If you turn on the IFR in your driver binary, the IFR is present and running during the lifetime of your driver. If a driver crashes, the logs are frequently included in the crash dump file. The IFR maintains a circular buffer of WPP traces in non-pageable memory. See Inflight Trace Recorder (IFR) for logging traces and Using Inflight Trace Recorder in KMDF and UMDF Drivers. Note that the new driver IFR log is separate from the framework IFR log that WDF creates for each driver. When a driver provides a custom trace, the driver IFR log contains the trace messages.

Want to benefit from the universal capabilities of UMDF 2? To learn how to port your old UMDF 1 driver, see Porting a Driver from UMDF 1 to UMDF 2. Note that UMDF 1 drivers run only on Windows 10 for desktop editions and earlier versions of desktop Windows.

Universal Driver ComplianceĪll WDF driver samples and Visual Studio driver templates are Universal Windows driver compliant.Īll KMDF and UMDF 2 functionality is Universal Windows driver compliant. For more information, see Debugging with WDF Source and Video: Debugging your driver with WDF source code.

You can use this feature to step through the WDF source code while debugging, and to learn about framework internals without downloading the source code to a local machine. When you use WinDbg to debug a WDF driver on Windows 10, WinDbg automatically retrieves the framework source code from Microsoft's public GitHub repository. Īutomatic Source Level Debugging of Framework Code The Windows Driver Kit (WDK) 10 samples are also now published to GitHub. The private symbol files for WDF on Windows 10 are now available through the Microsoft Symbol Server. You can debug your driver more effectively when you can follow the interactions between the driver and WDF. This is the same source code from which the WDF runtime library that ships in Windows 10 is built. The WDF source code is now available as open source on GitHub. The rest of this page describes functionality that was added in Windows 10, version 1507. For more info, see Modern standby SleepStudy.

The SleepStudy software tool reports the number of power references that a KMDF driver has that are preventing the system from going to sleep. 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. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\\Parameters\wdfĪdd a DWORD value named ObjectLeakDetectionLimit with the threshold value. To start monitoring, add the following registry values under: 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:
