In this article, we add a periodic Timer to the PCIe device previously simulated in Qemu. Once this Timer is enabled, it will trigger an MSI interrupt to the Qemu virtual machine every second. To verify that this interrupt function works correctly, we need to add interrupt handling capabilities to the driver for this PCIe … Read more
This article is a highlight from the Kanxue ForumAuthor from Kanxue ForumID: SSH Landscape Painting 1 Creating a Driver Project Creating the Project Reference article for WDK and VS installation: X86 Kernel Notes 0 Configuring Dual Machine Debugging Environment Open VS2017, create a new project, select Visual C++ -> Windows Drivers -> Legacy -> Empty … Read more
When writing WDF drivers, we often need to bind some driver-defined data structures to WDF objects (such as device objects, queue objects, request objects). These data structures provide the driver with the capability to store and manage state information specific to the object, which we commonly refer to as context. These contexts are essentially data … Read more
In the previous article, we implemented some PnP callbacks in PCI drivers, allowing the driver to load onto the PCIe device and enabling the device to enter the D3 low power state. In essence, writing a driver involves using the APIs provided by the operating system’s driver framework to create device objects and implement various … Read more
In the previous article, we introduced the driver code generated by the VS KMDF template, providing a preliminary understanding of the driver code. It should be evident that this driver is quite simple, essentially lacking any real functionality. After installing the driver we wrote, this PCIe device remains in the D0 state (if you are … Read more
The Windows WDF (Windows Driver Framework) is a driver development architecture introduced by Microsoft, designed to simplify the kernel driver development process and enhance system stability. WDF drivers are divided into KMDF (Kernel-Mode Driver Framework) and UMDF (User-Mode Driver Framework). KMDF provides an object-oriented interface for kernel-mode drivers, such as Device Objects, Queue Objects, Request … Read more
In the previous article, we introduced how to “write” a Windows PCI device driver from scratch. The term “write” is in quotes because we didn’t actually write any code; the driver code was generated using the KMDF template in Visual Studio. In this article, we will introduce the generated driver code. The first function to … Read more

Today, the AI Exploration Office will focus on the latest news and developments in AI and robotics both domestically and internationally, exploring the infinite possibilities in this field together. … Read more
In recent years, with the development of artificial intelligence and open-source hardware, there has been a surge of interest in “robots” in society. However, the robots that most people are familiar with seem to require extensive engineering and computer knowledge. So, are there any robots that are easy to DIY and accessible to the general … Read more
