[PATCH 0/1] MR8462: mfmediaengine: Delay old presentation clearing until new toplogy was set.
by Bernhard Kölbl (＠besentv) 30 Jun '25

30 Jun '25

Shutting down the media source, while it is still in an active topology, causes Windows' media session to fully shut down. To avoid this, only clear the old presentation on release, shutdown or when a new topology was successfully set. (FWIW: This solution is definitely not the greatest) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8462

[PATCH v6 0/5] MR8460: ntdll: Add support for multi-battery systems and energy-reporting batteries on Linux
by Tomas-Mendes-ai (＠Tomas-Mendes-ai) 30 Jun '25

30 Jun '25

Current implementation of system.fill_battery_state only reads "charge\__" and "current\__" attributes. Some batteries expose different attributes, namely "power\__" and "energy\__". Added the required logic to support both types. Further, when rewriting the function I also added support for systems with multiple batteries. Windows documentation was not clear but from what I gathered struct SYSTEM_BATTERY_STATE sets Charging and Discharging if ANY battery is charging/discharging. So, to check if the overall system is charging/discharging only Rate can be used. Also cleaned the code related to "AC". There was a "fixme" there which I didn't fully undertand as SYSTEM_BATTERY_STATE.AcOnLine == True if any AC is present, so the proper logic was already implemented -- v6: ntdll: improve readibility of linux_battery capacity units https://gitlab.winehq.org/wine/wine/-/merge_requests/8460

[PATCH v10 0/5] MR8438: cfgmgr32: Device Query API part 1: Add a basic implementation for DevGetObjects.
by Vibhav Pant (＠vibhavp) 30 Jun '25

30 Jun '25

(Follow up from !6788) The goal is to use the device object API as the backend for Windows.Devices.Enumeration, as most concepts from the latter have a one-to-one mapping to the former: * The device object API is centred around the [`DEV_OBJECT`](https://learn.microsoft.com/en-us/windows/win32/api/devquerydef/ns-devquerydef-dev_object) type, which provides a unified representation for devnodes, device interfaces/containers, device interface classes, and association endpoints (networking protocols and service instances, like UPnP and Bluetooth), together with the properties associated with it. The [`DevObjectType`](https://learn.microsoft.com/en-us/windows/win32/api/devquerydef/ne-devquerydef-dev_object_type) enum maps to [`Windows.Devices.Enumeration.DeviceInformationKind`](https://learn.microsoft.com/en-us/uwp/api/windows.devices.enumeration.deviceinformationkind?view=winrt-26100). This would be used to implement the [`DeviceInformation`](https://learn.microsoft.com/en-us/uwp/api/windows.devices.enumeration.deviceinformation?view=winrt-26100) class. * [`DEVPROP_FILTER_EXPRESSION`](https://learn.microsoft.com/en-us/windows/win32/api/devfiltertypes/ns-devfiltertypes-devprop_filter_expression) allows filtering device queries by their properties. AQS filter strings would be parsed into an array of filters, which are then passed to the query object methods. * `DevCreateObjectQuery` would be the backend for `DeviceWatcher`, as it provides asynchronous callbacks for initial device enumeration, device addition, removal and updates. * [`DevGetObjects`](https://learn.microsoft.com/en-us/windows/win32/api/devquery/nf-devquery-devgetobjects) would be used to implement the `FindAllAsync*` methods. This MR adds a basic implementation and tests for `DevGetObjects`. -- v10: cfgmgr32: Add a basic implementation for DevGetObjects(Ex) for device interface objects. cfgmgr32/test: Add tests for DevGetObjects. https://gitlab.winehq.org/wine/wine/-/merge_requests/8438

The `fill_battery_state` code would also be much clearer as a result. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8460#note_108372

Should be fixed now, thanks. Since the returned code in these two cases is `S_OK`, I have set both `len` and `objects` to dummy values to test whether they are correct set to zero/NULL respectively. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8438#note_108361
