Windows 10: Introducing Driver Module Framework

Brink · Aug 15, 2018

The Microsoft Devices team is excited to announce the release of an open source framework for Windows driver developers — Driver Module Framework (DMF). With DMF, not only can you easily develop simple and structured Windows Driver Framework (WDF) drivers but also share code amongst your drivers.

Background

Over the years Surface organization developed many products such as Pro, Studio, Laptop, Book with unique, innovative hardware capabilities. To light up these capabilities, we often needed to write drivers and firmware. Even though these products had commonalities in terms of how they interfaced with the hardware, individual product teams worked in isolation and built either their own drivers from scratch or copied based on their awareness of existing code and modified to suit their needs. This did help in meeting their immediate business priorities, but led to tremendous duplication of code and maintenance overhead. Developers with varied level of experience often created many divergent solutions to solve the same problem and the code lacked structure and quality.

About three years ago, the team decided to take a holistic look at drivers written for various Surface products and started an effort to structure code in a way that allows for maximum reuse of code with goals to improve the efficiency, serviceability, and scalability of teams to build new products.

We started by breaking down individual functionalities in drivers into a shareable code base. This iterative effort led to the creation of DMF: an extension to WDF that provides you with a library of new WDF Objects called DMF Modules. Modules allow interaction with one another, WDF, and hardware in a structured manner.

Today, all WDF drivers on the team are written by using DMF. Modules are well tested and can be reused or extended later to meet new requirements. Besides having the benefit of well-architected drivers, bug fixes are now efficient. A bug fix in a Module is automatically applied to all the drivers that were built using the Module.

As part of the open source effort, we have shared many Modules that provide solutions for commonly faced problems...

Bitlocker and Trusted Platform Module problems

We appreciate the screenshot you sent.

This issue usually occurs because the Trusted Platform Module (TPM)
uses the manufacturer driver and not the Windows built-in Trusted Platform Module driver.

To resolve this, you can manually uninstall and reinstall Trusted Platform Module. To do so, see the steps below:

Open Device Manager on the device on which you are experiencing the issue

Uninstall the Trusted Platform Module driver.

Give us an update after following the troubleshooting steps provided.
