When a driver provides a custom trace, the driver IFR log contains the trace messages.
KERNEL MODE DRIVER FRAMEWORK 1.11 WINDOWS 7 DRIVERS
Debugging and DiagnosabilityĪll KMDF and UMDF 2 drivers can use an always on, always available Inflight Trace Recorder (IFR).
KERNEL MODE DRIVER FRAMEWORK 1.11 WINDOWS 7 HOW TO
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.
KERNEL MODE DRIVER FRAMEWORK 1.11 WINDOWS 7 WINDOWS 10
Note that UMDF 1 drivers run only on Windows 10 for desktop editions and earlier versions of desktop Windows. Kernel Mode Driver Framework 1.11 Download Offline InstallerĪll KMDF and UMDF 2 functionality is Universal Windows driver compliant. Universal Driver ComplianceĪll WDF driver samples and Visual Studio driver templates are Universal Windows driver compliant. For more information, see New support for source-level debugging of WDF code in Windows 10, 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.
KERNEL MODE DRIVER FRAMEWORK 1.11 WINDOWS 7 SOFTWARE
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. 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. Building a WDF driver for multiple versions of Windows.Added new API WdfDriverRetrieveDriverDataDirectoryString.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.
