[PATCH v2 0/19] MR7516: Server-side thread priorities implementation (Part 3)
by Marc-Aurel Zent (＠mzent) 07 Mar '25

07 Mar '25

This is the continuation of https://gitlab.winehq.org/wine/wine/-/merge_requests/7317. There are a lot of smaller commits (some even no-op renames), because there are some inconsistencies in the codebase currently of what an NT thread priority vs a base thread priority should be and I hope that this clears that up a bit. I tried making the commits as atomic as possible I hope this is fine... There are still a few tiny details missing like fixing up the `list_processes` request and `KeSetPriorityThread` and friends which are either stubs or not correctly working as well. There are also probably a few tests that can be written here (after thread priority boosting has been disabled, cause that makes the behavior on windows very flaky and dynamic). In fact on windows there is some thread priority boost decay going on after the message has been processed (and probably other boosting mechanisms), which this MR does not properly capture, but are also probably not reasonable to implement. This also reverts the commits of https://gitlab.winehq.org/wine/wine/-/merge_requests/1232, which are being effectively overwritten anyways. The `get_thread_priority_info` request was added, because the reply in `get_thread_info` would be otherwise larger than 64 bytes, so it had to be split. -- v2: Revert "ntdll: Set the QoS class of the main Wine thread on macOS." Revert "ntdll: Fix runtime availability check for pthread_attr_set_qos_class_np." This merge request has too many patches to be relayed via email.

[PATCH 0/1] MR7522: user32/tests: Make failures in sysparams test less likely.
by Bernhard Übelacker (＠bernhardu) 07 Mar '25

07 Mar '25

The [user32:sysparams patterns page](https://test.winehq.org/data/patterns.html#user32:sysparams) shows plenty of failures with Windows 10. Running [a single machine](https://testbot.winehq.org/JobDetails.pl?Key=151682) test did not show such a failure. Therefore the idea is there is some race condition, which shows up when testbot has more load, like in the batch runs. While there was still a batch run active, [I received with a null change](https://testbot.winehq.org/JobDetails.pl?Key=151697) the failures quite reliable. [Adding some Sleeps](https://testbot.winehq.org/JobDetails.pl?Key=151698) seems to improve the situation. This Sleeps would add 4 seconds to each test run. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7522

[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 v2 0/2] MR7493: mp3dmod: Implement an IMFTransform interface.
by Brendan McGrath (＠redmcg) 07 Mar '25

07 Mar '25

This MR adds the IMFTransform interface to the mp3dmod module so that it can be used as an MFT. It also calls `MFTRegister` (so the MFT can be found via `MFTEnum`) and also registers a byte stream handler for the mp3 format. -- v2: mfsrcsnk: Register the MP3 Byte Stream Handler class. mp3dmod: Implement an IMFTransform interface. https://gitlab.winehq.org/wine/wine/-/merge_requests/7493

[PATCH v2 0/3] MR7416: wined3d: Interpret Y'CbCr values as being from the reduced range.
by Elizabeth Figura (＠zfigura) 07 Mar '25

07 Mar '25

This is an adjustment of 7324. d3d9:visual already has a test that's relatively close to what a simplified version of the tests in 7324 looked like, so I made the few changes to expand that test to match and then ported it to ddraw. Implementation-wise, this removes the SD/HD difference (which only exists on NVidia and is not necessary to improve the mentioned application). It also removes the clamping of YUV values, which as the tests show is not correct. -- v2: wined3d: Interpret Y'CbCr values as being from the reduced range. ddraw/tests: Port yuv_layout_test() from d3d9. d3d9/tests: Expand the YUV blit tests a bit. https://gitlab.winehq.org/wine/wine/-/merge_requests/7416

[PATCH 0/2] MR7519: ntdll: Stop using chdir() in file_id_to_unix_file_name().
by Brendan Shanks (＠bshanks) 07 Mar '25

07 Mar '25

It seems like a good thing to avoid changing the process working directory, and the *at() functions are available on all recent OSes (macOS being the laggard, didn't add them until 10.10). I'm planning to do this elsewhere in `ntdll/unix/file.c` as well. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7519
