The Kernel-Mode Driver Framework (KMDF) is a driver framework developed by Microsoft as a tool to aid driver developers create and maintain kernel mode device drivers for Windows 2000 and later releases. It is one of the frameworks included in the Windows Driver Frameworks. The current version is 1.27.

What's New for WDF Drivers in Windows 10 • • 6 minutes to read • Contributors • • In this article This topic summarizes the new features and improvements for Windows Driver Frameworks (WDF) drivers in Windows 10. Windows 10, version 1809 (October 2018 Update, Redstone 5) includes Kernel-Mode Driver Framework (KMDF) version 1.27 and User-Mode Driver Framework (UMDF) version 2.27. Champions of norrath ps2 emulator. You can use these framework versions to build drivers for: • Windows 10 (all SKUs) • Windows Server, version 1809 For version history, see. Except where noted, UMDF references on this page describe version 2 functionality that is not available in UMDF version 1. New in WDF for Windows 10, version 1809 • Added new API New in WDF for Windows 10, version 1803 •. • New in WDF for Windows 10, version 1709 See.

New in WDF for Windows 10, version 1703 In Windows 10, version 1703, WDF includes the following enhancements: • New WDF Verifier settings to detect excessive object creation In some cases, framework objects are incorrectly parented and not deleted after use. With this feature, you can specify a maximum number of objects and what should happen when this threshold is exceeded. To start monitoring, add the following registry values under: HKEY_LOCAL_MACHINE System CurrentControlSet Services Parameters wdf • Add a DWORD value named ObjectLeakDetectionLimit with the threshold value. This is the maximum number of objects of the types described in the ObjectsForLeakDetection key.

• Add a new REG_MULTI_SZ value named ObjectsForLeakDetection that lists each type name to verify. For example, you could specify WDFDMATRANSACTION WDFDEVICE. To specify all handle types, use * as the string. • To control whether exceeding this threshold should cause a debug break or a bugcheck, set the key. By default, if the ObjectsForLeakDetection key is not specified, the framework monitors WDFREQUEST, WDFWORKITEM, WDFKEY, WDFSTRING, WDFOBJECT, and WDFDEVICE.

The limit scales with the number of devices installed, so if the driver creates three WDFDEVICE objects, the WDF Verifier limit is three times the value specified in ObjectLeakDetectionLimit. If you specify WDFREQUEST, the verifier only counts WDFREQUEST objects that the driver creates. This feature does not currently support tracking the WDFMEMORY object type.

• SleepStudy tool provides info on KMDF drivers The SleepStudy software tool reports the number of power references that a KMDF driver has that are preventing the system from going to sleep. For more info, see. The rest of this page describes functionality that was added in Windows 10, version 1507. WDF source code is publicly available • The WDF source code is now available as open source on GitHub. This is the same source code from which the WDF runtime library that ships in Windows 10 is built. You can debug your driver more effectively when you can follow the interactions between the driver and WDF. Download it from.
