In the previous article (Implementing a PCIe Device in Qemu: Adding a Periodic Timer to the Device), we introduced how to add a Timer to a PCIe device simulated by Qemu. This Timer has a counter that increments by 1 every second once enabled, and it also sends an interrupt to the virtual machine.To test … Read more
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
The Root of the Dilemma in Understanding Assembly Language For programmers who are “native” in C/C++, reading assembly code often encounters the following difficulties: Poor Readability: Assembly instructions have a low level of abstraction and lack the expressiveness of high-level languages. Lack of Context: Low-level details such as register operations and memory accesses obscure the … Read more
0x00 This chapter is dedicated to daily learning and note sharing to help everyone learn assembly language. Why learn assembly language? Because in red-blue confrontations, our tools are often detected and eliminated due to the presence of AV/EDR. Therefore, we need to counter AV, which involves evasion techniques. To learn evasion techniques, we must start … Read more

So, can using Rust really make software safer? System software … Read more
Hello everyone, I am the Intelligence Guy~ Modifying the MAC address is a common development requirement in network management and privacy protection. 1. Why Change the MAC Address? For example, when we replace a damaged network card, we need to restore the original MAC address to maintain IP allocation, firewall policies, and device authentication; there … Read more
Have you ever wondered why cloud computing giants like AWS, Alibaba Cloud, Huawei Cloud, and Google Cloud almost uniformly choose Linux as their underlying system? Isn’t Windows Server appealing? Today, we will unveil the “five key advantages” of Linux’s dominance in the cloud computing market, and by the end, you’ll understand why it is indispensable … Read more
