Overview VxWorks is a real-time operating system (RTOS) developed by Wind River, providing robust support for hardware interfaces, including Peripheral Component Interconnect (PCI) devices. Writing PCI device drivers in VxWorks involves interacting with the PCI bus, configuring devices, managing interrupts, and providing an access interface for applications. This guide will walk you through the process … Read more
The PCIe bus is designed as an evolution of the PCI bus, and understanding the PCIe bus begins with learning about PCI. The birth of the PCI (Peripheral Component Interconnect) bus is closely related to the rapid development of PCs (Personal Computers). In processor architecture, the PCI bus is categorized as a local bus. The … Read more
In patients with ST-segment elevation myocardial infarction (STEMI), approximately 50% have multivessel coronary artery disease, which is associated with an increased risk of recurrent myocardial infarction and death. The COMPLETE trial indicated that complete revascularization in patients with STEMI and multivessel coronary artery disease is superior to percutaneous coronary intervention (PCI) that only opens the … 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 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
Monitoring and Tuning the Linux Networking Stack: Receiving Data In Brief This blog post explains how computers running the Linux kernel receive packets and how to monitor and tune various components of the networking stack as packets flow from the network to user-space programs. Update: We have published a corresponding article: “Monitoring and Tuning the … Read more
