SleepStudy tool provides info on KMDF drivers

This feature does not currently support tracking the WDFMEMORY object type. If you specify WDFREQUEST, the verifier only counts WDFREQUEST objects that the driver creates. 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. To control whether exceeding this threshold should cause a debug break or a bugcheck, set the DbgBreakOnError key.īy default, if the ObjectsForLeakDetection key is not specified, the framework monitors WDFREQUEST, WDFWORKITEM, WDFKEY, WDFSTRING, WDFOBJECT, and WDFDEVICE. To specify all handle types, use * as the string. For example, you could specify WDFDMATRANSACTION WDFDEVICE. This is the maximum number of objects of the types described in the ObjectsForLeakDetection key.Īdd a new REG_MULTI_SZ value named ObjectsForLeakDetection that lists each type name to verify. To start monitoring, add the following registry values under: HKEY_LOCAL_MACHINESystemCurrentControlSetServicesParameterswdfĪdd a DWORD value named ObjectLeakDetectionLimit with the threshold value. With this feature, you can specify a maximum number of objects and what should happen when this threshold is exceeded. In some cases, framework objects are incorrectly parented and not deleted after use. New WDF Verifier settings to detect excessive object creation In Windows 10, version 1703, WDF includes the following enhancements: See KMDF Version History and UMDF Version History.

Except where noted, UMDF references on this page describe version 2 functionality that is not available in UMDF version 1. You can use these framework versions to build drivers for:įor version history, see KMDF Version History and UMDF Version History. Windows 10, version 1903 (March 2019 Update, 19H1) includes Kernel-Mode Driver Framework (KMDF) version 1.29 and User-Mode Driver Framework (UMDF) version 2.29. This topic summarizes the new features and improvements for Windows Driver Frameworks (WDF) drivers in Windows 10. WDF supports user-mode (UMDF) and kernel-mode (KMDF.
