings are free-form and don't use the MIME type standard. But perhaps enough Windows apps know about MIME types nowadays to make this addition worth it? 3. Since access to the Wayland clipboard data is performed from the focused window threads (rather than the dedicated clipboard thread), any blocking while waiting for data to be sent/received has more potential to affect the applications. I have implemented reasonable timeouts which are hopefully enough to make this a non-issue. A (more complex) alternative would be a different design that attempts to offload any potentially blocking work to the dedicated clipboard thread (or is there some kind of async read/write mechanism we can use?). I am not convinced the extra complexity is worth it, though. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7236

[PATCH 0/3] MR3124: Move periodic registry save out of wineserver
by Paul Gofman (＠gofman) 25 Feb '25

25 Feb '25

The problem is that registry save is a very heavy operation (scheduled each 30sec in wineserver) during which server doesn't process any requests and the whole prefix is stalled for the duration of the operation. For some reference, the process takes from 50-100ms here up to 1-1.5sec with default initial registry (after some registry modifications which trigger actual registry flush), depending on the filesystem type and state (as huge time may be spent in file close / rename). With the same registry after this patchset the server part (flush_key returning the whole registry data) is taking ~4-5mcs, measured from the client side so that already includes data transfer. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3124
