Currently, data has become the core resource driving innovation and development. The full release of data value requires efficient and secure data sharing between different entities. Among these, interoperability is a key element for achieving data sharing. To realize interoperability, technology-neutral protocols and standards are needed, allowing organizations to share data according to commonly recognized … Read more
1. Introduction to IPI Interrupts IPI interrupts, or Inter-Processor Interrupts, are essentially the SGI interrupts (Software Generated Interrupts) defined in the ARM GIC architecture. In the GICv3 architecture, there are a total of 16 SGI interrupts (excluding extensions), with interrupt numbers ranging from 0 to 15, as shown in the figure below. Inter-Processor Interrupts are … Read more
In the Armbian system, mounting disks is a common operation, but traditional mounting methods (such as directly modifying /etc/fstab) carry certain risks. If a disk fails to mount properly, it may lead to system failure or even damage. To avoid this situation, this article will introduce a safer and more stable mounting method: using UUID … Read more
The total word count is 2502 words Estimated reading time is about 5 minutes There are two types of IoT devices: high-end and low-end devices. The operating systems for high-end devices are fully functional, including Windows, Linux, or Android.
